An assembly comprising a plurality of pistons, each of the pistons comprising of a cylinder and a piston rod, a first collar for supporting the cylinders at a first end and a second collar for supporting the cylinders at a second end, for each of the cylinders, a first air inlet through the first collar into the first cylinder end and a second air inlet through the second collar into the second cylinder end, a plurality of valves, each of the valves connected to a source of compressed air, and a plurality of air hoses interconnecting each of the valves with one of the air inlets. Also, a method comprising the steps of providing a sensor for sensing when the piston is in a first position, placing the piston in the first position, calculating a first time interval between commanding the piston to move from the first position to a second position and when the piston is no longer in the first position, calculating a second time interval between commanding the piston to move from the second position to the first position and when the piston is in the first position. The reaction time interval comprises the first time interval and the travel time interval comprises the second time interval less the first time interval.
