1. An auxiliary support fixture for a steady rest having a plurality of movable fingers extending from one end thereof between opposing faceplates, operative to be moved by a pneumatically operated piston for engaging a workpiece to be machined by a tool, said fixture comprising:

  • a bracket mounted on one faceplate of the steady rest, said bracket including an arcuate slot therein which is concave with respect to the end of the steady rest;

    an elongated cylinder containing a pneumatically operated piston;

    an abutment member connected to one end of the piston, said abutment member including a stationary end face for engaging a workpiece;

    means for connecting said cylinder to the slot in the bracket whereby the angle of the longitudinal axis of the cylinder may be adjusted; and

    means for connecting said pistons of the steady rest and support fixture to a common fluid source so that said abutment member and steady rest fingers move in unison, with the abutment member being adapted to engage the workpiece diametrically opposite the machine tool to provide additional backup support for the workpiece during machining operations.
