Here is the idea as to what i want to make. A cannon with 2 chambers. Both 3.5 to 4' long with 2 modified valves. using a 1.5" to 2" barrel. How do i plug that information in. I have read the whole site and im still confused.

hmm i think you should try something a bit more basic for staters... don't go with a duel chamber cannon just yet, you will have problems unless you have made a pneumatic before. just use a 3/4"-1" ball valve with a single chamber about 3 to 4 feet long with a 1.5" Sch40 barrel. good luck.
