Has anyone heard of using an oxy/acetylene torch to burn out a broken off thread tap in a blind hole?
Yesterday I snapped a 5/8" bottom tap off 30mm down a blind hole in some 316. I was aware of broken tap removal tools and all the other methods/theories for getting the broken piece out, but never heard the above.
Gave it a go as other options weren't really viable. And what do you know it fkn worked.
Using a standard brazing tip you jam that sucker in the hole and heat up just the tap until yellow then slowly turn the acetylene off and watch the tap just blow away in a shit tonne of sparks and oxygen
