I also got the 3 inch polishing wheel for my Black and Decker power drill, but it was right and inflexible and couldn't get into the nooks and crannies and cracks and crevices and contours of the machine..... you do need electric power though, it's impossible to do as good a job hand polishing as you can with electric help. What I would recommend is that if you don't have room for a bench grinder, to get a multi-speed Dremel instead. You have to be careful with them because you can easily gouge the metal and put permanent deep scratchings in it if you hit the machine with any part of the Dremel besides the tip, but they are great for getting tight areas and really putting mirror shine on even the most tarnished of finishes. It does make a mess though, Nathaniel is right! Your hands and floor and clothes will just be BLACK when you are done! Good Luck!
