3 inch Penumatic Cannon

[elitesniper]

Well im not sure i can call this little thing a cannon but what the heck. This is my smallest pneumatic its only about 3 inches long , its a coax it has a 6mm barrel for bbs the chamber is 3/4 sch80 , it is filled with a sharader valve and exhausted with the sharader valve , its runs at about 100-170 psi. oh and the sealing face is mousepad everythings held in with epoxy ,hope you guys like

Wow that thing is tiny! I bet it's fun though, and what kind of performance do you get with this "cannon"?

[elitesniper]

about the performance of an airsoft springer haha but a tiny tiny tiny tiny bit better

Wow I was expecting some cannon with a 3" barrel.
Nice performance, reminds me of my failed attempt at a mini coaxial.

Heres mine, except it didn't work.
It was designed to shoot the ball points out of a pen.

WOW thats reeaaly small lol to bad it didnt work though

[c19o]

Well it kinda worked, the piston sealed but the pressure pushed the barrel out. Piston was an eraser with 1 layer of duct tape.
Tomorrow if I get bored I'll finish my other cannon, its a .177 cal barrel sealing piston gun in a tee.

BTW, how well does that epoxy bond PVC to PVC? Without sanding or roughening up the surface

[elitesniper]

you didnt epoxy your barrel? o yeah i forgot to put its service able!

[c19o]

No, I used clear silicon gasket maker. Bad, bad decision I made...

Not my 4" piston, it ripped out the washer that was epoxied in.
