bolt action test

Unread postAuthor: urgle the danish cow » Wed Dec 15, 2010 9:59 pm

ok sorry about the primitive ball valve but the purpose of this gun was to experiment with a bolt action
air chamber: 2 litre bottle epoxied to pvc.
barrel: 1/2 inch pvc
bolt housing: 1 inch pvc
valve: 1/2 inch ball valve :(
the power is decent and i can open the valve reasonably fast.
main ammo is AA batteries
i didn't trust my copper cutting skills to try the bolt in copper which probably would have been better. but layers of duct tape with smooth ends gives a snug and smooth bolt
please provide feed back on the bolt
