Hi Mike,
Thanks for the reply!
The drawings are made of the same forge. the first picture is a cross cut of the propane tank.. the other drawing is the front and back of the same forge.
I will do a search for a better alternative on the refractory. What about the exhaust outlets?

Hi,
I have been reading and tried to get some pointers on how to build a propane tank gas forge and have now made a concept drawing. I would really appreciate some feedback on my idea before I start building it.
Some background: I have been forging for some years and already have a smaller two burner gas forge but I´m now planning to get into the larger production of pattern welded knives. I like to make large billets so I can get 2-4 knives out of it, hence I want a larger forge to speed up the process. I´m in possession of a 50# machine hammer so I can move a decent amount of steel and want the whole billet warmed up to welding temperature throughout the whole process.
I have a larger propane tank that I will retire and use for this project and the dimensions are on the drawings.
Living in Norway it is hard to get all the stuff mentioned on this forum, but I have ordered insulation wool, Kaowool Rigidizer and ITC 100 HT from Canada.
I have found one manufacturer of castable refractory here in Norway Rated for 2730 Fahrenheit / 1500 centigrade with the following composition:
Borgcrete 50:
AI2O3: 50%
SiO2: 38%
CaO: 7%
Fe2O3: 1,3%
I told the manufacturer what I intended to make, and he claimed that he would not be worried to use it as a liner and for the ribbon burner.
I plan to make a FARB as instructed on Wayne´s site. I can only get 80x80 mm ( 3.15x3.15”) square tubes and plan to make it 12” long. Will that be enough on the size of forge I have planed?
Any feedback would be greatly appreciated!

Thank you Frosty,
I was planning to form the ends by hand, but if the round shape don't add anything I will make them flat.
Regarding your answer to the refractory I'm a little confused, are you saying that you thing it will hold up?
I know that the kiln wash is not the best, but I could not find the ones you mentioned. Guess it will have to do until I need to redo it.
