1 00:00:00,000 --> 00:00:18,749 I 2 00:00:18,749 --> 00:00:18,759 3 00:00:18,759 --> 00:00:22,419 okay continuing with platings and 4 00:00:22,419 --> 00:00:22,429 okay continuing with platings and 5 00:00:22,429 --> 00:00:25,150 okay continuing with platings and coatings in the passivation and pre 6 00:00:25,150 --> 00:00:25,160 coatings in the passivation and pre 7 00:00:25,160 --> 00:00:28,540 coatings in the passivation and pre oxidation and right now perspiration so 8 00:00:28,540 --> 00:00:28,550 oxidation and right now perspiration so 9 00:00:28,550 --> 00:00:35,939 oxidation and right now perspiration so we'll get rid of the coat and proceed 10 00:00:35,939 --> 00:00:35,949 we'll get rid of the coat and proceed 11 00:00:35,949 --> 00:00:38,590 we'll get rid of the coat and proceed now stainless steel fasteners are 12 00:00:38,590 --> 00:00:38,600 now stainless steel fasteners are 13 00:00:38,600 --> 00:00:41,860 now stainless steel fasteners are normally passivated or pre oxidized 14 00:00:41,860 --> 00:00:41,870 normally passivated or pre oxidized 15 00:00:41,870 --> 00:00:44,020 normally passivated or pre oxidized during a manufacturing process to make 16 00:00:44,020 --> 00:00:44,030 during a manufacturing process to make 17 00:00:44,030 --> 00:00:47,170 during a manufacturing process to make them more inert and of course I 18 00:00:47,170 --> 00:00:47,180 them more inert and of course I 19 00:00:47,180 --> 00:00:49,749 them more inert and of course I mentioned earlier is done with the acid 20 00:00:49,749 --> 00:00:49,759 mentioned earlier is done with the acid 21 00:00:49,759 --> 00:00:52,299 mentioned earlier is done with the acid treatment and then of course the pre 22 00:00:52,299 --> 00:00:52,309 treatment and then of course the pre 23 00:00:52,309 --> 00:00:54,280 treatment and then of course the pre oxidation is just done simply by putting 24 00:00:54,280 --> 00:00:54,290 oxidation is just done simply by putting 25 00:00:54,290 --> 00:00:56,410 oxidation is just done simply by putting them in a furnace and run them up to 26 00:00:56,410 --> 00:00:56,420 them in a furnace and run them up to 27 00:00:56,420 --> 00:00:59,530 them in a furnace and run them up to about 1300 degrees and cooling them to 28 00:00:59,530 --> 00:00:59,540 about 1300 degrees and cooling them to 29 00:00:59,540 --> 00:01:02,350 about 1300 degrees and cooling them to form an oxide coating on the surface the 30 00:01:02,350 --> 00:01:02,360 form an oxide coating on the surface the 31 00:01:02,360 --> 00:01:04,600 form an oxide coating on the surface the advantages are that it deters galling 32 00:01:04,600 --> 00:01:04,610 advantages are that it deters galling 33 00:01:04,610 --> 00:01:06,969 advantages are that it deters galling and it's a relatively inexpensive 34 00:01:06,969 --> 00:01:06,979 and it's a relatively inexpensive 35 00:01:06,979 --> 00:01:09,969 and it's a relatively inexpensive process the disadvantage is that making 36 00:01:09,969 --> 00:01:09,979 process the disadvantage is that making 37 00:01:09,979 --> 00:01:12,069 process the disadvantage is that making parts still need to be lubricated for 38 00:01:12,069 --> 00:01:12,079 parts still need to be lubricated for 39 00:01:12,079 --> 00:01:18,340 parts still need to be lubricated for torque coefficient consistency and 40 00:01:18,340 --> 00:01:18,350 torque coefficient consistency and 41 00:01:18,350 --> 00:01:21,640 torque coefficient consistency and here's the old familiar black oxide 42 00:01:21,640 --> 00:01:21,650 here's the old familiar black oxide 43 00:01:21,650 --> 00:01:25,600 here's the old familiar black oxide coating with oil and it's nice and 44 00:01:25,600 --> 00:01:25,610 coating with oil and it's nice and 45 00:01:25,610 --> 00:01:27,760 coating with oil and it's nice and pretty in black and you put oil on it 46 00:01:27,760 --> 00:01:27,770 pretty in black and you put oil on it 47 00:01:27,770 --> 00:01:31,719 pretty in black and you put oil on it and it glistens and looks good but once 48 00:01:31,719 --> 00:01:31,729 and it glistens and looks good but once 49 00:01:31,729 --> 00:01:35,070 and it glistens and looks good but once the oil is gone black oxide is worthless 50 00:01:35,070 --> 00:01:35,080 the oil is gone black oxide is worthless 51 00:01:35,080 --> 00:01:40,960 the oil is gone black oxide is worthless it's real cheap no baking required after 52 00:01:40,960 --> 00:01:40,970 it's real cheap no baking required after 53 00:01:40,970 --> 00:01:43,330 it's real cheap no baking required after plating it this the material strength is 54 00:01:43,330 --> 00:01:43,340 plating it this the material strength is 55 00:01:43,340 --> 00:01:46,539 plating it this the material strength is less than 200 k SI and its disadvantages 56 00:01:46,539 --> 00:01:46,549 less than 200 k SI and its disadvantages 57 00:01:46,549 --> 00:01:47,980 less than 200 k SI and its disadvantages it's worthless for corrosion prevention 58 00:01:47,980 --> 00:01:47,990 it's worthless for corrosion prevention 59 00:01:47,990 --> 00:01:50,680 it's worthless for corrosion prevention once the oil is gone and the coating 60 00:01:50,680 --> 00:01:50,690 once the oil is gone and the coating 61 00:01:50,690 --> 00:01:57,700 once the oil is gone and the coating doesn't adhere well to steal now here's 62 00:01:57,700 --> 00:01:57,710 doesn't adhere well to steal now here's 63 00:01:57,710 --> 00:02:00,190 doesn't adhere well to steal now here's a bunch of miscellaneous platings and 64 00:02:00,190 --> 00:02:00,200 a bunch of miscellaneous platings and 65 00:02:00,200 --> 00:02:03,820 a bunch of miscellaneous platings and coatings and electric lyst nickel is one 66 00:02:03,820 --> 00:02:03,830 coatings and electric lyst nickel is one 67 00:02:03,830 --> 00:02:07,600 coatings and electric lyst nickel is one of them and it is used a lot on just 68 00:02:07,600 --> 00:02:07,610 of them and it is used a lot on just 69 00:02:07,610 --> 00:02:10,600 of them and it is used a lot on just coating of steel where you don't have 70 00:02:10,600 --> 00:02:10,610 coating of steel where you don't have 71 00:02:10,610 --> 00:02:16,240 coating of steel where you don't have threads but on threads it creates some 72 00:02:16,240 --> 00:02:16,250 threads but on threads it creates some 73 00:02:16,250 --> 00:02:19,390 threads but on threads it creates some problems in that you can get uneven 74 00:02:19,390 --> 00:02:19,400 problems in that you can get uneven 75 00:02:19,400 --> 00:02:21,369 problems in that you can get uneven plating on the threads so that they're 76 00:02:21,369 --> 00:02:21,379 plating on the threads so that they're 77 00:02:21,379 --> 00:02:24,070 plating on the threads so that they're kind of out of tolerance this sir Mattel 78 00:02:24,070 --> 00:02:24,080 kind of out of tolerance this sir Mattel 79 00:02:24,080 --> 00:02:30,369 kind of out of tolerance this sir Mattel sir Malloy is a aluminum inorganic 80 00:02:30,369 --> 00:02:30,379 sir Malloy is a aluminum inorganic 81 00:02:30,379 --> 00:02:31,030 sir Malloy is a aluminum inorganic material 82 00:02:31,030 --> 00:02:31,040 material 83 00:02:31,040 --> 00:02:34,449 material all that is used for corrosion 84 00:02:34,449 --> 00:02:34,459 all that is used for corrosion 85 00:02:34,459 --> 00:02:36,640 all that is used for corrosion protection of both unthreaded and 86 00:02:36,640 --> 00:02:36,650 protection of both unthreaded and 87 00:02:36,650 --> 00:02:40,199 protection of both unthreaded and threaded parts but once again if you 88 00:02:40,199 --> 00:02:40,209 threaded parts but once again if you 89 00:02:40,209 --> 00:02:43,509 threaded parts but once again if you assemble reassemble very many times it 90 00:02:43,509 --> 00:02:43,519 assemble reassemble very many times it 91 00:02:43,519 --> 00:02:46,300 assemble reassemble very many times it will come off synergistic because 92 00:02:46,300 --> 00:02:46,310 will come off synergistic because 93 00:02:46,310 --> 00:02:48,339 will come off synergistic because another one is a combination of surface 94 00:02:48,339 --> 00:02:48,349 another one is a combination of surface 95 00:02:48,349 --> 00:02:52,780 another one is a combination of surface oxidation and a fluoropolymer used for 96 00:02:52,780 --> 00:02:52,790 oxidation and a fluoropolymer used for 97 00:02:52,790 --> 00:02:56,080 oxidation and a fluoropolymer used for corrosion protection and lubricity but 98 00:02:56,080 --> 00:02:56,090 corrosion protection and lubricity but 99 00:02:56,090 --> 00:02:59,229 corrosion protection and lubricity but these are assembly reassembly none of 100 00:02:59,229 --> 00:02:59,239 these are assembly reassembly none of 101 00:02:59,239 --> 00:03:02,920 these are assembly reassembly none of these work that well on proposed 102 00:03:02,920 --> 00:03:02,930 these work that well on proposed 103 00:03:02,930 --> 00:03:05,640 these work that well on proposed replacements for cadmium of course the 104 00:03:05,640 --> 00:03:05,650 replacements for cadmium of course the 105 00:03:05,650 --> 00:03:10,240 replacements for cadmium of course the there's been a big push to do away with 106 00:03:10,240 --> 00:03:10,250 there's been a big push to do away with 107 00:03:10,250 --> 00:03:12,659 there's been a big push to do away with cadmium because it is such a bad thing 108 00:03:12,659 --> 00:03:12,669 cadmium because it is such a bad thing 109 00:03:12,669 --> 00:03:16,569 cadmium because it is such a bad thing environmentally so there's not fit over 110 00:03:16,569 --> 00:03:16,579 environmentally so there's not fit over 111 00:03:16,579 --> 00:03:18,610 environmentally so there's not fit over in chardon came up with this dr. Matt 112 00:03:18,610 --> 00:03:18,620 in chardon came up with this dr. Matt 113 00:03:18,620 --> 00:03:22,149 in chardon came up with this dr. Matt 320 with the plus a ol sealer as a 114 00:03:22,149 --> 00:03:22,159 320 with the plus a ol sealer as a 115 00:03:22,159 --> 00:03:24,399 320 with the plus a ol sealer as a proprietary thing for the automotive 116 00:03:24,399 --> 00:03:24,409 proprietary thing for the automotive 117 00:03:24,409 --> 00:03:29,949 proprietary thing for the automotive companies and it has metal oxide zinc 118 00:03:29,949 --> 00:03:29,959 companies and it has metal oxide zinc 119 00:03:29,959 --> 00:03:32,619 companies and it has metal oxide zinc and aluminum and a clear sealer it's 120 00:03:32,619 --> 00:03:32,629 and aluminum and a clear sealer it's 121 00:03:32,629 --> 00:03:35,379 and aluminum and a clear sealer it's good up to 600 degrees but the coating 122 00:03:35,379 --> 00:03:35,389 good up to 600 degrees but the coating 123 00:03:35,389 --> 00:03:37,869 good up to 600 degrees but the coating is damaged by assembly disassembly 124 00:03:37,869 --> 00:03:37,879 is damaged by assembly disassembly 125 00:03:37,879 --> 00:03:40,899 is damaged by assembly disassembly cycles and it will support fungus growth 126 00:03:40,899 --> 00:03:40,909 cycles and it will support fungus growth 127 00:03:40,909 --> 00:03:45,339 cycles and it will support fungus growth and it costs about the same as cadmium 128 00:03:45,339 --> 00:03:45,349 and it costs about the same as cadmium 129 00:03:45,349 --> 00:03:48,460 and it costs about the same as cadmium so the cost savings isn't there the only 130 00:03:48,460 --> 00:03:48,470 so the cost savings isn't there the only 131 00:03:48,470 --> 00:03:50,979 so the cost savings isn't there the only thing that it's kinder to the 132 00:03:50,979 --> 00:03:50,989 thing that it's kinder to the 133 00:03:50,989 --> 00:03:55,000 thing that it's kinder to the environment zinc nickel coating is one 134 00:03:55,000 --> 00:03:55,010 environment zinc nickel coating is one 135 00:03:55,010 --> 00:03:57,250 environment zinc nickel coating is one that is used some there's about ninety 136 00:03:57,250 --> 00:03:57,260 that is used some there's about ninety 137 00:03:57,260 --> 00:04:00,099 that is used some there's about ninety percent ten percent nickel but it 138 00:04:00,099 --> 00:04:00,109 percent ten percent nickel but it 139 00:04:00,109 --> 00:04:02,589 percent ten percent nickel but it doesn't work very well on fasteners it 140 00:04:02,589 --> 00:04:02,599 doesn't work very well on fasteners it 141 00:04:02,599 --> 00:04:04,649 doesn't work very well on fasteners it works on rods and things of this nature 142 00:04:04,649 --> 00:04:04,659 works on rods and things of this nature 143 00:04:04,659 --> 00:04:07,569 works on rods and things of this nature now here is a summary of pleadings and 144 00:04:07,569 --> 00:04:07,579 now here is a summary of pleadings and 145 00:04:07,579 --> 00:04:15,180 now here is a summary of pleadings and coatings and the thing that is most 146 00:04:15,180 --> 00:04:15,190 147 00:04:15,190 --> 00:04:18,849 important here is the useful design 148 00:04:18,849 --> 00:04:18,859 important here is the useful design 149 00:04:18,859 --> 00:04:21,370 important here is the useful design temperature limit you will notice that 150 00:04:21,370 --> 00:04:21,380 temperature limit you will notice that 151 00:04:21,380 --> 00:04:25,990 temperature limit you will notice that most of these don't go that high and the 152 00:04:25,990 --> 00:04:26,000 most of these don't go that high and the 153 00:04:26,000 --> 00:04:28,930 most of these don't go that high and the a here is for the black oxide with oil 154 00:04:28,930 --> 00:04:28,940 a here is for the black oxide with oil 155 00:04:28,940 --> 00:04:30,909 a here is for the black oxide with oil as soon as the oil boils off your 156 00:04:30,909 --> 00:04:30,919 as soon as the oil boils off your 157 00:04:30,919 --> 00:04:33,370 as soon as the oil boils off your corrosion resistance it's gone so you 158 00:04:33,370 --> 00:04:33,380 corrosion resistance it's gone so you 159 00:04:33,380 --> 00:04:38,200 corrosion resistance it's gone so you see when you get down to it about 1,200 160 00:04:38,200 --> 00:04:38,210 see when you get down to it about 1,200 161 00:04:38,210 --> 00:04:40,330 see when you get down to it about 1,200 degrees is the best that any of these 162 00:04:40,330 --> 00:04:40,340 degrees is the best that any of these 163 00:04:40,340 --> 00:04:43,540 degrees is the best that any of these will do so that's why that in a lot of 164 00:04:43,540 --> 00:04:43,550 will do so that's why that in a lot of 165 00:04:43,550 --> 00:04:44,770 will do so that's why that in a lot of cases where you 166 00:04:44,770 --> 00:04:44,780 cases where you 167 00:04:44,780 --> 00:04:48,129 cases where you super high temperatures you have to use 168 00:04:48,129 --> 00:04:48,139 super high temperatures you have to use 169 00:04:48,139 --> 00:04:50,770 super high temperatures you have to use a material that doesn't require coding 170 00:04:50,770 --> 00:04:50,780 a material that doesn't require coding 171 00:04:50,780 --> 00:04:53,890 a material that doesn't require coding like wasp a lawyer Hanes or inconel or 172 00:04:53,890 --> 00:04:53,900 like wasp a lawyer Hanes or inconel or 173 00:04:53,900 --> 00:04:56,650 like wasp a lawyer Hanes or inconel or something of that nature because you 174 00:04:56,650 --> 00:04:56,660 something of that nature because you 175 00:04:56,660 --> 00:04:59,820 something of that nature because you can't rely on the coatings now here's a 176 00:04:59,820 --> 00:04:59,830 can't rely on the coatings now here's a 177 00:04:59,830 --> 00:05:04,240 can't rely on the coatings now here's a table that just gives various 178 00:05:04,240 --> 00:05:04,250 table that just gives various 179 00:05:04,250 --> 00:05:08,680 table that just gives various characteristics of the coatings and 180 00:05:08,680 --> 00:05:08,690 characteristics of the coatings and 181 00:05:08,690 --> 00:05:10,210 characteristics of the coatings and plated there's a couple here that i 182 00:05:10,210 --> 00:05:10,220 plated there's a couple here that i 183 00:05:10,220 --> 00:05:15,090 plated there's a couple here that i wanted to mention era date is a common 184 00:05:15,090 --> 00:05:15,100 wanted to mention era date is a common 185 00:05:15,100 --> 00:05:18,940 wanted to mention era date is a common coating in fact we used it on the CM one 186 00:05:18,940 --> 00:05:18,950 coating in fact we used it on the CM one 187 00:05:18,950 --> 00:05:22,650 coating in fact we used it on the CM one chamber for it is electrically 188 00:05:22,650 --> 00:05:22,660 chamber for it is electrically 189 00:05:22,660 --> 00:05:26,800 chamber for it is electrically conductive whereas anodized isn't and it 190 00:05:26,800 --> 00:05:26,810 conductive whereas anodized isn't and it 191 00:05:26,810 --> 00:05:30,640 conductive whereas anodized isn't and it is a type of chromate conversion coating 192 00:05:30,640 --> 00:05:30,650 is a type of chromate conversion coating 193 00:05:30,650 --> 00:05:32,680 is a type of chromate conversion coating in which you actually treat the surface 194 00:05:32,680 --> 00:05:32,690 in which you actually treat the surface 195 00:05:32,690 --> 00:05:36,520 in which you actually treat the surface with an acid to form a real thin layer 196 00:05:36,520 --> 00:05:36,530 with an acid to form a real thin layer 197 00:05:36,530 --> 00:05:40,350 with an acid to form a real thin layer that is somewhat corrosion resistant so 198 00:05:40,350 --> 00:05:40,360 that is somewhat corrosion resistant so 199 00:05:40,360 --> 00:05:44,350 that is somewhat corrosion resistant so what we had to do in in on CM one you 200 00:05:44,350 --> 00:05:44,360 what we had to do in in on CM one you 201 00:05:44,360 --> 00:05:48,010 what we had to do in in on CM one you mask it in the irritated areas where you 202 00:05:48,010 --> 00:05:48,020 mask it in the irritated areas where you 203 00:05:48,020 --> 00:05:50,020 mask it in the irritated areas where you have electrical conductivity required 204 00:05:50,020 --> 00:05:50,030 have electrical conductivity required 205 00:05:50,030 --> 00:05:52,330 have electrical conductivity required and then the anodized which is actually 206 00:05:52,330 --> 00:05:52,340 and then the anodized which is actually 207 00:05:52,340 --> 00:05:54,070 and then the anodized which is actually used although it's used on other 208 00:05:54,070 --> 00:05:54,080 used although it's used on other 209 00:05:54,080 --> 00:05:57,310 used although it's used on other materials as we know it as being used on 210 00:05:57,310 --> 00:05:57,320 materials as we know it as being used on 211 00:05:57,320 --> 00:06:02,830 materials as we know it as being used on aluminum it is a acid etch using 212 00:06:02,830 --> 00:06:02,840 aluminum it is a acid etch using 213 00:06:02,840 --> 00:06:06,130 aluminum it is a acid etch using sulfuric acid I believe that forms a 214 00:06:06,130 --> 00:06:06,140 sulfuric acid I believe that forms a 215 00:06:06,140 --> 00:06:10,600 sulfuric acid I believe that forms a fairly heavy oxide coating and fact you 216 00:06:10,600 --> 00:06:10,610 fairly heavy oxide coating and fact you 217 00:06:10,610 --> 00:06:14,800 fairly heavy oxide coating and fact you can't anodized a fastener because the 218 00:06:14,800 --> 00:06:14,810 can't anodized a fastener because the 219 00:06:14,810 --> 00:06:17,200 can't anodized a fastener because the anodized is thick and well you can 220 00:06:17,200 --> 00:06:17,210 anodized is thick and well you can 221 00:06:17,210 --> 00:06:19,090 anodized is thick and well you can anodized it physically but it doesn't 222 00:06:19,090 --> 00:06:19,100 anodized it physically but it doesn't 223 00:06:19,100 --> 00:06:20,740 anodized it physically but it doesn't work out very well on the threaded areas 224 00:06:20,740 --> 00:06:20,750 work out very well on the threaded areas 225 00:06:20,750 --> 00:06:22,719 work out very well on the threaded areas because you will have a to heavier 226 00:06:22,719 --> 00:06:22,729 because you will have a to heavier 227 00:06:22,729 --> 00:06:24,400 because you will have a to heavier coating and the threads where it doesn't 228 00:06:24,400 --> 00:06:24,410 coating and the threads where it doesn't 229 00:06:24,410 --> 00:06:29,230 coating and the threads where it doesn't work too well now moving on to thread 230 00:06:29,230 --> 00:06:29,240 work too well now moving on to thread 231 00:06:29,240 --> 00:06:32,170 work too well now moving on to thread lubricants there's all kinds of 232 00:06:32,170 --> 00:06:32,180 lubricants there's all kinds of 233 00:06:32,180 --> 00:06:34,450 lubricants there's all kinds of lubricants available and of course all 234 00:06:34,450 --> 00:06:34,460 lubricants available and of course all 235 00:06:34,460 --> 00:06:40,830 lubricants available and of course all of us have used the old 10w30 oil and 236 00:06:40,830 --> 00:06:40,840 of us have used the old 10w30 oil and 237 00:06:40,840 --> 00:06:45,190 of us have used the old 10w30 oil and for our cars to lubricate stuff the oil 238 00:06:45,190 --> 00:06:45,200 for our cars to lubricate stuff the oil 239 00:06:45,200 --> 00:06:49,990 for our cars to lubricate stuff the oil grease wax graphite silver molybdenum 240 00:06:49,990 --> 00:06:50,000 grease wax graphite silver molybdenum 241 00:06:50,000 --> 00:06:53,230 grease wax graphite silver molybdenum disulphide and prep proprietary types 242 00:06:53,230 --> 00:06:53,240 disulphide and prep proprietary types 243 00:06:53,240 --> 00:06:55,290 disulphide and prep proprietary types such as never sees silver goop 244 00:06:55,290 --> 00:06:55,300 such as never sees silver goop 245 00:06:55,300 --> 00:06:57,600 such as never sees silver goop synergistic can ever lube and so 246 00:06:57,600 --> 00:06:57,610 synergistic can ever lube and so 247 00:06:57,610 --> 00:06:59,820 synergistic can ever lube and so on some of these are applied at 248 00:06:59,820 --> 00:06:59,830 on some of these are applied at 249 00:06:59,830 --> 00:07:01,740 on some of these are applied at installation and some are cured on the 250 00:07:01,740 --> 00:07:01,750 installation and some are cured on the 251 00:07:01,750 --> 00:07:09,929 installation and some are cured on the fastener by the manufacturer I'm having 252 00:07:09,929 --> 00:07:09,939 fastener by the manufacturer I'm having 253 00:07:09,939 --> 00:07:13,770 fastener by the manufacturer I'm having trouble turning my page okay for oil and 254 00:07:13,770 --> 00:07:13,780 trouble turning my page okay for oil and 255 00:07:13,780 --> 00:07:17,760 trouble turning my page okay for oil and grease you have good lubrication up to 256 00:07:17,760 --> 00:07:17,770 grease you have good lubrication up to 257 00:07:17,770 --> 00:07:19,409 grease you have good lubrication up to the boiling point of the oil or grease 258 00:07:19,409 --> 00:07:19,419 the boiling point of the oil or grease 259 00:07:19,419 --> 00:07:22,499 the boiling point of the oil or grease which is usually around 250 degrees and 260 00:07:22,499 --> 00:07:22,509 which is usually around 250 degrees and 261 00:07:22,509 --> 00:07:23,850 which is usually around 250 degrees and of course you can't use any of this 262 00:07:23,850 --> 00:07:23,860 of course you can't use any of this 263 00:07:23,860 --> 00:07:27,920 of course you can't use any of this stuff in vacuum now graphite graphite 264 00:07:27,920 --> 00:07:27,930 stuff in vacuum now graphite graphite 265 00:07:27,930 --> 00:07:32,309 stuff in vacuum now graphite graphite drag graphite is not dry it's a fine 266 00:07:32,309 --> 00:07:32,319 drag graphite is not dry it's a fine 267 00:07:32,319 --> 00:07:36,230 drag graphite is not dry it's a fine carbon powder that needs moisture 268 00:07:36,230 --> 00:07:36,240 269 00:07:36,240 --> 00:07:38,429 usually oil or water to become a 270 00:07:38,429 --> 00:07:38,439 usually oil or water to become a 271 00:07:38,439 --> 00:07:40,140 usually oil or water to become a lubricant and then when the moisture 272 00:07:40,140 --> 00:07:40,150 lubricant and then when the moisture 273 00:07:40,150 --> 00:07:42,480 lubricant and then when the moisture evaporates it becomes an abrasive powder 274 00:07:42,480 --> 00:07:42,490 evaporates it becomes an abrasive powder 275 00:07:42,490 --> 00:07:45,390 evaporates it becomes an abrasive powder and of course it can't be using a vacuum 276 00:07:45,390 --> 00:07:45,400 and of course it can't be using a vacuum 277 00:07:45,400 --> 00:07:54,300 and of course it can't be using a vacuum either silver plating as I mentioned 278 