Yes, 120psi, it's all I can easily come up with. The pilot is only rated up to 120, so I'd have to brew something to go higher.
One thing to keep in mind, air has mass and drag. So, after a certain point, you can't increase velocity without going to a lighter gas, such as helium or hydrogen. But then, the fun isn't free any more! I also have NO idea what the chamber and tanks are rated for. They are made from electrical conduit.
ofcourse can't increase velocity above certain point but judging from the vid you haven't reached that point yet... it seems that your gun can handle 200 psi and possibly more.. if you want to replace the pilot valve there are several possiblilities for example: a piston valve for piloting the main valve or a 1" QEV (they are usualy rated to 150 psi but they can take more) . ohh BTW I didn't mean that it's weak I meant that it would rock if you up the pressure a little ;-)
Ok, heres the real test, take that big metal cylinder give it a tiny tip, noting special. And shoot a propane tank that u have turned on,and LIT. You must be 150 yards and under cover to do it. MAKE SHURE U VIDEO IT WITH CHEAP CAMERA lol
Great cannon, and presentation. Shot I like most isn't destructive, quite odd for this gun. Its when you shoot, and hit a couple feet in front of the door. The spray of snow looks awesome. Hopefully one of these days I will get around to making a metal cannon.
Crap, guess I should check the comments more often! The snow shots were fun to make, I too like the effect. That protion of the video was slowed 50%, just for reference. It's 900' to the door and takes an average of 1.2 sec to cross the gap. The projectile was a caulking tube with 1.5" of concrete for ballast.
nice song killer artist look up superstar but anyway FUCK! nice gun how long did it take to make? that is some dedicated shit for you to make this. very nice idea for loading 5* message me :)
It took a couple months of weekends messing around. There were no pans involved at the start. It was an idea and got bigger from there! It was a great way to stave of cabin fever and improve my welding skills.
FUCKING EXCELLENT

what are u shooting old cauking tubes?
NotEnoughProductions 2 years ago
Yes. Tubes that contained polyurethane for windshield installation are made of aluminum. Add about 1.5" of concrete for ballast.

so far this is the best pneumatic cannon ive seen. Beautiful work !!!
Blueseas4Joe 3 years ago
I think it is using about 90 - 120 psi becasue the chamber is so big and the gun is relatively weak eventhough the barrel has large diam
I hope he would up the pressure

Relatively weak? Hee hee........

Either metal caulking tubes ballasted with concrete, 2" trailer balls, or a 5" long chunk of 2" steel round stock.

In meters? No idea! I'm a yank. :-) Footage wise, I know it is over 1580 feet. Land ends there and it's water for another 1500 feet.

I'm a Yank too :)- I use the metric system for calculations, as it's much easier and quite faster.
