A modular workpiece holding apparatus comprising a first portion including a first base and a first jaw member supported by the first base and, additionally, a second portion including a second base positionable relative to the first base at a selected distance relative to the first base, wherein the selected distance is selected by the operator of the modular apparatus. The modular apparatus can further include a movable second jaw member and a drive member extending between the first base and the second base, wherein the second jaw member comprises a connector movable between an engaged position in which the second jaw member is operably engaged with the drive member and a disengaged position in which the second jaw member is operably disengaged from the drive member. The drive member extends between the first and second portions when the portions are positioned on a foundation plate at the selected distance.
