truemanator said he likes simple cannons. Here's the problem to get a powerful combustion you need to build an advanced combustion or hybrid, both of which are inherently not simple (hence the name advanced combustion) :lol: But if you want power AND simplicity, a pneumatic cannon is just the thing....

If you want to do a pneumatic cannon, then the recipe is simple: Air chamber (same as combustion chamber) ball valve, barrel. No seals required. And very powerful. In fact you can simply Google ball valve air cannon, and people have made diagrams and stuff for these guns. Also don't worry about pis...

Nice, good job on the CAD. But if you are looking for simple and lots of power, then BUILD A PNEUMATIC CANNON! :D

EDIT: Apparently you already did, oops :oops:

No, but I still have the fill valve to deal with, and I built this gun mostly out of PVC so it isn't perfectly compact. Plus I didn't even know I had a problem when I built the gun.

Lucky AK47, I wish I had 40000 PSI to play around with. :D Plus an AK47 has to push the bolt back very far compared to this gun.
