(can I post about bench grinders here?)
So I was dinking around with the 8" craftsman yesterday. I was trimming down some bolts for the
step-son's cycle, and there's an annoying problem. (probably operator error, loose nut at the end of the bolt...)
I have dressed both wheels but when the piece part is placed against the wheel it like bounces off.
Does that make sense? I put the bolt (~Ø6mm) in a 3/8" 'pin vise' and when I went to twirl it against the wheel it does a bumpity-bump-bump action.
I can't do it smoothly either free hand or on the tool rest.
First thing I'm thinking is that the wheels are badly out of round, and I'm not sure how to correct that.
Second thing, I got to looking at the design. I will have to redo the tools rests. The wheel housing mounted to the motor is stamped steel instead of the old time cast housing style.
Not enough mass and dampening effect perhaps. Looking at DanS's Baldor write up, that design has quite a bit more mass - heftier.
