Im planing to start building my spud rifle as soon as i finish the school exams, but i've already started buying the stuff, part of it. And i have a question.
I found a car paiting set which uses pressurised air in a small tank which can hold up to 170psi, so i was wondering how much power cant that give ? In projectile speed. Im using a barrel whit the similiar size of a paintball, whit 1m long.

The hole idea is to build a equivalent to a paint ball marquer would those 170psi match it ?

Thanks

170psi would far exceed the speed of a pb gun, and it would also break someone's goggles or ribs if you shot them with it, which is why people never shoot others with cannons. the performance depends on the valve, download GGDT and fool around with it, also you need a valve that can handle 170 psi, most cant

well, he could use a ball valve, but it would be better to just go to 100psi with a sprinkler
