I find that if I use a mop in my drill press first, there is very little more clean up needed. CarveWright sells them, but Sears (online) sell the ones from the invertor (RJR Studios) that are better for a better price. I have two 6" doubles at 180 and 220 grits. I also use an old Dremel with mini mops (Sears online again) and straight carbide rotary rasps designed to the Rotozip (Home Depot). If you can find one on EBay, get a "Contour Sander". Dremel quit making them just before the time CNC's firs got popular. I replaced mine there when it died, but there was a Sears version there also. RJR Studios also invented the Sand Flee - I have one of the originals.
