Looking good. Are you planning on just using the switches on the stun gun as your ignition? If not it's really easy to wire in a momentary switch and an on/off switch as a safety. It makes for a great way to have easy ignition using handles. Also, Definitely dremel down those spark gap test leads......

the stunguns case is probably fused together. I used a dremel to cut around the fused edge all the way around the gun. Then you just pull it apart. It's bettter to do it this way because you can take the guts out and wire it however you want. I added a saftey and momentary button as a trigger. Also ...

No. No hose and definately no super glue. Take time do it right.

Check out my sig. As combustion monkey said, a 90 elbow two ball valves and a nipple for your meter is the base of the system. My gun has an onboard metered propane setup. I have since upgraded to a Husky pressure gauge/regulator and now the whole setup self regulates the exact PSI my gun needs to o...

Man I gotta know, where do people get all these old gun stocks? It's just amazing to me that so many people just have busted up old guns lying around their houses.

Well propane is heavier than air. So when you inject proane in any chamber it technically sinks to the bottom. The fan would begin circulating inside and move the propane and air together spreading said propane in the chamber. Uh... No. Propane will not "sink to the bottom" it will disperse evenly ...

how does it shoot?

Best spray and pray propellants are carb cleaner and butane. For smaller guns butane is great, for gigantic guns carb cleaner. But starman is right, if you want to get serious about combustion metered is the way to go.

Ahh I see, you are relying on the air fitting to approximate the fuel air mixture necessary to ignite.

interesting video, you seem to slam that ball in place pretty quick, what's the reason for that? Does it mix the fuel? I don't understand, are you metering your fuel?

Is your Leatherman the "all you can eat" variety like I have? You know the ones with with a file, screwdriver, flux capacitor, etc etc.

You're all against me.

A man was killed when his cleanout cap blew off and hit him in the chest using a 'spray and pray' combustion IIRC. He died of a heart attack or something. Spray and Pray's only generate about 40PSI. I think even less then that. Ok I don't doubt that a man was killed with a clean out cap, but probab...

Wow. Fantastic collection.
