Another Craigslist find. Yesterday I bought a sanding belt and sanding discs to get this new find ready for use. The sanding disc plate was loose, so I took it apart. It turns out that the drive pulley is badly worn! It's made of some type of plastic and after checking on Sears Direct this part is no longer available!! Any ideas on where to get some sort of replacement? Or do I try to make one out of wood???
