ABSTRACT:
Drum support apparatus including outboard and inboard hubs having outer surfaces adapted for interface fitting with the inside surface of a drum. The hubs while being supported on a shaft that is cantilevered from a frame have recessed areas on central portions thereof to cooperate with locking tabs located on a tubular member loosely fitted on the shaft whereby rotation of the hubs by approximately 20.degree. creates a semi-rigid assembly that is rigidly secured to the shaft by the tightening of a single nut at the center of the drum. An assembly of this type creates an equal distribution of force on the hubs, thus diminishing circular run-out of the drum.
