Very new to forges and thank you for all the great info. Been taking notes on this thread and the burner.
I have a need to heat long pieces for treating. I am looking at a forge that is around 30-32" long running 3 or 4 burners.
I am looking for any input of design considerations for a long forge that may not have been already discussed.
Also, if I am right, the metal will take longer to heat at the ends in a forge. So how much longer, if any, should the forge be then your material? Need to bring the whole piece to critical temp.
Edit: Not sure i understand the disadvantage thick wall outer frame (Say pipe) over something thin like a tank.
