Oh my gawd what have I done...

[magnj]

wow, I have another summer project to add to the list. Last year we made one with fire and PVC but this seems so much more fun.

I couldn't help but laugh out loud when I read that first post.

[WickeDKlowN]

Damn... I remember this thread from back in the day.

Now I have 3 summer projects: Harpoon Gun, Trebuchet/Catipult and a Pneumatic 'Tater gun

[LittlePaintballBoy]

try putting like 300 paintballs in it and shooting. take a picture of that!

Valve

That's a great project!

I have a friend who did something similar to shoot 30 paintball at once. Works great too.

What I would recommend to simplify your design (and make it a bit smaller): instead of using a manual valve with a spring, use a sprinkler electric valve. Only requires 9V to open and is sold for about $25 (CAN). Those should be easy to find in big renovation center.

Note: these electric units only works with 120psi or less...

Have fun!

my older brother had a friend who uses propane to propel his potatoes...or so he says

This thread must be before my time here how much would i have to change from your plans, if... for some reason i was putting 1200 psi into it?

Everything. Don't use 1200 PSI.

The valve leaks at 600 PSI, you could have catestrophic failure at 1200. (In other words, something could explode and take your face with it.)

The pipe isn't even rated for pressure. It SHOULD hold but you'd have to be both crazy and stupid to use 1200 PSI. Paintball players lose respect for the power behind compressed air, and that can be a fatal mistake.

[Spleen]

yea, i was just thinking about that today at work.. my idea now is to use a preset pmi tank, reg it down to around 300 psi.

[Thordic]

This design is actually pretty ineffecient and underpowered at its current pressure. The design is far from perfect.

Youd do much better designing a system that ran at about 120 PSI, with a much larger dump chamber, and some sort of large-opening solenoid to fire instead of the crappy ball valve.

I'm pretty sure you'd get better results out of that sort of setup than this design. And it would be lighter, due to the fact you could build it entirely from PVC.
