ABSTRACT:
An assembly for converting a conventional drill press into an oscillating spindle sander is disclosed. The oscillating spindle sander assembly is comprised of an auxiliary motor which is adapted to be mounted on a drill press. An eccentric drive is attached to the rotating shaft of the auxiliary motor and is used to drive a push rod in a lateral reciprocating motion. The opposite end of the push rod is attached to one of the spindle spokes of the drill press, and causes it to move in a radially reciprocating motion which induces the drill press spindle, drill chuck and a sanding tool mounted therein, to move up and down in an oscillating motion. The oscillating spindle sander assembly of the invention can be easily disabled and the converted drill press returned to normal operation by removing the push rod from the spindle spoke of the drill press.
