Busrt disk isn't going to happen for me, too little control. I think I will try to use 2 pneumatically actuated 2" ball valves and a larger chamber to compensate.

Welding is no problem, that's why I'm doing it out of steel.

I haven't read anything on the burst disk valve, I just glanced over a few illustrations, but aren't they one time use? I need something that will facilitate fairly rapid fire. I'm considering a steel 2" ball valve actuated with a pneumatic ram, has this been done before?

I am in the planning stage of a new cannon. I want it to be built of steel, with a 4"x14" air chamber and a 2"x 96" barrel. I plan on using the gun at about 500 PSI via a SCUBA tank. What kind of valve could I use that will handle the pressure?

i thought it was glued in, it felt kinda hard to remove

it was glued in from the factory, what do i use to glue it back

how do you get the diphragm to stay back inafter the mod?

how do i get the diaphragm to stay in? its a lawn genie 54004
