Just another idea to pass on:
I had been using a drill like that for a slicker, I just had a wooden thread spool with a bolt running through it. It was a pain to control so I found a 1/2" chuck at home depot that attached to an electric motor I had laying around. After chucking on a large, round, hard wood drawer pull, I mounted it to the work bench. It is much easier to slick edges now because I can use both hands for control.
