Hi all ! i've already 2 cannons in the other topic so i do antother this time.
During my holiday, i'm bored sometimes, and want absolutly build a new cannon don't matter which.
So, without buy anything, i made a pneumatic cannon, it's not very beautiful and etc.. but nice
It's a 10mm caliber, for a pressure to 500psi
Actual pisctures :

Only 50 psi???I would go up to 180 psi if all parts are metal.

Doctore has a point, you can go way past 50psi with that kind of construction, why not?

Can you connect a sprinkler valve to a metal gun like this one?

Sure you can.
People generally use QEV on a full metal construction
and people whom use PVC generally use a sprinkler valve.
It's up to the builder i guess.
Anyway, on topic
The gun seems good for a spare part gun.

Yes and QEV is more efficient, realasing the air faster than a sprinkler vavle
And if wa take right parts, we can up to 600psi or more.
It's it's the ball valve, with a spring
Yes, well enought, but i'm limited by the handle, it twits when i load the spring...
