Thanks for the tips! Yes, I was actually planning to go with soldering torches, but to be able to use a 20 lb. tank seemed like an advantage... also my soldering torches are quite small. I think the BTU output of these burners is higher than that of the soldering torches I have, and they would be sufficient for my mini forge (at least for heat treating steel, my main objective), but somehow, the shape of the burner tube I crafted causes too rich a flame... I was trying to figure out how to make it "poorer", so I could have a device that is one step up (all be it a little step), from a soldering torch. The orifices are quite large, but I read somewhere that a BBQ pressure regulator outputs a very low pressure, so I guess in the end, the result is the same... So you say it's completely hopeless? If it had the same BTU output like a soldering torch or a little more, I would still be interested in getting the flame "trimmed". Theoretically at least, what is my problem?

Hi Frosty, Thanks for the reply and welcome! I was planning on making a sort of slightly elongated bean can forge, maybe 4 in inside diameter, and a foot long. Could you please elaborate on how I have closed the air intakes? Here's two more pictures... I didn't take the part with air intakes/burners, just up to the orifice (I believe that's what it's called?). The only thing I did was make and slide on those black pipes. Basically, I wanted to use the hose, pressure regulator, and gas fittings, as buying them individually from welding places would end up being pretty expensive, I imagine...

I am working of a double burner for my forge (yet to be built), and need some help with the design. I was breaking my head over where to start, when it occurred to me: why not use the burner system from an old barbecue? As you can see, the only modification I have done is to slide a metal tube over the orifices of the BBQ part, drilled in some air intake holes, and flared the end a very little bit. While it burns nicely, I think there is too much orange/yellow on the flame... i.e. inefficient combustion? What should I change to get a better flame? Thicker tube? Bigger flare? More air (I think that won't work as it already has so much air that the flame occasionally "moves" as much as an inch away from the end of the pipe...) ? Any tips/advice appreciated! John P.S. First picture is of minimum flame, second of maximum.

Hi all! Just wanted to introduce myself and say hi. I'm new to the forum, and new to blacksmithing; as a matter of fact I don't even have a forge yet. I'm working on that though, and am in the process of designing/building a propane forge. Anyone else in the Edmonton area that could help me source steels, tools, etc. locally? Thanks, and I look forward to learning a lot here... John
