This is my first pneumatic that actually works. I got a bit crazy with the primer, and it dripped all over the place. Its chamber is 1 1/2in by 7in and the barrel is 3/4 by 30in. The ball valve is 3/4 inch and is solvent welded onto the cannon.

Very Cool gun(simple and basic). Like the bullets to. The gun would be cooler if you used a sprikler vavle. Walrus i looks like it went through the box on the picture.

This is a vid of the gun in action.
http://www.spudfiles.com/forums/album_s ... ?pic_id=71

I can't use sprinkler valve because they are not available in my area. The bullets are wooden dowels with nuts (hehe) on the ends to give them wieght.

The tire valves do go in a 3/4 in hole, but I *cough*made them fit*cough* in a 1/2 in hole. I don't see any safety issues with them.

The bullets did not tear a clean hole, instead they left a flap where they went through.

Thanks for all the compliments.

100 psi. My compresser, to be blunt, sucks. The song in the vid is Sonne by Rammstein.
The reason it only goes up to max psi is that there is a leak in the air chuck, so whenever I fill it, more air escapes than goes in, and it equalizes very quickly.

what is the air chuck? is it the car valve for pressurising? if so, couldn't you simply silicone seal it?

On your air compress you can lossen or tighten the screw in the pressure regulator and you should be able to get more pressure out of it that way. Thats if you have one (pressure regulator) on yours, it will be a bolt with a spring over the threads and you will losen or tighten that bolt. You should also try to fix the leak (if you can).

Jylz, the air chuck is the tool you put on the tire valve to fill it. I'm gonna get a new airchuck in a few days, I'm getting a paycheck in two days, so I'll get it then,

About 150, because the leak in the chuck allows air to escape out of the schrader to, so that blows, and my compressor sucks too. I got to get a new one.
