My First Pneumatic Cannon

Hey guys and gals! Here is my first attempt at a large(er) scale gun. It also happens to be my first pneumatic gun. Pretty simple cannon. It's all 1" sch40 with a 3/4" sch80 barrel and hopper. I modified a PVC Ball valve to twist 360 degrees and I plugged one end of the ball with epoxy so that 360 turn of the ball valve will allow one paintball to fall and then create a leak proof seal between the hopper and the barrel. I originally had a luckythirteen style hopper but added this ball valve design when I got sick of cleaning out my barrel from paintballs that collided and broke. Both the chamber and barrel are removable. That's why my chamber is currently not painted, it is just a backup barrel until I get my CO2 reg and tank from eBay. I bored out both Tee's that act as recoil support so that they are able to slide/spin while I turn my chamber to attach/detach it. This also will allow me to add a larger chamber if I ever wanted to do so. Hope you guys enjoy the pics and hopefully I will have a video up soon of me firing this little guy... it's loads of fun to shoot!

NICE!!!
Nice clean construction. Also nice paint job.

Rambo is right, thats quite alot of dead space. Does the PB fall out? He proably has some type of stopper and/ or doesnt aim at lower targets.

Dead space isn't much of an issue because I wasn't trying to make a really powerful cannon and not only that but it is a lot more powerful than it looks. I shot a paintball 3 city blocks at ~120psi. No, the paintballs don't fall out because I added some epoxy to make a paintball fit really nice and flush but not too much to cause them to break on the inner barrel.
