ABSTRACT:
A pad sander paper punch assembly includes a base member having three upstanding walls for locating thereon a standard size sheet of sandpaper. A plate member is then placed over the sheet of sandpaper, the plate member having locating tabs which cooperate with the upstanding walls on the base member. The plate member and the base member are both perforated in locations corresponding to suction holes on the platen of the pad sander and a punch is then utilized to pass through the plate and base member perforations to appropriately perforate the sandpaper sandwiched therebetween. The base member is further formed with recessed walls so that the sandpaper may be creased at its ends to go over the sander platen with the perforations therein properly aligned with the suction holes in the sander platen.
