I was planning to make one with a barrel about 10 ft and chamber about 8 ft using rainbird solenoid valve like on a p.a.c cannon but due to lack of resources I couldn't. And I am planning a special loader smaller than revolver X and easier than auto loaders. WINK WINK NUDGE NUDGE SAY NO MORE :D

Make your barrel longer - a .7:1 or .6:1 chamber:barrel <i>volume</i> ratio will make it quite quiet.

i've got an idea to use 4 air tanks of 4 feet long, and have a 10 foot barrel
tanks about 3 inche in diameter ,
barrel about 1/2 inch in diameter
the tanks would be positioned in a square pattern, and the barrel coming through the middle.

3quarters - that would be a utter waste of tank volume. Now, a system with 2" ball valves and (duel?) supah(s) feeding a 3" barrel, breach loading would be cool - it'd allow you to fire off up to 4 shots in fairly rapid order.

im trying to design a full auto magazine for a repeating-style pneumatic. It would be of single barrel design attached to two independently operating chambers that fill and dump air in opposition to each other.

Schematically this is possible, through a system of electronically operated solenoids, so that isnt the problem.

Ive been looking through this thread and havent really found any good brainstorming ideas, so here is one;

:..: "Using only PVC, brass or copper fittings, and using a minimum of machining, how could we design a gravity, or spring fed magazine?"


Anyways, my idea so far is limited to a design closely resembling that of a paintball repeater, however i fear that this would require skills in machining that i do not have or do not have access to.

If anyone knows of prior posts about full auto cannons please point me in their direction[/u]
