Comments: This is a really fun gun to play around with. I call it my “party shotgun.” I like making a slit in tennis balls and filling them up with caulking, let it dry for a few days at the slit, and then launch it- makes a nasty mess when it hits a wall or something. It’s just a basic design- my first pneumatic cannon. Very sturdy construction, no loose or wiggling pieces.

Nice cannon! Despite my barrels for aerodynamically better ammunition, I still love to shoot tennis balls!

What kind of distance do you get with water-filled tennis balls? Have you tried water-filled yet, (they go farther)?

Just a little suggestion for next time. Whenever you have a large-diameter barrel, try making a piston valve! They're cheaper and work a helluva lot better for larger diameter barrels. Remember, for a 1" modded sprinkler valve, the flow is equivalent to that of about a 9/16" hole. For a piston valve, you can practically make one with flow equivalent to a 3" hole.

But nice cannon anyway! You still wouldn't want to be caught on the receiving end of one of that cannon's serve!

iv always thorght having a small pipe from chamber to a bigger barel would severly restrict the air flow and reduce peformance

anyway a very clean and kool cannon

Lovely! I like it, I just do. It reminds me of somthing...

Mark, i haven't tried water filled tennis balls yet but how do i do that? cut it and then fill with water and glue the opening shut? Sounds fun though. I love shooting balls filled with caulking, they're soo messy. Ya if i upgrade this cannon someday then a piston valve would be my next thing to do, this is my first pneumatic bye the way. Would a piston valve dramatically increase my gun's power? And Experament, The chamber is 3" and the barrel is 2.5" diameter, so i am going from a larger chamber to a smaller barrel. If you read up above at the specifications, my chamber to barrel ratio is 1.07:1. I know, i know, it used to be 1.5:1 but it just took too long to pump up the chamber to 100 p.s.i. when i was out just with a bike pump. I guess if i made a piston valve for this gun i might as well just get an onboard CO2 injection system too for convenience. I have a couple paintball tanks i could put to good use. Any other suggestions? I need feedback cuz i'm new at the pneumatic stuff. thanks.

nice job overall. i really like how you built the blowgun right into a handle on the valve. im tempted to try that on my own cannon. you did a very clean job, keep up the good work mate!

Bloody hell man! It looks very pro and clean, love the handle too...gonna try that with my sniper.

can u e mail me a diagram tyler2@cablespeed.com

this is the cooles conceps i ever seen nice job

ouch!! must be painfull Awesom design though..

to fill a tennis ball with water just go to a pet shop and get a syringe. Stick the needle in the tennis ball and just keep refilling it.

Sweet! That's awsome, I wonder what kinda Damage you can do with that?

This is an old thread, try not to post in threads more than a couple of weeks old unless you have something really important to add. There are a bunch of people on here that get pissy about that.

where can you get 2.5"pvc other than the internet?

It is fairly rare, ive never been able to find any. The internet isnt a bad place to get t though if you buy other exotic plumming parts. even if you did find some at a harware store, fittings for it would be nearly impossible to find.
