There isn’t a design. I am looking to make a dozen or so simple (maybe co-axial), safe and cheap PaintBall Bazooka's (about 12-20). and 2-4 mortars.

I run paintball events over the summer and the mortar's and Bazooka would add a fun dimension to the game.

I was looking for feedback on a basic 3" Chambered 1 1/2" Barreled co-axial and if anyone had any suggestions.


Thanks.

the valve works like a blowgun but blowguns work better. I'd never trust myself to machine such a high pressure system, I'd go with a regulated paint ball gun, and an under barrel coaxle grenade launcher actuated by a sleeve valve: compact and fast

but really if a high pressure ball valve is so easy why not use 2 of them for the gun. much easier and safer

I want to make my own valve, it will be much faster than a ball valve, firing and filling. The pressure isn't that high, can easily be contained.

What is a sleeve valve? Sound ovious but want to be sure.
