i know that this has been addressed many times but the answer "left me". what is the proper way to remove a tight 3 jaw from my south bend threaded spindle. just got done fitting a backplate to a new bison chuck and the only way that I could remove it was to put an aluminum bar 1 in. by 1/2 in between the jaws and smack it with a nylon mallet. I didn't jam it on tight when installing it. I wasn't cutting anything. I was setting it for runout with the bolts not tightened but lightly. I ended up with about .004 total runout. would greasing the threads help? also would rapping on the chuck with a rubber mallet be ok? advice??
