i did not make this cannon it was some other guy on this websight i just posted this pic so i could ask him specific quetions

that is the weirdest way to ask a question
I think the ball is a safety or for muzzel loading, open it, and there wont be air trapped behind the projectile, thus making loading the gun easier

i thing the black solenoid valve is different because it's cheaper, another big valve is not nessisary

just my opinion

Salad tosser got it right on (it's my cannon, lives under the deck at my house). The small vavle is because, well, it's small. I didnt need the flow of one of the bigger ones, so I wanted to make it more compact.

The ball valve it to make it posible to load this sucker. Ramming something home down a 8' barrel is hard enough without it wanting to pop out!

id like to see how this fires, do your valves actuate quickly?

that is the most complicated cannon i have seen so far
how long did it take you to build this..this thing
i have made a single solinoid gun and it took me 2 days to build (but i modded myn to be let off pneumatic)
yer so how fast does it shoot at
wat psi does it use
how far does it shoot

thats amazing all sprinkler valves organized for exelent flow and power
