Tracy are you referring to the needle valve ? If so the actual valve is left handed as in clockwise to shut off and counter clockwise to open,the valve body itself is standard 1/4 mpt and 1/4 ftp .good video.
I really need to finish my ribbon burner. I have the metal shell already and the castable. I need to go to get a fist full of straws and get it done.
I have been saving a small propane tank for this. Is the valve on the top right hand or left hand threads - do you recall?

First off Wayne I didn't think it was all that complicated,I have a 1/4 inch ball valve in hand for the quick gas shut off and as far as the pressure regulator valve being a problem it's not I was just pointing out that it has a check valve in it .Someone might think they have a bad regulator without this info.And besides as Elvis once said I Did It My Waaaaay !That Is the most complicated way that I have seen to set up a Ribbon Burner forge. But it is one way to do it and it is not "wrong".
1st there should be a ball valve just before the needle valve for fast on/off
2nd all connections can easily be made with npt parts readily available at any hardware store. No soldering.
3rd use the correct regulator. You should not have the problems described in the video. Once you have adjusted the air/gas mixture there should be very little need to adjust the air/gas mixture. I only adjust the needle valve when I want to reduce or increase the temp in the forge.
4th no need for a "mixer" if you just run the gas directly into the larger pipe (air/gas )you will get plenty of mixing
5th ALL WAYS turn the gas on/off valve all the way on.
6th remember that Propane is heavier than air. Natural gas is lighter than air.
If Propane turn the blower on first. If natural gas don't worry about it unless the blower is plumbed above the gas inlet.
I run my forge at .5 pounds of pressure for forge welding, with no flux. I do use a pyrometer to 2015degrees with the dragon's breath extending about 6" out of the forge.
Let me know if I can help you. You can find my contact information on my Profiles page. I prefer e-mails.

I think Tracy is talking about the whole valve on top: right or left threads when unscrewing it off the tank? I've done it twice but can't remember either.Ok so the hose and valve assembly that goes on your propane tank.The black ring that attaches to the tank is right handed,the red knob that opens and closes the valve is left handed as in clockwise opens the valve and counterclockwise closes the valve.
Oh I got it now ! The main propane tank valve has right handed thread's, I had to ratchet strap my tank to a tree and use a 3 foot pipe wrench to get it to turn lol.I think Tracy is talking about the whole valve on top: right or left threads when unscrewing it off the tank?
