Okay would something like the rough drawing below work? A ram is pulled back by a pneumatic piston, the surgical tubing wants to pull the ram back. To fire it the pressure in the pneumatic piston would be released allowing the surgical tubing to pull the ram out and hit the ball. The only thing I am really kind of worried about is the sergical tubing will loose a lot of force trying to pull the piston out even though there is no pressure. Thoughts? Ideas?https://docs.google.com/file/d/0B7jE...p=docslist_api
