ABSTRACT:
A small size vice constructed to hold small parts while being work processed on up to three sides with one clamping of the part being work processed. The small vice uses a rigid frame design applicable for being clamped in a larger bench vice, bench mount bracket or machine table clamp having rigidity not found in small vices. The small size vice has narrow jaws and very long movable jaw travel for it's jaw width and with the jaw travel perpendicular to the clamping surfaces of the jaws. The small size vice also has an underside rigid web reinforcing substantially the length of the vice to prevent the vice from bowing from vice jaw clamping force and to provide a web for being clamped in a larger bench vice (or other clamping device) with the smaller size holding small parts being worked on over to one side of the bench vice. The two sided shoulder at the top of the underside rigid web prevents vice slip down when the small vice is clamped in the jaws of a larger vice.
