so i forgot to take pictures whail i was building it today but i figured id post up a how to on my air cannon take tho it is not compleat yet i still have to do the electronics box i will take pictures of that whenever i get some solder
this is the compleat product minus elec box and remot hose
i used 2"pvc scd 40 pipe that is pressur rated for the barrel i then put it to a coupler and used a 2" to 1" reducer (the 1" is threaded)
hear i used a 1" nipple between the barrel and sprinkler valve so i can change barrels out later if i decide to change it ever
this is the sprinkler valve i am useing it is 18volt and solenoid driven it has a 1" nipple on eaither end
hear we have a 1" nipple going to a 1"t fitting with 1" to 1/2" reducer and then 1/2" to 1/4" reducer with a 1/4" nipple in the end of it
ok her is the end of the metal piece the 1/4" nipple goes to a 1/4" t fitting and on top i put my guage so it would look kind of like a sight and i would easily be able to moniter the pressures in my cannon. on the bottom i put a 75lb pop off valve so i can not over presurize the cylinder i am not shure if i will need more then 75lbs of pressur but i figured it was a good starting point and a verry good saftey feature on top of the regulator.