00:07:54,300 --> 00:07:54,310 either silver plating as I mentioned 279 00:07:54,310 --> 00:07:59,330 either silver plating as I mentioned earlier it is normally used on stainless 280 00:07:59,330 --> 00:07:59,340 earlier it is normally used on stainless 281 00:07:59,340 --> 00:08:02,640 earlier it is normally used on stainless nuts stainless bolts as both a lubricant 282 00:08:02,640 --> 00:08:02,650 nuts stainless bolts as both a lubricant 283 00:08:02,650 --> 00:08:05,010 nuts stainless bolts as both a lubricant and I Colleen coating and it's good up 284 00:08:05,010 --> 00:08:05,020 and I Colleen coating and it's good up 285 00:08:05,020 --> 00:08:07,350 and I Colleen coating and it's good up to about 1600 degrees it can be used in 286 00:08:07,350 --> 00:08:07,360 to about 1600 degrees it can be used in 287 00:08:07,360 --> 00:08:10,430 to about 1600 degrees it can be used in a vacuum but it is very expensive 288 00:08:10,430 --> 00:08:10,440 a vacuum but it is very expensive 289 00:08:10,440 --> 00:08:13,050 a vacuum but it is very expensive molybdenum disulfide is kind of a 290 00:08:13,050 --> 00:08:13,060 molybdenum disulfide is kind of a 291 00:08:13,060 --> 00:08:15,059 molybdenum disulfide is kind of a universal tape that's used in the 292 00:08:15,059 --> 00:08:15,069 universal tape that's used in the 293 00:08:15,069 --> 00:08:18,360 universal tape that's used in the aerospace industry because it's a can be 294 00:08:18,360 --> 00:08:18,370 aerospace industry because it's a can be 295 00:08:18,370 --> 00:08:20,939 aerospace industry because it's a can be put on us a dry film lubricant it's good 296 00:08:20,939 --> 00:08:20,949 put on us a dry film lubricant it's good 297 00:08:20,949 --> 00:08:23,790 put on us a dry film lubricant it's good up to 750 degrees it can be used in a 298 00:08:23,790 --> 00:08:23,800 up to 750 degrees it can be used in a 299 00:08:23,800 --> 00:08:26,879 up to 750 degrees it can be used in a vacuum and it can be applied to both 300 00:08:26,879 --> 00:08:26,889 vacuum and it can be applied to both 301 00:08:26,889 --> 00:08:32,730 vacuum and it can be applied to both alloy steel and stainless steel now 302 00:08:32,730 --> 00:08:32,740 alloy steel and stainless steel now 303 00:08:32,740 --> 00:08:36,959 alloy steel and stainless steel now never sees is a proprietary petroleum 304 00:08:36,959 --> 00:08:36,969 never sees is a proprietary petroleum 305 00:08:36,969 --> 00:08:41,310 never sees is a proprietary petroleum based lubricant and it contains metal 306 00:08:41,310 --> 00:08:41,320 based lubricant and it contains metal 307 00:08:41,320 --> 00:08:45,960 based lubricant and it contains metal oxide usually copper or nickel depending 308 00:08:45,960 --> 00:08:45,970 oxide usually copper or nickel depending 309 00:08:45,970 --> 00:08:49,250 oxide usually copper or nickel depending on what temperature you want because the 310 00:08:49,250 --> 00:08:49,260 on what temperature you want because the 311 00:08:49,260 --> 00:08:51,900 on what temperature you want because the copper of course has a lower melting 312 00:08:51,900 --> 00:08:51,910 copper of course has a lower melting 313 00:08:51,910 --> 00:08:54,689 copper of course has a lower melting point than the nickel and it's good up 314 00:08:54,689 --> 00:08:54,699 point than the nickel and it's good up 315 00:08:54,699 --> 00:08:58,290 point than the nickel and it's good up to 2,200 degrees because what you wind 316 00:08:58,290 --> 00:08:58,300 to 2,200 degrees because what you wind 317 00:08:58,300 --> 00:09:00,449 to 2,200 degrees because what you wind up with is the metal flakes between the 318 00:09:00,449 --> 00:09:00,459 up with is the metal flakes between the 319 00:09:00,459 --> 00:09:04,860 up with is the metal flakes between the threads as the oil it boils off and so 320 00:09:04,860 --> 00:09:04,870 threads as the oil it boils off and so 321 00:09:04,870 --> 00:09:07,260 threads as the oil it boils off and so this means that you have to reapply each 322 00:09:07,260 --> 00:09:07,270 this means that you have to reapply each 323 00:09:07,270 --> 00:09:09,780 this means that you have to reapply each time you reassemble it and it can't be 324 00:09:09,780 --> 00:09:09,790 time you reassemble it and it can't be 325 00:09:09,790 --> 00:09:11,310 time you reassemble it and it can't be using a vacuum either but 326 00:09:11,310 --> 00:09:11,320 using a vacuum either but 327 00:09:11,320 --> 00:09:13,350 using a vacuum either but you have the the flakes in between the 328 00:09:13,350 --> 00:09:13,360 you have the the flakes in between the 329 00:09:13,360 --> 00:09:14,960 you have the the flakes in between the threads making them easier to 330 00:09:14,960 --> 00:09:14,970 threads making them easier to 331 00:09:14,970 --> 00:09:21,600 threads making them easier to disassemble silver goop which is made by 332 00:09:21,600 --> 00:09:21,610 disassemble silver goop which is made by 333 00:09:21,610 --> 00:09:25,190 disassemble silver goop which is made by some company here in Cleveland I believe 334 00:09:25,190 --> 00:09:25,200 some company here in Cleveland I believe 335 00:09:25,200 --> 00:09:30,750 some company here in Cleveland I believe is a proprietary paste that contains 336 00:09:30,750 --> 00:09:30,760 is a proprietary paste that contains 337 00:09:30,760 --> 00:09:33,540 is a proprietary paste that contains twenty to thirty percent silver and it's 338 00:09:33,540 --> 00:09:33,550 twenty to thirty percent silver and it's 339 00:09:33,550 --> 00:09:36,420 twenty to thirty percent silver and it's good up to about 1500 degrees but of 340 00:09:36,420 --> 00:09:36,430 good up to about 1500 degrees but of 341 00:09:36,430 --> 00:09:40,550 good up to about 1500 degrees but of course silver does not is corrosive to 342 00:09:40,550 --> 00:09:40,560 course silver does not is corrosive to 343 00:09:40,560 --> 00:09:44,130 course silver does not is corrosive to aluminum magnesium so you don't don't 344 00:09:44,130 --> 00:09:44,140 aluminum magnesium so you don't don't 345 00:09:44,140 --> 00:09:48,480 aluminum magnesium so you don't don't use it on them it's curse the silver 346 00:09:48,480 --> 00:09:48,490 use it on them it's curse the silver 347 00:09:48,490 --> 00:09:50,550 use it on them it's curse the silver goop is very expensive and it can't be 348 00:09:50,550 --> 00:09:50,560 goop is very expensive and it can't be 349 00:09:50,560 --> 00:09:55,770 goop is very expensive and it can't be using a vacuum either the fluorocarbon 350 00:09:55,770 --> 00:09:55,780 using a vacuum either the fluorocarbon 351 00:09:55,780 --> 00:09:59,730 using a vacuum either the fluorocarbon coatings there's a lot of them available 352 00:09:59,730 --> 00:09:59,740 coatings there's a lot of them available 353 00:09:59,740 --> 00:10:02,760 coatings there's a lot of them available the I'm just listing a few of them here 354 00:10:02,760 --> 00:10:02,770 the I'm just listing a few of them here 355 00:10:02,770 --> 00:10:05,460 the I'm just listing a few of them here the synergistic span coke style garden 356 00:10:05,460 --> 00:10:05,470 the synergistic span coke style garden 357 00:10:05,470 --> 00:10:08,670 the synergistic span coke style garden ever lube and they're only good for a 358 00:10:08,670 --> 00:10:08,680 ever lube and they're only good for a 359 00:10:08,680 --> 00:10:12,420 ever lube and they're only good for a few assemblies because they flake off if 360 00:10:12,420 --> 00:10:12,430 few assemblies because they flake off if 361 00:10:12,430 --> 00:10:16,610 few assemblies because they flake off if you assemble and disassemble a fastener 362 00:10:16,610 --> 00:10:16,620 you assemble and disassemble a fastener 363 00:10:16,620 --> 00:10:19,890 you assemble and disassemble a fastener nut bolt very much and there are only 364 00:10:19,890 --> 00:10:19,900 nut bolt very much and there are only 365 00:10:19,900 --> 00:10:22,980 nut bolt very much and there are only good up to about 400 degrees they can be 366 00:10:22,980 --> 00:10:22,990 good up to about 400 degrees they can be 367 00:10:22,990 --> 00:10:25,980 good up to about 400 degrees they can be used in a vacuum and here was one that I 368 00:10:25,980 --> 00:10:25,990 used in a vacuum and here was one that I 369 00:10:25,990 --> 00:10:29,520 used in a vacuum and here was one that I learned when I was looking for different 370 00:10:29,520 --> 00:10:29,530 learned when I was looking for different 371 00:10:29,530 --> 00:10:32,160 learned when I was looking for different types of lubricants for high temperature 372 00:10:32,160 --> 00:10:32,170 types of lubricants for high temperature 373 00:10:32,170 --> 00:10:35,630 types of lubricants for high temperature applications plain ol milk of magnesia 374 00:10:35,630 --> 00:10:35,640 applications plain ol milk of magnesia 375 00:10:35,640 --> 00:10:39,750 applications plain ol milk of magnesia is used by the turbine engine companies 376 00:10:39,750 --> 00:10:39,760 is used by the turbine engine companies 377 00:10:39,760 --> 00:10:42,840 is used by the turbine engine companies for engine assembly because anything 378 00:10:42,840 --> 00:10:42,850 for engine assembly because anything 379 00:10:42,850 --> 00:10:45,180 for engine assembly because anything that you use in a jet engine for 380 00:10:45,180 --> 00:10:45,190 that you use in a jet engine for 381 00:10:45,190 --> 00:10:46,910 that you use in a jet engine for lubricants going to burn off anyway 382 00:10:46,910 --> 00:10:46,920 lubricants going to burn off anyway 383 00:10:46,920 --> 00:10:49,170 lubricants going to burn off anyway after the things operating but in 384 00:10:49,170 --> 00:10:49,180 after the things operating but in 385 00:10:49,180 --> 00:10:52,400 after the things operating but in putting it together this is a suitable 386 00:10:52,400 --> 00:10:52,410 putting it together this is a suitable 387 00:10:52,410 --> 00:10:54,390 putting it together this is a suitable lubricant and it doesn't harm anything 388 00:10:54,390 --> 00:10:54,400 lubricant and it doesn't harm anything 389 00:10:54,400 --> 00:10:59,030 lubricant and it doesn't harm anything when it burns up now here's a summary of 390 00:10:59,030 --> 00:10:59,040 when it burns up now here's a summary of 391 00:10:59,040 --> 00:11:05,550 when it burns up now here's a summary of the thread lubricants and most of stuff 392 00:11:05,550 --> 00:11:05,560 the thread lubricants and most of stuff 393 00:11:05,560 --> 00:11:08,610 the thread lubricants and most of stuff we have covered here there this is 394 00:11:08,610 --> 00:11:08,620 we have covered here there this is 395 00:11:08,620 --> 00:11:11,670 we have covered here there this is doesn't necessarily include all of them 396 00:11:11,670 --> 00:11:11,680 doesn't necessarily include all of them 397 00:11:11,680 --> 00:11:15,300 doesn't necessarily include all of them but these are the the common ones and 398 00:11:15,300 --> 00:11:15,310 but these are the the common ones and 399 00:11:15,310 --> 00:11:19,560 but these are the the common ones and once again there's very few that are 400 00:11:19,560 --> 00:11:19,570 once again there's very few that are 401 00:11:19,570 --> 00:11:22,260 once again there's very few that are good for high temperatures here are the 402 00:11:22,260 --> 00:11:22,270 good for high temperatures here are the 403 00:11:22,270 --> 00:11:23,520 good for high temperatures here are the three that are good for the high 404 00:11:23,520 --> 00:11:23,530 three that are good for the high 405 00:11:23,530 --> 00:11:24,840 three that are good for the high temperatures so 406 00:11:24,840 --> 00:11:24,850 temperatures so 407 00:11:24,850 --> 00:11:25,920 temperatures so this is something you have to keep in 408 00:11:25,920 --> 00:11:25,930 this is something you have to keep in 409 00:11:25,930 --> 00:11:27,949 this is something you have to keep in mind that going back to that original 410 00:11:27,949 --> 00:11:27,959 mind that going back to that original 411 00:11:27,959 --> 00:11:31,170 mind that going back to that original principle that the first thing you want 412 00:11:31,170 --> 00:11:31,180 principle that the first thing you want 413 00:11:31,180 --> 00:11:33,090 principle that the first thing you want to do is establish the environment that 414 00:11:33,090 --> 00:11:33,100 to do is establish the environment that 415 00:11:33,100 --> 00:11:36,050 to do is establish the environment that you're going to have your fasteners in 416 00:11:36,050 --> 00:11:36,060 you're going to have your fasteners in 417 00:11:36,060 --> 00:11:39,569 you're going to have your fasteners in now going into the subject of corrosion 418 00:11:39,569 --> 00:11:39,579 now going into the subject of corrosion 419 00:11:39,579 --> 00:11:42,900 now going into the subject of corrosion of course this is a major field so we 420 00:11:42,900 --> 00:11:42,910 of course this is a major field so we 421 00:11:42,910 --> 00:11:45,809 of course this is a major field so we just try to hit it a little here in the 422 00:11:45,809 --> 00:11:45,819 just try to hit it a little here in the 423 00:11:45,819 --> 00:11:48,720 just try to hit it a little here in the way of fastener corrosion galvanic and 424 00:11:48,720 --> 00:11:48,730 way of fastener corrosion galvanic and 425 00:11:48,730 --> 00:11:50,610 way of fastener corrosion galvanic and stress corrosion we've already covered 426 00:11:50,610 --> 00:11:50,620 stress corrosion we've already covered 427 00:11:50,620 --> 00:11:55,110 stress corrosion we've already covered and the corrosion resistance of a 428 00:11:55,110 --> 00:11:55,120 and the corrosion resistance of a 429 00:11:55,120 --> 00:11:57,600 and the corrosion resistance of a particular metal to occur rodent can be 430 00:11:57,600 --> 00:11:57,610 particular metal to occur rodent can be 431 00:11:57,610 --> 00:12:01,350 particular metal to occur rodent can be found in a book of tables which I will 432 00:12:01,350 --> 00:12:01,360 found in a book of tables which I will 433 00:12:01,360 --> 00:12:03,269 found in a book of tables which I will be leaving behind when I retire there is 434 00:12:03,269 --> 00:12:03,279 be leaving behind when I retire there is 435 00:12:03,279 --> 00:12:06,870 be leaving behind when I retire there is a two-volume set that actually gives for 436 00:12:06,870 --> 00:12:06,880 a two-volume set that actually gives for 437 00:12:06,880 --> 00:12:10,350 a two-volume set that actually gives for the different percentages of different 438 00:12:10,350 --> 00:12:10,360 the different percentages of different 439 00:12:10,360 --> 00:12:12,569 the different percentages of different types of corrodens it gives the effect 440 00:12:12,569 --> 00:12:12,579 types of corrodens it gives the effect 441 00:12:12,579 --> 00:12:17,939 types of corrodens it gives the effect on the various materials and hydrogen 442 00:12:17,939 --> 00:12:17,949 on the various materials and hydrogen 443 00:12:17,949 --> 00:12:19,559 on the various materials and hydrogen embrittlement and graphite corrosion 444 00:12:19,559 --> 00:12:19,569 embrittlement and graphite corrosion 445 00:12:19,569 --> 00:12:21,840 embrittlement and graphite corrosion will be covered in the corrosion section 446 00:12:21,840 --> 00:12:21,850 will be covered in the corrosion section 447 00:12:21,850 --> 00:12:28,949 will be covered in the corrosion section here hydrogen embrittlement it's talked 448 00:12:28,949 --> 00:12:28,959 here hydrogen embrittlement it's talked 449 00:12:28,959 --> 00:12:33,329 here hydrogen embrittlement it's talked about a lot in recent years and yet you 450 00:12:33,329 --> 00:12:33,339 about a lot in recent years and yet you 451 00:12:33,339 --> 00:12:35,490 about a lot in recent years and yet you can test for it but it's kind of UFO 452 00:12:35,490 --> 00:12:35,500 can test for it but it's kind of UFO 453 00:12:35,500 --> 00:12:40,370 can test for it but it's kind of UFO like a UFO it's kind of hard to find 454 00:12:40,370 --> 00:12:40,380 455 00:12:40,380 --> 00:12:45,509 it's caused by having free hydrogen ions 456 00:12:45,509 --> 00:12:45,519 it's caused by having free hydrogen ions 457 00:12:45,519 --> 00:12:47,879 it's caused by having free hydrogen ions in the presence of the metal which in 458 00:12:47,879 --> 00:12:47,889 in the presence of the metal which in 459 00:12:47,889 --> 00:12:50,100 in the presence of the metal which in most of the time it's steel it causes 460 00:12:50,100 --> 00:12:50,110 most of the time it's steel it causes 461 00:12:50,110 --> 00:12:53,189 most of the time it's steel it causes problems in during the manufacturing or 462 00:12:53,189 --> 00:12:53,199 problems in during the manufacturing or 463 00:12:53,199 --> 00:12:55,740 problems in during the manufacturing or plating process the higher the strength 464 00:12:55,740 --> 00:12:55,750 plating process the higher the strength 465 00:12:55,750 --> 00:12:57,569 plating process the higher the strength of the material the more sensitive it is 466 00:12:57,569 --> 00:12:57,579 of the material the more sensitive it is 467 00:12:57,579 --> 00:13:00,329 of the material the more sensitive it is the hydrogen embrittlement you can get a 468 00:13:00,329 --> 00:13:00,339 the hydrogen embrittlement you can get a 469 00:13:00,339 --> 00:13:03,569 the hydrogen embrittlement you can get a hydrogen chemical reaction in which it 470 00:13:03,569 --> 00:13:03,579 hydrogen chemical reaction in which it 471 00:13:03,579 --> 00:13:06,179 hydrogen chemical reaction in which it combines with the carbon in the steel to 472 00:13:06,179 --> 00:13:06,189 combines with the carbon in the steel to 473 00:13:06,189 --> 00:13:12,900 combines with the carbon in the steel to form methane gas or are hydrogen niobium 474 00:13:12,900 --> 00:13:12,910 form methane gas or are hydrogen niobium 475 00:13:12,910 --> 00:13:15,300 form methane gas or are hydrogen niobium columbium same thing the English call it 476 00:13:15,300 --> 00:13:15,310 columbium same thing the English call it 477 00:13:15,310 --> 00:13:17,670 columbium same thing the English call it niobium the Americans call it Colombian 478 00:13:17,670 --> 00:13:17,680 niobium the Americans call it Colombian 479 00:13:17,680 --> 00:13:22,110 niobium the Americans call it Colombian or tantalum to form hydrides the methane 480 00:13:22,110 --> 00:13:22,120 or tantalum to form hydrides the methane 481 00:13:22,120 --> 00:13:26,069 or tantalum to form hydrides the methane gas can cause cracks and the hydrides 482 00:13:26,069 --> 00:13:26,079 gas can cause cracks and the hydrides 483 00:13:26,079 --> 00:13:29,220 gas can cause cracks and the hydrides are weaker than the parent material so 484 00:13:29,220 --> 00:13:29,230 are weaker than the parent material so 485 00:13:29,230 --> 00:13:32,100 are weaker than the parent material so they can weaken the material then you 486 00:13:32,100 --> 00:13:32,110 they can weaken the material then you 487 00:13:32,110 --> 00:13:34,740 they can weaken the material then you can get hydrogen blistering where the 488 00:13:34,740 --> 00:13:34,750 can get hydrogen blistering where the 489 00:13:34,750 --> 00:13:37,019 can get hydrogen blistering where the atomic hydrogen fuses into the material 490 00:13:37,019 --> 00:13:37,029 atomic hydrogen fuses into the material 491 00:13:37,029 --> 00:13:38,500 atomic hydrogen fuses into the material and combines in the moloch 492 00:13:38,500 --> 00:13:38,510 and combines in the moloch 493 00:13:38,510 --> 00:13:40,750 and combines in the moloch tools and then the molecule is bigger so 494 00:13:40,750 --> 00:13:40,760 tools and then the molecule is bigger so 495 00:13:40,760 --> 00:13:43,210 tools and then the molecule is bigger so it can't get back out so it will build 496 00:13:43,210 --> 00:13:43,220 it can't get back out so it will build 497 00:13:43,220 --> 00:13:45,610 it can't get back out so it will build up pressure to create blisters that will 498 00:13:45,610 --> 00:13:45,620 up pressure to create blisters that will 499 00:13:45,620 --> 00:13:48,700 up pressure to create blisters that will eventually cause cracks and here's the 500 00:13:48,700 --> 00:13:48,710 eventually cause cracks and here's the 501 00:13:48,710 --> 00:13:52,330 eventually cause cracks and here's the problem there's no external indication 502 00:13:52,330 --> 00:13:52,340 problem there's no external indication 503 00:13:52,340 --> 00:13:54,160 problem there's no external indication that hydrogen is present you can't look 504 00:13:54,160 --> 00:13:54,170 that hydrogen is present you can't look 505 00:13:54,170 --> 00:13:56,470 that hydrogen is present you can't look at it you can't run it through x-ray 506 00:13:56,470 --> 00:13:56,480 at it you can't run it through x-ray 507 00:13:56,480 --> 00:13:59,770 at it you can't run it through x-ray machine anything like that and find out 508 00:13:59,770 --> 00:13:59,780 machine anything like that and find out 509 00:13:59,780 --> 00:14:04,210 machine anything like that and find out that it's there so the only thing that 510 00:14:04,210 --> 00:14:04,220 that it's there so the only thing that 511 00:14:04,220 --> 00:14:08,050 that it's there so the only thing that you can do is test for it enjoy they 512 00:14:08,050 --> 00:14:08,060 you can do is test for it enjoy they 513 00:14:08,060 --> 00:14:10,480 you can do is test for it enjoy they test fasteners for hydrogen 514 00:14:10,480 --> 00:14:10,490 test fasteners for hydrogen 515 00:14:10,490 --> 00:14:13,590 test fasteners for hydrogen embrittlement they put them on a fixture 516 00:14:13,590 --> 00:14:13,600 embrittlement they put them on a fixture 517 00:14:13,600 --> 00:14:17,230 embrittlement they put them on a fixture there's an ASTM spec which I'm not don't 518 00:14:17,230 --> 00:14:17,240 there's an ASTM spec which I'm not don't 519 00:14:17,240 --> 00:14:19,060 there's an ASTM spec which I'm not don't remember the number of it you actually 520 00:14:19,060 --> 00:14:19,070 remember the number of it you actually 521 00:14:19,070 --> 00:14:24,870 remember the number of it you actually put them on with a wedge type washer and 522 00:14:24,870 --> 00:14:24,880 put them on with a wedge type washer and 523 00:14:24,880 --> 00:14:28,240 put them on with a wedge type washer and take them down and leave them for I 524 00:14:28,240 --> 00:14:28,250 take them down and leave them for I 525 00:14:28,250 --> 00:14:30,460 take them down and leave them for I think it's 48 hours or something like 526 00:14:30,460 --> 00:14:30,470 think it's 48 hours or something like 527 00:14:30,470 --> 00:14:34,270 think it's 48 hours or something like that if the head didn't pop off it 528 00:14:34,270 --> 00:14:34,280 that if the head didn't pop off it 529 00:14:34,280 --> 00:14:38,590 that if the head didn't pop off it passed the test and that's that's so 530 00:14:38,590 --> 00:14:38,600 passed the test and that's that's so 531 00:14:38,600 --> 00:14:41,470 passed the test and that's that's so what they do on testing for hydrogen 532 00:14:41,470 --> 00:14:41,480 what they do on testing for hydrogen 533 00:14:41,480 --> 00:14:42,730 what they do on testing for hydrogen embrittlement is just take a bunch of 534 00:14:42,730 --> 00:14:42,740 embrittlement is just take a bunch of 535 00:14:42,740 --> 00:14:45,480 embrittlement is just take a bunch of samples and test them that way to see if 536 00:14:45,480 --> 00:14:45,490 samples and test them that way to see if 537 00:14:45,490 --> 00:14:48,490 samples and test them that way to see if if they can find where any of them have 538 00:14:48,490 --> 00:14:48,500 if they can find where any of them have 539 00:14:48,500 --> 00:14:50,790 if they can find where any of them have embrittlement now on hydrogen 540 00:14:50,790 --> 00:14:50,800 embrittlement now on hydrogen 541 00:14:50,800 --> 00:14:54,370 embrittlement now on hydrogen environment embrittlement usually you 542 00:14:54,370 --> 00:14:54,380 environment embrittlement usually you 543 00:14:54,380 --> 00:14:55,900 environment embrittlement usually you wouldn't run into that because it takes 544 00:14:55,900 --> 00:14:55,910 wouldn't run into that because it takes 545 00:14:55,910 --> 00:14:59,800 wouldn't run into that because it takes high-pressure hydrogen to cause that so 546 00:14:59,800 --> 00:14:59,810 high-pressure hydrogen to cause that so 547 00:14:59,810 --> 00:15:02,170 high-pressure hydrogen to