Unread postAuthor: locksmith » Thu May 17, 2007 11:32 am

This is my latest creation and first attempt at a piston gun.It works great the piston is turned out of aluminum and has an o-ring.it has a marble barrel and i also have a 3/8 aluminum barrel that fires 3/8 ball bearings.The tank is aluminum as well.Only have had it up to 175psi but im sure she will take more the tank is made out of schedule 80 pipe.

I don't really see any dead space...

Maybe between the blowgun and the qev but since qevs take just a tiny pressure change it shouldn't be a problem. Plus the blowgun looks cooler where it is so the negligible amount of dead space is worth it.

Mea culpa, I meant "pilot volume", not "dead space" - but the bumper seems to fill most of it so great job :)
