ABSTRACT:
A vise has a fixed jaw mounted stationarily relative to a vise body. A movable jaw is supported on side rails that have upper way surfaces. A jaw nut that exerts a downward force on the movable jaw operated to move the movable jaw along the way surfaces. Resilient member is provided between the under side of the movable jaw and at least one of the way surfaces to space the movable jaw slightly from the way surfaces until the movable jaw engages a workpiece, at which time the resilient material compresses and provides a positive hold down force on the workpiece.
