Introduction: Easy 10 Minute Airgun



easy and works well for how long it takes

(check new step (# 6) )

Step 1: Materials

you will need:

2 liter bottle
bike pump (with needle)
cork
two 7/8" PVC valves
one 7/8" PVC "T"
one piece of 7/8" PVC 1/2" long
two pieces of 1/2" PVC 1 1/2" long
two pieces of 1/2" PVC 2 1/2" long
one piece of 1/2" PVC at least 2 feet

Step 2: Construction

using pvc cement, put the pieces together as shown in step 1 picture.

IMPORTANT:
make sure to glue all pieces EXEPT the barrel! do NOT glue the barrel to the valve as you will be taking it off to reload

Step 3: Pump

drill a 5 mm hole down 3/4 into the cork

after that, stick the pump needle into the other end all the way

Step 4: Load Projectile

take the barrel out of the valve and put your bullet in the end
(i used a marble wrapped in masking tape)

make sure its a tight fit or it might not work very well

Step 5: Launch

to launch, make sure that the valve on the handle is open and the valve leading to the barrel is closed.

then stick the cork into the bottom of the handle and pump it up.
(i usually pump 5-7 times)

when you're done pumping close the valve in the handle and unplug the cork.

after that just open the barrel valve and your projectile goes flying

Step 6: Expand on the Design

once you get the basic design down, expand on the idea!

this is what i did with mine

now its alot easier to pump

where can you at the valve

aljh (author)2009-08-25

uhh where would i find a cork??? that size even?

author
li789 (author)2009-08-17

could you use a half liter bottle

author
stephenniall (author)2009-04-15

Hmm im gonna make a variation on this Out of scrap pieces i have

author
yamiyobi (author)2009-03-23

thats very cool good idea with the cork

author
fireFEIND67 (author)2007-09-21

u gotta make a true trigger system dude!!!!

author
milamber (author)fireFEIND672008-12-05

a trigger nozle for a hose works as a great trigger I just made my first air rifle and thats what I used

author

me 2, it works great!

hey whats the power of this thing in FPS ??????

author
seymourpatrick (author)2008-10-22

I think these measurments are wrong. its impossible to fit the 1/2 inch into the 7/8* without an expander. Help?

*i used a 3/4 because 7/8 doesn't exist

author
Bugman9 (author)2008-10-21

how do you put the bottle on? do you put pvc cement on? i even put the bottle all the way on and it leaks air.

author
Bugman9 (author)2008-10-20

the video on the intro doesn,t work. can you make it availiable to watch it ?

author
Bugman9 (author)2008-10-19

should be easy to use because you don't have to plug it in and out repeatedly.

author
Bugman9 (author)2008-10-19

how big is the cork?

author
Bugman9 (author)2008-10-19

i was told that there os no such thing as a 7/8" pvc. where did you get it?

author
kburesh (author)2008-09-27

Where is the cork again, and how do i unplug the cork?

author
eshimo (author)2007-08-07

the valves are about 2 bucks each at ace hardware, the T was $1, and all the reg. PVC is 55 cents a foot

author
-insertnamehere- (author)eshimo2007-08-08

cool, it looks like this might be able to make this with my low budget! BTW I like the pump attached as a handle :)

author
eshimo (author)-insertnamehere-2007-08-08

ya its pretty cool i figured out how to make shotgun shells for it. they can shoot up to 10 6mm bbs

author
-insertnamehere- (author)eshimo2007-08-08

I want to make your gun, because my current one is not very portable at all....but it can shoot 200 6mm airsoft bbs at once :). Also, it takes about 150 pumps to pump it up :( the tank is 4" PVC and is 4 feet long. I have two interchangeable barrels, one made with 1.5" and the other with 2", each five feet long. reaallllly heavy :P

-insertnamehere- (author)eshimo2007-08-09

cool...I haven't made one of those kind of cannons yet, because I don't feel like buying hairspray :)

author

haha yea that seems pretty cool even though you could blow yourself up haha!

author

so its like a shotgun, huh

author
eshimo (author)-insertnamehere-2007-08-09

instead of pneumatic try using flammble aerosol in the barrel with n igniter thats one o mine

author

can u tell me how u make the shells?

author
pandaboy292 (author)eshimo2008-04-13

i got a t for 45cents at lowe`s.

shooter1 (author)2007-08-15

Mate you done a great job of this one i am only 11 and trying to make something like this and put it on this website.

author
kicker109 (author)shooter12008-07-12

it is probably not smart to put your age on this site dude.

author
guitar2damax (author)kicker1092008-07-16

yea anyways

author
shooter1 (author)2007-08-15

Im making this.

author
kicker109 (author)shooter12008-07-12

so

author
kirkdarida (author)2008-03-27

can u makea vid on how to load it because i dont know how

author
kicker109 (author)kirkdarida2008-07-12

you put the ammo in the barrel then shoot

author
blugyblug (author)2008-02-10

Im gonna make something like this, except safer 0o...About step 6. Wat is attached to the cannon? It looks like a syringe ...and how are u supposed to pump with it? You have to take it off, Get some are in, put it back in and push the air out...then u have to repeat..

author
biolethal (author)blugyblug2008-06-28

Its a pump... something like a bicicle pump.

What kind of valve can i use and much does it cost and the cost of PVC pipe.

author
Rishnai (author)SnakeFang2172008-03-23

Really, anything that fits your pipe. I'm partial to the sort of thing with a wheel like a garden faucet would have for my cannons, mostly for looks and controllable air release (not all or nothing). If you just want one valve, get quick-release, but if you want to be able to charge once and fire a few times, get a wheel valve, a chamber, and a quick-dump valve. Charge the chamber with the desired amount, then flip the quick-dump to fire. Anyway, I'm overcomplicating. Any kind of valve works, but the less turns it takes to open, the closer to maximum velocity you'll get. The kind like he shows in the pictures are awful darn inexpensive, by the way.

How do you pressure rate it because I don't want pvc being dug out of my flesh.

author
Rishnai (author)SnakeFang2172008-03-23

You don't oressure rate it, the factory does. They test it with compressed air until it blows. The pressure rating for a batch is the minimum allowable failure point. Even if you buy non-pressure-rated tubing it may not blow, but if you test a few samples and they hold up, it won't mean that the next one won't go KABOOM. Ask the Home Depot man for "pressure-rated-PVC tubing" and he'll show you the stuff that won't cause that nasty skin condition you describe.

blugyblug (author)2008-02-15

Wait, drill the hole in the cap and put the Valve in before cementing

author
blugyblug (author)2008-02-14

And i agree with Gene Hacker, get an End Cap that fits the handle as well as a tire Valve. Cement the Cap on and when it has dried, drill a hole like 1 mm smaller than the tire valve and shove it in. Use Hot glue, super glue, epoxy, PVC, Cement and everything to seal it in..?

When plastics fracture/explode depending on there make-up, they can shatter into tiny tiny shardes similar to glass. Unfortunatley scans generally can only pick-up the larger shardes leaving the doctors to slice your face up trying to find the rest... Please, given that you haven't followed general saftey guildlines whilst building this perhaps a saftey caution would be a good idea... Just for the kiddies sake..

gaara0sama1 (author)2007-12-31

Shouldn't you use a one inch pipe as the chamber instead of a water bottle?

author
frankinator (author)gaara0sama12008-01-21

water bottles hold a surprising amount of air I've done test with air compressers with them in a metal box and they failed at 210 psi

how far does it shoot
