Signing UpStep 1The parts
The parts I used on this gun are pvc pipes (rated at least 400 PSI!)Including the pvc drain trap and all reducers/splicers.
All of the brass fittings need to be npt(national pipe thread)I used 3/4".
As for the stock and the barrel, the came off an old pump action bb gun, but those were just to make it cooler.
The trigger is a blow gun, and the laser sight is optional.
The most important part of this is the VORTEC BLOCK, which itself takes some time to make.

Watch the video. And listen...
What other part?
do not ever attempt to use one unless you know what you are doing! its highly dangerous and not for beginners. they can output lethal pressures i cant stress that enough! also the case around the pump is subjected to the overall system pressure. the cases can separate with potentially lethal results. there was actually a law suit where one came apart during a test at lower than the supposed rating. there has been at least one person crazy enough to do a max test on one. his was able to reach pressures in excess of 1000psi, needless to say that is an extremely dangerous thing to do. a long time ago i had one hit 750 plus psi in seconds. that was way too close to death for me. not a thing to be taken lightly in the least.
