Coaxial Pneumatic (Updated/Upgraded)
Posted: Tue Apr 08, 2014 5:37 pm
I attempted this a while ago but never finished it because I had no idea what to use as a piston (I first tried using some PVC fitting wrapped in tape but that didn't work at all). After a while I finally got a working piston and I have to say this thing is LOUD, my first shot was at 40 PSI, no projectile or suppressor and it was earsplitting (then again I did it inside). I went outside to test it at 60 PSI with a wax slug against sheet metal and was surprised by the pure power of the piston valve.
Anyway a few specs:
-2" piston
-1/2'' Ball valve pilot valve (I want to upgrade this later)
-.75 caliber barrel, I think it's about 18'' long
-.75 caliber suppressor (want to upgrade this too)
-Minimum operating pressure: about 20 PSI
-Maximum operating pressure: about 150 PSI
That's all I can think of
It's pretty noobish but I love this thing so far. Any recommendations welcomed
UPDATE:
-The pilot is now a 3/4'' sprinkler valve and the pilot for that is a blow gun
-Minimum operating pressure: about 10 PSI
It's louder than originally, but seems a bit better functioning, new pictures at way bottom
