Abstract
A turntable for selectively accommodating different types of workpieces in which the system is designed for combining two turntables into one for handling two different workpieces which are rotated by two different motors. Preferably, one of the motors is connected to one of the tables for rotating the table continuously at a slow speed for treating large parts. The turntable is adapted to be selectively arranged for a second motor to drive a second table at incremental positions so as to index smaller parts for treatment. One drive shaft of the two motors is located within the other drive shaft which is hollow.
