Skeptical of I could make this welding / copper tube trick work. I thought it was worth sharing because I never thought of it before. This guy has some good ideas on occasion.
I have never personally tried this but had a number of oldtimers tell me this. Cherry the broken bolt with your torch and then stick a candle to it until it cools. Then the bolt will come out like it was never seized. Any oldtimers on here that can confirm this theory?
that does work but you must let the bolt cool some otherwise it burns the wax to quicklyI have never personally tried this but had a number of oldtimers tell me this.

Someone got to the top studs on this 3406 with a drill and no guide. I was able to weld the bottom ones out first crack. The drilled one is almost a full hole off ,beyond helicoil . Any ideas? View attachment 233660 View attachment 233661 View attachment 233662
Maybe I missed the post but I didn’t see anyone mention the mini right angle die grinder. Looks like a dentist drill. I drill the broken bolt as large as I can without hitting the threads and then use the grinder to cut 3-4 grooves as close to the threads as I can and knock out the pieces with a tiny punch or screwdriver. I also use many of the methods that you guys do but I like to have as many tools in my arsenal as I can. I may be weird but I almost enjoy removing broken bolts. Nothing like a good challenge!
