A...Yeah, I've never had luck with them either. And I can't tell you how many drill bits I've broken trying to drill the holes for them. I've wanted to try reverse twist bits, but I haven't found any yet.<br /><br />As for the bolt in question--when all else failed, I ground the head off! Leaving the bottom behind wasn't a problem in this case.<br /><br />Actually, I discovered another use for a nut splitter last night. One of the nuts holding the tub down wouldn't hold a socket or wrench, and the harder I tried, the worse it got. So I decided to use a nut splitter on it. But once I got the splitter firmly engaged, I realized that that would hold the nut nicely. Since it was in a confined area, the splitter couldn't spin. So I put the socket back on the bolt and unscrewed it successfully!<br /><br />BTW, I recently saw a study that showed that the best penetrating oil (at least for loosening rusted fasteners) is a 50/50 mix of acetone and ATF. Haven't tried it yet, but I'm sure I will on this project at some point. Everything I've done so far is somewhere I don't give a darn if the bolt broke off (and I've sheared a bunch).<br /><br />But you broke your hand!? And went right back to finish the job within three days!?Paul S.https://www.blogger.com/profile/01983447116122253943noreply@blogger.comtag:blogger.com,1999:blog-4239108880907411993.post-44940231465136056142013-04-26T14:19:12.609-06:002013-04-26T14:19:12.609-06:00Hey, I never had much luck with those screw extrac...Hey, I never had much luck with those screw extractors, but a set of reverse twist drill bits has worked for me many times. If it's a bigger bolt that's sheared off and stuck, I've drilled a hole down it, pounded in a 1/4 inch phillips bit, and then used a 1/4 " wrench to turn it out. The crankshaft bolt on my old Hawaiian Mitsubishi ute took 3 days, a broken hand, and a wrench twisted into a spiral, but it eventually came out. Lots of penetrating oil and leaving it for tomorrow helps too.Wade Bortzhttps://www.blogger.com/profile/10975115541719442270noreply@blogger.com
