This morning I moved the nozzle up into the flare another inch. It is 2" form the flare opening, wind had died down also. I fired it up and it worked perfectly. I forged for 2 hours until I ran out of gas. It seems very efficient. I was able to get the 5/8 stock to forging temp with my gas pressure dropping to 2.5 psi. First time using a gas forge. I really like being able to see the steel color. Coal heated well, but it was a guessing game on metal color unless you pulled it out. Forge should be able to get metal to welding temp easily. I have learned so much form this forum and look forward to hopefully contributing once I get more experience with using gas. Thanks everyone!

Okay. The ss nozzle is 1" from the chamber.

I have the nozzle just up inside the refractory. Should be 3.5-4".

Pics of my completed forge. Still tuning but it is easily getting 1/2 stock to forging temps pretty quickly at 7 psi. The burner is chattering and I have tried different length .35 tips. There is a slight breeze which may be the problem, I am not sure. Volume is ~135 in3. Changing tip length does not help nor hurt the chattering which makes me think the wind is the culprit. I turned the T vertical because the wind, it seemed to help. I have the back opening blocked with a brick all except for the top 1/2". I used another brick to block half the front opening.

Finished insulation and refractory. Happy with it so far. Still waiting on the correct T for the burner. I think I have everything else. Thanks for all suggestions and comments. Again awesome wealth of experience in this forum.

I was unable to find the tees anywhere in town I ordered some from ebay. Hope they arrive soon.

Okay. I finished cutting my tank. I picked up some inswool and Resco AA-22A (Refractory) from a local source. I lined it with ~4" of insulation and 1/4 - 1/2 refrac. I am working on the burner at the moment. Like others, I had trouble finding the 1" - 3/4" T and purchased a 1" T . I bought a bushing to reduce to 3/4 from the 1". I purchased a ss nozzle from ebay that fits nicely on the 3/4 pipe. Do I need to cut the threads of the end and clean up before attaching the nozzle?

I will do that. I live in rural Northern Ky. north of Lex. Thanks

Sprinkle coal dust on your chisel.

Okay. After further research, I was beginning to think 2 3/4" may be the way to go.Glad you cleared that up. I have heard good things about the book and will definitely look it up. Thanks!

Great tips! I have been scouring information from this forum all evening. Sounds like you are the burner SME. With my plans, do you suggest 1" pipe rather than 3/4"? Also do you think one burner will suffice? I seldom forge weld.

Thanks Frosty! Yes I have been going over the T burner design. Looks pretty straight forward. Should the burner nozzle be at a tangent or 90 degrees from the work surface? I noticed in the design it was straight down. Being I will have a circular forge, what would work better?

Hi all. I have been reading this forum for a few weeks, what a wealth of information. I am a tinkerer blacksmith and have been using a coal fired forge that I made. It does well, but I have trouble finding coal and I do not like the fumes. I am attempting to build a forge from a 20# propane tank. I will be insulating with 2'' inswool and coating with 1/4 - 1/2'' refractory. I am stuck on deciding on a burner. I would not mind building one or buying a quality built burner. I am having trouble finding a decent burner. There is one for sale on ebay from Tacoma that looks decent. What do you all suggest for this set up?
