Never really named any of my cannons these commercial like brand names everyone uses, so I thought I'd give it a try.

Main reason behind this build was hours upon hours of studying for the DAT exam and when it was all over I felt very much like building another cannon, plus my current paintball cannon is kind of weak having only a sprinkler valve and lots of dead space, so it gave me a good excuse to build another one.

This is a 1.5" barrel sealing tee with a 1" o-ringed piston and for actuation I can use either my ball valve or my modified blowgun that I bored out for max flow. I used some plumbers putty at the beginning of the barrel so the paintballs wouldn't fall into the piston area, to reduce blow-back and to maximize barrel length. At 60psi compared to my sprinkler valved cannon at 110psi this is much more powerful. The paintball hit the target so hard the paint literally vaporized and there was only remnants of the shell on the plywood. I would like to invest in a chronograph to give some depth to these claims, however I could instantly tell the difference in power. This thing is a beast for a 1.5" tee valve.

For those interested, it cost about $30 for everything you see in the pics (including the ball valve and blowgun) and around 1.5 hours of work on the gun and piston.

Also as you can see I am a huge fan of flush fittings and double walled guns which is why the entire chamber is couplings and not just sch40 pipe. Little more time and money, but I think it's worth it for the looks and the added safety. Any suggestions on a paint color? I was thinking like Krylon's green or yellow... I'm sick of painting my guns all black :)

Nice! What material did you make the piston out of?

Oh, and I second the motion for green!

Thanks guys.

Ya I think green sounds like a good choice.

1" sch40 fittings just so happen to fit beautifully in 1.5" sch40, to the point where an o-ring isn't even needed... but we all know that an o-ring will still improve performance a great deal. So I just took a 1" coupling and added an o-ring to that baby using my ultra secret no-lathe-o-ring-groove technique, bob's your uncle, and we have a piston =)

I think you should put on a glove and smash paintballs all over it. It'd be better if you had different colored paintballs.

Really clean cannon. 30 bucks for more power? Sounds like a deal to me!

Very nice cannon you have here. Double walled chambers do look really good, but I personally am too lazy to build one :p

Thanks for the comments everyone :) I really like your idea spuzi14 and I just might do that... I guess I'd have to clear coat over afterwards or it would just rub off. I think getting another gun and shooting this one and clear coating would look so cool... like it was actually used in a war/battle or something. But ya, that's $30CND and considering at Home Depot a 1" sprinkler is $20 alone... I'd say that's a hell of a deal.

Thanks Rmich, ya I agree it's a pita to do it, but tis sweet lookin' and I'm OCD about that kind of thing :)

It's been a while since I saw something from you. Very nice comeback.

I really appreciate its cleanliness and the presentation of it. Keeping dirt off the work is half the battle and it seems you won.

One minor suggestion: Try turning the blowgun around so the button it on the other side. This will be more "trigger-like" and seems like it would be more ergonomic.

Nice work, though I would have gone for a longer barrel and larger chamber in there interest of more power.

How about a nice <a href="http://www.e22.com/peacecrane/temp_jpg.htm">camouflage pattern</a>? I'd love to see a cannon done in sky or urban camo some day.
