>>HISTORY<<
February 2004: Purchased this polishing head in a Michigan used tool store.

September 2016:
Added steel spacers to move the buffing wheels toward the shaft ends.
Attached to a 1/3 hp Dunlap motor with a 3/8" V-belt and 2½" pulley.
Motor sits on a Craftsman floating (pivot) mount.
A block of wood props the motor base back edge, to keep excess belt tension off the polishing head Oilite bearings.
Bearing lubricant: SAE30 non-detergent oil.
Spiral sewn buffing wheels with Emery (left) and Tripoli (right) compounds.
The cut up ½ gallon milk cartons keep the compound splatter off the motor and surrounding area.
