EngineerEli Posted September 13, 2015 Share Posted September 13, 2015 So this is not my first tanfo, but the set screw on my new stock II, is being really stubborn. I have a new dawson coming and I figures I would get the one one out ahead of time. At first try I rounded out the allen wrench. So I tried taking my heat gun to it. Heated till I saw stiff bubbling out of the dove tail and around the set screw. Then tried again after using a cut off wheel on the dremmel to freshen up the allen, and rounded it off again. I re heated, and tried applying clp oil hot and cold, still want go... I'm inclined to just drill the suckered out, but before I do does anyone have any last ideas to try? -Eli Link to comment Share on other sites More sharing options...
Open1215 Posted September 13, 2015 Share Posted September 13, 2015 This is going to sound stupid, but only bit of advice would be to try tightening it first and then back it out. Whenever I have rusted in bolts on a bike I would tighten it first and put as much force as I could on it and then they would generally break right loose. Also PB Blaster, but if you're using oil issue do the same trick. If all else fails drill it sorry Link to comment Share on other sites More sharing options...
EngineerEli Posted September 13, 2015 Author Share Posted September 13, 2015 Thought about the pb blaster but I'm out at the moment. The thing though is its not rust, it's loctite. But now after all the heat I've put into it. Got it to smoke, there shouldn't be much left to the loctite. How long should it take to burn out, I had the heat gun on it on high for about 2 min. Could I have to go longer? Link to comment Share on other sites More sharing options...
Open1215 Posted September 13, 2015 Share Posted September 13, 2015 Hmm. One option is if you have a wood burner. Only heat the screw. Only the threads will heat up N melt the loctight. with heat guns everything can expand, holding the screw tighter. Put a fine tip in the hex hole and let it sit for 45 sec or till smoke pops up. Then try to turn clockwise just to apply medium pressure. Then back out. Link to comment Share on other sites More sharing options...
bayougump Posted September 13, 2015 Share Posted September 13, 2015 I drilled one out today ironically. I couldn't get it out and finally had enough and drilled on it and used a punch and mallet to pop it off. Link to comment Share on other sites More sharing options...
EngineerEli Posted September 13, 2015 Author Share Posted September 13, 2015 Drilled it... After that the sight came off with relative ease. Link to comment Share on other sites More sharing options...
johnbu Posted September 13, 2015 Share Posted September 13, 2015 That loctite red is strong stuff. You were waaaay short on temp. 500f for 2 minutes, disassemble while above 500f. Link to comment Share on other sites More sharing options...