cause that so if you had a tank of some kind of high 548 00:15:02,170 --> 00:15:02,180 if you had a tank of some kind of high 549 00:15:02,180 --> 00:15:03,790 if you had a tank of some kind of high pressure tank that you had fasteners 550 00:15:03,790 --> 00:15:03,800 pressure tank that you had fasteners 551 00:15:03,800 --> 00:15:06,430 pressure tank that you had fasteners holding something together inside then 552 00:15:06,430 --> 00:15:06,440 holding something together inside then 553 00:15:06,440 --> 00:15:11,230 holding something together inside then you could actually get hydrogen into the 554 00:15:11,230 --> 00:15:11,240 you could actually get hydrogen into the 555 00:15:11,240 --> 00:15:13,270 you could actually get hydrogen into the fasteners just from the high pressure in 556 00:15:13,270 --> 00:15:13,280 fasteners just from the high pressure in 557 00:15:13,280 --> 00:15:14,920 fasteners just from the high pressure in other words we're assuming there there 558 00:15:14,920 --> 00:15:14,930 other words we're assuming there there 559 00:15:14,930 --> 00:15:16,720 other words we're assuming there there was no hydrogen embrittlement in the 560 00:15:16,720 --> 00:15:16,730 was no hydrogen embrittlement in the 561 00:15:16,730 --> 00:15:18,790 was no hydrogen embrittlement in the fastener before it was installed then 562 00:15:18,790 --> 00:15:18,800 fastener before it was installed then 563 00:15:18,800 --> 00:15:21,640 fastener before it was installed then you need about 2,000 psi hydrogen in 564 00:15:21,640 --> 00:15:21,650 you need about 2,000 psi hydrogen in 565 00:15:21,650 --> 00:15:23,800 you need about 2,000 psi hydrogen in order for it to go in the material after 566 00:15:23,800 --> 00:15:23,810 order for it to go in the material after 567 00:15:23,810 --> 00:15:28,090 order for it to go in the material after it's installed so that's not likely to 568 00:15:28,090 --> 00:15:28,100 it's installed so that's not likely to 569 00:15:28,100 --> 00:15:29,920 it's installed so that's not likely to happen but hydrogen embrittlement is 570 00:15:29,920 --> 00:15:29,930 happen but hydrogen embrittlement is 571 00:15:29,930 --> 00:15:34,270 happen but hydrogen embrittlement is always a problem because it depends on 572 00:15:34,270 --> 00:15:34,280 always a problem because it depends on 573 00:15:34,280 --> 00:15:37,620 always a problem because it depends on how good the manufacturer was at making 574 00:15:37,620 --> 00:15:37,630 how good the manufacturer was at making 575 00:15:37,630 --> 00:15:41,790 how good the manufacturer was at making the part so here are some percussions 576 00:15:41,790 --> 00:15:41,800 the part so here are some percussions 577 00:15:41,800 --> 00:15:46,690 the part so here are some percussions use the killed steals coat and plate the 578 00:15:46,690 --> 00:15:46,700 use the killed steals coat and plate the 579 00:15:46,700 --> 00:15:48,910 use the killed steals coat and plate the fasteners bake the hydrogen out within 580 00:15:48,910 --> 00:15:48,920 fasteners bake the hydrogen out within 581 00:15:48,920 --> 00:15:51,640 fasteners bake the hydrogen out within two hours after plating otherwise you 582 00:15:51,640 --> 00:15:51,650 two hours after plating otherwise you 583 00:15:51,650 --> 00:15:52,060 two hours after plating otherwise you can't 584 00:15:52,060 --> 00:15:52,070 can't 585 00:15:52,070 --> 00:15:56,380 can't take it out Taylor the plating bath to 586 00:15:56,380 --> 00:15:56,390 take it out Taylor the plating bath to 587 00:15:56,390 --> 00:16:00,010 take it out Taylor the plating bath to minimize free hydrogen ions and avoid 588 00:16:00,010 --> 00:16:00,020 minimize free hydrogen ions and avoid 589 00:16:00,020 --> 00:16:02,740 minimize free hydrogen ions and avoid the use of alloy steel fasteners above 590 00:16:02,740 --> 00:16:02,750 the use of alloy steel fasteners above 591 00:16:02,750 --> 00:16:05,860 the use of alloy steel fasteners above 190 KSA because the only way you can 592 00:16:05,860 --> 00:16:05,870 190 KSA because the only way you can 593 00:16:05,870 --> 00:16:07,630 190 KSA because the only way you can plate without getting hydrogen 594 00:16:07,630 --> 00:16:07,640 plate without getting hydrogen 595 00:16:07,640 --> 00:16:09,580 plate without getting hydrogen embrittlement is to do it in a vacuum 596 00:16:09,580 --> 00:16:09,590 embrittlement is to do it in a vacuum 597 00:16:09,590 --> 00:16:13,930 embrittlement is to do it in a vacuum atmosphere then use stainless steels 598 00:16:13,930 --> 00:16:13,940 atmosphere then use stainless steels 599 00:16:13,940 --> 00:16:16,030 atmosphere then use stainless steels that are not sensitive to hydrogen 600 00:16:16,030 --> 00:16:16,040 that are not sensitive to hydrogen 601 00:16:16,040 --> 00:16:20,110 that are not sensitive to hydrogen embrittlement and run the tests to see 602 00:16:20,110 --> 00:16:20,120 embrittlement and run the tests to see 603 00:16:20,120 --> 00:16:21,730 embrittlement and run the tests to see if you can find any evidence of any 604 00:16:21,730 --> 00:16:21,740 if you can find any evidence of any 605 00:16:21,740 --> 00:16:28,170 if you can find any evidence of any embrittlement here's one that is 606 00:16:28,170 --> 00:16:28,180 embrittlement here's one that is 607 00:16:28,180 --> 00:16:34,090 embrittlement here's one that is slightly different in your book that had 608 00:16:34,090 --> 00:16:34,100 slightly different in your book that had 609 00:16:34,100 --> 00:16:38,470 slightly different in your book that had had a revised it at the last minute the 610 00:16:38,470 --> 00:16:38,480 had a revised it at the last minute the 611 00:16:38,480 --> 00:16:41,430 had a revised it at the last minute the definition of the graphite here just to 612 00:16:41,430 --> 00:16:41,440 definition of the graphite here just to 613 00:16:41,440 --> 00:16:45,100 definition of the graphite here just to indicate what it is it it's a actually 614 00:16:45,100 --> 00:16:45,110 indicate what it is it it's a actually 615 00:16:45,110 --> 00:16:48,340 indicate what it is it it's a actually to drive dry film carbon lubricant which 616 00:16:48,340 --> 00:16:48,350 to drive dry film carbon lubricant which 617 00:16:48,350 --> 00:16:50,230 to drive dry film carbon lubricant which can cause corrosion when exposed to 618 00:16:50,230 --> 00:16:50,240 can cause corrosion when exposed to 619 00:16:50,240 --> 00:16:56,320 can cause corrosion when exposed to moisture because the on some materials 620 00:16:56,320 --> 00:16:56,330 moisture because the on some materials 621 00:16:56,330 --> 00:17:00,160 moisture because the on some materials and it can cause you problems and I 622 00:17:00,160 --> 00:17:00,170 and it can cause you problems and I 623 00:17:00,170 --> 00:17:04,150 and it can cause you problems and I realize that they put out a la keys or 624 00:17:04,150 --> 00:17:04,160 realize that they put out a la keys or 625 00:17:04,160 --> 00:17:08,949 realize that they put out a la keys or used to put it up which is a graphite in 626 00:17:08,949 --> 00:17:08,959 used to put it up which is a graphite in 627 00:17:08,959 --> 00:17:12,730 used to put it up which is a graphite in oil to use for locks but yet it will 628 00:17:12,730 --> 00:17:12,740 oil to use for locks but yet it will 629 00:17:12,740 --> 00:17:17,110 oil to use for locks but yet it will corrode some types of locks so a guy but 630 00:17:17,110 --> 00:17:17,120 corrode some types of locks so a guy but 631 00:17:17,120 --> 00:17:19,090 corrode some types of locks so a guy but the name of Gilbert gave a course on 632 00:17:19,090 --> 00:17:19,100 the name of Gilbert gave a course on 633 00:17:19,100 --> 00:17:21,130 the name of Gilbert gave a course on corrosion here several years back and he 634 00:17:21,130 --> 00:17:21,140 corrosion here several years back and he 635 00:17:21,140 --> 00:17:23,140 corrosion here several years back and he pointed that out that graphite was a 636 00:17:23,140 --> 00:17:23,150 pointed that out that graphite was a 637 00:17:23,150 --> 00:17:26,050 pointed that out that graphite was a no-no for lubrication of locks for that 638 00:17:26,050 --> 00:17:26,060 no-no for lubrication of locks for that 639 00:17:26,060 --> 00:17:27,520 no-no for lubrication of locks for that reason because it'll actually corrode a 640 00:17:27,520 --> 00:17:27,530 reason because it'll actually corrode a 641 00:17:27,530 --> 00:17:30,400 reason because it'll actually corrode a lot and one of the things then this 642 00:17:30,400 --> 00:17:30,410 lot and one of the things then this 643 00:17:30,410 --> 00:17:31,930 lot and one of the things then this happened to us on one of the turbine 644 00:17:31,930 --> 00:17:31,940 happened to us on one of the turbine 645 00:17:31,940 --> 00:17:36,370 happened to us on one of the turbine engine programs around here is dry 646 00:17:36,370 --> 00:17:36,380 engine programs around here is dry 647 00:17:36,380 --> 00:17:41,740 engine programs around here is dry graphite is an abrasive so if you cook 648 00:17:41,740 --> 00:17:41,750 graphite is an abrasive so if you cook 649 00:17:41,750 --> 00:17:46,360 graphite is an abrasive so if you cook it and dry it out now you have a carbon 650 00:17:46,360 --> 00:17:46,370 it and dry it out now you have a carbon 651 00:17:46,370 --> 00:17:50,380 it and dry it out now you have a carbon powder abrasive which is does a lot more 652 00:17:50,380 --> 00:17:50,390 powder abrasive which is does a lot more 653 00:17:50,390 --> 00:17:52,570 powder abrasive which is does a lot more harm than good and here's something I 654 00:17:52,570 --> 00:17:52,580 harm than good and here's something I 655 00:17:52,580 --> 00:17:54,400 harm than good and here's something I threw in just just for your information 656 00:17:54,400 --> 00:17:54,410 threw in just just for your information 657 00:17:54,410 --> 00:17:57,160 threw in just just for your information I had run into this in a failure course 658 00:17:57,160 --> 00:17:57,170 I had run into this in a failure course 659 00:17:57,170 --> 00:18:00,100 I had run into this in a failure course that I took d zinc tification it's kind 660 00:18:00,100 --> 00:18:00,110 that I took d zinc tification it's kind 661 00:18:00,110 --> 00:18:04,480 that I took d zinc tification it's kind of an odd word but you can actually get 662 00:18:04,480 --> 00:18:04,490 of an odd word but you can actually get 663 00:18:04,490 --> 00:18:06,720 of an odd word but you can actually get in a material that has 664 00:18:06,720 --> 00:18:06,730 in a material that has 665 00:18:06,730 --> 00:18:11,230 in a material that has it's even used for just removal of a 666 00:18:11,230 --> 00:18:11,240 it's even used for just removal of a 667 00:18:11,240 --> 00:18:13,090 it's even used for just removal of a particular element from a material by 668 00:18:13,090 --> 00:18:13,100 particular element from a material by 669 00:18:13,100 --> 00:18:17,500 particular element from a material by corrosion but usually it's the removal 670 00:18:17,500 --> 00:18:17,510 corrosion but usually it's the removal 671 00:18:17,510 --> 00:18:20,160 corrosion but usually it's the removal of zinc from brass by chemical action 672 00:18:20,160 --> 00:18:20,170 of zinc from brass by chemical action 673 00:18:20,170 --> 00:18:24,220 of zinc from brass by chemical action leaves a brittle shell of copper and I 674 00:18:24,220 --> 00:18:24,230 leaves a brittle shell of copper and I 675 00:18:24,230 --> 00:18:26,860 leaves a brittle shell of copper and I saw on the samples the guy had and you 676 00:18:26,860 --> 00:18:26,870 saw on the samples the guy had and you 677 00:18:26,870 --> 00:18:30,690 saw on the samples the guy had and you could compare it to what happens to a 678 00:18:30,690 --> 00:18:30,700 could compare it to what happens to a 679 00:18:30,700 --> 00:18:33,610 could compare it to what happens to a wet piece of wood once the carpenter 680 00:18:33,610 --> 00:18:33,620 wet piece of wood once the carpenter 681 00:18:33,620 --> 00:18:35,920 wet piece of wood once the carpenter ants get done with it it's just a shell 682 00:18:35,920 --> 00:18:35,930 ants get done with it it's just a shell 683 00:18:35,930 --> 00:18:40,810 ants get done with it it's just a shell that you can crush and rather rather 684 00:18:40,810 --> 00:18:40,820 that you can crush and rather rather 685 00:18:40,820 --> 00:18:42,610 that you can crush and rather rather striking to look at a failed piece like 686 00:18:42,610 --> 00:18:42,620 striking to look at a failed piece like 687 00:18:42,620 --> 00:18:45,730 striking to look at a failed piece like that so here's the the galvanic series 688 00:18:45,730 --> 00:18:45,740 that so here's the the galvanic series 689 00:18:45,740 --> 00:18:48,120 that so here's the the galvanic series which I had been talking about earlier 690 00:18:48,120 --> 00:18:48,130 which I had been talking about earlier 691 00:18:48,130 --> 00:18:51,300 which I had been talking about earlier in fact I believe we showed it earlier 692 00:18:51,300 --> 00:18:51,310 in fact I believe we showed it earlier 693 00:18:51,310 --> 00:18:53,830 in fact I believe we showed it earlier that shows the different materials now 694 00:18:53,830 --> 00:18:53,840 that shows the different materials now 695 00:18:53,840 --> 00:18:56,050 that shows the different materials now of course magnesium is right at the top 696 00:18:56,050 --> 00:18:56,060 of course magnesium is right at the top 697 00:18:56,060 --> 00:19:04,060 of course magnesium is right at the top and magnesium is a disaster in a 698 00:19:04,060 --> 00:19:04,070 and magnesium is a disaster in a 699 00:19:04,070 --> 00:19:08,980 and magnesium is a disaster in a corrosive environment in fact this guy 700 00:19:08,980 --> 00:19:08,990 corrosive environment in fact this guy 701 00:19:08,990 --> 00:19:13,950 corrosive environment in fact this guy who taught a course on failure analysis 702 00:19:13,950 --> 00:19:13,960 who taught a course on failure analysis 703 00:19:13,960 --> 00:19:16,690 who taught a course on failure analysis pointed out that when an airplane goes 704 00:19:16,690 --> 00:19:16,700 pointed out that when an airplane goes 705 00:19:16,700 --> 00:19:20,830 pointed out that when an airplane goes down in the ocean one of the ways if it 706 00:19:20,830 --> 00:19:20,840 down in the ocean one of the ways if it 707 00:19:20,840 --> 00:19:23,500 down in the ocean one of the ways if it that they look for it is if it had zinc 708 00:19:23,500 --> 00:19:23,510 that they look for it is if it had zinc 709 00:19:23,510 --> 00:19:26,500 that they look for it is if it had zinc components in it the zinc will decompose 710 00:19:26,500 --> 00:19:26,510 components in it the zinc will decompose 711 00:19:26,510 --> 00:19:28,570 components in it the zinc will decompose so fast in the saltwater that you will 712 00:19:28,570 --> 00:19:28,580 so fast in the saltwater that you will 713 00:19:28,580 --> 00:19:30,700 so fast in the saltwater that you will have bubbles coming up out of the ocean 714 00:19:30,700 --> 00:19:30,710 have bubbles coming up out of the ocean 715 00:19:30,710 --> 00:19:34,560 have bubbles coming up out of the ocean and they can look for it so magnesium 716 00:19:34,560 --> 00:19:34,570 and they can look for it so magnesium 717 00:19:34,570 --> 00:19:37,510 and they can look for it so magnesium I'm a member of the mill handbook five 718 00:19:37,510 --> 00:19:37,520 I'm a member of the mill handbook five 719 00:19:37,520 --> 00:19:40,390 I'm a member of the mill handbook five committee I don't know whether some of 720 00:19:40,390 --> 00:19:40,400 committee I don't know whether some of 721 00:19:40,400 --> 00:19:41,680 committee I don't know whether some of you are familiar with it or not but 722 00:19:41,680 --> 00:19:41,690 you are familiar with it or not but 723 00:19:41,690 --> 00:19:43,240 you are familiar with it or not but anyway it is kind of the Bible the 724 00:19:43,240 --> 00:19:43,250 anyway it is kind of the Bible the 725 00:19:43,250 --> 00:19:47,890 anyway it is kind of the Bible the aerospace materials world and magnesium 726 00:19:47,890 --> 00:19:47,900 aerospace materials world and magnesium 727 00:19:47,900 --> 00:19:53,410 aerospace materials world and magnesium is kinda out of usage by the aircraft 728 00:19:53,410 --> 00:19:53,420 is kinda out of usage by the aircraft 729 00:19:53,420 --> 00:19:55,900 is kinda out of usage by the aircraft manufacturers for this reason because it 730 00:19:55,900 --> 00:19:55,910 manufacturers for this reason because it 731 00:19:55,910 --> 00:19:57,430 manufacturers for this reason because it is so hard to protect it from corrosion 732 00:19:57,430 --> 00:19:57,440 is so hard to protect it from corrosion 733 00:19:57,440 --> 00:20:02,230 is so hard to protect it from corrosion and it's it's not used in any primary 734 00:20:02,230 --> 00:20:02,240 and it's it's not used in any primary 735 00:20:02,240 --> 00:20:04,540 and it's it's not used in any primary structure that I know of on any of the 736 00:20:04,540 --> 00:20:04,550 structure that I know of on any of the 737 00:20:04,550 --> 00:20:08,230 structure that I know of on any of the airplanes okay going on to locking 738 00:20:08,230 --> 00:20:08,240 airplanes okay going on to locking 739 00:20:08,240 --> 00:20:16,060 airplanes okay going on to locking methods in most any application some 740 00:20:16,060 --> 00:20:16,070 methods in most any application some 741 00:20:16,070 --> 00:20:18,610 methods in most any application some type of locking must be used prevent the 742 00:20:18,610 --> 00:20:18,620 type of locking must be used prevent the 743 00:20:18,620 --> 00:20:19,890 type of locking must be used prevent the fastener from loosening 744 00:20:19,890 --> 00:20:19,900 fastener from loosening 745 00:20:19,900 --> 00:20:24,990 fastener from loosening underload and without a locking device 746 00:20:24,990 --> 00:20:25,000 underload and without a locking device 747 00:20:25,000 --> 00:20:27,000 underload and without a locking device of course the only resistance you have 748 00:20:27,000 --> 00:20:27,010 of course the only resistance you have 749 00:20:27,010 --> 00:20:29,610 of course the only resistance you have is just head friction and the nut 750 00:20:29,610 --> 00:20:29,620 is just head friction and the nut 751 00:20:29,620 --> 00:20:34,710 is just head friction and the nut friction which if you are vibrating it 752 00:20:34,710 --> 00:20:34,720 friction which if you are vibrating it 753 00:20:34,720 --> 00:20:37,740 friction which if you are vibrating it very much at all is not enough now find 754 00:20:37,740 --> 00:20:37,750 very much at all is not enough now find 755 00:20:37,750 --> 00:20:39,480 very much at all is not enough now find threads give you slightly better 756 00:20:39,480 --> 00:20:39,490 threads give you slightly better 757 00:20:39,490 --> 00:20:41,640 threads give you slightly better resistance to loosening from vibration 758 00:20:41,640 --> 00:20:41,650 resistance to loosening from vibration 759 00:20:41,650 --> 00:20:44,720 resistance to loosening from vibration than course threads but it's not a lot 760 00:20:44,720 --> 00:20:44,730 than course threads but it's not a lot 761 00:20:44,730 --> 00:20:47,160 than course threads but it's not a lot due to the flatter angle of the threads 762 00:20:47,160 --> 00:20:47,170 due to the flatter angle of the threads 763 00:20:47,170 --> 00:20:50,820 due to the flatter angle of the threads and one of the things that you try to do 764 00:20:50,820 --> 00:20:50,830 and one of the things that you try to do 765 00:20:50,830 --> 00:20:52,860 and one of the things that you try to do and this'll this'll help you once in a 766 00:20:52,860 --> 00:20:52,870 and this'll this'll help you once in a 767 00:20:52,870 --> 00:20:55,260 and this'll this'll help you once in a while is to mount bolts with the heads 768 00:20:55,260 --> 00:20:55,270 while is to mount bolts with the heads 769 00:20:55,270 --> 00:20:59,460 while is to mount bolts with the heads up to lessen the loss of loose bolts 770 00:20:59,460 --> 00:20:59,470 up to lessen the loss of loose bolts 771 00:20:59,470 --> 00:21:01,080 up to lessen the loss of loose bolts because sometimes maybe you'll find 772 00:21:01,080 --> 00:21:01,090 because sometimes maybe you'll find 773 00:21:01,090 --> 00:21:03,000 because sometimes maybe you'll find something on your car that the nuts gone 774 00:21:03,000 --> 00:21:03,010 something on your car that the nuts gone 775 00:21:03,010 --> 00:21:04,350 something on your car that the nuts gone but the bolts still hanging there 776 00:21:04,350 --> 00:21:04,360 but the bolts still hanging there 777 00:21:04,360 --> 00:21:06,150 but the bolts still hanging there flopping back and forth and you can go 778 00:21:06,150 --> 00:21:06,160 flopping back and forth and you can go 779 00:21:06,160 --> 00:21:12,540 flopping back and forth and you can go ahead and put lock that on it now here's 780 00:21:12,540 --> 00:21:12,550 ahead and put lock that on it now here's 781 00:21:12,550 --> 00:21:17,390 ahead and put lock that on it now here's here's one of the most common type of 782 00:21:17,390 --> 00:21:17,400 783 00:21:17,400 --> 00:21:21,380 locking methods is deformed thread and 784 00:21:21,380 --> 00:21:21,390 locking methods is deformed thread and 785 00:21:21,390 --> 00:21:25,710 locking methods is deformed thread and what you do with the nut it's usually on 786 00:21:25,710 --> 00:21:25,720 what you do with the nut it's usually on 787 00:21:25,720 --> 00:21:30,270 what you do with the nut it's usually on the net after you have formed it the 788 00:21:30,270 --> 00:21:30,280 the net after you have formed it the 789 00:21:30,280 --> 00:21:32,730 the net after you have formed it the last operation you actually hit it from 790 00:21:32,730 --> 00:21:32,740 last operation you actually hit it from 791 00:21:32,740 --> 00:21:38,580 last operation you actually hit it from two sides and make it slightly oval then 792 00:21:38,580 --> 00:21:38,590 two sides and make it slightly oval then 793 00:21:38,590 --> 00:21:41,580 two sides and make it slightly oval then when you put it on and this this hits 794 00:21:41,580 --> 00:21:41,590 when you put it on and this this hits 795 00:21:41,590 --> 00:21:43,560 when you put it on and this this hits got to be controlled to because 796 00:21:43,560 --> 00:21:43,570 got to be controlled to because 797 00:21:43,570 --> 00:21:48,230 got to be controlled to because otherwise you can be in heap of trouble 798 00:21:48,230 --> 00:21:48,240 otherwise you can be in heap of trouble 799 00:21:48,240 --> 00:21:53,130 otherwise you can be in heap of trouble it will kind of go back to circular 800 00:21:53,130 --> 00:21:53,140 it will kind of go back to circular 801 00:21:53,140 --> 00:21:55,860 it will kind of go back to circular again so let's see initially here it is 802 00:21:55,860 --> 00:21:55,870 again so let's see initially here it is 803 00:21:55,870 --> 00:21:58,350 again so let's see initially here it is oval then when you put the thing on it 804 00:21:58,350 --> 00:21:58,360 oval then when you put the thing on it 805 00:21:58,360 --> 00:22:01,230 oval then when you put the thing on it goes the circular it will actually be 806 00:22:01,230 --> 00:22:01,240 goes the circular it will actually be 807 00:22:01,240 --> 00:22:03,540 goes the circular it will actually be for them enough and of course when it 808 00:22:03,540 --> 00:22:03,550 for them enough and of course when it 809 00:22:03,550 --> 00:22:06,650 for them enough and of course when it does that the threads will lock up on 810 00:22:06,650 --> 00:22:06,660 does that the threads will lock up on 811 00:22:06,660 --> 00:22:10,590 does that the threads will lock up on the bolt then when you take it off it 812 00:22:10,590 --> 00:22:10,600 the bolt then when you take it off it 813 00:22:10,600 --> 00:22:14,250 the bolt then when you take it off it will go back to oval again so you can 814 00:22:14,250 --> 00:22:14,260 will go back to oval again so you can 815 00:22:14,260 --> 00:22:18,210 will go back to oval again so you can use this one all around ten times before 816 00:22:18,210 --> 00:22:18,220 use this one all around ten times before 817 00:22:18,220 --> 00:22:20,430 use this one all around ten times before it loses its locking capability because 818 00:22:20,430 --> 