Oscillating drum sander

An oscillating drum sander comprising:

• a main frame defining a longitudinal axis along which a workpiece is adapted to move;
• an oscillating sanding drum assembly mounted to the main frame and caused to both rotate and axially oscillate relative to an axis transverse to the longitudinal axis of the main frame so as to sand a workpiece when positioned in contact with the oscillating sanding drum assembly,
• further comprising a drive motor mounted to the main frame, the oscillating sanding drum assembly being positioned in mechanical communication with the motor,
• wherein the oscillating sanding drum assembly comprises an axle supported by said frame and defining said transverse axis;
• and an abrasive cylinder mounted about said axle, the abrasive cylinder being positioned in mechanical communication with said motor,
• wherein the oscillating sanding drum assembly further comprises transverse rotational bearing means for supporting the axle relative to the main frame so as to permit both rotation of said axle and axial movement thereof relative to the main frame, and
• wherein the transverse rotational bearing means comprises a pair of spaced pillow block bearings, respectively, each engaged to an individual opposed end of said axle, said pillow block bearings each being supported for movement in the direction of said transverse axis relative to a portion of the main frame.
