The two fittings you have, the one on your propane tank and the one on your actual gun, are those your normal run of the mill air fittings? Or are those some heavy duty ones?

Those are standard air fittings that have been sealed by using teflon tape and plenty of torque. The air pump inlet on the cannon is a regular air tank shrader valve.

Absolutely beautiful!! It's Planning / design, selection materials & finish and quality of craftsmanship is obvious to the most casual observer. Excellent!

Hey thanks man! It was a fun project to work on for sure. The guys who welded it must have done something right since it hasn't blown up in my face yet :lol:

A shot cup with a bottle's worth (5-10k) copperhead BBs would (likely at 2x) shred virtually anything in front of it. I would do it from a bunker though, the ricochet of 10k BBs could be quite devastating to everything in your target's reverse radius LOL.

I did something like that and ricochet they did! They didn't come back very fast though. They didn't even get to the target very fast, I think I needed a better sabot. I used a cardboard tube and paper wadding for them and I think a lot of air blasted around the BBs.

Amazing build. I don't like how you rerouted the direction of the gases going from the chamber to the barrel. I guess it makes it more compact, but still I'm all about power. It's better than anything I'll be making anytime soon. Overall great gun.

Another cannon that I called the "Cobra Striker" won second place for innovation. That cannon ultimately failed completely. It sucked because I didn't machine anything so I couldn't machine any proper seals for it and I couldn't make a proper piston. Also, I used pure O2 and the seals ended up catching on fire, lol. It was a mess. Hopefully my new design will be better.
Good to see you. Wish me luck on my new 10 year anniversary cannon I'm working on. It has special significance.
