Well, I do have a rather intricate plan for the propane and oxygen metering system. There also is a compressed air tank for venting so making it a hybrid will be a cinch if I ever figure out how to keep the ammo in the barrel. The pipe was some 6.75" ID that my shop had sitting outside for a long time. The rule there goes, if it's not currently being used, it's fair game to who wants it. So I used 24" for the chamber.

Back to the oxy/propane metering. I am currently making the tanks for that. They are 2.75" ID and are 12 or 15" long. Can't remember off the top of my head. The compressed air tank is the same size ID but is 24" long. Propane tank will be painted blue, oxygen red, and propane white with a re-blacking of the main cannon. I'm going to turn the cannon over to put the plugs on the bottom of it. Not sure if that will help in ignition. Oxygen and propane will be hung off the sides while the compressed air will be directly opposite of the plugs. The compressed air will be using the current 3/4" pipe in the back while the metered stuff will be going in a new hole.

All the original info I had was Here.

THe video can be found Here.


Edit: I forgot that the total cost I have in this is very little(~$5) because everything for the ignition is used stuff I had laying around. Distance is around a half mile but that's being optimistic.
