Hey everyone, this is my first air gun, the Arbitrary Object Displacement Device or AODD-1 (name thought up between my roomate and i).

The original intent of this gun was to make it a net gun, but ive spent too much money on it already and didnt have enough to go get a net/weight system.

Its a bit messy, and not that well thought out, but I didnt start building it until friday at like midnight, and I finally just finished this afternoon.

It uses a 2 inch barrel, and same size chamber. I wanted the option of firing alot of different ammo, and 2 seemed to be the right fit. The valve is a rainbird modified with a blowgun. Fill valve is a schrader drilled into the endcap and sealed with rtv silicone. Everything else is sealed with cement, except the blowgun where I used epoxy.

I can only get it up to 65-70 psi before the bikepump i have starts to blow air in my face, but even then the thing launches a potato effortlessly across a pretty good sized baseball field.

I have a small leak somewhere in the reducers for the gauge (might even be the gauge thread) So next weekend ill try to fix that.

Input, ideas for further improvement, and criticism is all welcome

Is there even a nipple connecting the blowgun to the valve?

yeah theres a threaded 1/4 inch piece that i drilled into the platic of the valve and screwed the blowgun onto. The blowgun threads leaked like crazy at first so i epoxied them up, put it on and let it dry, which is why it looks so messy haha.

Did you happen to use teflon tape? It helps seal imperfections in the threads and will also help thicken the piece up a bit to fill in small gaps.

yeah i tried that first, it just wasnt happy with it

Oh well alrighty then
