Abstract
A steady rest follower for a workpiece comprising a frame supporting a slide which is movable in directions toward and away from the workpiece. A pair of vertically spaced support wheels are mounted on the slide for engagement with the workpiece. A pair of springs yieldably urge the slide rearwardly away from the workpiece and into engagement with the peripheral surface of an eccentrically configured roller member that is mounted on the frame. During the machining of the workpiece, the eccentric roller member is rotated to move the slide against the pressure of the springs toward the workpiece so that the support roller members are maintained in continuous engagement with the workpiece as the size of the workpiece is reduced.
