I was contemplating about making a coaxial type air cannon design but I had a thought about the pressure rating. We know that certain pipes has been factory tested to withstand a certain amount of pressure inside of it. But what if that pressure is being applied outside of it? That's basically what'...

I have done test with sprinkler valves, duel sprinkler vales, triple sprinkler vales, piston vales, and ball valves. I have surprisingly found that a basic ball valve performs the same if not better than the triple sprinkler valve system. I built a 2'' piston valve but never really recorded anything...

Hello people. I would like to share a project I've been working on for awhile. Its going to be an air cannon designed as an artillery gun for paintball games. Below are some 3D images I've done of the final vision (I do 3d modeling). Its going to shoot groups of water balloons at the opposing team. ...

Neat! We need a few more details on how it works, it looks like there's 3 sprinkler valves and the chamber can't be the whole length of that bottom pipe (or could it?). Only suggestion I have is to pneumatically pilot the three valves instead of electronically. You can hear the diaphragm "honking" ...

Here's some pictures of the 2nd prototype. Its a 1 1/4 inch barrel that allows a 2ft shell to be loaded. I built two different breach loading mechanisms I thought could work. The first is a screw in breach that has the air enter from the bottom. The 2nd is a cam lock where the air enters directly fr...

I'm continuing to flesh out all the details. Double checking all the proportions to make sure its turnout out the way I want it to look and feel. I started thinking about the possibility of towing this like a trailer. I made some provisions for a leaf spring and a tire fender. There's alot of other ...

I made a video demonstrating the concept for it.


I decided to forego the legal trailer idea. There's too much involved, its also more expensive. I still plan on towing it off road though.

I got to physical work again on the prototype gun. I'm starting with the gun and building down from there. I built the platform the gun will sit on and hooked up the recoil system. The gun sits on a small platform that is connected to the base using drawer sliders. You can also see the breach loadin...
