Tends batteries of automatic machines that tumble wads for shotgun shells to remove feathery edges, gauge thickness, and lubricate circumference with wax: Fills tumbling barrel with wads from overhead hopper and starts tumbler rotating.
Examines wads after estimated time to verify that edges are smooth. Starts machines that reject too thick or too thin wads and replaces filled barrels under accepted and rejected chutes. Dumps accepted wads into pneumatic conveyor that carries them to lubricator hopper. Turns steam valves to liquefy and regulate flow of wax over lubricating plate. Starts feeder plate to arrange wads flat-side-up and feed them between roller and lubricating plate that coats sides with wax. Weighs designated number of wads at prescribed intervals before and after lubricating to determine amount of wax applied. Clears jammed wads, using wire hook.
