Chat with a farrier made me change how I set my forge's air intake
I was at the county fair in Salem last week, just watching the horseshoe contest, and got talking to one of the farriers. I mentioned my coal forge was running a bit dirty and he asked me a simple thing: 'How many inches is your tuyere pipe off the firepot floor?' I told him maybe four, which is what my old teacher showed me. He just shook his head and said, 'Try two and a half. You're pulling too much cold air under the fire, wasting fuel and making clinker.' I went home and adjusted it that night. The difference was huge. The fire got way hotter and cleaner, and I used less coal for the same heat. It's one of those tiny details you never think to question. Has anyone else messed with their tuyere height and seen a big change?