00:22:20,440 it loses its locking capability because 819 00:22:20,440 --> 00:22:22,290 it loses its locking capability because eventually putting it on and off you're 820 00:22:22,290 --> 00:22:22,300 eventually putting it on and off you're 821 00:22:22,300 --> 00:22:26,690 eventually putting it on and off you're going to yield it back to the circular 822 00:22:26,690 --> 00:22:26,700 going to yield it back to the circular 823 00:22:26,700 --> 00:22:30,210 going to yield it back to the circular condition and it will no longer lock but 824 00:22:30,210 --> 00:22:30,220 condition and it will no longer lock but 825 00:22:30,220 --> 00:22:32,250 condition and it will no longer lock but that's one of the good ones and you can 826 00:22:32,250 --> 00:22:32,260 that's one of the good ones and you can 827 00:22:32,260 --> 00:22:33,180 that's one of the good ones and you can buy 828 00:22:33,180 --> 00:22:33,190 buy 829 00:22:33,190 --> 00:22:36,540 buy the forum thread lock nut set your 830 00:22:36,540 --> 00:22:36,550 the forum thread lock nut set your 831 00:22:36,550 --> 00:22:43,350 the forum thread lock nut set your hardware store now here is the locking 832 00:22:43,350 --> 00:22:43,360 hardware store now here is the locking 833 00:22:43,360 --> 00:22:46,590 hardware store now here is the locking collar tight and although I didn't call 834 00:22:46,590 --> 00:22:46,600 collar tight and although I didn't call 835 00:22:46,600 --> 00:22:49,470 collar tight and although I didn't call it out your elastic stop net is one of 836 00:22:49,470 --> 00:22:49,480 it out your elastic stop net is one of 837 00:22:49,480 --> 00:22:51,870 it out your elastic stop net is one of the biggest manufacturers of these what 838 00:22:51,870 --> 00:22:51,880 the biggest manufacturers of these what 839 00:22:51,880 --> 00:22:54,990 the biggest manufacturers of these what you have is you have a fiber or nylon 840 00:22:54,990 --> 00:22:55,000 you have is you have a fiber or nylon 841 00:22:55,000 --> 00:22:59,730 you have is you have a fiber or nylon collar here in the top of it the caller 842 00:22:59,730 --> 00:22:59,740 collar here in the top of it the caller 843 00:22:59,740 --> 00:23:04,080 collar here in the top of it the caller has a smaller diameter then the the bolt 844 00:23:04,080 --> 00:23:04,090 has a smaller diameter then the the bolt 845 00:23:04,090 --> 00:23:07,020 has a smaller diameter then the the bolt thread so when you run the bolt in it 846 00:23:07,020 --> 00:23:07,030 thread so when you run the bolt in it 847 00:23:07,030 --> 00:23:10,890 thread so when you run the bolt in it will interfere on that collar and it'll 848 00:23:10,890 --> 00:23:10,900 will interfere on that collar and it'll 849 00:23:10,900 --> 00:23:12,990 will interfere on that collar and it'll also provide a little bit of sealing if 850 00:23:12,990 --> 00:23:13,000 also provide a little bit of sealing if 851 00:23:13,000 --> 00:23:15,720 also provide a little bit of sealing if you kind of seal from getting water in 852 00:23:15,720 --> 00:23:15,730 you kind of seal from getting water in 853 00:23:15,730 --> 00:23:17,280 you kind of seal from getting water in there to give you that much ceiling 854 00:23:17,280 --> 00:23:17,290 there to give you that much ceiling 855 00:23:17,290 --> 00:23:18,990 there to give you that much ceiling although it's not for pressure or 856 00:23:18,990 --> 00:23:19,000 although it's not for pressure or 857 00:23:19,000 --> 00:23:21,060 although it's not for pressure or anything like that but the only problem 858 00:23:21,060 --> 00:23:21,070 anything like that but the only problem 859 00:23:21,070 --> 00:23:23,280 anything like that but the only problem is this collar area is usually only good 860 00:23:23,280 --> 00:23:23,290 is this collar area is usually only good 861 00:23:23,290 --> 00:23:26,070 is this collar area is usually only good for about 250 degrees to where it will 862 00:23:26,070 --> 00:23:26,080 for about 250 degrees to where it will 863 00:23:26,080 --> 00:23:27,930 for about 250 degrees to where it will start softening up to where to become 864 00:23:27,930 --> 00:23:27,940 start softening up to where to become 865 00:23:27,940 --> 00:23:32,640 start softening up to where to become ineffective now here's the split beam 866 00:23:32,640 --> 00:23:32,650 ineffective now here's the split beam 867 00:23:32,650 --> 00:23:37,080 ineffective now here's the split beam lock nut this is one that works quite 868 00:23:37,080 --> 00:23:37,090 lock nut this is one that works quite 869 00:23:37,090 --> 00:23:40,260 lock nut this is one that works quite well and what you have you have a 870 00:23:40,260 --> 00:23:40,270 well and what you have you have a 871 00:23:40,270 --> 00:23:43,590 well and what you have you have a smaller diameter at the top of it and 872 00:23:43,590 --> 00:23:43,600 smaller diameter at the top of it and 873 00:23:43,600 --> 00:23:48,600 smaller diameter at the top of it and its salt cut so that when you put it on 874 00:23:48,600 --> 00:23:48,610 its salt cut so that when you put it on 875 00:23:48,610 --> 00:23:51,030 its salt cut so that when you put it on it'll spin freely till it gets up to 876 00:23:51,030 --> 00:23:51,040 it'll spin freely till it gets up to 877 00:23:51,040 --> 00:23:55,500 it'll spin freely till it gets up to that area then as you tighten it up the 878 00:23:55,500 --> 00:23:55,510 that area then as you tighten it up the 879 00:23:55,510 --> 00:23:58,880 that area then as you tighten it up the beams if you will these six beams on it 880 00:23:58,880 --> 00:23:58,890 beams if you will these six beams on it 881 00:23:58,890 --> 00:24:02,310 beams if you will these six beams on it have to deflect outward in order for the 882 00:24:02,310 --> 00:24:02,320 have to deflect outward in order for the 883 00:24:02,320 --> 00:24:05,100 have to deflect outward in order for the bolt to go through so once again this 884 00:24:05,100 --> 00:24:05,110 bolt to go through so once again this 885 00:24:05,110 --> 00:24:07,410 bolt to go through so once again this gives you a pretty heavy friction load 886 00:24:07,410 --> 00:24:07,420 gives you a pretty heavy friction load 887 00:24:07,420 --> 00:24:10,170 gives you a pretty heavy friction load on the threads and will lock it in place 888 00:24:10,170 --> 00:24:10,180 on the threads and will lock it in place 889 00:24:10,180 --> 00:24:13,830 on the threads and will lock it in place I had a personal experience with the one 890 00:24:13,830 --> 00:24:13,840 I had a personal experience with the one 891 00:24:13,840 --> 00:24:15,990 I had a personal experience with the one of these on a car that I had that the 892 00:24:15,990 --> 00:24:16,000 of these on a car that I had that the 893 00:24:16,000 --> 00:24:17,490 of these on a car that I had that the shock absorbers didn't want to stay on 894 00:24:17,490 --> 00:24:17,500 shock absorbers didn't want to stay on 895 00:24:17,500 --> 00:24:20,340 shock absorbers didn't want to stay on it and I put these split beam lock nuts 896 00:24:20,340 --> 00:24:20,350 it and I put these split beam lock nuts 897 00:24:20,350 --> 00:24:24,420 it and I put these split beam lock nuts on it and that held versus the the jam 898 00:24:24,420 --> 00:24:24,430 on it and that held versus the the jam 899 00:24:24,430 --> 00:24:27,600 on it and that held versus the the jam nut to which I'll cover later now here's 900 00:24:27,600 --> 00:24:27,610 nut to which I'll cover later now here's 901 00:24:27,610 --> 00:24:30,780 nut to which I'll cover later now here's a nighlok pellet nighlok is the biggest 902 00:24:30,780 --> 00:24:30,790 a nighlok pellet nighlok is the biggest 903 00:24:30,790 --> 00:24:32,850 a nighlok pellet nighlok is the biggest manufacturer of this type of thing 904 00:24:32,850 --> 00:24:32,860 manufacturer of this type of thing 905 00:24:32,860 --> 00:24:37,110 manufacturer of this type of thing although it's even covered by a milspec 906 00:24:37,110 --> 00:24:37,120 although it's even covered by a milspec 907 00:24:37,120 --> 00:24:39,450 although it's even covered by a milspec so there's a lot of people in on the act 908 00:24:39,450 --> 00:24:39,460 so there's a lot of people in on the act 909 00:24:39,460 --> 00:24:41,370 so there's a lot of people in on the act on making it this way but what do you do 910 00:24:41,370 --> 00:24:41,380 on making it this way but what do you do 911 00:24:41,380 --> 00:24:43,530 on making it this way but what do you do is you you cut a little hole in the 912 00:24:43,530 --> 00:24:43,540 is you you cut a little hole in the 913 00:24:43,540 --> 00:24:47,010 is you you cut a little hole in the thread and stick a nighlok plug in it 914 00:24:47,010 --> 00:24:47,020 thread and stick a nighlok plug in it 915 00:24:47,020 --> 00:24:50,760 thread and stick a nighlok plug in it and this plug sticks up past the thread 916 00:24:50,760 --> 00:24:50,770 and this plug sticks up past the thread 917 00:24:50,770 --> 00:24:53,940 and this plug sticks up past the thread so when you when you put it on the nylon 918 00:24:53,940 --> 00:24:53,950 so when you when you put it on the nylon 919 00:24:53,950 --> 00:24:58,350 so when you when you put it on the nylon will bind up in the threads and cause it 920 00:24:58,350 --> 00:24:58,360 will bind up in the threads and cause it 921 00:24:58,360 --> 00:25:02,160 will bind up in the threads and cause it to lock this one is a fairly good cheap 922 00:25:02,160 --> 00:25:02,170 to lock this one is a fairly good cheap 923 00:25:02,170 --> 00:25:05,780 to lock this one is a fairly good cheap way of locking stuff using on a bicycle 924 00:25:05,780 --> 00:25:05,790 way of locking stuff using on a bicycle 925 00:25:05,790 --> 00:25:07,920 way of locking stuff using on a bicycle lawnmower or something like that it'll 926 00:25:07,920 --> 00:25:07,930 lawnmower or something like that it'll 927 00:25:07,930 --> 00:25:12,360 lawnmower or something like that it'll hold up but once again the temperature 928 00:25:12,360 --> 00:25:12,370 hold up but once again the temperature 929 00:25:12,370 --> 00:25:14,250 hold up but once again the temperature range on it is kind of low because nylon 930 00:25:14,250 --> 00:25:14,260 range on it is kind of low because nylon 931 00:25:14,260 --> 00:25:18,090 range on it is kind of low because nylon as starts getting soft about 250 degrees 932 00:25:18,090 --> 00:25:18,100 as starts getting soft about 250 degrees 933 00:25:18,100 --> 00:25:20,820 as starts getting soft about 250 degrees and of course the threads will chew it 934 00:25:20,820 --> 00:25:20,830 and of course the threads will chew it 935 00:25:20,830 --> 00:25:24,120 and of course the threads will chew it up so you can't put the thing on take it 936 00:25:24,120 --> 00:25:24,130 up so you can't put the thing on take it 937 00:25:24,130 --> 00:25:25,920 up so you can't put the thing on take it off very many times without run into 938 00:25:25,920 --> 00:25:25,930 off very many times without run into 939 00:25:25,930 --> 00:25:32,430 off very many times without run into trouble now here's luck tight which we 940 00:25:32,430 --> 00:25:32,440 trouble now here's luck tight which we 941 00:25:32,440 --> 00:25:33,780 trouble now here's luck tight which we use around here all the time that's 942 00:25:33,780 --> 00:25:33,790 use around here all the time that's 943 00:25:33,790 --> 00:25:35,900 use around here all the time that's actually a trade name but different 944 00:25:35,900 --> 00:25:35,910 actually a trade name but different 945 00:25:35,910 --> 00:25:41,030 actually a trade name but different people make this it's actually a a one 946 00:25:41,030 --> 00:25:41,040 people make this it's actually a a one 947 00:25:41,040 --> 00:25:44,040 people make this it's actually a a one one component type adhesive that you 948 00:25:44,040 --> 00:25:44,050 one component type adhesive that you 949 00:25:44,050 --> 00:25:46,640 one component type adhesive that you just smear on the fastener before you 950 00:25:46,640 --> 00:25:46,650 just smear on the fastener before you 951 00:25:46,650 --> 00:25:50,100 just smear on the fastener before you assemble it and it's made in different 952 00:25:50,100 --> 00:25:50,110 assemble it and it's made in different 953 00:25:50,110 --> 00:25:53,400 assemble it and it's made in different grades so that if you want to remove the 954 00:25:53,400 --> 00:25:53,410 grades so that if you want to remove the 955 00:25:53,410 --> 00:25:55,830 grades so that if you want to remove the fastener you use the volesse sticky tape 956 00:25:55,830 --> 00:25:55,840 fastener you use the volesse sticky tape 957 00:25:55,840 --> 00:25:58,640 fastener you use the volesse sticky tape like an in Lafayette I think 242 is 958 00:25:58,640 --> 00:25:58,650 like an in Lafayette I think 242 is 959 00:25:58,650 --> 00:26:01,890 like an in Lafayette I think 242 is removable and 271 as the tamper-proof 960 00:26:01,890 --> 00:26:01,900 removable and 271 as the tamper-proof 961 00:26:01,900 --> 00:26:05,040 removable and 271 as the tamper-proof fasteners and there's another one in but 962 00:26:05,040 --> 00:26:05,050 fasteners and there's another one in but 963 00:26:05,050 --> 00:26:06,930 fasteners and there's another one in but to another one or two in between there 964 00:26:06,930 --> 00:26:06,940 to another one or two in between there 965 00:26:06,940 --> 00:26:08,940 to another one or two in between there four bolts that you just want to make 966 00:26:08,940 --> 00:26:08,950 four bolts that you just want to make 967 00:26:08,950 --> 00:26:12,480 four bolts that you just want to make difficult to get off but some of the 968 00:26:12,480 --> 00:26:12,490 difficult to get off but some of the 969 00:26:12,490 --> 00:26:14,760 difficult to get off but some of the manufacturers other manufacturers of 970 00:26:14,760 --> 00:26:14,770 manufacturers other manufacturers of 971 00:26:14,770 --> 00:26:17,220 manufacturers other manufacturers of this are Bostick in the industry's 972 00:26:17,220 --> 00:26:17,230 this are Bostick in the industry's 973 00:26:17,230 --> 00:26:20,570 this are Bostick in the industry's nighlok 3m velcro and perma bond and 974 00:26:20,570 --> 00:26:20,580 nighlok 3m velcro and perma bond and 975 00:26:20,580 --> 00:26:23,130 nighlok 3m velcro and perma bond and lock tight is good up to about 400 976 00:26:23,130 --> 00:26:23,140 lock tight is good up to about 400 977 00:26:23,140 --> 00:26:31,740 lock tight is good up to about 400 degrees now a poxy ribbon this is used a 978 00:26:31,740 --> 00:26:31,750 degrees now a poxy ribbon this is used a 979 00:26:31,750 --> 00:26:34,980 degrees now a poxy ribbon this is used a lot on bolts you get them and they have 980 00:26:34,980 --> 00:26:34,990 lot on bolts you get them and they have 981 00:26:34,990 --> 00:26:38,280 lot on bolts you get them and they have to to ribbons of epoxy so that you have 982 00:26:38,280 --> 00:26:38,290 to to ribbons of epoxy so that you have 983 00:26:38,290 --> 00:26:40,860 to to ribbons of epoxy so that you have the main one and then you have the 984 00:26:40,860 --> 00:26:40,870 the main one and then you have the 985 00:26:40,870 --> 00:26:43,830 the main one and then you have the hardener that goes with it and this way 986 00:26:43,830 --> 00:26:43,840 hardener that goes with it and this way 987 00:26:43,840 --> 00:26:46,520 hardener that goes with it and this way you can store them it has a shelf life 988 00:26:46,520 --> 00:26:46,530 you can store them it has a shelf life 989 00:26:46,530 --> 00:26:51,480 you can store them it has a shelf life at least that you can keep them for I 990 00:26:51,480 --> 00:26:51,490 at least that you can keep them for I 991 00:26:51,490 --> 00:26:54,600 at least that you can keep them for I think up the years like that and the 992 00:26:54,600 --> 00:26:54,610 think up the years like that and the 993 00:26:54,610 --> 00:26:59,010 think up the years like that and the epoxy is mixed when you install it so it 994 00:26:59,010 --> 00:26:59,020 epoxy is mixed when you install it so it 995 00:26:59,020 --> 00:27:00,690 epoxy is mixed when you install it so it will combine in 996 00:27:00,690 --> 00:27:00,700 will combine in 997 00:27:00,700 --> 00:27:03,180 will combine in a hardon to hold the fastener in place 998 00:27:03,180 --> 00:27:03,190 a hardon to hold the fastener in place 999 00:27:03,190 --> 00:27:04,710 a hardon to hold the fastener in place now of course this type once you would 1000 00:27:04,710 --> 00:27:04,720 now of course this type once you would 1001 00:27:04,720 --> 00:27:08,340 now of course this type once you would remove it it would have to be replaced 1002 00:27:08,340 --> 00:27:08,350 remove it it would have to be replaced 1003 00:27:08,350 --> 00:27:10,110 remove it it would have to be replaced because it you destroyed the seal 1004 00:27:10,110 --> 00:27:10,120 because it you destroyed the seal 1005 00:27:10,120 --> 00:27:12,450 because it you destroyed the seal because it's a one-time type thing and 1006 00:27:12,450 --> 00:27:12,460 because it's a one-time type thing and 1007 00:27:12,460 --> 00:27:14,970 because it's a one-time type thing and the maximum operating temperature on 1008 00:27:14,970 --> 00:27:14,980 the maximum operating temperature on 1009 00:27:14,980 --> 00:27:21,870 the maximum operating temperature on these is also about 400 degrees here is 1010 00:27:21,870 --> 00:27:21,880 these is also about 400 degrees here is 1011 00:27:21,880 --> 00:27:24,480 these is also about 400 degrees here is another type of thread as a special 1012 00:27:24,480 --> 00:27:24,490 another type of thread as a special 1013 00:27:24,490 --> 00:27:26,970 another type of thread as a special thread spiral lock I think Detroit 1014 00:27:26,970 --> 00:27:26,980 thread spiral lock I think Detroit 1015 00:27:26,980 --> 00:27:29,820 thread spiral lock I think Detroit tappan dies the holder the patent on 1016 00:27:29,820 --> 00:27:29,830 tappan dies the holder the patent on 1017 00:27:29,830 --> 00:27:32,610 tappan dies the holder the patent on this one and this is a cross section 1018 00:27:32,610 --> 00:27:32,620 this one and this is a cross section 1019 00:27:32,620 --> 00:27:37,980 this one and this is a cross section here of a kept thread and a fastener now 1020 00:27:37,980 --> 00:27:37,990 here of a kept thread and a fastener now 1021 00:27:37,990 --> 00:27:41,910 here of a kept thread and a fastener now the problem with this when you install 1022 00:27:41,910 --> 00:27:41,920 the problem with this when you install 1023 00:27:41,920 --> 00:27:45,420 the problem with this when you install it is you have to have spiral locks tap 1024 00:27:45,420 --> 00:27:45,430 it is you have to have spiral locks tap 1025 00:27:45,430 --> 00:27:47,700 it is you have to have spiral locks tap because this is an oddball see the 1026 00:27:47,700 --> 00:27:47,710 because this is an oddball see the 1027 00:27:47,710 --> 00:27:51,290 because this is an oddball see the thread the tap cold is not fit the 1028 00:27:51,290 --> 00:27:51,300 thread the tap cold is not fit the 1029 00:27:51,300 --> 00:27:54,150 thread the tap cold is not fit the thread and you get your locking action 1030 00:27:54,150 --> 00:27:54,160 thread and you get your locking action 1031 00:27:54,160 --> 00:27:58,860 thread and you get your locking action by actually wedging the ramp of the 1032 00:27:58,860 --> 00:27:58,870 by actually wedging the ramp of the 1033 00:27:58,870 --> 00:28:04,530 by actually wedging the ramp of the thread up against the oddball tape tap 1034 00:28:04,530 --> 00:28:04,540 thread up against the oddball tape tap 1035 00:28:04,540 --> 00:28:08,160 thread up against the oddball tape tap and but you can distribute over several 1036 00:28:08,160 --> 00:28:08,170 and but you can distribute over several 1037 00:28:08,170 --> 00:28:11,700 and but you can distribute over several threads so it offers better locking 1038 00:28:11,700 --> 00:28:11,710 threads so it offers better locking 1039 00:28:11,710 --> 00:28:14,850 threads so it offers better locking capability than ordinary thread would 1040 00:28:14,850 --> 00:28:14,860 capability than ordinary thread would 1041 00:28:14,860 --> 00:28:18,450 capability than ordinary thread would and some people have used it and run 1042 00:28:18,450 --> 00:28:18,460 and some people have used it and run 1043 00:28:18,460 --> 00:28:20,430 and some people have used it and run vibration tests and it holds up fairly 1044 00:28:20,430 --> 00:28:20,440 vibration tests and it holds up fairly 1045 00:28:20,440 --> 00:28:23,520 vibration tests and it holds up fairly well but of course the the disadvantage 1046 00:28:23,520 --> 00:28:23,530 well but of course the the disadvantage 1047 00:28:23,530 --> 00:28:28,410 well but of course the the disadvantage is that you can't you have to get their 1048 00:28:28,410 --> 00:28:28,420 is that you can't you have to get their 1049 00:28:28,420 --> 00:28:31,850 is that you can't you have to get their tap to tap the whole initially and and 1050 00:28:31,850 --> 00:28:31,860 tap to tap the whole initially and and 1051 00:28:31,860 --> 00:28:34,620 tap to tap the whole initially and and so that creates a problem sometimes for 1052 00:28:34,620 --> 00:28:34,630 so that creates a problem sometimes for 1053 00:28:34,630 --> 00:28:38,070 so that creates a problem sometimes for people on universal type of sembly on 1054 00:28:38,070 --> 00:28:38,080 people on universal type of sembly on 1055 00:28:38,080 --> 00:28:42,210 people on universal type of sembly on the direct interfering thread in this 1056 00:28:42,210 --> 00:28:42,220 the direct interfering thread in this 1057 00:28:42,220 --> 00:28:45,960 the direct interfering thread in this case you just have a fastener that is 1058 00:28:45,960 --> 00:28:45,970 case you just have a fastener that is 1059 00:28:45,970 --> 00:28:51,690 case you just have a fastener that is made deliberately with an oversized root 1060 00:28:51,690 --> 00:28:51,700 made deliberately with an oversized root 1061 00:28:51,700 --> 00:28:56,520 made deliberately with an oversized root diameter to give a slight interference 1062 00:28:56,520 --> 00:28:56,530 diameter to give a slight interference 1063 00:28:56,530 --> 00:29:00,210 diameter to give a slight interference fit to lock now some studs that you have 1064 00:29:00,210 --> 00:29:00,220 fit to lock now some studs that you have 1065 00:29:00,220 --> 00:29:02,610 fit to lock now some studs that you have where you have a stud that is installed 1066 00:29:02,610 --> 00:29:02,620 where you have a stud that is installed 1067 00:29:02,620 --> 00:29:04,470 where you have a stud that is installed in something and you want to leave it in 1068 00:29:04,470 --> 00:29:04,480 in something and you want to leave it in 1069 00:29:04,480 --> 00:29:08,070 in something and you want to leave it in place you use this type of thread so 1070 00:29:08,070 --> 00:29:08,080 place you use this type of thread so 1071 00:29:08,080 --> 00:29:11,280 place you use this type of thread so that it will not come out when you take 1072 00:29:11,280 --> 00:29:11,290 that it will not come out when you take 1073 00:29:11,290 --> 00:29:13,860 that it will not come out when you take the nut off the other end the tapered 1074 00:29:13,860 --> 00:29:13,870 the nut off the other end the tapered 1075 00:29:13,870 --> 00:29:14,580 the nut off the other end the tapered thread 1076 00:29:14,580 --> 00:29:14,590 thread 1077 00:29:14,590 --> 00:29:16,409 thread is kind of a variation of this and what 1078 00:29:16,409 --> 00:29:16,419 is kind of a variation of this and what 1079 00:29:16,419 --> 00:29:18,180 is kind of a variation of this and what you actually tapert this is a smaller 1080 00:29:18,180 --> 00:29:18,190 you actually tapert this is a smaller 1081 00:29:18,190 --> 00:29:22,250 you actually tapert this is a smaller diameter up in here and then when you 1082 00:29:22,250 --> 00:29:22,260 diameter up in here and then when you 1083 00:29:22,260 --> 00:29:26,460 diameter up in here and then when you put it together it has to push the 1084 00:29:26,460 --> 00:29:26,470 put it together it has to push the 1085 00:29:26,470 --> 00:29:30,840 put it together it has to push the threads out here and that gives you a 1086 00:29:30,840 --> 00:29:30,850 threads out here and that gives you a 1087 00:29:30,850 --> 00:29:39,930 threads out here