I am going by years ago, in 2004. Once we had temp control we learned how to control the heat in his big forge/foundry, as we could make it so hot it could melt steel. Scared us.lol A little extra O2 goes a long ways. We had regulators for the propane and O2 and air compressor. He had built a forge more for blacksmithing than knife making. I was more into making knives than he was. Did some awesome blacksmith jobs with that forge and he's still using it.
