Wow!!...great Tip.
Made me think!
heres a another thing I have never saw before...my Brother was heating up a Ford ball joint on a mid 90's to remove it, he heated it and hit it with his air hammer to drive it out the grease was oozin out and smokin ...it was pretty rusty ..and did not move ...so he put he heat to it again well the action of the previous air hammer motion had made a seal in the boilin, smokin grease in the ball joint an BOOM like a shotgun the stud & ball was fired out of the balljoint with enough force to take a big chip outta the concrete floor and launch it up through the roof of his shop!!!...it was pretty scary as I FELT THE RUSHING AIR OF THE PROJECTILE GO PAST MY HEAD!!!
Be careful of the HEAT WRENCH folks!
