Abstract
An assembly of buff or brush wheels with or without spacers is stacked, compressed, and held together as an integrated unit to form an assembly of such wheels having a specified face width which then may be mounted as a unit on a machine arbor or drive shaft. The assembly is held together in such a manner that the ganged stack is yieldable and may be further compressed when assembled on the machine arbor. The assembly may also be slightly expanded to obtain a better fit on the machine. The wheel assembly in one form is held at the desired face width by adjustable ties extending through paired holes in core plates in the wheels. In another embodiment carriage bolts extending through the core plates form adjustable screw clamps.
