:?: Hi I'm kinda like a newbie so I was wondering if any one could help me with designs for making a pneumatic cannon. If anyone feels like helping then it would be greatly appreciated. Thanks. :D

start by telling us the general shape you want it to be, then size, then tell us what valves you want..

so we know what to tell you

i sudjest you use a selenoid valve because it is cheaper and easier to use than a ball valve plus it shoots farther. it looks hard to install but its actually really easy
