Heres something simple I through together tonight. Its just a simple ball valve dart gun. 1" piping for the chamber, and a dart gun barrel. Its extremely powerful. It can shoot those metal needle darts through 1x4's. Maybe in the future I'll put a sprinkler valve on it with a electric trigger.

That is a cool cannon. If you do put a sprinkler valve, use a blow gun, it will open much faster. What is the hose and hose clamps for? Is that how you attached the barrel?

Spiffy idea to support the barrel.

Nice gun. It looks like a fun plinker to have around for those times when you get bored.

I see you are considering a sprinkler valve... this would be a very good idea. I used to despise 1" sprinkler valves, believing that no possible power could be attained from a valve with such low flow. However, after observing more and more sprinkler valve cannons, I have come to the conclusion that a sprinkler valve is possibly ideal for cannons with barrel diameters .5 and under. However, a 3/4" QEV still is much better than sprinkler valves...

Dude, if you got a sprinkler valve, then that would be wicked!
