Mini Barrel Sealer

Unread postAuthor: Vanlandinghale » Sun Oct 28, 2007 12:01 am

While my big cannon project is delayed waiting for parts to ship I thought I'd see if I could make a little one out of spare parts. Here's what I came up with, its a little barrel sealer with a 3/4" chamber and a 1/2" barrel. Didn't have any little bushings so I dremeled out some reducer couplings. When the glue's all the way dry I'll test it some more and put up a video.

Thats pretty smooth, post some pics of the piston so we can drool over its smallness. Even though its in a 3/4" tee its still pretty amazing that piloting from a blow valve is effective.

Again nice use of extra rubber and extra pipe.

Get a longer barrel and shoot some double a's

Looks way cooler that a sprinkler valve, most people are lazy and use that for a smaller gun..

Peace,

Thats pretty sweet for a spare parts gun. Very nice, thoguht the barrel could be longer.
I am really interested in what the piston is though.
