If you are talking about your ballvalve gun, don't even think about it.
If you have another idea, that WILL outdo me, I'd love to see.

Maybe I can finally copy you hahaha

I know..double post, but i have some news...
I have extended the secondary chamber and can get off quite a few powerful shots now.
I have started work on modifying a ballvalve into a breach loader wich accapts only one marble at a time from a magazine.

I had already changed the barrel into a 20mm outside diameter aluminium one, to shoot normal sized marbles.
It is beginning to look more like a hunting rifle now.

Still to be done:
Complete the mag
Add return spring for the exhaust valve
PAINT!!
Maybe add laser..
Post pics...
and ofcourse the silencer...

In all the time you been posting about your shotguns, I have yet to actually click on one of your threads. I don't why though, but you've made one hell of a gun and started a new trend in pnuematic weapons!

Anyway, I think it's time for me to attempt something like this. How exactly does your piston work? Does it seal off a portion of the barrel that sticks out into that tee? And how does the chamber fill up if the piston is in there? Won't it block the opening?

I hate to sound like a noob, but do you have any diagrams showing the way everything is set up in there?

are you going to take the top of the valve,cut of two plastic things,put it back together so it can turn 360* and 1 turn lets in 1 projectile?
if you are doing that it works well i did it on an old cannon.

I cut a hole in the top of the BRASS ballvalve, so no plastic things to cut.. :D
It only turns a 1/4 and ammo drops in from the top.THere is room for two marbles to trop in, so I made a restriction in the ball, to accept only one marble at a time.
THe restriction is made of a short piece of the barrel pipe, squeezed in a vice so it doesn't fit into the ball.THen I hammered it in and now it's stuck.THis to prevent the part from moving when the gun is fired.
Squeezing it in the vice deforms it just enough to stop he marble from rolling trough it.
THe magazine will be placed over the hole I cut..

No, I was thinking about a secret gun that urban ninja has been helping me with ideas for. Some clues:

Semi auto

250 psi

Will look like a real rifle

All metal

10 shot mag

Black paint job

Thankyou all.
