It's adjustable up to 20 psi. This is a little low for my meter, so I just do three quick injections. It takes more actual knob/lever turns than before, but it allows me to load much more quickly because I don't really need to keep my eye on the meter gauge. This is an actual pressure reg, not a flo...

It was in the camping section of my local Wal-Mart. There is a website on the packaging www.centurycamping.com That thing on the pipe end isn't a valve, it's just a useless spring that is probably useful when you are using this for what it's made for. Opposite of the FNPT side there is an adjustment...

It's nice eh, It's like two parts in one. 'Course now I have to go buy a new hose barb that fits this. I'm glad I can turn off the propane flow at the bottle so I won't have pressurized propane in the hose leading to my meter.

...Jumpin, one of the Latke test launchers was actually pretty close to this size. (2" diameter, but a couple inches longer) Indeed, Latke did do tests with 3 different setups... which tended to indicate that chamber size/shape doesn't have a whole lot to do with the optimum C:B ratio. (as a note, ...

Combined propane adapter and regulator

I just bought this at wal-mart. It serves both as an adjustable regulator, and it attaches directly to disposable propane bottles. It's outlet is 1/8" FNPT. It comes with a threaded pipe and some sort of white gas fitting. This is for camp stoves, but it seems like it should work great. It cost just...

Yeah, I read a tutorial on this a while ago. It wasn't a spudgun related site though. I'm planning on doing this once my first propane cylinder dies on me.

Not trying to spam. I figured it's cannon related, and people here would appreciate it. I would like to see the video too. :D

Edit: Mr. Crowley, are we allowed to have picture signatures here? It seems like very few people do it, and if it's generally considered irritating I could disable it.
