SPECS:
2 inch T with 1 1/2 inch porting
2 inch x 30 inch chamber
sdr 21 golfball barrel x 40 inches
160 psi pressure gauge
3/4 qev pilot with 1/4 ball valve
schrader filling pilot side
I just got this piston today, does it look familiar,lol?? I wanted to put somthing together quick and this is what I came up with. I have only taken it to 80 psi so far, and let me tell you, it put a golfball at least 500 yards with ease!! Here are a few pics!! More to come soon, I am going to build a better chamber, my own piston, and a few more tricks I got up my sleeve!! I'd like to thank Gunfreak for all his help and input and Warhead for the qev idea!! Any questions about piston, refer to gunfreaks superna, lol!!!! Oh and thank you Jesse for mailing me the sdr 21 pipe!!!! And Warhead, I also have a cannon that the qev goes to too, but I have been having so much fun with this that I havnt posted it yet.

Like I said, when I finally seen what a piston valve looked like,"In my hands", and I seen up and close how it worked, everything just "Clicked!" I threw the chamber together quick, tapped a hole for the pressure gauge, got some fittings for the qev, and I had a cannon!! This was just something quick, better chamber and a few other things to come!! I just wanted to shoot it so freakin bad,lol!! Thanks again, for everything!! Ya, the qev is pretty pimp!!!

Jesse the bottom of the T is threaded, obviously "female", and the half of the 90 degree elbow in the T is threaded "male!" dink dink

Like everyone told me Jesse, go to the wiki and learn!!!! At least learn the names of the fittings, and no there is no nipple, Just a simple threaded 90 degree elbow male to the T female!!!!
