Air Cannon v3

Step 4 Fitting it all together

Hopefully you get the general idea from the picture of the end goal.

The longer lengths of tube are for the reservoir (2l bottle) and for the filler stem post. Ideally, everything should be in the same plane except for the gauge post. Therefore, I recommend you make attaching the reservoir the last thing you cement together. I find an angle of about 45 degrees is ideal for the gauge post - this allows your hand to naturally hold it and allows easy viewing of the gauge while refilling.

If a part has threads, do not cement. Instead - wait until after you paint (if you choose to do so) and use the Teflon tape to seal everything.

The last picture is with the optional add on. Everything AFTER the ball valve was not cemented in place. It will not be holding pressure and allows me to change my mind on what should go there (ie another 2l bottle). If anyone needs a better description, let me know and I'll take the time to go more in detail.

mod an EMPTY coleman campstove propane bottle, and i bet you could run 200-300 psi easy :-)

I was thinking the same thing, it's basically the muzzle loading, musket version of a paint ball gun. You should get one of those battery powered bicycle pumps and you'd have a much faster reload, maybe if you got a bunch of people with similar weapons, you could play some civil war style Paintball

lookslike a paint ball gun... you could probably make your own paint ball gun that looks like this.
