We are using three 1 1/2" x 8" stroke cylinders with the rod end vented to atmosphere, and one 3/4" bore x 10" stroke cylinder with the rod end connected to the retract port of a valve. We are using 4 SMC NVZ valves actuated simultaneously to fire it.
We also have two reservoirs at 120 PSI, and two at 60 PSI to feed the cylinders. We are kicking with the vacuum on, so the cylinders have to build up to full pressure before the ball breaks loose.
