Step 2: dealing with the valve.
so alot of problems with phneumatic valves is that they are soo slow! even those fancy valves that people make from sprinkler valves, also not to mention that the volume of that which air can travel through those valves is relitivly low compared to the system that i engineered, also sometimes the position of the valve makes it ackward to operate the cannon, so i have came up with the end-all be-all solution to this problem! the system i engineered can do the following: close the valve automatically, the firing trigger can be placed anywhere and is easy to use , the speed and duration of the valve being opened can be adjusted in the field without tools , can be easily modified to fire remotely either via a small solonoid valve or by two long air compressor hoses, and most importantly IT WORKS EVERY TIME! ive yet to have had a single failure in the system since it was constructed
but the concept is that you use a phnuematic cylinder to pull a chain that goes around a sprocket bolted to the valve to rapidly open the valve.
