Brent, what kind of rpm do you use with the shrinking disc. i've been trying to use one on my electric buffer but i don't think it's got enough rpm to get the metal hot.

Russ b, my brother in law uses his stud gun to shrink metal in the same fashion. he heats up a small spot and then uses a hammer dolly working around the hot spot in a circle fashion working in toward the heated area, kinda pushing the metal into the heated area.
