Abstract
A turbine-driven sander includes a nozzle, turbine chamber, and a valve chamber. A flap valve mounted in the valve chamber opens the turbine chamber to a source of vacuum, thereby driving a turbine rotatably mounted in the turbine chamber. This rotation in turn vibrates a platen through a direct-drive system. The platen is supported upon one of the housing members by a pair of platen support members, each member being temporarily connected to a metal plate to form a subassembly. Each platen support member is a molded plastic unit having a cross-member, a pair of snaps for engaging the metal plate, and a pair of flexible posts extending from each end of the cross-member. The support member is attached to a mating recess in the lower surface of a housing member. The flexible posts are attached to a platen.
