The guy running the pit at a gas station in Lockhart let me peek at his firebox
Stopped at a station off Highway 183 in Lockhart last Saturday and noticed a trailer smoker out back with a guy tending it at 7am. I asked how he kept his coal bed so even and he pulled the door open and showed me he splits his wood down to wrist-size pieces instead of fist-size. How small do you all split yours when you're chasing a steady 250?
Wrist size is the right call but nobody talks about the moisture part. Splits that small dry out way faster, and dry wood catches quick and burns hot without smoking. Wet wood chunked big will smolder and give you that dirty smoke. The guy in Lockhart is probably splitting small for both reasons, not just the coal bed. Small dry pieces let you add a little at a time and keep the temp flat instead of dumping a big log and waiting for it to catch. That steady 250 is really about feeding small amounts often, not splitting tiny for the heck of it.