and that gives you a locking force on it now here's one that 1088 00:29:39,930 --> 00:29:39,940 locking force on it now here's one that 1089 00:29:39,940 --> 00:29:42,659 locking force on it now here's one that we covered in the drafting room manual 1090 00:29:42,659 --> 00:29:42,669 we covered in the drafting room manual 1091 00:29:42,669 --> 00:29:45,659 we covered in the drafting room manual stuff run Roman check that we we fought 1092 00:29:45,659 --> 00:29:45,669 stuff run Roman check that we we fought 1093 00:29:45,669 --> 00:29:47,610 stuff run Roman check that we we fought semantics on that one a lot whether it's 1094 00:29:47,610 --> 00:29:47,620 semantics on that one a lot whether it's 1095 00:29:47,620 --> 00:29:50,810 semantics on that one a lot whether it's a castle nut or a castellated nut so 1096 00:29:50,810 --> 00:29:50,820 a castle nut or a castellated nut so 1097 00:29:50,820 --> 00:29:53,519 a castle nut or a castellated nut so since I wrote this I put my preferences 1098 00:29:53,519 --> 00:29:53,529 since I wrote this I put my preferences 1099 00:29:53,529 --> 00:29:57,630 since I wrote this I put my preferences castellated nut with a cotter pin this 1100 00:29:57,630 --> 00:29:57,640 castellated nut with a cotter pin this 1101 00:29:57,640 --> 00:30:03,600 castellated nut with a cotter pin this is used a lot for installing bearings 1102 00:30:03,600 --> 00:30:03,610 is used a lot for installing bearings 1103 00:30:03,610 --> 00:30:05,399 is used a lot for installing bearings and things like that where you don't 1104 00:30:05,399 --> 00:30:05,409 and things like that where you don't 1105 00:30:05,409 --> 00:30:07,710 and things like that where you don't want to tighten it very tight but you 1106 00:30:07,710 --> 00:30:07,720 want to tighten it very tight but you 1107 00:30:07,720 --> 00:30:10,100 want to tighten it very tight but you want it to stay put once you tighten it 1108 00:30:10,100 --> 00:30:10,110 want it to stay put once you tighten it 1109 00:30:10,110 --> 00:30:16,950 want it to stay put once you tighten it so you can take the nut up then to the 1110 00:30:16,950 --> 00:30:16,960 so you can take the nut up then to the 1111 00:30:16,960 --> 00:30:20,130 so you can take the nut up then to the to the Turk you want then back it off or 1112 00:30:20,130 --> 00:30:20,140 to the Turk you want then back it off or 1113 00:30:20,140 --> 00:30:22,320 to the Turk you want then back it off or taking it to the next next spot on it to 1114 00:30:22,320 --> 00:30:22,330 taking it to the next next spot on it to 1115 00:30:22,330 --> 00:30:24,539 taking it to the next next spot on it to get you a slot because you only have a 1116 00:30:24,539 --> 00:30:24,549 get you a slot because you only have a 1117 00:30:24,549 --> 00:30:26,490 get you a slot because you only have a single hole drilled in the end of the 1118 00:30:26,490 --> 00:30:26,500 single hole drilled in the end of the 1119 00:30:26,500 --> 00:30:28,500 single hole drilled in the end of the fastener so you line up one of these 1120 00:30:28,500 --> 00:30:28,510 fastener so you line up one of these 1121 00:30:28,510 --> 00:30:31,409 fastener so you line up one of these with that hole then put a cotter 1122 00:30:31,409 --> 00:30:31,419 with that hole then put a cotter 1123 00:30:31,419 --> 00:30:35,090 with that hole then put a cotter pin in it and it will hold it in place 1124 00:30:35,090 --> 00:30:35,100 pin in it and it will hold it in place 1125 00:30:35,100 --> 00:30:40,700 pin in it and it will hold it in place at the exact spot that you said it and 1126 00:30:40,700 --> 00:30:40,710 at the exact spot that you said it and 1127 00:30:40,710 --> 00:30:45,240 at the exact spot that you said it and this way when your for instance a lot of 1128 00:30:45,240 --> 00:30:45,250 this way when your for instance a lot of 1129 00:30:45,250 --> 00:30:47,100 this way when your for instance a lot of the cars are made this way there's 1130 00:30:47,100 --> 00:30:47,110 the cars are made this way there's 1131 00:30:47,110 --> 00:30:48,720 the cars are made this way there's another way that would be my next slide 1132 00:30:48,720 --> 00:30:48,730 another way that would be my next slide 1133 00:30:48,730 --> 00:30:52,980 another way that would be my next slide I think but on wheel bearing when you 1134 00:30:52,980 --> 00:30:52,990 I think but on wheel bearing when you 1135 00:30:52,990 --> 00:30:54,810 I think but on wheel bearing when you tighten it up usually you tighten it up 1136 00:30:54,810 --> 00:30:54,820 tighten it up usually you tighten it up 1137 00:30:54,820 --> 00:30:57,539 tighten it up usually you tighten it up tight seek the bearings then back it off 1138 00:30:57,539 --> 00:30:57,549 tight seek the bearings then back it off 1139 00:30:57,549 --> 00:31:00,630 tight seek the bearings then back it off enough to let it spin so the nut is a 1140 00:31:00,630 --> 00:31:00,640 enough to let it spin so the nut is a 1141 00:31:00,640 --> 00:31:04,590 enough to let it spin so the nut is a little more than finger tight now here's 1142 00:31:04,590 --> 00:31:04,600 little more than finger tight now here's 1143 00:31:04,600 --> 00:31:06,299 little more than finger tight now here's a nut here's another one that is used 1144 00:31:06,299 --> 00:31:06,309 a nut here's another one that is used 1145 00:31:06,309 --> 00:31:09,269 a nut here's another one that is used for the same reason evidently this is 1146 00:31:09,269 --> 00:31:09,279 for the same reason evidently this is 1147 00:31:09,279 --> 00:31:12,360 for the same reason evidently this is cheaper because you're doing the same 1148 00:31:12,360 --> 00:31:12,370 cheaper because you're doing the same 1149 00:31:12,370 --> 00:31:16,440 cheaper because you're doing the same thing with a regular nut then you're 1150 00:31:16,440 --> 00:31:16,450 thing with a regular nut then you're 1151 00:31:16,450 --> 00:31:18,690 thing with a regular nut then you're taking this nut cap which is a sheet 1152 00:31:18,690 --> 00:31:18,700 taking this nut cap which is a sheet 1153 00:31:18,700 --> 00:31:21,870 taking this nut cap which is a sheet metal stamp sheet metal piece but it has 1154 00:31:21,870 --> 00:31:21,880 metal stamp sheet metal piece but it has 1155 00:31:21,880 --> 00:31:24,450 metal stamp sheet metal piece but it has the serrations here with the slot senate 1156 00:31:24,450 --> 00:31:24,460 the serrations here with the slot senate 1157 00:31:24,460 --> 00:31:26,450 the serrations here with the slot senate that you can put the cotter pin in 1158 00:31:26,450 --> 00:31:26,460 that you can put the cotter pin in 1159 00:31:26,460 --> 00:31:31,070 that you can put the cotter pin in so you Turk the nut to the spot you want 1160 00:31:31,070 --> 00:31:31,080 so you Turk the nut to the spot you want 1161 00:31:31,080 --> 00:31:35,600 so you Turk the nut to the spot you want it then slip this thing over it then put 1162 00:31:35,600 --> 00:31:35,610 it then slip this thing over it then put 1163 00:31:35,610 --> 00:31:39,340 it then slip this thing over it then put the cotter pin through the hole in the 1164 00:31:39,340 --> 00:31:39,350 the cotter pin through the hole in the 1165 00:31:39,350 --> 00:31:43,340 the cotter pin through the hole in the axle or shaft whatever it is and fasten 1166 00:31:43,340 --> 00:31:43,350 axle or shaft whatever it is and fasten 1167 00:31:43,350 --> 00:31:44,930 axle or shaft whatever it is and fasten it the same way as we did on the other 1168 00:31:44,930 --> 00:31:44,940 it the same way as we did on the other 1169 00:31:44,940 --> 00:31:46,580 it the same way as we did on the other one and of course the reason that grease 1170 00:31:46,580 --> 00:31:46,590 one and of course the reason that grease 1171 00:31:46,590 --> 00:31:49,940 one and of course the reason that grease cap is on there is i got this diagram 1172 00:31:49,940 --> 00:31:49,950 cap is on there is i got this diagram 1173 00:31:49,950 --> 00:31:52,730 cap is on there is i got this diagram from a truck manual and i didn't 1174 00:31:52,730 --> 00:31:52,740 from a truck manual and i didn't 1175 00:31:52,740 --> 00:31:54,380 from a truck manual and i didn't separate the grease cap from it that 1176 00:31:54,380 --> 00:31:54,390 separate the grease cap from it that 1177 00:31:54,390 --> 00:31:55,220 separate the grease cap from it that goes on after you've installed 1178 00:31:55,220 --> 00:31:55,230 goes on after you've installed 1179 00:31:55,230 --> 00:31:59,780 goes on after you've installed everything else now here is luck wearing 1180 00:31:59,780 --> 00:31:59,790 everything else now here is luck wearing 1181 00:31:59,790 --> 00:32:03,560 everything else now here is luck wearing which is normally used just by the 1182 00:32:03,560 --> 00:32:03,570 which is normally used just by the 1183 00:32:03,570 --> 00:32:06,620 which is normally used just by the aerospace industry because of the cost 1184 00:32:06,620 --> 00:32:06,630 aerospace industry because of the cost 1185 00:32:06,630 --> 00:32:12,440 aerospace industry because of the cost and labor involved because you are 1186 00:32:12,440 --> 00:32:12,450 and labor involved because you are 1187 00:32:12,450 --> 00:32:16,460 and labor involved because you are winding these wires on here through 1188 00:32:16,460 --> 00:32:16,470 winding these wires on here through 1189 00:32:16,470 --> 00:32:20,690 winding these wires on here through either holes straight through the top of 1190 00:32:20,690 --> 00:32:20,700 either holes straight through the top of 1191 00:32:20,700 --> 00:32:24,260 either holes straight through the top of the heads or in the case of the nut 1192 00:32:24,260 --> 00:32:24,270 the heads or in the case of the nut 1193 00:32:24,270 --> 00:32:25,910 the heads or in the case of the nut holes through the corners of the nuts 1194 00:32:25,910 --> 00:32:25,920 holes through the corners of the nuts 1195 00:32:25,920 --> 00:32:28,610 holes through the corners of the nuts you put these on in such a pattern that 1196 00:32:28,610 --> 00:32:28,620 you put these on in such a pattern that 1197 00:32:28,620 --> 00:32:30,890 you put these on in such a pattern that if you try to loosen one fastener it 1198 00:32:30,890 --> 00:32:30,900 if you try to loosen one fastener it 1199 00:32:30,900 --> 00:32:33,290 if you try to loosen one fastener it tightens the other one this way they 1200 00:32:33,290 --> 00:32:33,300 tightens the other one this way they 1201 00:32:33,300 --> 00:32:34,820 tightens the other one this way they can't loosen because they're all tied 1202 00:32:34,820 --> 00:32:34,830 can't loosen because they're all tied 1203 00:32:34,830 --> 00:32:40,550 can't loosen because they're all tied together and this is a method that is 1204 00:32:40,550 --> 00:32:40,560 together and this is a method that is 1205 00:32:40,560 --> 00:32:45,320 together and this is a method that is covered by an MS spec 30 35 40 you can 1206 00:32:45,320 --> 00:32:45,330 covered by an MS spec 30 35 40 you can 1207 00:32:45,330 --> 00:32:49,100 covered by an MS spec 30 35 40 you can use it quite well where you have a 1208 00:32:49,100 --> 00:32:49,110 use it quite well where you have a 1209 00:32:49,110 --> 00:32:51,350 use it quite well where you have a circular pattern of fasteners on a 1210 00:32:51,350 --> 00:32:51,360 circular pattern of fasteners on a 1211 00:32:51,360 --> 00:32:53,960 circular pattern of fasteners on a flange or something like that but the 1212 00:32:53,960 --> 00:32:53,970 flange or something like that but the 1213 00:32:53,970 --> 00:32:57,860 flange or something like that but the only people that use it in normal cases 1214 00:32:57,860 --> 00:32:57,870 only people that use it in normal cases 1215 00:32:57,870 --> 00:33:02,000 only people that use it in normal cases as the aerospace industry here is an 1216 00:33:02,000 --> 00:33:02,010 as the aerospace industry here is an 1217 00:33:02,010 --> 00:33:07,160 as the aerospace industry here is an alternative method to the lock wearing 1218 00:33:07,160 --> 00:33:07,170 alternative method to the lock wearing 1219 00:33:07,170 --> 00:33:10,130 alternative method to the lock wearing this is a similar thing in which you 1220 00:33:10,130 --> 00:33:10,140 this is a similar thing in which you 1221 00:33:10,140 --> 00:33:12,650 this is a similar thing in which you start out with a piece of cable by the 1222 00:33:12,650 --> 00:33:12,660 start out with a piece of cable by the 1223 00:33:12,660 --> 00:33:15,910 start out with a piece of cable by the Bergen cable company here that has a 1224 00:33:15,910 --> 00:33:15,920 Bergen cable company here that has a 1225 00:33:15,920 --> 00:33:18,680 Bergen cable company here that has a barrel already switched in place on it 1226 00:33:18,680 --> 00:33:18,690 barrel already switched in place on it 1227 00:33:18,690 --> 00:33:21,920 barrel already switched in place on it so you just feed it through you run the 1228 00:33:21,920 --> 00:33:21,930 so you just feed it through you run the 1229 00:33:21,930 --> 00:33:23,810 so you just feed it through you run the wire through the heads to wind them the 1230 00:33:23,810 --> 00:33:23,820 wire through the heads to wind them the 1231 00:33:23,820 --> 00:33:25,490 wire through the heads to wind them the same way so that one can't loosen 1232 00:33:25,490 --> 00:33:25,500 same way so that one can't loosen 1233 00:33:25,500 --> 00:33:27,050 same way so that one can't loosen without tightening the other one then 1234 00:33:27,050 --> 00:33:27,060 without tightening the other one then 1235 00:33:27,060 --> 00:33:28,460 without tightening the other one then when you get to the end you have a 1236 00:33:28,460 --> 00:33:28,470 when you get to the end you have a 1237 00:33:28,470 --> 00:33:32,780 when you get to the end you have a machine similar to a rivet gun or 1238 00:33:32,780 --> 00:33:32,790 machine similar to a rivet gun or 1239 00:33:32,790 --> 00:33:36,440 machine similar to a rivet gun or something that actually puts a barrel on 1240 00:33:36,440 --> 00:33:36,450 something that actually puts a barrel on 1241 00:33:36,450 --> 00:33:39,240 something that actually puts a barrel on here pulls the right tension on the wire 1242 00:33:39,240 --> 00:33:39,250 here pulls the right tension on the wire 1243 00:33:39,250 --> 00:33:41,300 here pulls the right tension on the wire and closes it off so that this is 1244 00:33:41,300 --> 00:33:41,310 and closes it off so that this is 1245 00:33:41,310 --> 00:33:44,370 and closes it off so that this is actually a faster and cheaper way of 1246 00:33:44,370 --> 00:33:44,380 actually a faster and cheaper way of 1247 00:33:44,380 --> 00:33:46,260 actually a faster and cheaper way of luck wearing than the standard luck 1248 00:33:46,260 --> 00:33:46,270 luck wearing than the standard luck 1249 00:33:46,270 --> 00:33:50,120 luck wearing than the standard luck wearing method with the twisted wire 1250 00:33:50,120 --> 00:33:50,130 1251 00:33:50,130 --> 00:33:54,290 this is the disc lock washer it is a 1252 00:33:54,290 --> 00:33:54,300 this is the disc lock washer it is a 1253 00:33:54,300 --> 00:33:58,110 this is the disc lock washer it is a little bit cumbersome in that you have a 1254 00:33:58,110 --> 00:33:58,120 little bit cumbersome in that you have a 1255 00:33:58,120 --> 00:34:01,200 little bit cumbersome in that you have a pair of washers together and these lines 1256 00:34:01,200 --> 00:34:01,210 pair of washers together and these lines 1257 00:34:01,210 --> 00:34:06,930 pair of washers together and these lines here represent the angles on them where 1258 00:34:06,930 --> 00:34:06,940 here represent the angles on them where 1259 00:34:06,940 --> 00:34:08,610 here represent the angles on them where you put the two together and turn them 1260 00:34:08,610 --> 00:34:08,620 you put the two together and turn them 1261 00:34:08,620 --> 00:34:10,830 you put the two together and turn them together now as long as you keep them 1262 00:34:10,830 --> 00:34:10,840 together now as long as you keep them 1263 00:34:10,840 --> 00:34:13,530 together now as long as you keep them together they can't rotate with with 1264 00:34:13,530 --> 00:34:13,540 together they can't rotate with with 1265 00:34:13,540 --> 00:34:18,629 together they can't rotate with with respect to each other so the angle of 1266 00:34:18,629 --> 00:34:18,639 respect to each other so the angle of 1267 00:34:18,639 --> 00:34:21,000 respect to each other so the angle of this ramp is steeper than the angle of 1268 00:34:21,000 --> 00:34:21,010 this ramp is steeper than the angle of 1269 00:34:21,010 --> 00:34:24,060 this ramp is steeper than the angle of the thread so it will keep it from 1270 00:34:24,060 --> 00:34:24,070 the thread so it will keep it from 1271 00:34:24,070 --> 00:34:27,659 the thread so it will keep it from turning however the bottom and top of 1272 00:34:27,659 --> 00:34:27,669 turning however the bottom and top of 1273 00:34:27,669 --> 00:34:29,389 turning however the bottom and top of those two washers have to have 1274 00:34:29,389 --> 00:34:29,399 those two washers have to have 1275 00:34:29,399 --> 00:34:31,619 those two washers have to have serrations on them that bite in the 1276 00:34:31,619 --> 00:34:31,629 serrations on them that bite in the 1277 00:34:31,629 --> 00:34:36,810 serrations on them that bite in the joint material and also the bottom of 1278 00:34:36,810 --> 00:34:36,820 joint material and also the bottom of 1279 00:34:36,820 --> 00:34:39,389 joint material and also the bottom of the nut in order to keep it from 1280 00:34:39,389 --> 00:34:39,399 the nut in order to keep it from 1281 00:34:39,399 --> 00:34:41,760 the nut in order to keep it from slipping with respect to the nut or the 1282 00:34:41,760 --> 00:34:41,770 slipping with respect to the nut or the 1283 00:34:41,770 --> 00:34:45,480 slipping with respect to the nut or the joint otherwise the washer will spend as 1284 00:34:45,480 --> 00:34:45,490 joint otherwise the washer will spend as 1285 00:34:45,490 --> 00:34:49,350 joint otherwise the washer will spend as a unit and doesn't help you any so so 1286 00:34:49,350 --> 00:34:49,360 a unit and doesn't help you any so so 1287 00:34:49,360 --> 00:34:52,379 a unit and doesn't help you any so so that one will work if you are not 1288 00:34:52,379 --> 00:34:52,389 that one will work if you are not 1289 00:34:52,389 --> 00:34:54,119 that one will work if you are not concerned with carrying the coating 1290 00:34:54,119 --> 00:34:54,129 concerned with carrying the coating 1291 00:34:54,129 --> 00:35:01,860 concerned with carrying the coating loose on the surfaces here is a kind of 1292 00:35:01,860 --> 00:35:01,870 loose on the surfaces here is a kind of 1293 00:35:01,870 --> 00:35:04,710 loose on the surfaces here is a kind of a take-off on the disc lock washers in 1294 00:35:04,710 --> 00:35:04,720 a take-off on the disc lock washers in 1295 00:35:04,720 --> 00:35:08,130 a take-off on the disc lock washers in that you have a nut assembly now this 1296 00:35:08,130 --> 00:35:08,140 that you have a nut assembly now this 1297 00:35:08,140 --> 00:35:12,300 that you have a nut assembly now this one has the ramp cheer and the lower 1298 00:35:12,300 --> 00:35:12,310 one has the ramp cheer and the lower 1299 00:35:12,310 --> 00:35:14,220 one has the ramp cheer and the lower part of it from here down is not 1300 00:35:14,220 --> 00:35:14,230 part of it from here down is not 1301 00:35:14,230 --> 00:35:16,350 part of it from here down is not threaded just the upper parts threaded 1302 00:35:16,350 --> 00:35:16,360 threaded just the upper parts threaded 1303 00:35:16,360 --> 00:35:17,730 threaded just the upper parts threaded well to see you put the two of them 1304 00:35:17,730 --> 00:35:17,740 well to see you put the two of them 1305 00:35:17,740 --> 00:35:20,810 well to see you put the two of them together you put them on with a socket 1306 00:35:20,810 --> 00:35:20,820 together you put them on with a socket 1307 00:35:20,820 --> 00:35:24,030 together you put them on with a socket extends down over both of them now this 1308 00:35:24,030 --> 00:35:24,040 extends down over both of them now this 1309 00:35:24,040 --> 00:35:27,450 extends down over both of them now this will hold the thing while you twurk it 1310 00:35:27,450 --> 00:35:27,460 will hold the thing while you twurk it 1311 00:35:27,460 --> 00:35:30,330 will hold the thing while you twurk it up and then of course the bottom surface 1312 00:35:30,330 --> 00:35:30,340 up and then of course the bottom surface 1313 00:35:30,340 --> 00:35:32,580 up and then of course the bottom surface of it has in serrations on it that bite 1314 00:35:32,580 --> 00:35:32,590 of it has in serrations on it that bite 1315 00:35:32,590 --> 00:35:36,650 of it has in serrations on it that bite into the attaching plane of the joint so 1316 00:35:36,650 --> 00:35:36,660 into the attaching plane of the joint so 1317 00:35:36,660 --> 00:35:39,690 into the attaching plane of the joint so once again you're scratching the surface 1318 00:35:39,690 --> 00:35:39,700 once again you're scratching the surface 1319 00:35:39,700 --> 00:35:43,530 once again you're scratching the surface you're attaching to however a company on 1320 00:35:43,530 --> 00:35:43,540 you're attaching to however a company on 1321 00:35:43,540 --> 00:35:46,400 you're attaching to however a company on the west coast makes these and the 1322 00:35:46,400 --> 00:35:46,410 the west coast makes these and the 1323 00:35:46,410 --> 00:35:48,540 the west coast makes these and the president of it told me that they had 1324 00:35:48,540 --> 00:35:48,550 president of it told me that they had 1325 00:35:48,550 --> 00:35:51,360 president of it told me that they had they were selling millions of these for 1326 00:35:51,360 --> 00:35:51,370 they were selling millions of these for 1327 00:35:51,370 --> 00:35:53,070 they were selling millions of these for the heavy truck industry 1328 00:35:53,070 --> 00:35:53,080 the heavy truck industry 1329 00:35:53,080 --> 00:35:55,080 the heavy truck industry because the heavy truck industries had a 1330 00:35:55,080 --> 00:35:55,090 because the heavy truck industries had a 1331 00:35:55,090 --> 00:35:56,880 because the heavy truck industries had a lot of trouble through the years with 1332 00:35:56,880 --> 00:35:56,890 lot of trouble through the years with 1333 00:35:56,890 --> 00:36:00,140 lot of trouble through the years with nuts coming off and wheels coming off so 1334 00:36:00,140 --> 00:36:00,150 nuts coming off and wheels coming off so 1335 00:36:00,150 --> 00:36:03,870 nuts coming off and wheels coming off so so they're paying for this type of nut 1336 00:36:03,870 --> 00:36:03,880 so they're paying for this type of nut 1337 00:36:03,880 --> 00:36:05,490 so they're paying for this type of nut in order to hold them on because they do 1338 00:36:05,490 --> 00:36:05,500 in order to hold them on because they do 1339 00:36:05,500 --> 00:36:10,830 in order to hold them on because they do work on holding truck wheels on here is 1340 00:36:10,830 --> 00:36:10,840 work on holding truck wheels on here is 1341 00:36:10,840 --> 00:36:14,580 work on holding truck wheels on here is a another method this is a durar lock 1342 00:36:14,580 --> 00:36:14,590 a another method this is a durar lock 1343 00:36:14,590 --> 00:36:18,780 a another method this is a durar lock nut which is a trademark of SPS which 1344 00:36:18,780 --> 00:36:18,790 nut which is a trademark of SPS which 1345 00:36:18,790 --> 00:36:20,730 nut which is a trademark of SPS which one of the one of the big manufacturers 1346 00:36:20,730 --> 00:36:20,740 one of the one of the big manufacturers 1347 00:36:20,740 --> 00:36:24,780 one of the one of the big manufacturers of fasteners it has serrations on it 1348 00:36:24,780 --> 00:36:24,790 of fasteners it has serrations on it 1349 00:36:24,790 --> 00:36:28,410 of fasteners it has serrations on it here that bite into the surface so that 1350 00:36:28,410 --> 00:36:28,420 here that bite into the surface so that 1351 00:36:28,420 --> 00:36:32,220 here that bite into the surface so that it will not slip and start loosening up 1352 00:36:32,220 --> 00:36:32,230 it will not slip and start loosening up 1353 00:36:32,230 --> 00:36:34,680 it will not slip and start loosening up once you get it tight now you have to 1354 00:36:34,680 --> 00:36:34,690 once you get it tight now you