Super-small chamber fan inspires me to....

... design a combustion sniper gun. Probably silenced. I'm thinking 3/4" sch. 80 barrel to take paint balls and patched marbles. Maybe bolt action? I've started sketching some designs. Definitely metered propane! I found some small propane tanks but I want to get one first and play around with it and make sure I can get the fittings to make it work. Probably a 2" chamber, shooting for a .7:1 C:B and then a large silencer... I want this one to sound no louder than a mouse fart.

I'll post updates as this comes along.

Cute little fan does about 5000 RPM at 9 volts...

Sounds fun already. The fan should work great.

Maybe you could try an external syringe injected propane system of some sort instead of trying to mount a propane tank onto that size gun.

Keep us posted.
