In this tutorial I'll show you how to make a high powered air gun with PVC and miscellaneous parts that you can find around your house or at your local hardware store. This gun has a low volume high pressure air tank and a short barrel to maximize the projectile's velocity. It is equipped with a modified sprinkler valve to release the pressurized air instantly. The air gun can shoot potatoes or anything that can can fit into it's 1/2' barrel.

Watch The Video:

Use gun safety; do not over-pressurize the air tank and never aim or fire projectiles at anyone or anything other than the desired target.

Can this gun kill a bird.? Can it take 150psi

I made this potato gun and It can safely take about 100 psi ... If you use nail darts and have good aim, and give it a 2.5 foot barrel it will kill a bird ... here is a link for nail darts (http://www.instructables.com/id/Reusable-Water-Resistant-BlowgunAirgun-Darts/)

What size is your sprinkler valve? 3/4in?

KyleTheCreator (author)  TrevorW2 months ago
For my air gun, I used a 1" sprinkler valve. That's what I would suggest.

I haven't really measured how much volume is in the tank but I use the psi gauge on my blow gun to check the pressure of the tank... I normally fill it to around 80 psi. If you
Make a air gun post a pic of it here in a comment. I would enjoy seeing it:D

tcharris20179 months ago

Hmm.. wondering how you would mod it to shoot water balloons.

I got it from winning a instructables contest.

Dude where did you that shirt!

Nice design but I think I would load it before charging it in case you hit the trigger while loading.

Thanks:)

Very cool build. Looks good and is fairly portable. Great work!

KyleTheCreator (author) 10 months ago
In the video I shot it at 80 psi. The heavy gauge PVC parts have a 250 psi max pressure rating... Personally, I wouldn't go too much over 100 psi.

How much pressure is too much?

Goatar11 months ago
If anyone watched myth busters last wk, they showed a longer barrel will produce more speed.

Thanks for the feedback!

nice air gun

KyleTheCreator (author) 11 months ago
That's a good question... I would give a rough estimate of around $35 for the parts and materials, plus the cost of the adhesives and paint, but it could be pretty cheap if you had some of the supplies already.
Randumb8311 months ago
Hey, I was wondering around how much did this cost.
put a cap at the end of the barrel and drill a hole. It the barrel then add a straight brake line big enough for the bbs.
KyleTheCreator (author) 11 months ago
You probably could if you used the right adapters, but I personally wouldn't recommend this because there might be too much pressure for such a small barrel diameter.

Do you think you could modify your design for plastic BBs?
