ABSTRACT:
A vise having two spaced-apart end plates and a plurality of tie rods extending therebetween for accurately and firmly retaining the plates in a fixed spaced-apart positioning. Two workpiece clamping jaws are supported relative to the plates, and a force applicator is connected to one of the jaws and is within the confines of the connectors or tie rods between the plates for applying the clamping force within the boundaries of the tie rods for absolute accuracy and strength. The vise can be clamped to a worktable in one of two positions for positioning the workpiece either vertically or horizontally. A split retainer ring is utilized for the accurate assembly of the tie rods and the plates.
