[Mr. 1033]

My team is in the process of rapid prototyping a launcher using 2-4 cylinders with 1.5in bore and a 10in stroke to launch the ball.

We have done our hw on here and youtube to see that the concept should work.

We are having a rough time getting the "burst" needed to propel the ball.

Any tips out the as far as how to legally set a system up?