have to 1355 00:36:34,690 --> 00:36:36,570 once you get it tight now you have to depend on this embedment of the 1356 00:36:36,570 --> 00:36:36,580 depend on this embedment of the 1357 00:36:36,580 --> 00:36:38,730 depend on this embedment of the serrations in the contact surfaces and 1358 00:36:38,730 --> 00:36:38,740 serrations in the contact surfaces and 1359 00:36:38,740 --> 00:36:40,950 serrations in the contact surfaces and so it will scratch up the surface if you 1360 00:36:40,950 --> 00:36:40,960 so it will scratch up the surface if you 1361 00:36:40,960 --> 00:36:44,880 so it will scratch up the surface if you can live with that this one will do a 1362 00:36:44,880 --> 00:36:44,890 can live with that this one will do a 1363 00:36:44,890 --> 00:36:50,580 can live with that this one will do a pretty good job of locking here are two 1364 00:36:50,580 --> 00:36:50,590 pretty good job of locking here are two 1365 00:36:50,590 --> 00:36:54,260 pretty good job of locking here are two flock washers which are common in the 1366 00:36:54,260 --> 00:36:54,270 flock washers which are common in the 1367 00:36:54,270 --> 00:36:57,410 flock washers which are common in the electrical and automotive industry 1368 00:36:57,410 --> 00:36:57,420 electrical and automotive industry 1369 00:36:57,420 --> 00:37:00,990 electrical and automotive industry because they do afford locking oh and 1370 00:37:00,990 --> 00:37:01,000 because they do afford locking oh and 1371 00:37:01,000 --> 00:37:03,060 because they do afford locking oh and but once again they do it by gouging 1372 00:37:03,060 --> 00:37:03,070 but once again they do it by gouging 1373 00:37:03,070 --> 00:37:07,800 but once again they do it by gouging into things they these teeth are twisted 1374 00:37:07,800 --> 00:37:07,810 into things they these teeth are twisted 1375 00:37:07,810 --> 00:37:09,540 into things they these teeth are twisted although this doesn't show it they're 1376 00:37:09,540 --> 00:37:09,550 although this doesn't show it they're 1377 00:37:09,550 --> 00:37:12,180 although this doesn't show it they're actually twisted so that you have one 1378 00:37:12,180 --> 00:37:12,190 actually twisted so that you have one 1379 00:37:12,190 --> 00:37:16,500 actually twisted so that you have one surface bites into the fastener the 1380 00:37:16,500 --> 00:37:16,510 surface bites into the fastener the 1381 00:37:16,510 --> 00:37:18,240 surface bites into the fastener the other one bites into the surface that 1382 00:37:18,240 --> 00:37:18,250 other one bites into the surface that 1383 00:37:18,250 --> 00:37:24,450 other one bites into the surface that it's up against so that it will get 1384 00:37:24,450 --> 00:37:24,460 it's up against so that it will get 1385 00:37:24,460 --> 00:37:26,340 it's up against so that it will get enough bite on both of them to hold them 1386 00:37:26,340 --> 00:37:26,350 enough bite on both of them to hold them 1387 00:37:26,350 --> 00:37:31,130 enough bite on both of them to hold them in place and prevent rotation however 1388 00:37:31,130 --> 00:37:31,140 in place and prevent rotation however 1389 00:37:31,140 --> 00:37:34,320 in place and prevent rotation however you damage the surface quite a bit now 1390 00:37:34,320 --> 00:37:34,330 you damage the surface quite a bit now 1391 00:37:34,330 --> 00:37:36,720 you damage the surface quite a bit now this one is also available with teeth on 1392 00:37:36,720 --> 00:37:36,730 this one is also available with teeth on 1393 00:37:36,730 --> 00:37:39,900 this one is also available with teeth on the inside so that the outside is smooth 1394 00:37:39,900 --> 00:37:39,910 the inside so that the outside is smooth 1395 00:37:39,910 --> 00:37:41,610 the inside so that the outside is smooth in areas where you don't have room 1396 00:37:41,610 --> 00:37:41,620 in areas where you don't have room 1397 00:37:41,620 --> 00:37:44,820 in areas where you don't have room enough to have it stick out that much 1398 00:37:44,820 --> 00:37:44,830 enough to have it stick out that much 1399 00:37:44,830 --> 00:37:46,200 enough to have it stick out that much you can you can get them with the teeth 1400 00:37:46,200 --> 00:37:46,210 you can you can get them with the teeth 1401 00:37:46,210 --> 00:37:51,140 you can you can get them with the teeth on the inside 1402 00:37:51,140 --> 00:37:51,150 1403 00:37:51,150 --> 00:37:56,600 here is the old famous jam nut which is 1404 00:37:56,600 --> 00:37:56,610 here is the old famous jam nut which is 1405 00:37:56,610 --> 00:37:59,250 here is the old famous jam nut which is one that if I polled the people in the 1406 00:37:59,250 --> 00:37:59,260 one that if I polled the people in the 1407 00:37:59,260 --> 00:38:03,480 one that if I polled the people in the audience neither one would be able to 1408 00:38:03,480 --> 00:38:03,490 audience neither one would be able to 1409 00:38:03,490 --> 00:38:05,370 audience neither one would be able to give me a positive answer on which side 1410 00:38:05,370 --> 00:38:05,380 give me a positive answer on which side 1411 00:38:05,380 --> 00:38:07,140 give me a positive answer on which side you put this and whether you put it here 1412 00:38:07,140 --> 00:38:07,150 you put this and whether you put it here 1413 00:38:07,150 --> 00:38:08,670 you put this and whether you put it here where it's showing or you've already put 1414 00:38:08,670 --> 00:38:08,680 where it's showing or you've already put 1415 00:38:08,680 --> 00:38:10,380 where it's showing or you've already put the big one on the inside and the little 1416 00:38:10,380 --> 00:38:10,390 the big one on the inside and the little 1417 00:38:10,390 --> 00:38:12,810 the big one on the inside and the little one on the outside because the experts 1418 00:38:12,810 --> 00:38:12,820 one on the outside because the experts 1419 00:38:12,820 --> 00:38:16,230 one on the outside because the experts can agree on that it's difficult to load 1420 00:38:16,230 --> 00:38:16,240 can agree on that it's difficult to load 1421 00:38:16,240 --> 00:38:18,000 can agree on that it's difficult to load each one of these so that it'll carry 1422 00:38:18,000 --> 00:38:18,010 each one of these so that it'll carry 1423 00:38:18,010 --> 00:38:21,330 each one of these so that it'll carry any load compared to the other ones 1424 00:38:21,330 --> 00:38:21,340 any load compared to the other ones 1425 00:38:21,340 --> 00:38:23,610 any load compared to the other ones because if you if you tighten this one 1426 00:38:23,610 --> 00:38:23,620 because if you if you tighten this one 1427 00:38:23,620 --> 00:38:28,890 because if you if you tighten this one tight it will unload this one and if you 1428 00:38:28,890 --> 00:38:28,900 tight it will unload this one and if you 1429 00:38:28,900 --> 00:38:32,760 tight it will unload this one and if you don't tighten it enough then the two of 1430 00:38:32,760 --> 00:38:32,770 don't tighten it enough then the two of 1431 00:38:32,770 --> 00:38:34,920 don't tighten it enough then the two of them will not work together so it's very 1432 00:38:34,920 --> 00:38:34,930 them will not work together so it's very 1433 00:38:34,930 --> 00:38:36,900 them will not work together so it's very difficult to get both of these loaded to 1434 00:38:36,900 --> 00:38:36,910 difficult to get both of these loaded to 1435 00:38:36,910 --> 00:38:40,620 difficult to get both of these loaded to where they would carry a load so jam 1436 00:38:40,620 --> 00:38:40,630 where they would carry a load so jam 1437 00:38:40,630 --> 00:38:42,450 where they would carry a load so jam nuts in my opinion are not to be used 1438 00:38:42,450 --> 00:38:42,460 nuts in my opinion are not to be used 1439 00:38:42,460 --> 00:38:45,810 nuts in my opinion are not to be used for critical designs unless it's 1440 00:38:45,810 --> 00:38:45,820 for critical designs unless it's 1441 00:38:45,820 --> 00:38:49,160 for critical designs unless it's something like locking a turnbuckle or 1442 00:38:49,160 --> 00:38:49,170 something like locking a turnbuckle or 1443 00:38:49,170 --> 00:38:52,170 something like locking a turnbuckle or some sort of a rod where something else 1444 00:38:52,170 --> 00:38:52,180 some sort of a rod where something else 1445 00:38:52,180 --> 00:38:53,700 some sort of a rod where something else carries all the load and you're just 1446 00:38:53,700 --> 00:38:53,710 carries all the load and you're just 1447 00:38:53,710 --> 00:38:55,830 carries all the load and you're just pushing this up against it to keep it 1448 00:38:55,830 --> 00:38:55,840 pushing this up against it to keep it 1449 00:38:55,840 --> 00:39:00,840 pushing this up against it to keep it from working loose and here is the good 1450 00:39:00,840 --> 00:39:00,850 from working loose and here is the good 1451 00:39:00,850 --> 00:39:05,700 from working loose and here is the good old split helical up were sure which is 1452 00:39:05,700 --> 00:39:05,710 old split helical up were sure which is 1453 00:39:05,710 --> 00:39:08,630 old split helical up were sure which is a misnomer because once you compress it 1454 00:39:08,630 --> 00:39:08,640 a misnomer because once you compress it 1455 00:39:08,640 --> 00:39:12,990 a misnomer because once you compress it under normal bolt torque it will flatten 1456 00:39:12,990 --> 00:39:13,000 under normal bolt torque it will flatten 1457 00:39:13,000 --> 00:39:15,300 under normal bolt torque it will flatten out and then this is the flat washer 1458 00:39:15,300 --> 00:39:15,310 out and then this is the flat washer 1459 00:39:15,310 --> 00:39:16,920 out and then this is the flat washer anyway which doesn't do anything for you 1460 00:39:16,920 --> 00:39:16,930 anyway which doesn't do anything for you 1461 00:39:16,930 --> 00:39:20,940 anyway which doesn't do anything for you and vibration testing of the split lock 1462 00:39:20,940 --> 00:39:20,950 and vibration testing of the split lock 1463 00:39:20,950 --> 00:39:23,610 and vibration testing of the split lock washers assemblies indicate that they're 1464 00:39:23,610 --> 00:39:23,620 washers assemblies indicate that they're 1465 00:39:23,620 --> 00:39:25,440 washers assemblies indicate that they're about us the same as a flat 4shared 1466 00:39:25,440 --> 00:39:25,450 about us the same as a flat 4shared 1467 00:39:25,450 --> 00:39:29,580 about us the same as a flat 4shared resist vibration and I don't recommend 1468 00:39:29,580 --> 00:39:29,590 resist vibration and I don't recommend 1469 00:39:29,590 --> 00:39:32,460 resist vibration and I don't recommend them for any kind of a locking situation 1470 00:39:32,460 --> 00:39:32,470 them for any kind of a locking situation 1471 00:39:32,470 --> 00:39:36,450 them for any kind of a locking situation although I was sharply criticized for 1472 00:39:36,450 --> 00:39:36,460 although I was sharply criticized for 1473 00:39:36,460 --> 00:39:38,990 although I was sharply criticized for writing this in a fastener magazine 1474 00:39:38,990 --> 00:39:39,000 writing this in a fastener magazine 1475 00:39:39,000 --> 00:39:41,580 writing this in a fastener magazine because the person who wrote in the 1476 00:39:41,580 --> 00:39:41,590 because the person who wrote in the 1477 00:39:41,590 --> 00:39:45,030 because the person who wrote in the criticism was a manufacturer of split 1478 00:39:45,030 --> 00:39:45,040 criticism was a manufacturer of split 1479 00:39:45,040 --> 00:39:46,650 criticism was a manufacturer of split lock washers so he didn't like it 1480 00:39:46,650 --> 00:39:46,660 lock washers so he didn't like it 1481 00:39:46,660 --> 00:39:49,110 lock washers so he didn't like it because I said his his product was 1482 00:39:49,110 --> 00:39:49,120 because I said his his product was 1483 00:39:49,120 --> 00:39:52,410 because I said his his product was worthless for locking now here is a 1484 00:39:52,410 --> 00:39:52,420 worthless for locking now here is a 1485 00:39:52,420 --> 00:39:57,660 worthless for locking now here is a method that is used some but it's kind 1486 00:39:57,660 --> 00:39:57,670 method that is used some but it's kind 1487 00:39:57,670 --> 00:40:00,930 method that is used some but it's kind of a going a long ways to do your 1488 00:40:00,930 --> 00:40:00,940 of a going a long ways to do your 1489 00:40:00,940 --> 00:40:04,440 of a going a long ways to do your locking as I see it it 1490 00:40:04,440 --> 00:40:04,450 locking as I see it it 1491 00:40:04,450 --> 00:40:06,390 locking as I see it it this is a trademark of some company on 1492 00:40:06,390 --> 00:40:06,400 this is a trademark of some company on 1493 00:40:06,400 --> 00:40:09,540 this is a trademark of some company on the west coast age 8 and you see what 1494 00:40:09,540 --> 00:40:09,550 the west coast age 8 and you see what 1495 00:40:09,550 --> 00:40:16,740 the west coast age 8 and you see what you have is a special boat that has a 1496 00:40:16,740 --> 00:40:16,750 you have is a special boat that has a 1497 00:40:16,750 --> 00:40:18,750 you have is a special boat that has a kind of the double-headed one with a 1498 00:40:18,750 --> 00:40:18,760 kind of the double-headed one with a 1499 00:40:18,760 --> 00:40:21,390 kind of the double-headed one with a groove machined in it which creates the 1500 00:40:21,390 --> 00:40:21,400 groove machined in it which creates the 1501 00:40:21,400 --> 00:40:24,599 groove machined in it which creates the little problem on initial manufacturing 1502 00:40:24,599 --> 00:40:24,609 little problem on initial manufacturing 1503 00:40:24,609 --> 00:40:28,319 little problem on initial manufacturing then you have a retainer plate that 1504 00:40:28,319 --> 00:40:28,329 then you have a retainer plate that 1505 00:40:28,329 --> 00:40:32,339 then you have a retainer plate that slides down over this outer head on to 1506 00:40:32,339 --> 00:40:32,349 slides down over this outer head on to 1507 00:40:32,349 --> 00:40:38,280 slides down over this outer head on to the bottom one then you use this snap 1508 00:40:38,280 --> 00:40:38,290 the bottom one then you use this snap 1509 00:40:38,290 --> 00:40:41,460 the bottom one then you use this snap ring to put in that groove to lock the 1510 00:40:41,460 --> 00:40:41,470 ring to put in that groove to lock the 1511 00:40:41,470 --> 00:40:45,750 ring to put in that groove to lock the thing in place now you do this after 1512 00:40:45,750 --> 00:40:45,760 thing in place now you do this after 1513 00:40:45,760 --> 00:40:48,990 thing in place now you do this after you've already took the bolt to the spot 1514 00:40:48,990 --> 00:40:49,000 you've already took the bolt to the spot 1515 00:40:49,000 --> 00:40:51,930 you've already took the bolt to the spot that you want it now the only thing is 1516 00:40:51,930 --> 00:40:51,940 that you want it now the only thing is 1517 00:40:51,940 --> 00:40:56,099 that you want it now the only thing is you have to have something for this to 1518 00:40:56,099 --> 00:40:56,109 you have to have something for this to 1519 00:40:56,109 --> 00:41:01,680 you have to have something for this to brace against to keep the bolt from 1520 00:41:01,680 --> 00:41:01,690 brace against to keep the bolt from 1521 00:41:01,690 --> 00:41:04,800 brace against to keep the bolt from backing off so it has to be a special 1522 00:41:04,800 --> 00:41:04,810 backing off so it has to be a special 1523 00:41:04,810 --> 00:41:07,440 backing off so it has to be a special design in that respect and then the 1524 00:41:07,440 --> 00:41:07,450 design in that respect and then the 1525 00:41:07,450 --> 00:41:11,460 design in that respect and then the other problem that I had on the control 1526 00:41:11,460 --> 00:41:11,470 other problem that I had on the control 1527 00:41:11,470 --> 00:41:15,930 other problem that I had on the control arms on a Ford wagon this retainer plate 1528 00:41:15,930 --> 00:41:15,940 arms on a Ford wagon this retainer plate 1529 00:41:15,940 --> 00:41:19,740 arms on a Ford wagon this retainer plate is made out of sheet metal over a period 1530 00:41:19,740 --> 00:41:19,750 is made out of sheet metal over a period 1531 00:41:19,750 --> 00:41:22,650 is made out of sheet metal over a period of time it will rust up on you and then 1532 00:41:22,650 --> 00:41:22,660 of time it will rust up on you and then 1533 00:41:22,660 --> 00:41:24,750 of time it will rust up on you and then you go to loosen this thing for a front 1534 00:41:24,750 --> 00:41:24,760 you go to loosen this thing for a front 1535 00:41:24,760 --> 00:41:27,150 you go to loosen this thing for a front end alignment and the retainer plate 1536 00:41:27,150 --> 00:41:27,160 end alignment and the retainer plate 1537 00:41:27,160 --> 00:41:30,470 end alignment and the retainer plate comes off and you can't get in there to 1538 00:41:30,470 --> 00:41:30,480 comes off and you can't get in there to 1539 00:41:30,480 --> 00:41:33,930 comes off and you can't get in there to get anything else on it loosen it so 1540 00:41:33,930 --> 00:41:33,940 get anything else on it loosen it so 1541 00:41:33,940 --> 00:41:37,200 get anything else on it loosen it so that one is one that I would not 1542 00:41:37,200 --> 00:41:37,210 that one is one that I would not 1543 00:41:37,210 --> 00:41:39,569 that one is one that I would not recommend in any environment where you 1544 00:41:39,569 --> 00:41:39,579 recommend in any environment where you 1545 00:41:39,579 --> 00:41:46,400 recommend in any environment where you would have corrosion now getting into 1546 00:41:46,400 --> 00:41:46,410 would have corrosion now getting into 1547 00:41:46,410 --> 00:41:48,690 would have corrosion now getting into washers and out some of them we've 1548 00:41:48,690 --> 00:41:48,700 washers and out some of them we've 1549 00:41:48,700 --> 00:41:53,520 washers and out some of them we've already covered so we won't do a lot on 1550 00:41:53,520 --> 00:41:53,530 already covered so we won't do a lot on 1551 00:41:53,530 --> 00:41:57,150 already covered so we won't do a lot on summon the most of them are flat they're 1552 00:41:57,150 --> 00:41:57,160 summon the most of them are flat they're 1553 00:41:57,160 --> 00:41:58,829 summon the most of them are flat they're used to provide a hardened smooth 1554 00:41:58,829 --> 00:41:58,839 used to provide a hardened smooth 1555 00:41:58,839 --> 00:42:00,809 used to provide a hardened smooth surface for the contact of a fastener 1556 00:42:00,809 --> 00:42:00,819 surface for the contact of a fastener 1557 00:42:00,819 --> 00:42:02,970 surface for the contact of a fastener header nut and that's that's really one 1558 00:42:02,970 --> 00:42:02,980 header nut and that's that's really one 1559 00:42:02,980 --> 00:42:04,740 header nut and that's that's really one of the the main reasons for using 1560 00:42:04,740 --> 00:42:04,750 of the the main reasons for using 1561 00:42:04,750 --> 00:42:06,839 of the the main reasons for using worships both under the head and the nut 1562 00:42:06,839 --> 00:42:06,849 worships both under the head and the nut 1563 00:42:06,849 --> 00:42:09,770 worships both under the head and the nut is if if you are rotating either one 1564 00:42:09,770 --> 00:42:09,780 is if if you are rotating either one 1565 00:42:09,780 --> 00:42:13,260 is if if you are rotating either one usually the joint surface is not as 1566 00:42:13,260 --> 00:42:13,270 usually the joint surface is not as 1567 00:42:13,270 --> 00:42:15,450 usually the joint surface is not as strong as the fastener so therefore you 1568 00:42:15,450 --> 00:42:15,460 strong as the fastener so therefore you 1569 00:42:15,460 --> 00:42:17,450 strong as the fastener so therefore you you have to have that too 1570 00:42:17,450 --> 00:42:17,460 you have to have that too 1571 00:42:17,460 --> 00:42:22,820 you have to have that too avoid embedment and then here's another 1572 00:42:22,820 --> 00:42:22,830 avoid embedment and then here's another 1573 00:42:22,830 --> 00:42:25,820 avoid embedment and then here's another one for shade tree mechanics if you have 1574 00:42:25,820 --> 00:42:25,830 one for shade tree mechanics if you have 1575 00:42:25,830 --> 00:42:29,570 one for shade tree mechanics if you have a washer under a bolt and it's rusted in 1576 00:42:29,570 --> 00:42:29,580 a washer under a bolt and it's rusted in 1577 00:42:29,580 --> 00:42:33,050 a washer under a bolt and it's rusted in place usually you can take a cold chisel 1578 00:42:33,050 --> 00:42:33,060 place usually you can take a cold chisel 1579 00:42:33,060 --> 00:42:34,880 place usually you can take a cold chisel and a hammer and not the washer 1580 00:42:34,880 --> 00:42:34,890 and a hammer and not the washer 1581 00:42:34,890 --> 00:42:37,280 and a hammer and not the washer laterally and get it get it loosened 1582 00:42:37,280 --> 00:42:37,290 laterally and get it get it loosened 1583 00:42:37,290 --> 00:42:40,400 laterally and get it get it loosened some so that you can loosen the bolt and 1584 00:42:40,400 --> 00:42:40,410 some so that you can loosen the bolt and 1585 00:42:40,410 --> 00:42:46,190 some so that you can loosen the bolt and washer now here's the plain flat and 1586 00:42:46,190 --> 00:42:46,200 washer now here's the plain flat and 1587 00:42:46,200 --> 00:42:50,270 washer now here's the plain flat and countersunk type for sures the here this 1588 00:42:50,270 --> 00:42:50,280 countersunk type for sures the here this 1589 00:42:50,280 --> 00:42:52,490 countersunk type for sures the here this is the ordinary hardware store variety 1590 00:42:52,490 --> 00:42:52,500 is the ordinary hardware store variety 1591 00:42:52,500 --> 00:42:55,460 is the ordinary hardware store variety and they're covered by all kinds of 1592 00:42:55,460 --> 00:42:55,470 and they're covered by all kinds of 1593 00:42:55,470 --> 00:42:59,180 and they're covered by all kinds of standards there's msan antsy so on which 1594 00:42:59,180 --> 00:42:59,190 standards there's msan antsy so on which 1595 00:42:59,190 --> 00:43:01,609 standards there's msan antsy so on which defines the outside diameter inside 1596 00:43:01,609 --> 00:43:01,619 defines the outside diameter inside 1597 00:43:01,619 --> 00:43:03,560 defines the outside diameter inside diameter and thickness for a given size 1598 00:43:03,560 --> 00:43:03,570 diameter and thickness for a given size 1599 00:43:03,570 --> 00:43:06,620 diameter and thickness for a given size so so normally you can just call out a 1600 00:43:06,620 --> 00:43:06,630 so so normally you can just call out a 1601 00:43:06,630 --> 00:43:08,810 so so normally you can just call out a dash number from one of these specs and 1602 00:43:08,810 --> 00:43:08,820 dash number from one of these specs and 1603 00:43:08,820 --> 00:43:13,370 dash number from one of these specs and your your cupboard the counter sunk 1604 00:43:13,370 --> 00:43:13,380 your your cupboard the counter sunk 1605 00:43:13,380 --> 00:43:15,290 your your cupboard the counter sunk coursers are made with the countersink 1606 00:43:15,290 --> 00:43:15,300 coursers are made with the countersink 1607 00:43:15,300 --> 00:43:18,020 coursers are made with the countersink in them we're on a high-strength boat 1608 00:43:18,020 --> 00:43:18,030 in them we're on a high-strength boat 1609 00:43:18,030 --> 00:43:21,829 in them we're on a high-strength boat you have a larger radius under the head 1610 00:43:21,829 --> 00:43:21,839 you have a larger radius under the head 1611 00:43:21,839 --> 00:43:25,820 you have a larger radius under the head so you don't want point contact if it is 1612 00:43:25,820 --> 00:43:25,830 so you don't want point contact if it is 1613 00:43:25,830 --> 00:43:27,710 so you don't want point contact if it is this diameter is tight you could get 1614 00:43:27,710 --> 00:43:27,720 this diameter is tight you could get 1615 00:43:27,720 --> 00:43:30,800 this diameter is tight you could get point contact on the head radius so you 1616 00:43:30,800 --> 00:43:30,810 point contact on the head radius so you 1617 00:43:30,810 --> 00:43:33,560 point contact on the head radius so you want to counter sunk so that it will now 1618 00:43:33,560 --> 00:43:33,570 want to counter sunk so that it will now 1619 00:43:33,570 --> 00:43:35,359 want to counter sunk so that it will now distribute the load better under the 1620 00:43:35,359 --> 00:43:35,369 distribute the load better under the 1621 00:43:35,369 --> 00:43:38,540 distribute the load better under the head and you won't have