My sister saw the myth busters episode where they used a cannon to shoot four tennis balls with a net( to catch (pidgons)(sp?). So now she wants me to make one for her she'll pay for it so it'll give me some fun.
heres some designs i made on ms paint.
I know they wont go to far with 4 barrels but im hopeing for atleast 100 feet.
i don't want to make a piston so im either going to use 2 1 inch modded sprinklers or a 2 inch toro.
A little picture
the blue circle inside the red circles is the chamber for the second gun.

What? Does that diagram make any sense at all or is it just me? Do the valve(s) trigger all the barrels at once? Is it an o/u setup or does the drawing distort it?

That makes a bit more sense now, so whats the point of having four barrels?

make sure that the barrels are pointing out a bit or else the net will not expand, what a nice brother you are
have fun making that thing, and make sure you post it when it is completed

what kind of connection will you have for the 4 barrel to get equal flow, this reminds me of an American civil war experimental canon with 2 barrels that had a chain between the 2 cannon balls, it was build to horizontally mow the marching enemy, there was a lot of problems with it, mainly it was the timing of the canon balls, this caused erratic flight and the chain to rip and the balls flying in random directions, I believe a few people we killed from test including a lot of grass, and a cow
you could learn a lesson or 2 from that story to help you on your cannon

well to get a equalish flow to all four barrels i will have a tee with a tee in both sides then 90s on all of the tees opening leading to the barrel.
this cannon isn't meant for really doing damage just for fun.
