Giant Piston

Hi all,

So our plan for the robot this season was to use a huge pneumatic piston to launch the ball (~20in stroke, 2in diameter). We've got our system pressurized up to the max 60 psi, but we're just not getting enough force to push the piston hard - right now it kind of just lazily slides out. We've considered that it could be an airflow problem as all of the storage tanks are connected linearly - we're hoping reducing the amount of tubing, adding more storage tanks (we currently have four), and reconfiguring the setup so that all tanks could "contribute" at once will help the problem, but we haven't tested it yet.

Does anyone have any experience firing pneumatics this large? If so, how can we get more force our of the piston? Would the above mentioned ideas work? Is there anything else we can do to make the piston hit harder?

Thanks in advance
