Hiya,
I'm planning on building a new airgun and I was wanting to get some help on its design, so I'll explain what I'm planning on doing. Ok first please look at the picture, Now I fill the main tank and valve-1 stops air getting into the Firing tank. Valve-1 is linked to the bolt action mechinism so that when the bolt is opened the valve is opened when it's closed the valve is closed. So I Open the bolt to put the bullet in and the firing tank is filled with air, I close the bolt and it closes valve-1 so the main tank is blocked off , then I open valve-2 to to fire. This way you get multiple shots.
The picture is useless so the valve closesest to the right is valve-1, The one closest to the left is valve-2. The smallest chamber is the Firing Chamber, The biggest The Main Chamber.

Thanks,
Mattrox
