AIR CANNON
Intro: AIR CANNON
Here is an air cannon I made with on old air compressor tank and some other junk I had lying around. The only cost to me was the ball valve that cost about $50.
I may need to move the pressure gauge to another available port that is not on the fill stem, I'm not sure if I am getting a true read.
The entire gun is made from steel and brass except for the barrel that is after the ball valve is PVC to reduce some weight.
I am also still working on an elevator to move the muzzle up and down for more accurate shots.I thought of using a screw/scissor jack but I think It may be too bulky and slow. I am open to suggestions if anyone wants to contribute....

Probably a little too late to reply considering you're four years older than then but here's a formula to help you find the speed and then you can use that to find the amount of joules it would produce:
Speed = sq root ( (2 x length of pipe x PSI x Pi x r2) / mass)

Did you weld the attachment on the end for the valve and barrel? I'm working on a bait caster and your design looks better than my PVC model.

This is awesome. Have a tee in the barrel and use round ammo that will slide freely in the pipe. If t he tee has a small curve, have it curve toward the valve. Drop in lots of ammo into a pipe connected to the arm of the tee. Make sure the tee is right after the thread adapter. You may end up shooting several projectiles at once! Use a clean-out adapter and a plug at the end of the clip. It really works.

Starting on the bait bullets next! No more tempting the great whites seen around here lately when wading out to shoulder depth in the surf to get a better cast. :-)

Upgrade. Affix a pointer on the sleeve aimed at a protractor on a stationary upright and it would be possible to dial in a target with a few rounds or consistently hit a target if the distance to target is known. I'm sure there's some one with artillery experience would have even better ideas.
