I was doing this just last year. I called it CO 2pider 3.5. I later gave up on it because it was getting a bit pricy, but it works! Drawbacks i can let you know about that i learned when i did it: If you make the connection to the canister yourself, including the connection to the one way valve, an air leak will always come up, no matter what you use. Duct tape, metal glue, super glue, epoxy. Spider44 learned that the hard way. Turns out the naturaly freezing temperature of the gas weakens the bonds and breaks up the shooter. The way I found to fix this is to modify mini CO2 bicyle pump, like the one pictured below. There are several diffents shapes and brands, but they all do pretty much the same thing. Because of the shape, this is what originally made me make the shooter into a gun shape. That way I wouldn't even have to modify it that much. It also makes it really easy to change CO2 cartridges on the go. Its pretty cheap, like 15 bucks. You can pick them up from any athletic store, like dick's sporting goods. it also comes built in with its own one-way valve. Another draw back, its hard to recharge the fluid tank. you would have to sit down, open up the shooter manualy, and pour in the fluid. not it my opinion a good idea since the tank is kinda small, and has to be refilled often. Thats why i gave up on it. Perhaps you can succeed where I failed! Use this knowledge to help you on your webshooter building journey!
