Step 1: Materials

Picture of Materials
you will need:

2 liter bottle
bike pump (with needle)
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

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

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

Picture of 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

Picture of 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

Picture of 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

Picture of 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

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?

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

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 ?
Bugman96 years ago
should be easy to use because you don't have to plug it in and out repeatedly.
Bugman96 years ago

Bugman96 years ago

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

eshimo (author)  -insertnamehere-8 years ago

blugyblug7 years ago
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.
