ABSTRACT:
A clamp structure for holding a workpiece in a vertical position, and which is reconfigurable to enable manufacture of an opposite hand version of the workpiece, includes a plurality of pillars mounted on a fixed solid base and a clamp post on each of the pillars having a top end on which is mounted a clamp. An air cylinder has one end connected to the pillar and an opposite end connected to the clamp post. The air cylinder is connected to a source of air pressure for pressurizing the air cylinder to a pressure sufficient to substantially counterbalance the weight of the clamp post and clamp. A pair of holes in structure mounted on the pillar, and a pair of holes in structure mounted on the clamp post are alignable in pairs for two heights of the clamp for two different configurations of the workpiece, so the clamp structure can be used to clamp two different configurations of the workpiece.
