Clean Coaxial

Just build a cannon and want to show it off? Post it in here.

Well, lately everyone's been making "clean" guns; making the cannon, then leaving it unpainted, but using clear primer and cement. I decided to make my own.
It's just a basic coaxial, 1 1/4" and 1/2." The bushing in the front was cemented straight into the pipe.
We all know that diaphragms open extremely fast but have low flow, and piston open relatively slowly compared to diaphragms, but have high flow. This cannon has a piston with a diaphragm on the front, so it incorporates both the fast opening time of a diaphragm and the high flow of a piston. The diaphragm flexes back, allowing air to flow into the barrel, and then the piston is blown back, so air has tons of room to blast down the barrel.

If it's a 1" pipe chamber, then he could simply have cemented a 3/4" bushing inside it with little or no sanding.

Nice work noname!

The chamber is 1 1/4" Sch 40, the bushing is 1" x 1/2," and fits in perfectly with no sanding or modifiying (other than the "coaxial" part).
