Following Robo Hippy's advice I purchased a couple of Milwaukee close quarter drill motors and some sanding products from Woodturners Wonders. The combination seems to work very well, at least from the standpoint of my relatively inexperienced hands. A couple of days ago I used the purple discs for some small sanding tasks and found them to be just as useful alone without the drill motor. Coincidentally, I received a special offer yesterday from Woodturners Wonders for 400 additional purple discs at what seemed like a good price, So I bought them along with a hand sanding pad thinking that I would probably use more of them for that purpose. Anyone else using these small sanding discs for hand sanding instead of cutting pieces from large sheets of sanding paper?
