Sticky time. Doug has bared his soul, and having set up for propane a long time ago, I can say this is the most detailed naming names deal I have seen. STICKY TIME.



Also, while propane is your cheap option it is has it's net merits in many ways also, so it can be said to be a step up in tech as well as a step down in price.


Just by the by, on torches, aircraft torches are designed for gas welding like TIG. The weight and flexibility is an issue there. There seems to be a lot of faffing around with torches and brazing. Speaking of weight lifting, look at the jig here, at 5:00 https://www.youtube.com/watch?v=ALNsQpCL8LY

It seems ok with propane to use the red regulators they sell for weed burners and BBQ set-ups, I just grabbed the first one I saw, and it has since worked fine. They sell for as little as 10 bucks. It might be a good idea to get a two stage, but then depending on how far you take it, you may not be adjusting the pressure that much. You want something for real, for oxy as it is under very high pressure. It is probably better to spend the money on a concentrator. The lamp glass guys are tapping the home heating for their set-ups. altogether a little scary, but no high pressure, and no transportation.
