The torch only melts the steel threads. Its a nerve wracking job but works well for me.

Purdy,
NOT recommending this, But I've seen my friend, Ron, BLOW a 1/2" broken stud from a block, without even drilling, with a light duty cutting torch & the threads were left intact, with only a few tiny dingle berries left, that were removed easily with a pick! Cleaned the threads with a bottoming tap, & PERFECT!!
AGAIN, I DON'T GENERALLY RECOMMEND THIS FOR THE NOVICE OR THE FAINT OF HEART!! Ron's had years of experience doin' this!-----Bill W.
