Made this little one a while ago,not to fancy and works just about as good as it looks,in other words hopeless.Tried to make it look good with some moulded PVC pipe.

25mm chamber.
15mm barrel.
Tee Piston.
120spi.

It worked well for a while but had alot of piston problems,kept leaking and breaking but when it was working well it was a good bit of fun.Used shotgun pellets with 2 felt wadding pieces and surpirzingly good long range shooting the pellets wouldn't spread to much and had enough energy at about 10 meters to still penetrate thorugh tree bark.But it's still a piece of sh!t.

Piston housing and things.Look at the moulded PVC, still doesn't make the gun any better though.

I did have a 1/4 ball valve on it for a while it worked wonders,but made it a bit weird to shoot could get the whole aim fire thing happening.

I'll see if I can find some things I shot as this cannon isn't used anymore got turned into parts....Because it sucked...

Looks is all it has going for it :wink: .

Looks ike one of thos things that you spend math class drawing up on your graph paper, then build it in a day and forget to put the piston on, rip it apart and fix it, then try to shoot it but have everything blow apart, then realize you spent more time moulding that one sexy-looking pipe with curves than you did on the actual cannon.

I like it...
