Propane & Lever-Blowgun

has anyone tried using blowguns on a propane meter? i think it would be really cool to have two blowguns but it never hear about anyone doing it so there's probably some sort of safety issue i'm overlooking. I know that they often aren't rated above ninety psi, but past a regulator that is no problem. any other issues i'm not seeing? any first hand experience? any on-the-spot speculation?

I think that could work, but I have had a few blowguns that leak. Also, If you drop the gun or lean it against something the blowgun might open. Meters just seem sturdier and safer with ball valves.

i do agree
even though they are slower they are more reliable

I usually have a little blowby on near the trigger. You could spray the trigger with soapy water to see if it leaks any. Man that would suck....pshhht...pshhht....CLICKBOOOOM!!! AHHHHHH MY FACE!!!!

i love star trek, lol
anyback on topic, um maybe we could figure out a way it increase the blowguns performance so that it could be used for this application

I've used it on mine, though I never finished the gun it was for....
It held the pressure fine, and no damage was done to anything.

i might try this if i ever get around to making a combustion. It might be a good i dea to put a safety ball valve infront of first blow gun just encase the metering thing does not get turned off completely.

Any valve that can handle the pressure (after a regulator that shouldn't be a real problem anyway) and cold temperature of (potentially liquid) propane should work, so yes it could be done.
The problems I see are, as jssizzle pointed out, the risk of accidentally opening the valve(s), and the fact that it would really only be practical on a small cannon (one small enough to use 1/4" for the meter pipe...).
If you decide to try it, let us know how it ends up.
Peace,
Pete Zaria.

what about the 1/8" output, I have trouble getting a good seal on 1/8" threads these pinholes leaks keep popping out from the Teflon tape seal

Teflon tape, or paste will work.
