First Pneumatic Cannon.

[Ninty2lxcoupe]

Ok so here is pic's of my first cannon ever. lol.. I don't have any damage pictures because the only thing i have right now to shoot out of it is spuds.. and sadly.. they don't do much. lol.. Tell me what you guys think.

Chamber is 2"
Barrel is 1.5"
Modded 1" Sprinkler Valve.

It's really nice.

The only thing I don't like is the gauge and schrader fill valve going through only one layer of pipe. That is not really a good idea since the hole weakens the pipe around it. Going through pipe and coupler would have been much safer.

I assume it is shoulder or hip fired. You would get a bit more performance by taking out the air hose to the valve and just attaching the blowgun directly to the valve. Of course that means finding an 1/8" fitting to use with the rainbird valve, but it is worth it especially if you read on...

It looks like you threaded the barrel onto the valve, now you can make that tennis ball or golf ball barrel and start using some reusable and uniform ammo. Use GGDT (wiki) to get the optimum sizes based on your chamber.

Nice paint job too.

You could actually make spuds do alot. http://www.spudfiles.com/forums/my-pota ... 10745.html
if you look at this post this guy has alot of videos on combustion spudguns. He made a potatoe go through a wall. Yea so potatoes can be powerful. Your valve might not be able to do it but if you get at the right psi you could probably do it. If you had more air flow in your valve then you could probably do it. This is the only bad part about pneumatic sprinkler valves, they dont have to much air flow. If you further modify your valve then you can get the same flow as a 1/4 ball valve according to a how to post that shows you how to further modify a sprinkler valve. Great cannon though nice paint.
