This is my first real attempt at a spud launcher. I have made several minis, some ( very dangerously ) out of non rated pipes and soda bottles, and one sad attempt at a PVC one, all combustion. This is my first real attempt at making one thats nice and safe, also my first pneumatic. It uses a 3/4" stainless steel ball valve, which I know most of you are going to look down on, but I have to say it opens very quickly ( thanks to alot of wd40 ), much much faster than the PVC ball valves. The barrel is 1/2" and the chamber is 1 1/4". The only thing I would change on it is the shrader valve and the poor placement of it. The pressure gauge and the T that it mounts off of as well as the support were added after I had 'finished' it, or else I would have placed the shrader valve on the metal fittings were the pressure gauge is. The shrader valve ( the only one that I could find ) is supposed to be used for car tires, it has a huge round rubber peice behind it and I know that there is no way in hell that it will be expelled from the pipe. I also belive it said it was rated to 160psi on the box. I may add a second brace soon because the barrel slopes downward about 1/4" from the valve. I don't care to much about the 'purple paint job', but I may paint it some day anyways.
For ammo, I bought 4, 4' long half inch dowl rods. I wrap the ends in duct tape just enough so that its a good fit ( for some reason they are not quite 1/2" ), and at 100psi they can do some real damage, and they are also reusable, I hate wasting potatos/frozen grapes. I may have some damage pictures tomorrow.

Thats a great first gun dude, Id stick with a ball valve, but some will tell you to use a sprinkler valve. Ball valves are fine and its he's first gun so why not leave it intact? LEAVE HIM ALONE!
Oh i am so sorry, me drunk or smthing. |

Dude... thats a POS 
....Pretty Owesome Shooter 
I dont hate ball valve cannons. Sprinkler valves screw up all the time, homemade piston valves can break, burst disks are annoying as hell.... but a ball valve cannon pretty much doesnt break (I have found that premade QEV's dont screw up either, but thats a different story)
Anyways, nice! |

Modifications to the valve or barrel are too dificult now that my brace is cemented to the barrel. I may extend my barrel with a coupler and length of pipe.
I have this idea of getting a 3 inch pipe, capping it off on both ends, and connecting it to my chamber with another ball valve, so I can just fill it up to ~100psi and get quite a few shots out of it without having to go back and fill up every time. Bad idea or good idea? |

That's not what my nick means btw.
Cool gun. Simple and easy. Your next gun should how ever at least need a sprinkler valve, or bether (and more fun to make I think) a piston valve. |

| I was considering a QEV. Although I do enjoy manually creating and modifying things, I find premade things tend to malfunction less and last longer. I don't have that much room to shoot stuff. I live in a golf course area which gives me space to shoot stuff far but it is suburban and I try to keep it quite and accurate as possible. |
