Copper quick-change pressure tank
Posted: Sat May 07, 2011 2:53 pm
For my newest bbmg I was thinking about some kind of easily changeable pressure source, so instead of having one big tank that you could not change easily and would make the gun a bit unwieldy, you would have a lot of smaller quickly changeable ones in the form of some kind of "air mag" which would make the gun both; easier to carry and wield, and you could have a more compact design.
It had to be reasonably small so you could have a lot of them in a mag holder style bag, and as a result of it being small it had to hold a lot of pressure (talking about 250- 300 psi, a lot of pressure for me) so I decided to make it out of copper.
The way I made it quick change was a bit more difficult, in the end I decided to make it work like co2 canisters on air rifles work, but instead of a breakable one time seal i would use a schrader valve, that would be pushed open by a pin in the end of the chamber you insert it into as shown here:

where the beige color is my stock and the end piece is a twist on PVC cap with a o-ring extension.
The one picture I have at the moment is of the copper-removable chamber.
Any thoughts on my idea are welcome.
(Just a note - no I am not using a cloud or vortex system, I am using a more air-efficient system, which includes a more efficient reciprocating gas ram system)
