TIGHTCHOKE Posted March 5, 2017 Report Share Posted March 5, 2017 Simon, which make of bolt extractor will you be using? Quote Link to comment Share on other sites More sharing options...
ditchman Posted March 5, 2017 Author Report Share Posted March 5, 2017 Simon, which make of bolt extractor will you be using? wont be using bolt extractor......i will progressivly drill it out as much as i dare then make something out of an old chainsaw file and fold it in on itself..........not rocket science....its what you did before bolt extactors..............the thing is with all this heat it has rust welded its self to the threads....so spinning it out with an extractor might not work without heat...........if you do add localised heat to the casting..........it will crack....and this is a very good casting ....i dont want to scrap it...

figgy Posted March 5, 2017 Report Share Posted March 5, 2017 I've always drilled out then re tapped the hole thus removing the old thread that was stuck in. Looking forward to seeing your drilling out then folding in of the threads technique. Quote Link to comment Share on other sites More sharing options...

Looking forward to seeing your drilling out then folding in of the threads technique. Doing it your way there is a chance of the tap squeezing the old thread of the bolt into the thread of the hole and damaging it. His way is less chance of damage but his drilling must be spot on.

ditchman Posted March 5, 2017 Author Report Share Posted March 5, 2017 ive been fiddling........................not good ...it isnt working as i thought...........ive got a mate coming over tomorrow to give me a hand........have drilled the bolt out....christ it was hard had to sharpen the bits 4 times.....the bolt is so hi-tensile it wont fold like it should...so i am going onto plan B.....give that a try......then plan C....which is the option i dont want to go to........... everything is a learning curve...................

bornfree Posted March 5, 2017 Report Share Posted March 5, 2017 Now about a quick heat up with a no3 oxy acetylene welding nozzle and a reducing flame to anneal the remainder of the bolt without putting to much heat into the casting.

figgy Posted March 6, 2017 Report Share Posted March 6, 2017 It was the only way on high temp steam fittings with the same rusting issues. The odd time if you knew it was more or less certain to snap drilling a hole through the bolt before trying to remove could ease its removal. Hope it comes out ok.

Hope it comes out ok. the only way im going to get it out is the way you suggested.....what scuppered me was the very very high tensile bolts that are used...im just waiting for my mate to turn up tomorrow with a good quality extractor....then we will get started....need to take it easy as i am not going to bre4ak the casting....the rebuild pack @ £38.00 delivered next day is on hold....quite a good pack as it contains all new studs and bolts and ALL the internals 'cept the shaft and turbines........... i will let you no the state of play tomorrow.....................
