The piston 50 is supported on the bed of a machine which has a rotary chuck 120 for the tool T. The bed has a fixed jaw 126 and a movable jaw 128 to grip the piston. The movable jaw is moved by a lever 156 connected to the jaw 128 via an overcentre linkage, Fig. 5 (not shown). The pistonrod 22 is supported on the end of an adjustable rod (196) under the machine bed.
