bench grinder problems HELP!!!

Wait a sec. You said this thing purrs like a kitten? Is that with the stone wheels attached? If so, the wire wheels are way out of balance and I wouldn't use them as they would most likely damage the bearings after a lot of use. If it danced with the stones they might also be out of balance.

I mounted my grinder to a piece of 2x10 and use clamps to hold it to the workbench. When I am done with it I can unclamp and sit it under the bench out of the way. I hadn't thought about using a rubber pad, but it almost seems like it has rubber feet - I don't remember. Been a long time.
