Introduction: How to Make an Air Gun

HOW TO MAKE AN AIR GUN IN 5 SIMPLE STEPS

MATERIALS:
1 BOTTLE
1 GAGE
1 LONG PIPE
1 HOSE GUN OR AIR LINE FITTING
1 COPPER PIPE
1 CONNECTOR (BOTTLE TO PIPE)
1 BIKE VALVE

Step 1: Makeing the Air Chamber

FIRST GET THE BOTTLE AND THE BIKE VALVE. DRILL A HOLE IN THEN BOTTLE BIG ENOUGH FOR THE BIKE VALVE TO FIT THROUGH THEN DROP THE BIKE VALVE IN THE BOTTLE THEN POKE IT THROUGH THE HOLE GLUE THE BIKE VALVE SO AIR CANT GET THROUGH OR YOU CAN USE PVC PIPE INSTEAD OF A BOTTLE.

Step 2: Putting the Gage On

DRILL A HOLE I THE SIDE OF THE BOTTLE AND THEN PUT A BIT OF GLUE AROUND THE EDGE THEN SCREW THE GAGE ON (THE GLUE IS TO GIVE THE GAGE MORE SUPPORT AND MAKE SURE THE AIR DOESN’T COME OUT)

Step 3: Connecting the Pipe to the Bottle

GLUE THE CONNECTOR IN THE END OF THE BOTTLE THEN PUT A BIT OF GLUE AROUND THE END OF THE CONNECTOR THEN PUT THE PIPE ON TO IT

Step 4: Connecting the Trigger to the Pipe

CONNECT THE END OF THE PIPE TO THE HOSE GUN OR AIR LINE CONNECTOR

Step 5: Connecting the Barrel to the Gun

CONNECT THE COPPER PIPE TO THE HOSE GUN OR AIR LINE CONNECTOR I USED A PIECE OF RUBBER PIPE TO CONNECT THE AIR LINE CONNECTOR TO THE COPPER PIPE BECAUSE IT WOULDN'T FIT STRAIT ON.

Step 6: How to Use It

PUMP THE BOTTLE UP AS MUCH AS YOU WANT USING THE BIKE VALVE AND A PUMP THEN PUT SOMETHING IN THE BARREL THEN PRESS THE TRIGGER

Jeez, could your pictures be any blurrier?! And whats with the caps lock? please, try to be a little more informative, and not sound like your yelling all the instructions at everyone. I'm surprised this hasn't been confronted by the admins. I like your ible, it just needs alot more work before you publish.

Lol, dude, add a disclaimer and a warning. Just in case someone got one explode in his face and went to the hospital and point the finger at you (aka. you get sued).

I don't have the patience to pump huge guns, I love small pneumatic guns, and large combustion guns

HOW DID U MAKE THE BOTTLE SMALLER?

author
stephenniall (author)sharlston2009-04-27

You cut a slit down the middle Put it over the Other bottle and put a blow torcg (or lighter) near it so it melts it but not to a extent the plastic burns And spin it very slowly it will eventually melt

Could I make a suggestion in the name of public safety?.. Dude tape and relatively high pressures don't mix... I get the shakes when I get my galvanised/copper fitting rifle up to 90PSi. If that coke bottle goes, then so's the side of your face.. NOTE TO ALL: Coke bottles are NOT pressure rated! Yes you can get them to 145Psi before they NORMALLY blow up... BUT there is just too many variables... eg.. Heat of plastic, deterioration factor, physical damage... These factors exclude these vessels from having a PSI rating.. If your going to the efforts of making this please .. go to a plumbing shop and get pressure rated fittings.... Then happy shooting!!

author
receiver545 (author)Lftndbt2007-10-29

yes coke bottles are pressure rated !!! call them and ask for the max psi they will tell you for a 2L bottle that it is 200psi for a non stressed bottle, for stressed it 150psi (and when i same sressed i mean like theres a hole made in it then patched!!

well nice work but instead of using a bottle us 2in. pvc !! its max psi is 600 so you want have to worry with it blowing up !!! and before you buy any check its max psi take the one with the greatest max psi!! and the put the valve in it !!!!!

have fun shooting !!!!'

It's really ironic... You don't capitalize the title etc, but you write everything that doesn't need to be in caps with capslock on...

MAYBE HIS CAPS-LOCK KEY IS BROKEN. TOO BAD IT WAS STUCK IN THE ON POSITION WHEN IT BROKE.

author
T3h_Muffinator (author)locofocos2007-04-21

Broken? If you're missing the key use a pen to push the rubber button down. If your keyboard is broken tape down the shift key so that your font isn't in caps... OR just buy a new keyboard... they're pretty cheap....

You appear to have used some kind of Sellotape(R)?
Tut, tut. Examples of acceptable tapes include:
Duck(R) Tape
duct tape
Gaffer tape

jay, you don't know what you are doing a blow gun like that doesn't have nearly enough flow to power a gun with a barrel size like yours and that thing is not gonna take a 100 psi charge without something giving and did you make 2 accounts just so it will show up as a collaboration?!

author

And WTF you didn't even use hose clamps on those tubes!!!!!!!!!!

btw a soda bottle can take anywhere between 50 to 160 psi
