Air Gun -- Shoots batteries and .50 caliber BBs!

This is likely the final version of my air gun/cannon. Added quick exhaust valve. Two different barrel styles now, as well as two different reservoirs. With paintball tank it's pressure rated to 500PSI, with steel reservoir it's good to 300PSI. All these tests used 115PSI shop air.

hey, would smaller ball valves release pressure faster/ more effieciently than bigger valves? ive messed with some 3/4 valves, but they dont seem to turn as fast as 1/2" valves. what lubricant is good in the valves?

[JonProce]

@princeofcats548

No, even with a slower turn speed, a larger valve should release the air mass quicker. Area is pi*r SQUARED, exponents do magical things.

Lets just shoot acid filled tubes at high velocities at solid objects... not the best idea ever. Ever had one blow?

[JonProce]

@riley191919

No. Batteries aren't full of liquid acid.

nice gun man, but seriously, disposing batteries like that is really bad for the environment. shame.

@JonProce Do you oil your qev. And if you do what do you use.
