Hey, I'm back after a slight hiatus from spudding due to my pockets being emptied from my copper piston gun. I've built mainly pneumatics, and kinda skipped combustions (I've made your generic one, but I'd like to make an advanced one).

My question is, where do I find a pressure regulator for propane that is adjustable? I've seen flow regulators, but I can't seem to find a pressure regulator that is adjustable. Any pics, links, or information is appreciated.

Later

the ones from BBQa are adjustable, but propane is only charged ate around 90-130 psi, depending on tempature, so you really dont need one.

also, if you use a blow tourch then you will get exactly howmuch pressure you want because it comes out slow enough you can shut it off.

Thanks for the info, but I'm looking for a regulator like the ones used for CO2, nitrogen, etc. These are adjustable to a certain output. Do these even exist for propane? Could I use one intended for CO2 for propane?

You can use a air regulator for a propane meter.
They work fine.

Just use the ones you find on air compressors, they're pretty cheap I got mine for about $9NZD($7USD)

yeah usally a mini air regulator works but fixed regulators are the most reliable

Before you get a regulator, try the classic standard meter with two ball valves and a PSI gauge. If you're reasonably quick on the valves (close the meter pipe off when the gauge hits the desired PSI) you'll get perfect mixtures without needing a regulator. That's what I use on my "advanced" combustion gun. You can always add in the regulator later.

Peace,
