Title: Direct drive system for a turbine sander

Abstract: A turbine-driven sander includes a direct drive system in which a one-piece thermoplastic shaft is rotatably journalled in a housing and mounts a two-piece turbine at one end and a counterweight and bushing at the other end. A machine screw is inserted through a longitudinal clearance bore in the shaft and clamps the turbine halves, shaft, counterweight and bushing together. The bushing is in turn pressed into a ball bearing, which is mounted in a platen. When the turbine rotates, the platen is oscillated, balanced by the counterweight.
