2 3" pressure chambers.
5 ball valves (alot i know i will explain)
1 sprinkler valve
2.5" tennis ball barrel (interchangable)
2 1.5" barrels (interchangable)
this is how it will work.
For single shot (using both pressure chambers at once and one barrel)
You will fill up both chambers with tire stem in back. Then close all the ballvalves at the top except for the desired barrel. then fire.
For double shot (using one chamber and one barrel at a time)
Have spud in two different barrels. Fill up both chambers then close one ball valve of the chamber. Then close ball valves of barrels except desired barrel with spud and fire. Open other chamber ball valve close other one and swith barrels to other loaded one using ball valves and fire.
You can then mix and match like do a double barrel shot and then a single shot. Or all three barrels at the same time. You could have all different size barrels you could have like a 1" a 3/4" and a 2" if you wanted to all about combinations.
