Coal forge beats my propane setup for knife steel, and I am done pretending otherwise
I ran both for a year on the same 1084 blanks and the coal forge gave me way better heat control on the quench. My propane burner from Centaur Forge gets hot fast but I kept overshooting and losing grain growth, while the coal let me watch the color and pull it at the right moment. Last Saturday in my garage in Akron I finally got a hamon line I actually liked, first try with coal after six fails on gas. Anyone else made the switch back, or am I just bad at tuning a burner?

That overshoot problem on propane is real, and it's usually the burner not the operator. A lot of those Centaur builds run rich at low pressure, so you get a big rolling flame that heats the whole chamber at once and you can't dial it back. I ran a 0000 tip in a Frosty T burner and still fought it until I choked the air down and dropped to 3 or 4 psi for the soak, then it was fine. Your coal forge gives you that instant read on color and decalescence, which is why the hamon came out clean on 1084.
