The periphery of the rotary drum has a set of elongate receiving channels formed thereon in which the spines of the brushes are slidingly retained. Similarly, the sanding units have elongate holders that are retained within respective retaining grooves formed around the periphery of the retaining sleeve. Each of the sanding units has a pair of sandpaper sheets attached thereto with an external portion of the sheets passing through a corresponding pair of adjacent slots formed around the periphery of the drum. The slots are interposed between the receiving channels thereon so that an external portion of each sheet of sandpaper within the drum is disposed between a pair of adjacent brushes. The retaining sleeve is fixed in position within the drum by the top and bottom covers which releasably secure the assembly together. The top and bottom covers are also provided with central holes for the passing therethrough of a spindle.
