My 10 mm power air cannon

Unread postAuthor: Cartujo » Wed Jul 17, 2013 12:08 pm

I have built and check this compressed air cannon with plumbing parts. It is suited for high pressures.

Any idea of the maximum pressure it could stand safely?

Cool gun! I would feel comfortable holding that thing with 500 psi in it, and that is a conservative estimate. With a little fridge compressor and a spring-loaded mechanism on that ball valve you will notice a HUGE power increase.

Very nice first effort, but now you need a new valve ;)

You can fit a spring to your existing valve:



An exhaust type valve will be faster though, and you can get onecommercially very cheaply: forums/semi-auto-valve-for-under-20-t23626.html
