I've had a Baldor 110/230, extended shafts, ball bearings, 3/4" shafts, as I recall its 3/4 hp, for 10 years. I've run it on 110 all these years, buffed out stainless shells, headlight, tail lights and even buffed out a airplane radial stainless exhaust for a friend. I've had no problems other than installing new pads. Using good buffing compound seems to give better results. I have it installed on a pedistol stand, with a big base, so I can move it around. One of the better investments I've made.
