Very cool! Were the threads on the CO2 tank 1/2" or were they some odd type of threads? Also, how did you modify the valve on the CO2 tank?

Man i love this cannon...and my sweet ace discount lol. I made some wood slugs to shoot out of it tommorow. They have 13/16 gaskets on them and they seal like a champ. we will drill a hole for a nail and start tree hunting lol.

Nail didn't work out too well so we filled them with lead lol. Check it out>>> http://www.spudfiles.com/forums/viewtop ... 6fd#190182

Not bad! You probably could have piped the tank to hug the sprinkler a little more...not have the long gangly iron connection. However, a good effort overall! ....and good usage of the CO2 tank.

i said the exact same thing about the pipe!
i wanted a shorter one for it to be more sleek/portable or whatever
but sddds13 had the final decision since he worked there :(

whatev! its still pretty awesome.

i want to upgrade to a 3/4 QEV and crank up the pressure on this baby!
