Its always more fun to make it yourself i think. besides then i have to pay for co2 and a regulator... id rather just make it out of 5 dollars worth of parts and be able to use my compressor... or even scale this down and have it just attach to a smaller gun... maybe make a quick connect setup so i ...

portable multishot pistonvalved cannon

the whole goal is to achieve several shots with this puppy... Im thinkin the main chamber will have an airtight piston, sealed with an o ring most likely... this will have a very strong spring behind it so that when you pressurize it from in front of the piston the spring compresses... then as the c...

I kept thinking about how big the pilot was. That's really the shortest I could make it. I mean I guess I coulda just put an elbow on there and threaded the shrader through it but a tee seemed like the best idea. And thanks Im gonna try sanding it down when I get home from college. Hopefully that wo...

O really. This is from a year or two ago so I don't really remember. I usually check the parts to see the pressure rating that's usually put on there somewhere. I don't think I have gone above 50 psi good thing I guess. I'm gonna scrap it anyway for my piston gun soon.

Basic pneumatic gun

This is one of my first pneumatics. It uses a coaxial idea, meaning the barrel is in the compression chamber, but there is no piston, just one lame sprinkler valve. This is the only picture I have of this right now, I will take more when i go home for the weekend, but you cant see the whole thing. T...

A new typer of piston valve...

I'm trying to think of a way to create a piston valve that rotates. Basically instead of moving back and forth in a pipe it would rotate... and ideas how to do this?
