ABSTRACT:
A steady rest is disclosed for alternatively supporting the interanl and external surfaces of a tubular workpiece during a machining operation. Each outer end of a plurality of movable fingers includes first and second workpiece contact devices such as rollers. The second contact device is offset from the longitudinal axis of the finger so that it may engage the inner periphery of the workpiece. The opposite inner ends of the outer fingers ride in slots having opposing arcuate cam surfaces. One cam surface provides backup support for its finger when externally contacting the workpiece while the other cam surface insures stability when its finger is contacting the inner periphery of the workpiece.
