Intro: AIR GUN (GAS GUN)
Step 1: MAKE VALVE CONNECTOR
You'll need to connect duster gun to Co2 bike inflator. Since it's made for bike tyre inflation, I'm using inner tubes valve as connector. Co2 cartridge pressure is very high, so you'll need to seal all the gaps tightly. I used hot glue all over to prevent air to come out.
Step 2: PLACE CARTRIDGE AND PREPARE MATERIALS
Place your Co2 cartridge into inflator. After check for air leaks. Cut desirable length barrel, and two pieces of wood.
Step 3: ASSEMBLE YOUR GUN
Using cable ties attach piece of wood at the end of air duster gun. Then in the same way attach barrel to another piece of wood.
Once that is done, connect barrel to the gun with hinges.
Step 4: LOAD AND SHOOT
First you'll need to put some rubber bands on, to secure barrel. then pull barrel down to be able to load gun with dart. Then release air from Co2 cartridge into a duster gun. PULL THE TRIGGER and shoot. :)
