Guard your stuff with this cheap, high-powered homemade air gun


Step 1: Materials

Picture of Materials
What you will need:

-Approximately 1.25 meters (4 feet) of 1/2 inch PVC pipe - you probably won't need that much but keep it just in case you mess up on a step.
-A 591 mL soft-drink bottle like what you normally drink coke out of
-A small sports pump
-PVC fittings (all 1/2 inch): 1 ball valve, 1 "T" shaped fitting and 3 elbows
-Hack saw and serrated steak knife
-Hot glue gun
-PVC bonding glue (optional)

I got all my PVC and fittings from a lumber store, not a hardware store. They only sell in 10 foot lengths so it cost me around 7 dollars (Canadian).

I think you shoul attach a metal coil to the trigger system so it will go back after you open it. Also you can use super glue for leaks

Cool. What other kind of trigger can you have.

Duct tape fixes everything... not necisarily well but it fixes.
electrical tape followed by duct tape extra holy :)
i agree duct tape all the way
yea XD roflmaool
yes it is, duct tape solves all problems... lol
Is it halve inch inside the pipe or outside diametre

Pls get back to me
Outside diameter
Instead of cutting the PVC with a hack saw and stuff can I just use my pipe cutter?

well there is one thing you should add to it and that is instead of using duck tape you should use threaded plumbling parts which will be more better than duck tape other than that everything is perfect
35Timmy4 years ago
it's better to use a threaded plumbling parts then using duck tape,adhesive, or pvp cement even combined it's easyer to use threaded valves and alot safer than posions that could pollute and besides threaded parts are more air tight and way less chances of leaks then using glue,duck tape and pvc cement which could get a hole or fade off

if using the coke bottle is going to cause issues cant you just use a larger conduit and a adapter?
can you fit nerf streamline darts into the barrel and make it fly fast
if you use half-inch pipe, then they'll fly with enough pressure. don't expect accuracy though
Depends on the size of the barrel. Don't pump it up to much though, or it will destroy the dart.

when i connect the pipe into the bottle (coke) should i put it all the way through? or just a bit?
jchan_985 years ago
would hot glue work for attaching the bottle to the pipe?

could u use electrical tape to cover the leaks? and also. how long does each of the pvc pipes need to be?
H205 years ago
don't use t he bottle
use some pvc cement or some rezin for covering the leaks ;) duct tape doesn't solve the problem for a long period of time ;) peace!
From my experience, duct tape doesn't seal the deal. I use epoxy (because I've got no silicone sealant (of which I don't know if it works)). And instead of the ring sight, use the sights that are used on grenade launchers. That gives accurate targeting at far ranges.
nice design im gonna build 1 this weekend =)

MrCrowley said that you shouldnt use PVC Cement on PVC to Coke bottles, so what do u use? super glue? Epoxy?
you can use pvc cement on bottles
no use duct tape there but use pvc cement and primer everywere else
You're using PVC cement on PTFE. You sir, are a genius.

Goodluck with that, by the way.