that high stress 1622 00:43:38,540 --> 00:43:38,550 head and you won't have that high stress 1623 00:43:38,550 --> 00:43:44,210 head and you won't have that high stress concentration at the radius now on the 1624 00:43:44,210 --> 00:43:44,220 concentration at the radius now on the 1625 00:43:44,220 --> 00:43:47,180 concentration at the radius now on the course we covered the split lock washer 1626 00:43:47,180 --> 00:43:47,190 course we covered the split lock washer 1627 00:43:47,190 --> 00:43:49,280 course we covered the split lock washer the tooth lock washer and the disc lock 1628 00:43:49,280 --> 00:43:49,290 the tooth lock washer and the disc lock 1629 00:43:49,290 --> 00:43:50,960 the tooth lock washer and the disc lock washer I just wanted to point out that 1630 00:43:50,960 --> 00:43:50,970 washer I just wanted to point out that 1631 00:43:50,970 --> 00:43:52,550 washer I just wanted to point out that we'd already covered those in case 1632 00:43:52,550 --> 00:43:52,560 we'd already covered those in case 1633 00:43:52,560 --> 00:43:54,730 we'd already covered those in case somebody would wonder if why we hadn't 1634 00:43:54,730 --> 00:43:54,740 somebody would wonder if why we hadn't 1635 00:43:54,740 --> 00:43:59,870 somebody would wonder if why we hadn't then we go on to a another unique type 1636 00:43:59,870 --> 00:43:59,880 then we go on to a another unique type 1637 00:43:59,880 --> 00:44:01,609 then we go on to a another unique type and this is used a lot in the 1638 00:44:01,609 --> 00:44:01,619 and this is used a lot in the 1639 00:44:01,619 --> 00:44:04,370 and this is used a lot in the construction business the DTI of worship 1640 00:44:04,370 --> 00:44:04,380 construction business the DTI of worship 1641 00:44:04,380 --> 00:44:09,220 construction business the DTI of worship the direct tension indicating it is a 1642 00:44:09,220 --> 00:44:09,230 the direct tension indicating it is a 1643 00:44:09,230 --> 00:44:12,560 the direct tension indicating it is a flat ground washer that has these bumps 1644 00:44:12,560 --> 00:44:12,570 flat ground washer that has these bumps 1645 00:44:12,570 --> 00:44:18,160 flat ground washer that has these bumps stamped on it and but you have to use 1646 00:44:18,160 --> 00:44:18,170 stamped on it and but you have to use 1647 00:44:18,170 --> 00:44:22,760 stamped on it and but you have to use regular washers in addition to these in 1648 00:44:22,760 --> 00:44:22,770 regular washers in addition to these in 1649 00:44:22,770 --> 00:44:24,790 regular washers in addition to these in order to distribute the load properly 1650 00:44:24,790 --> 00:44:24,800 order to distribute the load properly 1651 00:44:24,800 --> 00:44:27,260 order to distribute the load properly because you don't want these grinding 1652 00:44:27,260 --> 00:44:27,270 because you don't want these grinding 1653 00:44:27,270 --> 00:44:31,069 because you don't want these grinding against the head or not of your boat 1654 00:44:31,069 --> 00:44:31,079 against the head or not of your boat 1655 00:44:31,079 --> 00:44:34,940 against the head or not of your boat and actually these are manufactured and 1656 00:44:34,940 --> 00:44:34,950 and actually these are manufactured and 1657 00:44:34,950 --> 00:44:37,880 and actually these are manufactured and they do tests to determine the loads on 1658 00:44:37,880 --> 00:44:37,890 they do tests to determine the loads on 1659 00:44:37,890 --> 00:44:40,190 they do tests to determine the loads on them if we're the amount of compression 1660 00:44:40,190 --> 00:44:40,200 them if we're the amount of compression 1661 00:44:40,200 --> 00:44:45,109 them if we're the amount of compression that you get on the bumps determines the 1662 00:44:45,109 --> 00:44:45,119 that you get on the bumps determines the 1663 00:44:45,119 --> 00:44:47,959 that you get on the bumps determines the axial load in the bolt so you took the 1664 00:44:47,959 --> 00:44:47,969 axial load in the bolt so you took the 1665 00:44:47,969 --> 00:44:51,920 axial load in the bolt so you took the thing with a torque wrench without 1666 00:44:51,920 --> 00:44:51,930 thing with a torque wrench without 1667 00:44:51,930 --> 00:44:54,489 thing with a torque wrench without reading the torque unless you want to 1668 00:44:54,489 --> 00:44:54,499 reading the torque unless you want to 1669 00:44:54,499 --> 00:44:56,839 reading the torque unless you want to down to the point that you have a 1670 00:44:56,839 --> 00:44:56,849 down to the point that you have a 1671 00:44:56,849 --> 00:45:01,160 down to the point that you have a certain gap left and underneath the 1672 00:45:01,160 --> 00:45:01,170 certain gap left and underneath the 1673 00:45:01,170 --> 00:45:04,069 certain gap left and underneath the washer and the bumps and you measure it 1674 00:45:04,069 --> 00:45:04,079 washer and the bumps and you measure it 1675 00:45:04,079 --> 00:45:05,989 washer and the bumps and you measure it with a feeler gauge so this way 1676 00:45:05,989 --> 00:45:05,999 with a feeler gauge so this way 1677 00:45:05,999 --> 00:45:09,859 with a feeler gauge so this way regardless of the coefficients of 1678 00:45:09,859 --> 00:45:09,869 regardless of the coefficients of 1679 00:45:09,869 --> 00:45:11,959 regardless of the coefficients of friction on the threads or the head or 1680 00:45:11,959 --> 00:45:11,969 friction on the threads or the head or 1681 00:45:11,969 --> 00:45:13,880 friction on the threads or the head or anything you can actually torque it down 1682 00:45:13,880 --> 00:45:13,890 anything you can actually torque it down 1683 00:45:13,890 --> 00:45:17,479 anything you can actually torque it down to where the gap you get will tell you 1684 00:45:17,479 --> 00:45:17,489 to where the gap you get will tell you 1685 00:45:17,489 --> 00:45:24,910 to where the gap you get will tell you how much axial load you have in the bowl 1686 00:45:24,910 --> 00:45:24,920 1687 00:45:24,920 --> 00:45:28,160 now here's our old familiar belleville 1688 00:45:28,160 --> 00:45:28,170 now here's our old familiar belleville 1689 00:45:28,170 --> 00:45:33,410 now here's our old familiar belleville washers that named after the inventor 1690 00:45:33,410 --> 00:45:33,420 washers that named after the inventor 1691 00:45:33,420 --> 00:45:36,439 washers that named after the inventor who invented them way back in 1867 so 1692 00:45:36,439 --> 00:45:36,449 who invented them way back in 1867 so 1693 00:45:36,449 --> 00:45:40,459 who invented them way back in 1867 so they've been around a while it's also 1694 00:45:40,459 --> 00:45:40,469 they've been around a while it's also 1695 00:45:40,469 --> 00:45:43,130 they've been around a while it's also known as a comb washer or spring washer 1696 00:45:43,130 --> 00:45:43,140 known as a comb washer or spring washer 1697 00:45:43,140 --> 00:45:51,880 known as a comb washer or spring washer and these are designed with a load 1698 00:45:51,880 --> 00:45:51,890 and these are designed with a load 1699 00:45:51,890 --> 00:45:55,219 and these are designed with a load preload determination for a given washer 1700 00:45:55,219 --> 00:45:55,229 preload determination for a given washer 1701 00:45:55,229 --> 00:45:57,650 preload determination for a given washer or how much it takes the platen it and 1702 00:45:57,650 --> 00:45:57,660 or how much it takes the platen it and 1703 00:45:57,660 --> 00:46:00,529 or how much it takes the platen it and it will flatten elastically so a lot of 1704 00:46:00,529 --> 00:46:00,539 it will flatten elastically so a lot of 1705 00:46:00,539 --> 00:46:02,719 it will flatten elastically so a lot of times you can use them in a critical 1706 00:46:02,719 --> 00:46:02,729 times you can use them in a critical 1707 00:46:02,729 --> 00:46:06,979 times you can use them in a critical application where you want to limit the 1708 00:46:06,979 --> 00:46:06,989 application where you want to limit the 1709 00:46:06,989 --> 00:46:09,319 application where you want to limit the amount of axial load you have if you put 1710 00:46:09,319 --> 00:46:09,329 amount of axial load you have if you put 1711 00:46:09,329 --> 00:46:12,049 amount of axial load you have if you put a Belleville washer on and tell the 1712 00:46:12,049 --> 00:46:12,059 a Belleville washer on and tell the 1713 00:46:12,059 --> 00:46:14,479 a Belleville washer on and tell the mechanic okay just perk this thing until 1714 00:46:14,479 --> 00:46:14,489 mechanic okay just perk this thing until 1715 00:46:14,489 --> 00:46:16,370 mechanic okay just perk this thing until the washer starts to go flat and then 1716 00:46:16,370 --> 00:46:16,380 the washer starts to go flat and then 1717 00:46:16,380 --> 00:46:17,809 the washer starts to go flat and then quit regardless of what your torque 1718 00:46:17,809 --> 00:46:17,819 quit regardless of what your torque 1719 00:46:17,819 --> 00:46:23,439 quit regardless of what your torque wrench says it also can be used for 1720 00:46:23,439 --> 00:46:23,449 wrench says it also can be used for 1721 00:46:23,449 --> 00:46:26,449 wrench says it also can be used for absorbing differential thermal expansion 1722 00:46:26,449 --> 00:46:26,459 absorbing differential thermal expansion 1723 00:46:26,459 --> 00:46:30,079 absorbing differential thermal expansion between fastener and joint material for 1724 00:46:30,079 --> 00:46:30,089 between fastener and joint material for 1725 00:46:30,089 --> 00:46:32,239 between fastener and joint material for instance if you're bolding big joints 1726 00:46:32,239 --> 00:46:32,249 instance if you're bolding big joints 1727 00:46:32,249 --> 00:46:35,180 instance if you're bolding big joints with of aluminum with steel bolts so you 1728 00:46:35,180 --> 00:46:35,190 with of aluminum with steel bolts so you 1729 00:46:35,190 --> 00:46:36,529 with of aluminum with steel bolts so you have a different coefficient of 1730 00:46:36,529 --> 00:46:36,539 have a different coefficient of 1731 00:46:36,539 --> 00:46:40,209 have a different coefficient of expansion and contraction you can put 1732 00:46:40,209 --> 00:46:40,219 expansion and contraction you can put 1733 00:46:40,219 --> 00:46:43,269 expansion and contraction you can put belleville washers on to absorb 1734 00:46:43,269 --> 00:46:43,279 belleville washers on to absorb 1735 00:46:43,279 --> 00:46:47,529 belleville washers on to absorb some of this a thermal expansion to keep 1736 00:46:47,529 --> 00:46:47,539 some of this a thermal expansion to keep 1737 00:46:47,539 --> 00:46:49,839 some of this a thermal expansion to keep from overloading or under loading the 1738 00:46:49,839 --> 00:46:49,849 from overloading or under loading the 1739 00:46:49,849 --> 00:46:53,729 from overloading or under loading the joint you can use them in stacks in 1740 00:46:53,729 --> 00:46:53,739 joint you can use them in stacks in 1741 00:46:53,739 --> 00:46:57,849 joint you can use them in stacks in series or parallel in order to an in 1742 00:46:57,849 --> 00:46:57,859 series or parallel in order to an in 1743 00:46:57,859 --> 00:47:08,559 series or parallel in order to an in effect use them to become a spring now 1744 00:47:08,559 --> 00:47:08,569 effect use them to become a spring now 1745 00:47:08,569 --> 00:47:10,329 effect use them to become a spring now here's another one is that is kind of an 1746 00:47:10,329 --> 00:47:10,339 here's another one is that is kind of an 1747 00:47:10,339 --> 00:47:12,669 here's another one is that is kind of an oddball you don't see them around very 1748 00:47:12,669 --> 00:47:12,679 oddball you don't see them around very 1749 00:47:12,679 --> 00:47:14,669 oddball you don't see them around very much because they're expensive a 1750 00:47:14,669 --> 00:47:14,679 much because they're expensive a 1751 00:47:14,679 --> 00:47:17,819 much because they're expensive a self-aligning moisture you can use these 1752 00:47:17,819 --> 00:47:17,829 self-aligning moisture you can use these 1753 00:47:17,829 --> 00:47:22,359 self-aligning moisture you can use these on a structural shaped flange which is 1754 00:47:22,359 --> 00:47:22,369 on a structural shaped flange which is 1755 00:47:22,369 --> 00:47:24,689 on a structural shaped flange which is used usually has some taper to it and 1756 00:47:24,689 --> 00:47:24,699 used usually has some taper to it and 1757 00:47:24,699 --> 00:47:27,759 used usually has some taper to it and the reason they're so expensive is the 1758 00:47:27,759 --> 00:47:27,769 the reason they're so expensive is the 1759 00:47:27,769 --> 00:47:29,380 the reason they're so expensive is the washer and nut ermichine that's an 1760 00:47:29,380 --> 00:47:29,390 washer and nut ermichine that's an 1761 00:47:29,390 --> 00:47:31,179 washer and nut ermichine that's an assembly so you actually have a cone 1762 00:47:31,179 --> 00:47:31,189 assembly so you actually have a cone 1763 00:47:31,189 --> 00:47:33,669 assembly so you actually have a cone here two cousins that are rotating 1764 00:47:33,669 --> 00:47:33,679 here two cousins that are rotating 1765 00:47:33,679 --> 00:47:36,999 here two cousins that are rotating together to give you the proper 1766 00:47:36,999 --> 00:47:37,009 together to give you the proper 1767 00:47:37,009 --> 00:47:39,939 together to give you the proper alignment so that you still get axial 1768 00:47:39,939 --> 00:47:39,949 alignment so that you still get axial 1769 00:47:39,949 --> 00:47:43,929 alignment so that you still get axial loading on your boat instead of putting 1770 00:47:43,929 --> 00:47:43,939 loading on your boat instead of putting 1771 00:47:43,939 --> 00:47:46,539 loading on your boat instead of putting bending on it and this will take up to 1772 00:47:46,539 --> 00:47:46,549 bending on it and this will take up to 1773 00:47:46,549 --> 00:47:49,899 bending on it and this will take up to eight degrees maximum misalignment I 1774 00:47:49,899 --> 00:47:49,909 eight degrees maximum misalignment I 1775 00:47:49,909 --> 00:47:52,449 eight degrees maximum misalignment I don't remember now what the angle is on 1776 00:47:52,449 --> 00:47:52,459 don't remember now what the angle is on 1777 00:47:52,459 --> 00:47:55,269 don't remember now what the angle is on the i-beams and stuff like that I think 1778 00:47:55,269 --> 00:47:55,279 the i-beams and stuff like that I think 1779 00:47:55,279 --> 00:47:56,679 the i-beams and stuff like that I think it's less than that i believe it's like 1780 00:47:56,679 --> 00:47:56,689 it's less than that i believe it's like 1781 00:47:56,689 --> 00:48:00,029 it's less than that i believe it's like a 325 degree or something like that 1782 00:48:00,029 --> 00:48:00,039 a 325 degree or something like that 1783 00:48:00,039 --> 00:48:04,569 a 325 degree or something like that paper on the flange at seven now this is 1784 00:48:04,569 --> 00:48:04,579 paper on the flange at seven now this is 1785 00:48:04,579 --> 00:48:08,729 paper on the flange at seven now this is this is another one that gives you a 1786 00:48:08,729 --> 00:48:08,739 this is another one that gives you a 1787 00:48:08,739 --> 00:48:16,029 this is another one that gives you a axial reading without using a torque 1788 00:48:16,029 --> 00:48:16,039 axial reading without using a torque 1789 00:48:16,039 --> 00:48:22,719 axial reading without using a torque wrench and this is a PL PL I preload 1790 00:48:22,719 --> 00:48:22,729 wrench and this is a PL PL I preload 1791 00:48:22,729 --> 00:48:25,569 wrench and this is a PL PL I preload indicating that SPS has the patent on 1792 00:48:25,569 --> 00:48:25,579 indicating that SPS has the patent on 1793 00:48:25,579 --> 00:48:28,779 indicating that SPS has the patent on and on this one you have a regular 1794 00:48:28,779 --> 00:48:28,789 and on this one you have a regular 1795 00:48:28,789 --> 00:48:34,719 and on this one you have a regular washer a soft inner ring and then a ring 1796 00:48:34,719 --> 00:48:34,729 washer a soft inner ring and then a ring 1797 00:48:34,729 --> 00:48:36,759 washer a soft inner ring and then a ring that goes around that it has capstan 1798 00:48:36,759 --> 00:48:36,769 that goes around that it has capstan 1799 00:48:36,769 --> 00:48:39,039 that goes around that it has capstan holes in it and then a regular washer 1800 00:48:39,039 --> 00:48:39,049 holes in it and then a regular washer 1801 00:48:39,049 --> 00:48:42,519 holes in it and then a regular washer and you put all this assembly on you 1802 00:48:42,519 --> 00:48:42,529 and you put all this assembly on you 1803 00:48:42,529 --> 00:48:47,289 and you put all this assembly on you tighten it down and the this inner ring 1804 00:48:47,289 --> 00:48:47,299 tighten it down and the this inner ring 1805 00:48:47,299 --> 00:48:52,120 tighten it down and the this inner ring is actually a load cell if you will in 1806 00:48:52,120 --> 00:48:52,130 is actually a load cell if you will in 1807 00:48:52,130 --> 00:48:56,300 is actually a load cell if you will in that for a given amount of compression 1808 00:48:56,300 --> 00:48:56,310 that for a given amount of compression 1809 00:48:56,310 --> 00:48:59,840 that for a given amount of compression it has been pre calculated the amount of 1810 00:48:59,840 --> 00:48:59,850 it has been pre calculated the amount of 1811 00:48:59,850 --> 00:49:01,370 it has been pre calculated the amount of load that it takes to give you that 1812 00:49:01,370 --> 00:49:01,380 load that it takes to give you that 1813 00:49:01,380 --> 00:49:04,880 load that it takes to give you that compression so you can press it down to 1814 00:49:04,880 --> 00:49:04,890 compression so you can press it down to 1815 00:49:04,890 --> 00:49:10,010 compression so you can press it down to where this outer washer the cap span 1816 00:49:10,010 --> 00:49:10,020 where this outer washer the cap span 1817 00:49:10,020 --> 00:49:13,630 where this outer washer the cap span ring and the regular were sure are 1818 00:49:13,630 --> 00:49:13,640 ring and the regular were sure are 1819 00:49:13,640 --> 00:49:15,830 ring and the regular were sure are grinding against each other and we'll 1820 00:49:15,830 --> 00:49:15,840 grinding against each other and we'll 1821 00:49:15,840 --> 00:49:17,510 grinding against each other and we'll turn that means that this thing is 1822 00:49:17,510 --> 00:49:17,520 turn that means that this thing is 1823 00:49:17,520 --> 00:49:19,820 turn that means that this thing is compressed down to where you bottom 1824 00:49:19,820 --> 00:49:19,830 compressed down to where you bottom 1825 00:49:19,830 --> 00:49:22,760 compressed down to where you bottom doubt on this so you check the thing you 1826 00:49:22,760 --> 00:49:22,770 doubt on this so you check the thing you 1827 00:49:22,770 --> 00:49:24,830 doubt on this so you check the thing you can't turn that ring any longer you know 1828 00:49:24,830 --> 00:49:24,840 can't turn that ring any longer you know 1829 00:49:24,840 --> 00:49:26,720 can't turn that ring any longer you know you've got it to a certain axial load 1830 00:49:26,720 --> 00:49:26,730 you've got it to a certain axial load 1831 00:49:26,730 --> 00:49:29,660 you've got it to a certain axial load and they haven't color coded and 1832 00:49:29,660 --> 00:49:29,670 and they haven't color coded and 1833 00:49:29,670 --> 00:49:31,850 and they haven't color coded and available in all kinds of materials so 1834 00:49:31,850 --> 00:49:31,860 available in all kinds of materials so 1835 00:49:31,860 --> 00:49:35,750 available in all kinds of materials so that you can get them to use where you 1836 00:49:35,750 --> 00:49:35,760 that you can get them to use where you 1837 00:49:35,760 --> 00:49:37,460 that you can get them to use where you want to determine the load and there's 1838 00:49:37,460 --> 00:49:37,470 want to determine the load and there's 1839 00:49:37,470 --> 00:49:39,260 want to determine the load and there's really no good way of doing it as far as 1840 00:49:39,260 --> 00:49:39,270 really no good way of doing it as far as 1841 00:49:39,270 --> 00:49:44,210 really no good way of doing it as far as measuring it now going to inserts which 1842 00:49:44,210 --> 00:49:44,220 measuring it now going to inserts which 1843 00:49:44,220 --> 00:49:46,400 measuring it now going to inserts which is a very common thing around here in 1844 00:49:46,400 --> 00:49:46,410 is a very common thing around here in 1845 00:49:46,410 --> 00:49:51,530 is a very common thing around here in the airspace world an insert is actually 1846 00:49:51,530 --> 00:49:51,540 the airspace world an insert is actually 1847 00:49:51,540 --> 00:49:54,440 the airspace world an insert is actually it's a special bushing that's threaded 1848 00:49:54,440 --> 00:49:54,450 it's a special bushing that's threaded 1849 00:49:54,450 --> 00:49:57,020 it's a special bushing that's threaded on the inside diameter and locked with 1850 00:49:57,020 --> 00:49:57,030 on the inside diameter and locked with 1851 00:49:57,030 --> 00:49:59,510 on the inside diameter and locked with threads or protrusions or a combination 1852 00:49:59,510 --> 00:49:59,520 threads or protrusions or a combination 1853 00:49:59,520 --> 00:50:03,680 threads or protrusions or a combination on the outside diameter and installed in 1854 00:50:03,680 --> 00:50:03,690 on the outside diameter and installed in 1855 00:50:03,690 --> 00:50:07,700 on the outside diameter and installed in a drilled molded or tapped hole it's 1856 00:50:07,700 --> 00:50:07,710 a drilled molded or tapped hole it's 1857 00:50:07,710 --> 00:50:10,820 a drilled molded or tapped hole it's used to provide a strong wear resistant 1858 00:50:10,820 --> 00:50:10,830 used to provide a strong wear resistant 1859 00:50:10,830 --> 00:50:13,070 used to provide a strong wear resistant tapped hole in a softer material 1860 00:50:13,070 --> 00:50:13,080 tapped hole in a softer material 1861 00:50:13,080 --> 00:50:16,790 tapped hole in a softer material normally than the fastener and you can 1862 00:50:16,790 --> 00:50:16,800 normally than the fastener and you can 1863 00:50:16,800 --> 00:50:18,760 normally than the fastener and you can also use them to repair stripped threads 1864 00:50:18,760 --> 00:50:18,770 also use them to repair stripped threads 1865 00:50:18,770 --> 00:50:22,070 also use them to repair stripped threads where you've stripped the threads in a 1866 00:50:22,070 --> 00:50:22,080 where you've stripped the threads in a 1867 00:50:22,080 --> 00:50:24,380 where you've stripped the threads in a whole rather than going to the next 1868 00:50:24,380 --> 00:50:24,390 whole rather than going to the next 1869 00:50:24,390 --> 00:50:27,380 whole rather than going to the next bigger size in taps you can put an 1870 00:50:27,380 --> 00:50:27,390 bigger size in taps you can put an 1871 00:50:27,390 --> 00:50:31,070 bigger size in taps you can put an insert in without opening the hole up as 1872 00:50:31,070 --> 00:50:31,080 insert in without opening the hole up as 1873 00:50:31,080 --> 00:50:33,770 insert in without opening the hole up as much in fact one of the places you use 1874 00:50:33,770 --> 00:50:33,780 much in fact one of the places you use 1875 00:50:33,780 --> 00:50:38,150 much in fact one of the places you use them is when people strip the spark plug 1876 00:50:38,150 --> 00:50:38,160 them is when people strip the spark plug 1877 00:50:38,160 --> 00:50:40,910 them is when people strip the spark plug holes in aluminum engines a lot of the 1878 00:50:40,910 --> 00:50:40,920 holes in aluminum engines a lot of the 1879 00:50:40,920 --> 00:50:44,570 holes in aluminum engines a lot of the times they use in hela coil or Keynes 1880 00:50:44,570 --> 00:50:44,580 times they use in hela coil or Keynes 1881 00:50:44,580 --> 00:50:46,430 times they use in hela coil or Keynes herders and I pletely use hela coils 1882 00:50:46,430 --> 00:50:46,440 herders and I pletely use hela coils 1883 00:50:46,440 --> 00:50:49,040 herders and I pletely use hela coils most the time for that and in general 1884 00:50:49,040 --> 00:50:49,050 most the time for that and in general 1885 00:50:49,050 --> 00:50:52,730 most the time for that and in general they're the two types the one that is 1886 00:50:52,730 --> 00:50:52,740 they're the two types the one that is 1887 00:50:52,740 --> 00:50:54,740 they're the two types the one that is threaded externally and those that are 1888 00:50:54,740 --> 00:50:54,750 threaded externally and those that are 1889 00:50:54,750 --> 