So your ready to play with the big boys? If so we offer you the SpudZooka 234. This canon has the capability of sending that spud hundreds of feet farther than the fueled style. If you want better control of that power, here it is. The power is easily controlled by simply regulating the air pressure. We offer you detailed step by step instructions for building your first pneumatic cannon.
This cannon uses a floating diaphragm as well as an industrial quick exhaust valve. This cannon has a 3" outer chamber with a 1-1/2" barrel which is 72" long.
How much power are we talking about? Well, at 50 feet you should easily be able to punch a hole through 1/2" plywood with a potato. I would highly recommend not placing the target in front of your shed. It will probably go through your target, and to your amazement, your shed. That'll get a good "Ah-shit" from you, and "wow that was cool" from your buddies.
