ke-off bolts, and you have try everything???

This may help you.

3 different techniques that all have there place...

Com: Wayne miller :I was told by a wise man, never focus heat on the broken fastener, focus heat around it,

you don't want the fastener to expand you want the female threads to expand.

Females like lubrication as well. Seems French Canadian to me.

Com: Skipper : here is another trick to you from an old timer;;; on everything car truck tractor everything,

i allways spray paint both stud and hole before in screw m. even if i just painted it and took it out a minute ago. paint both again.

it will screw easyer and 3 years later it will come out like yesterday.

[ helps stop electrolises and rust and still be there like a coating so threads slide easyer.]

a dollar for cheap spray can paint works fantastic.

Com: Ross Charlie : Well sir you got my attention to the point of me subscribing.

Impressed not by just what you've done .but your commentary too .

One of the few I've heard separating the wheat from the chaff in you know what I mean   Darren UK..

Com: goolymolly : Good job. Have you tried to use the punch to knock it out after you heat it orange before torching it out?

I've tried that a few times it worked good...
