My La France pnuematic.

Well this is my third spud gun. I aquired a fire extinguisher and i wanted to use it for the tank. The treads oin the tanks were metric but i screwed in a 1 inch male bushing and it seems to be ok. I modded a sprinkler valve for the first time which was a success. Everything went together ok and i made it with a 1.5" barrel, and a 1 inch barrel. It is going to be a bolt-action ping-pong ball launcher. But i need a coupler before i can put it on the barrel. Tommorow im going to go to the store and pick up the coupling then it should be totally done. Here are the pics-
The brand of the fire extinguisher is a american la france...hence the name.
Here is the bolt-action repair coupling-
the coupling slides so i can slide it open, drill a hole for the ping pong ball then close it. So when i need to load, i open the slider put the ball into the hole then close it...it is completly sealed with o- rings too

EDIT: Kinda just test fired it... i filled it up with 20 psi, loaded a snowball into the barrel pulled the trigger HONK!!! ok, disassembled it, lubed the diaphram...take 2...pulled the trigger whoooosh tossed the snowball like 50 feet. With a ball valve at 20 psi it would barely blow it out of the barrel. awesome power.

Viva La France I say...
That breechloader might be quite a find.
The colours suggest it's Italian by the way...

One thing..wouldn't a PVC chamber be lighter or is the weight of the bottle okay?

[saladtossser]

pretty damn sweet, what fittings do u use to hook up the bottle?

[Mr_SBC]

just a 1 inch threaded bushing kinded jammed in there, o and the bottle isnt really for perfomance at all, mainly for safety and looks.

Well i FINALLY got my sdr-21 from the local hardware store so i got my golf ball barrel done. Ive been shooting it at 120 psi latly and it shoots so well. I shot a golfball through 2 peices of 3/4" chipboard nailed together. my combustion will shoot through one...
