Also if you do intend to shoot paintballs, A paintball tank would be much more practical. Especially given the low volume of air you'll be using in the gun. Even using the small 12g cartriges you'd get a few shots with each before running out of air.

I'm not a physics major or anything, but I would imagine with such a small chamber, barrel size couldn't be too large; thus limiting your types of ammunition.

I've got an idea and I'll start work on it asap. Just need to build a small launcher first.

I've been toying with the idea for a few days now. I've been trying to figure out how to make a single barrel net gun, like the one seen on Rob and Big. The problem is how to make the net spread out once fired. I currently don't have a gun at my apt, so I can't test anything. If someone could get so...

Thanks for the input. I was just looking to build a clean looking pneumatic. Performance isn't really a high priority atm. Just a simple/clean piston. 6790T42 is the MC master part number for the push button valve, but it looks nothing like the push button modded sprinkler valve joel has on one of h...

So I've been browsing the forums looking at all the piston guns and I'm noticing bulky ball valves or sprinkler valves as piston acuators. I don't have any experience with push button valves, but I was curious if ,on a small 2" Tee, you could use a push button valve to acuate the piston.

Anyway, The net guns i've seen fire a ,what looks to be, a lightweight net from a single barrel. The barrel is shaped like a cone. Any ideas of how the net spreads would be great.

??? Yeah its a better idea not to bring on to school

I mean at college

Ok, so I've been thinking of how this would work with a single barrel gun. I came up with one idea that ,with some tweaking, could work. You take a tennis ball and cut a small, 1"? , Hole on one side. From that hole cut the ball into 4 slices so the hole is the center. You will obviously need a slee...
