2 Chambers

Unread postAuthor: spud man » Thu Aug 10, 2006 2:47 pm

If you had two chambers rather then one on a pneumatic would it more powerful then if you had one chamber. And if so is it worth putting an extra chamber on.

it should be more powerful as long as you lengthen your barrel also. or else you would just be wasting air. use the ggdt

Yea two chambers will make it much more powerful as long as you dont restrict the flow and like djt said use the ggdt...

More chamber volume will decrease pressure loss during the firing cycle, increasing average pressure, and thus increasing muzzle energy.
Double chambers will increase chamber volume compared to a single chamber of the same length and diameter.

Double barrels would give you much more power, but with a longer barrel thus making the cannon less portable and harder to handle. If you want power you have to sacrifice some portability and some cash :lol: .
