ABSTRACT:
A removable belt-backing mechanism (50) is provided for a hand-held endless loop belt sander (2). The belt-backing mechanism (50) includes an attachment bracket (52), which slidably cooperates with a pair of slots (66, 68) to provide a removable connection to the sander. A plate (70) is movably connected to the attachment bracket (52) by a set of pins (72, 74, 76, 78), and is biased toward the inside surface of the sanding belt (26) by a set of springs (96, 98) to provide a flat sanding area for sanding planar surfaces.
