thecelticforge Posted September 9, 2009 Share Posted September 9, 2009 I have had a bad month with our automobiles. The truck broke a mounting bolt for the brake caliper. I was able to drill and tap it out! However, the threads in the spindle were buggered up. I soon discovered that the threads had an odd pitch and there was no thread repair on the market. So I bought new bolts and put one in the fire and then hardened the threads. It fixed the old ones as pretty as you please. I plan on using this method again and again when ever I can!

gaylan veater Posted September 9, 2009 Share Posted September 9, 2009 Thanks for sharing your experience. I cant tell you how many times I have used my blacksmithing skills in my everyday work as a auto mechanic. All the other guys in the shop come to me when they cant get a part and I usually can repair or make what they cant find, As long as it is out of steel HEE HEE.

double_edge2 Posted September 9, 2009 Share Posted September 9, 2009 awesome, nice to hear success. i agree , even if you only did the mod and repair of brackets, it makes a forge an almost essential tool. apart from 5 or 8mm steel (using an ally back plate, fill weld redrill and tap or similar with a rivet and forge weld to fill), ive only ever done the deep chaser thread thing with ally, and only once, didnt want to test it just left it and sneak away.....lol. did try the ally fill thing to fix up a thread gone wrong, i was trying to repair my imatience...re drilled, patiently cleaned and drilled the little holes so the new slug would bite and hold, poured, redrilled, tapped, then it let go..:mad: Quote Link to comment Share on other sites More sharing options...

Well done, sir! Now, perhaps you'll give Kipling his due and provide a byline... ;) Quote Link to comment Share on other sites More sharing options...
Frosty Posted September 19, 2009 Share Posted September 19, 2009 Next time file or grind a groove through the threads the length of the bolt. It will become relief so it will cut the threads more reliably and cleanly. Frosty Quote Link to comment Share on other sites More sharing options...
