my 2nd cannon

this is my first rifle. the chamber is 22" long made of 1.5" pvc(38 cub. in.) the barrel is .5 in and is 4' long (9 cub. in.) The ratio is a little high at like 4:1 but it works out good. the valve is just a 1 in sprinkler valve.
the breech is from PVC ballistics with a slight change. The stock is blocked of with a piece of pvc. I am waiting on a scope but I can still fire it pretty accurately. My ammo of choice is a stick of fiber glass wrapped in duck tape to fit, it goes through a 1/4" plywood at 15 feet.
I'm also going to rifle the barrel but the last dowel I tried broke so I got to get a new one. I am going to paint it but I haven't got around to it yet.
Well thats it I just hope I posted right.

nice except why is the sprinkler valve on the bottom and does that stock do anything productive

The stock is there to hold the scope when I get it but that might be a while.
I just had the sprinkler on the bottom because it fit for the trigger

i second risto....OMG...use clear freaking primer or paint it with like 5 coats of primer to cover up that uglieness....ugh...i hate purple primer and you should buy clear it makes your gun so much cleaner and better looking....so anyway its clean overall exept for the primer...i like it...

I like the look of it(design not the stains) and the removable butt stock is freakin awesome. Nice huge cannon also you should of used a piston on the big cannon instead of those 2 sprinklers I think I see. Overall pretty good minus the stains. Looks like a nice plinker.

yeah I got to get better on the stains
I got some paint though so I should be able to start that pretty soon.
I think that for my next cannon I'm going to use a piston valve
That is a belt it was the best thing i could find to brace the whole thing

might want to extend the barrel on the 2 compression chamber cannon. look up c:b ratios (chamber:Barrel)

the barrel ratio for the big cannon is 2.5:1
Yeah I find the breech works really well
