Works great for bearings, so why not? Thing about heating bearings for installation.. ya gotta get them on FAST 'cause soon as the shaft pulls the heat out of 'em, they shrink back down.

I agree with heating or cooling metal to get it to do what you want it to do, do it all the time, but putting a 20 lb. HB in a pan of boiling water is not gonna do nothing. if it did by the time you get from the house to the garage it wouldnt do no good. you are talking about a lot of metal. it would take a torch to make a dif.
