Intro
Intro: Easy 10 Minute Airgun
easy and works well for how long it takes(check new step (# 6) )
1
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 ...
2
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 ...
3
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
4
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 ...
5
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 ...

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
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
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

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

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

this is what i did with mine
now its alot easier to pump

how much did it cost to make<br />
where can you at the valve
uhh where would i find a cork??? that size even?
could you use a half liter bottle
Hmm im gonna make a variation on this Out of scrap pieces i have
thats very cool
good idea with the cork
u gotta make a true trigger system dude!!!!
a trigger nozle for a hose works as a great trigger I just made my first air rifle and thats what I used
me 2, it works great!
This Better Work
cool :)
hey whats the power of this thing in FPS ??????
I think these measurments are wrong. its impossible to fit the 1/2 inch into the 7/8* without an expander. Help?<br/><br/>*i used a 3/4 because 7/8 doesn't exist <br/>
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.
the video on the intro doesn,t work. can you make it availiable to watch it ?
should be easy to use because you don't have to plug it in and out repeatedly.
how big is the cork?
i was told that there os no such thing as a 7/8" pvc. where did you get it?
Where is the cork again, and how do i unplug the cork?
the valves are about 2 bucks each at ace hardware, the T was $1, and all the reg. PVC is 55 cents a foot
cool, it looks like this might be able to make this with my low budget!
BTW I like the pump attached as a handle :)
ya its pretty cool
i figured out how to make shotgun shells for it.
they can shoot up to 10 6mm bbs
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
this is my pyro potato cannon
i use hairspry for fuel
cool...I haven't made one of those kind of cannons yet, because I don't feel like buying hairspray :)
haha yea that seems pretty cool even though you could blow yourself up haha!
so its like a shotgun, huh
instead of pneumatic try using flammble aerosol in the barrel with n igniter thats one o mine
can u tell me how u make the shells?
i got a t for 45cents at lowe`s.
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.
it is probably not smart to put your age on this site dude.
yea anyways
Im making this.
so
can u makea vid on how to load it because i dont know how
you put the ammo in the barrel then shoot
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..
Its a pump... something like a bicicle pump.
nice!
What kind of valve can i use and much does it cost and the cost of PVC pipe.
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.
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.
Wait, drill the hole in the cap and put the Valve in before cementing
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..
Shouldn't you use a one inch pipe as the chamber instead of a water bottle?
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
