Abstract: A method for adjusting the separation between a pair of roller assemblies. A frame is provided. One roller assembly is rotatably supported by a first pair of supports fixed with respect to the frame. On the other hand, another roller assembly is rotatably supported by a second pair of supports that are movable with respect to the frame. A pair of shims is provided. One shim is positioned between a first one of the second pair of supports and a first member that is fixed with respect to the frame. The other shim is positioned between a second one of the second pair of supports and a second member that is fixed with respect to the frame.

Abstract: A machine for continuously advancing sandpaper on a palm sander has a rear clamp bracket for holding a roll of sandpaper substantially longer than the sanding surface of the palm sander and stabilizing one end of a section of the sandpaper and a front clamp bracket for securing the opposite end of a section of the sandpaper. The machine also has a means for attaching the front and rear clamp brackets to an existing palm sander. The front clamp bracket also comprises a cut-off bracket to separate used sandpaper.
