I found an Emerson Electric Manufacturing co motor with Sears and roebuck 1/2 in arbors on it for $20 at a garage sale. It had a wire brush and buffer wheel on it. So quiet, plenty powerfull, lots of torque for an old motor. Ran an add on next door for a wood Turner and got a pretty decent burnisher with 5/8, 1/2, and so on done in maple for a $40 donation to a local charity. 1750 rpm, works fine.