00:50:56,690 threaded externally and those that are locked by some method other than threads 1890 00:50:56,690 --> 00:50:56,700 locked by some method other than threads 1891 00:50:56,700 --> 00:51:00,050 locked by some method other than threads and we'll go into them and you get self 1892 00:51:00,050 --> 00:51:00,060 and we'll go into them and you get self 1893 00:51:00,060 --> 00:51:03,310 and we'll go into them and you get self tapping and all that sort of thing too 1894 00:51:03,310 --> 00:51:03,320 tapping and all that sort of thing too 1895 00:51:03,320 --> 00:51:06,110 tapping and all that sort of thing too now the earth space industry uses 1896 00:51:06,110 --> 00:51:06,120 now the earth space industry uses 1897 00:51:06,120 --> 00:51:08,060 now the earth space industry uses inserts and tapped holes and soft 1898 00:51:08,060 --> 00:51:08,070 inserts and tapped holes and soft 1899 00:51:08,070 --> 00:51:09,820 inserts and tapped holes and soft materials in order to 1900 00:51:09,820 --> 00:51:09,830 materials in order to 1901 00:51:09,830 --> 00:51:13,430 materials in order to increase the load carrying capability is 1902 00:51:13,430 --> 00:51:13,440 increase the load carrying capability is 1903 00:51:13,440 --> 00:51:16,370 increase the load carrying capability is pull out and this way you can use a 1904 00:51:16,370 --> 00:51:16,380 pull out and this way you can use a 1905 00:51:16,380 --> 00:51:18,920 pull out and this way you can use a smaller fastener and put in an insert 1906 00:51:18,920 --> 00:51:18,930 smaller fastener and put in an insert 1907 00:51:18,930 --> 00:51:22,070 smaller fastener and put in an insert and since the insert is normally about 1908 00:51:22,070 --> 00:51:22,080 and since the insert is normally about 1909 00:51:22,080 --> 00:51:23,900 and since the insert is normally about an eighth of an inch bigger in diameter 1910 00:51:23,900 --> 00:51:23,910 an eighth of an inch bigger in diameter 1911 00:51:23,910 --> 00:51:26,990 an eighth of an inch bigger in diameter than the internal thread in it you can 1912 00:51:26,990 --> 00:51:27,000 than the internal thread in it you can 1913 00:51:27,000 --> 00:51:30,410 than the internal thread in it you can take a 1032 bolt and install it in like 1914 00:51:30,410 --> 00:51:30,420 take a 1032 bolt and install it in like 1915 00:51:30,420 --> 00:51:37,750 take a 1032 bolt and install it in like an equivalent five sixteenths kept hole 1916 00:51:37,750 --> 00:51:37,760 1917 00:51:37,760 --> 00:51:41,240 here is one of the most common one and 1918 00:51:41,240 --> 00:51:41,250 here is one of the most common one and 1919 00:51:41,250 --> 00:51:44,060 here is one of the most common one and the generic name is key insert although 1920 00:51:44,060 --> 00:51:44,070 the generic name is key insert although 1921 00:51:44,070 --> 00:51:47,000 the generic name is key insert although some call them a solid threaded bushing 1922 00:51:47,000 --> 00:51:47,010 some call them a solid threaded bushing 1923 00:51:47,010 --> 00:51:52,250 some call them a solid threaded bushing or whatever and the insert we usually 1924 00:51:52,250 --> 00:51:52,260 or whatever and the insert we usually 1925 00:51:52,260 --> 00:51:56,360 or whatever and the insert we usually have external locking tangs that's these 1926 00:51:56,360 --> 00:51:56,370 have external locking tangs that's these 1927 00:51:56,370 --> 00:51:58,910 have external locking tangs that's these things you see here and when you install 1928 00:51:58,910 --> 00:51:58,920 things you see here and when you install 1929 00:51:58,920 --> 00:52:02,450 things you see here and when you install them after they're threaded in you pound 1930 00:52:02,450 --> 00:52:02,460 them after they're threaded in you pound 1931 00:52:02,460 --> 00:52:04,370 them after they're threaded in you pound those that there's a tool for pounding 1932 00:52:04,370 --> 00:52:04,380 those that there's a tool for pounding 1933 00:52:04,380 --> 00:52:07,100 those that there's a tool for pounding those down and they extend actually 1934 00:52:07,100 --> 00:52:07,110 those down and they extend actually 1935 00:52:07,110 --> 00:52:11,090 those down and they extend actually passed the threads you're the root 1936 00:52:11,090 --> 00:52:11,100 passed the threads you're the root 1937 00:52:11,100 --> 00:52:13,190 passed the threads you're the root diameter the threads to give you locking 1938 00:52:13,190 --> 00:52:13,200 diameter the threads to give you locking 1939 00:52:13,200 --> 00:52:17,120 diameter the threads to give you locking capability the the bigger diameters will 1940 00:52:17,120 --> 00:52:17,130 capability the the bigger diameters will 1941 00:52:17,130 --> 00:52:20,270 capability the the bigger diameters will have four of those on them whereas the 1942 00:52:20,270 --> 00:52:20,280 have four of those on them whereas the 1943 00:52:20,280 --> 00:52:22,190 have four of those on them whereas the smaller ones will have to and of course 1944 00:52:22,190 --> 00:52:22,200 smaller ones will have to and of course 1945 00:52:22,200 --> 00:52:23,840 smaller ones will have to and of course you can get them that are not locking at 1946 00:52:23,840 --> 00:52:23,850 you can get them that are not locking at 1947 00:52:23,850 --> 00:52:26,000 you can get them that are not locking at all that you use some other method of 1948 00:52:26,000 --> 00:52:26,010 all that you use some other method of 1949 00:52:26,010 --> 00:52:28,630 all that you use some other method of triangle up the external thread on them 1950 00:52:28,630 --> 00:52:28,640 triangle up the external thread on them 1951 00:52:28,640 --> 00:52:32,090 triangle up the external thread on them now they are very labor-intensive to 1952 00:52:32,090 --> 00:52:32,100 now they are very labor-intensive to 1953 00:52:32,100 --> 00:52:34,640 now they are very labor-intensive to install so you don't install them unless 1954 00:52:34,640 --> 00:52:34,650 install so you don't install them unless 1955 00:52:34,650 --> 00:52:38,690 install so you don't install them unless you have to here is the other type the 1956 00:52:38,690 --> 00:52:38,700 you have to here is the other type the 1957 00:52:38,700 --> 00:52:42,710 you have to here is the other type the Gila coil which is I believe now owned 1958 00:52:42,710 --> 00:52:42,720 Gila coil which is I believe now owned 1959 00:52:42,720 --> 00:52:47,690 Gila coil which is I believe now owned by Black & Decker i think is the owner 1960 00:52:47,690 --> 00:52:47,700 by Black & Decker i think is the owner 1961 00:52:47,700 --> 00:52:50,060 by Black & Decker i think is the owner of the patent but they're also called a 1962 00:52:50,060 --> 00:52:50,070 of the patent but they're also called a 1963 00:52:50,070 --> 00:52:55,220 of the patent but they're also called a wire thread and it's usually made of 1964 00:52:55,220 --> 00:52:55,230 wire thread and it's usually made of 1965 00:52:55,230 --> 00:52:57,230 wire thread and it's usually made of stainless steel and has a diamond-shaped 1966 00:52:57,230 --> 00:52:57,240 stainless steel and has a diamond-shaped 1967 00:52:57,240 --> 00:53:01,570 stainless steel and has a diamond-shaped cross section that will actually form 1968 00:53:01,570 --> 00:53:01,580 cross section that will actually form 1969 00:53:01,580 --> 00:53:03,890 cross section that will actually form internal and external threads when 1970 00:53:03,890 --> 00:53:03,900 internal and external threads when 1971 00:53:03,900 --> 00:53:06,110 internal and external threads when install and it's like like taking a 1972 00:53:06,110 --> 00:53:06,120 install and it's like like taking a 1973 00:53:06,120 --> 00:53:07,910 install and it's like like taking a spring if you will and winding it down 1974 00:53:07,910 --> 00:53:07,920 spring if you will and winding it down 1975 00:53:07,920 --> 00:53:10,280 spring if you will and winding it down into a hole and the Diamonds section 1976 00:53:10,280 --> 00:53:10,290 into a hole and the Diamonds section 1977 00:53:10,290 --> 00:53:12,110 into a hole and the Diamonds section part on the back goes into the existing 1978 00:53:12,110 --> 00:53:12,120 part on the back goes into the existing 1979 00:53:12,120 --> 00:53:14,410 part on the back goes into the existing threads and then the diamond section on 1980 00:53:14,410 --> 00:53:14,420 threads and then the diamond section on 1981 00:53:14,420 --> 00:53:17,930 threads and then the diamond section on the inside is your thread diameter that 1982 00:53:17,930 --> 00:53:17,940 the inside is your thread diameter that 1983 00:53:17,940 --> 00:53:20,330 the inside is your thread diameter that you put your fastener in now they're 1984 00:53:20,330 --> 00:53:20,340 you put your fastener in now they're 1985 00:53:20,340 --> 00:53:23,059 you put your fastener in now they're usually coated to deter her 1986 00:53:23,059 --> 00:53:23,069 usually coated to deter her 1987 00:53:23,069 --> 00:53:26,269 usually coated to deter her ocean and seizing and you can get them 1988 00:53:26,269 --> 00:53:26,279 ocean and seizing and you can get them 1989 00:53:26,279 --> 00:53:28,640 ocean and seizing and you can get them both in locking and unlocking you see if 1990 00:53:28,640 --> 00:53:28,650 both in locking and unlocking you see if 1991 00:53:28,650 --> 00:53:30,380 both in locking and unlocking you see if you look at this this is the non locking 1992 00:53:30,380 --> 00:53:30,390 you look at this this is the non locking 1993 00:53:30,390 --> 00:53:32,660 you look at this this is the non locking here and this is a locking you actually 1994 00:53:32,660 --> 00:53:32,670 here and this is a locking you actually 1995 00:53:32,670 --> 00:53:34,969 here and this is a locking you actually have some deform coils down in here in 1996 00:53:34,969 --> 00:53:34,979 have some deform coils down in here in 1997 00:53:34,979 --> 00:53:38,569 have some deform coils down in here in this installment Tang which you may not 1998 00:53:38,569 --> 00:53:38,579 this installment Tang which you may not 1999 00:53:38,579 --> 00:53:40,459 this installment Tang which you may not may or may not be able to see on here 2000 00:53:40,459 --> 00:53:40,469 may or may not be able to see on here 2001 00:53:40,469 --> 00:53:42,769 may or may not be able to see on here it's broken off after installation now 2002 00:53:42,769 --> 00:53:42,779 it's broken off after installation now 2003 00:53:42,779 --> 00:53:46,969 it's broken off after installation now well the the difference between the Gila 2004 00:53:46,969 --> 00:53:46,979 well the the difference between the Gila 2005 00:53:46,979 --> 00:53:50,749 well the the difference between the Gila coil and the key insert the Keen cert is 2006 00:53:50,749 --> 00:53:50,759 coil and the key insert the Keen cert is 2007 00:53:50,759 --> 00:53:57,130 coil and the key insert the Keen cert is only available in one length for a size 2008 00:53:57,130 --> 00:53:57,140 only available in one length for a size 2009 00:53:57,140 --> 00:54:00,380 only available in one length for a size the Gila coils you can get them in 2010 00:54:00,380 --> 00:54:00,390 the Gila coils you can get them in 2011 00:54:00,390 --> 00:54:02,779 the Gila coils you can get them in different lengths you can get them up to 2012 00:54:02,779 --> 00:54:02,789 different lengths you can get them up to 2013 00:54:02,789 --> 00:54:06,589 different lengths you can get them up to from 1 D 2 3 D length where D is the 2014 00:54:06,589 --> 00:54:06,599 from 1 D 2 3 D length where D is the 2015 00:54:06,599 --> 00:54:10,309 from 1 D 2 3 D length where D is the diameter of the fastener and another 2016 00:54:10,309 --> 00:54:10,319 diameter of the fastener and another 2017 00:54:10,319 --> 00:54:12,799 diameter of the fastener and another thing of course you need a to open the 2018 00:54:12,799 --> 00:54:12,809 thing of course you need a to open the 2019 00:54:12,809 --> 00:54:16,849 thing of course you need a to open the hole up less where you put a Gila coil 2020 00:54:16,849 --> 00:54:16,859 hole up less where you put a Gila coil 2021 00:54:16,859 --> 00:54:19,219 hole up less where you put a Gila coil in so if you're repairing stripped 2022 00:54:19,219 --> 00:54:19,229 in so if you're repairing stripped 2023 00:54:19,229 --> 00:54:21,949 in so if you're repairing stripped threads in an area where you don't have 2024 00:54:21,949 --> 00:54:21,959 threads in an area where you don't have 2025 00:54:21,959 --> 00:54:27,099 threads in an area where you don't have a lot of room you can recap the whole 2026 00:54:27,099 --> 00:54:27,109 a lot of room you can recap the whole 2027 00:54:27,109 --> 00:54:30,620 a lot of room you can recap the whole just slightly and get it opened up 2028 00:54:30,620 --> 00:54:30,630 just slightly and get it opened up 2029 00:54:30,630 --> 00:54:32,269 just slightly and get it opened up enough that you can put a Gila coil in 2030 00:54:32,269 --> 00:54:32,279 enough that you can put a Gila coil in 2031 00:54:32,279 --> 00:54:40,870 enough that you can put a Gila coil in it 2032 00:54:40,870 --> 00:54:40,880 2033 00:54:40,880 --> 00:54:45,799 here's a kind of a more rare tape this 2034 00:54:45,799 --> 00:54:45,809 here's a kind of a more rare tape this 2035 00:54:45,809 --> 00:54:53,269 here's a kind of a more rare tape this is a locking tape insert in which you 2036 00:54:53,269 --> 00:54:53,279 is a locking tape insert in which you 2037 00:54:53,279 --> 00:54:57,980 is a locking tape insert in which you have the split beam nut machined on the 2038 00:54:57,980 --> 00:54:57,990 have the split beam nut machined on the 2039 00:54:57,990 --> 00:55:00,529 have the split beam nut machined on the bottom of it remember I showed you the 2040 00:55:00,529 --> 00:55:00,539 bottom of it remember I showed you the 2041 00:55:00,539 --> 00:55:05,599 bottom of it remember I showed you the slip split beam lock nut earlier and so 2042 00:55:05,599 --> 00:55:05,609 slip split beam lock nut earlier and so 2043 00:55:05,609 --> 00:55:08,749 slip split beam lock nut earlier and so that you have the locking capability but 2044 00:55:08,749 --> 00:55:08,759 that you have the locking capability but 2045 00:55:08,759 --> 00:55:12,470 that you have the locking capability but of course you are have a longer insert 2046 00:55:12,470 --> 00:55:12,480 of course you are have a longer insert 2047 00:55:12,480 --> 00:55:14,269 of course you are have a longer insert because of this thing having to be 2048 00:55:14,269 --> 00:55:14,279 because of this thing having to be 2049 00:55:14,279 --> 00:55:16,039 because of this thing having to be installed because this is not threaded 2050 00:55:16,039 --> 00:55:16,049 installed because this is not threaded 2051 00:55:16,049 --> 00:55:19,460 installed because this is not threaded into the hole and these are made 2052 00:55:19,460 --> 00:55:19,470 into the hole and these are made 2053 00:55:19,470 --> 00:55:22,220 into the hole and these are made primarily for aerospace usage out of 2054 00:55:22,220 --> 00:55:22,230 primarily for aerospace usage out of 2055 00:55:22,230 --> 00:55:24,319 primarily for aerospace usage out of either eight to eighty six or inconel 2056 00:55:24,319 --> 00:55:24,329 either eight to eighty six or inconel 2057 00:55:24,329 --> 00:55:29,029 either eight to eighty six or inconel 718 and since you have less external 2058 00:55:29,029 --> 00:55:29,039 718 and since you have less external 2059 00:55:29,039 --> 00:55:31,609 718 and since you have less external thread you have to be careful in soft 2060 00:55:31,609 --> 00:55:31,619 thread you have to be careful in soft 2061 00:55:31,619 --> 00:55:33,859 thread you have to be careful in soft materials to make sure that you don't 2062 00:55:33,859 --> 00:55:33,869 materials to make sure that you don't 2063 00:55:33,869 --> 00:55:36,380 materials to make sure that you don't exceed the pullout allowable when you 2064 00:55:36,380 --> 00:55:36,390 exceed the pullout allowable when you 2065 00:55:36,390 --> 00:55:39,799 exceed the pullout allowable when you install a bolt in them because the 2066 00:55:39,799 --> 00:55:39,809 install a bolt in them because the 2067 00:55:39,809 --> 00:55:42,200 install a bolt in them because the because of the split beam increasing the 2068 00:55:42,200 --> 00:55:42,210 because of the split beam increasing the 2069 00:55:42,210 --> 00:55:46,880 because of the split beam increasing the overall length and here is one that 2070 00:55:46,880 --> 00:55:46,890 overall length and here is one that 2071 00:55:46,890 --> 00:55:51,499 overall length and here is one that solves some problems but it also creates 2072 00:55:51,499 --> 00:55:51,509 solves some problems but it also creates 2073 00:55:51,509 --> 00:55:55,640 solves some problems but it also creates some others the floating insert of 2074 00:55:55,640 --> 00:55:55,650 some others the floating insert of 2075 00:55:55,650 --> 00:55:58,099 some others the floating insert of course if you're using and i'll be 2076 00:55:58,099 --> 00:55:58,109 course if you're using and i'll be 2077 00:55:58,109 --> 00:56:00,529 course if you're using and i'll be covering us later on with if you're 2078 00:56:00,529 --> 00:56:00,539 covering us later on with if you're 2079 00:56:00,539 --> 00:56:02,589 covering us later on with if you're using counter sunk or flathead fasteners 2080 00:56:02,589 --> 00:56:02,599 using counter sunk or flathead fasteners 2081 00:56:02,599 --> 00:56:07,269 using counter sunk or flathead fasteners the countersink tries to sulfa line 2082 00:56:07,269 --> 00:56:07,279 the countersink tries to sulfa line 2083 00:56:07,279 --> 00:56:11,089 the countersink tries to sulfa line fastener if you're going into a rigid 2084 00:56:11,089 --> 00:56:11,099 fastener if you're going into a rigid 2085 00:56:11,099 --> 00:56:13,279 fastener if you're going into a rigid pepto now you have the two of them 2086 00:56:13,279 --> 00:56:13,289 pepto now you have the two of them 2087 00:56:13,289 --> 00:56:15,230 pepto now you have the two of them working against each other which is not 2088 00:56:15,230 --> 00:56:15,240 working against each other which is not 2089 00:56:15,240 --> 00:56:17,509 working against each other which is not too good well this solves that problem 2090 00:56:17,509 --> 00:56:17,519 too good well this solves that problem 2091 00:56:17,519 --> 00:56:21,470 too good well this solves that problem in that the insert is in you have 2092 00:56:21,470 --> 00:56:21,480 in that the insert is in you have 2093 00:56:21,480 --> 00:56:23,990 in that the insert is in you have actually an insert in the bottom of this 2094 00:56:23,990 --> 00:56:24,000 actually an insert in the bottom of this 2095 00:56:24,000 --> 00:56:25,999 actually an insert in the bottom of this one so that it's externally threaded 2096 00:56:25,999 --> 00:56:26,009 one so that it's externally threaded 2097 00:56:26,009 --> 00:56:28,819 one so that it's externally threaded just like the regular teen cert then you 2098 00:56:28,819 --> 00:56:28,829 just like the regular teen cert then you 2099 00:56:28,829 --> 00:56:30,710 just like the regular teen cert then you have this little jobby that floats down 2100 00:56:30,710 --> 00:56:30,720 have this little jobby that floats down 2101 00:56:30,720 --> 00:56:35,089 have this little jobby that floats down in here and so this will give you some 2102 00:56:35,089 --> 00:56:35,099 in here and so this will give you some 2103 00:56:35,099 --> 00:56:38,630 in here and so this will give you some self-alignment when when using 2104 00:56:38,630 --> 00:56:38,640 self-alignment when when using 2105 00:56:38,640 --> 00:56:43,190 self-alignment when when using countersunk fasteners but by putting all 2106 00:56:43,190 --> 00:56:43,200 countersunk fasteners but by putting all 2107 00:56:43,200 --> 00:56:46,130 countersunk fasteners but by putting all of this in it it since this has to float 2108 00:56:46,130 --> 00:56:46,140 of this in it it since this has to float 2109 00:56:46,140 --> 00:56:50,839 of this in it it since this has to float inside the main king cert you have a 2110 00:56:50,839 --> 00:56:50,849 inside the main king cert you have a 2111 00:56:50,849 --> 00:56:53,629 inside the main king cert you have a smaller diameter 2112 00:56:53,629 --> 00:56:53,639 smaller diameter 2113 00:56:53,639 --> 00:56:57,649 smaller diameter internally for a given diameter 2114 00:56:57,649 --> 00:56:57,659 internally for a given diameter 2115 00:56:57,659 --> 00:57:00,239 internally for a given diameter externally so therefore you're losing 2116 00:57:00,239 --> 00:57:00,249 externally so therefore you're losing 2117 00:57:00,249 --> 00:57:04,199 externally so therefore you're losing some to put that floating capability in 2118 00:57:04,199 --> 00:57:04,209 some to put that floating capability in 2119 00:57:04,209 --> 00:57:07,049 some to put that floating capability in you're losing some so you might wind up 2120 00:57:07,049 --> 00:57:07,059 you're losing some so you might wind up 2121 00:57:07,059 --> 00:57:10,939 you're losing some so you might wind up having to go to a larger diameter insert 2122 00:57:10,939 --> 00:57:10,949 having to go to a larger diameter insert 2123 00:57:10,949 --> 00:57:13,919 having to go to a larger diameter insert externally then you nor normally would 2124 00:57:13,919 --> 00:57:13,929 externally then you nor normally would 2125 00:57:13,929 --> 00:57:18,709 externally then you nor normally would use now here's the self-tapping inserts 2126 00:57:18,709 --> 00:57:18,719 use now here's the self-tapping inserts 2127 00:57:18,719 --> 00:57:22,169 use now here's the self-tapping inserts this is usually a self or so solid 2128 00:57:22,169 --> 00:57:22,179 this is usually a self or so solid 2129 00:57:22,179 --> 00:57:24,749 this is usually a self or so solid bushing with either tapered external 2130 00:57:24,749 --> 00:57:24,759 bushing with either tapered external 2131 00:57:24,759 --> 00:57:27,089 bushing with either tapered external threads like a self-tapping screw like 2132 00:57:27,089 --> 00:57:27,099 threads like a self-tapping screw like 2133 00:57:27,099 --> 00:57:31,379 threads like a self-tapping screw like this or you can have and you can have 2134 00:57:31,379 --> 00:57:31,389 this or you can have and you can have 2135 00:57:31,389 --> 00:57:35,519 this or you can have and you can have them also solid with a nighlok pelletier 2136 00:57:35,519 --> 00:57:35,529 them also solid with a nighlok pelletier 2137 00:57:35,529 --> 00:57:39,539 them also solid with a nighlok pelletier for locking them or you can have one 2138 00:57:39,539 --> 00:57:39,549 for locking them or you can have one 2139 00:57:39,549 --> 00:57:42,479 for locking them or you can have one that they use in plastic quite a bit 2140 00:57:42,479 --> 00:57:42,489 that they use in plastic quite a bit 2141 00:57:42,489 --> 00:57:45,929 that they use in plastic quite a bit what they call a speed cert and this is 2142 00:57:45,929 --> 00:57:45,939 what they call a speed cert and this is 2143 00:57:45,939 --> 00:57:50,299 what they call a speed cert and this is used I think for like in electrical 2144 00:57:50,299 --> 00:57:50,309 used I think for like in electrical 2145 00:57:50,309 --> 00:57:53,119 used I think for like in electrical circuit boards and stuff like that it 2146 00:57:53,119 --> 00:57:53,129 circuit boards and stuff like that it 2147 00:57:53,129 --> 00:57:58,459 circuit boards and stuff like that it you drill a hole and you actually can 2148 00:57:58,459 --> 00:57:58,469 you drill a hole and you actually can 2149 00:57:58,469 --> 00:58:03,509 you drill a hole and you actually can push self tap the thing by deforming the 2150 00:58:03,509 --> 00:58:03,519 push self tap the thing by deforming the 2151 00:58:03,519 --> 00:58:07,699 push self tap the thing by deforming the plastic without generating any shavings 2152 00:58:07,699 --> 00:58:07,709 plastic without generating any shavings 2153 00:58:07,709 --> 00:58:14,759 plastic without generating any shavings so we will continue next with the Sun 2154 00:58:14,759 --> 00:58:14,769 so we will continue next with the Sun 2155 00:58:14,769 --> 00:58:18,029 so we will continue next with the Sun threaded insert so we'll take a break 2156 00:58:18,029 --> 00:58:18,039 threaded insert so we'll take a break 2157 00:58:18,039 --> 00:58:20,519 threaded insert so we'll take a break but right now
