Abstract: An auxiliary support device for a workpiece is connected to a bracket mounted on a side face plate of a steady rest. The support device includes a member extending from the end of the steady rest for abutting the workpiece diametrically opposite the machine tool to provide additional backup forces during machining operations. Preferably, provision is made for adjusting the angle of the support device relative to the workpiece and for moving the abutment member in unison with the fingers of the steady rest.

Abstract: The checking fixture includes a pair of opposed gaging fingers drivingly interengaged so as to be moved together to engage a workpiece, with a simplified arrangement for manipulating the position of both the gaging fingers with a single control knob, insuring a uniformly applied gaging pressure for urging the gaging fingers into contact with the workpiece while compensating for eccentric location of the workpiece in the gage. Rotation of a control knob assembly in one direction causes opening of the upper and lower gaging fingers, the assembly allowing a "stay-open" positioning of the gaging fingers in any adjusted open position.
