i do the same as you do chipmunk i keep turning that thing until my wrist is sore then i switch hands. maybe my probsbly with the bigger bits is the diameter thing next time i will grind it done on the bench grinder first. easy enough now that the company i work for threw out my new dewalt bench grinder. something about osha. so they bought a 1500 dollar disc/belt sander for us to use. all i had to do is pickit up out of the garbage can. great deal for me as it was only 6 months old. later MO
