Semi Auto Ball Bearing/Battery Gun

Unread postAuthor: archie370 » Sun Oct 14, 2012 6:00 am

This is my first upload of an actual working pneumatic Gun

1/4 Copper Barrel 500mm

1/2 T for Qev

Blow Gun with epoxy fitting on the end (Pilot valve, Release valve)

3/4 Chamber(AirTank)


The copper barrel was soldiered onto the olive fitting to screw into the ball valve

The ball valve is a safety precaution so the gun doesn't accidentally go off


Initial problems: pilot valve wasn't opening the Qev so we made it bigger to release more pressure to pull the Qev back.

any questions just msg me or check out my youtube for some video footage http://www.youtube.com/user/pyroflixdigitalOne

I have made it pretty yet, this is only the functional part of the gun with the exception of the loading mechanism, which is still in progress
