What happens in this video
Stable temperature starts before the meat goes on. A large offset needs time for the steel, cook chamber, and airflow pattern to settle.
Mr. B demonstrates his Shirley Fabrication reverse-flow smoker without a water pan or aftermarket modification. The plate carries heat toward the far end before the flow returns toward the stack.
Dampers give him another control point, but the broader lesson works on any offset: use seasoned wood, establish a clean fire, preheat the pit, then make deliberate airflow changes instead of rapid corrections.
Mr. B’s Pitmaster NoteA thermometer reading is a snapshot. Watch the trend, learn the delay between an airflow change and the next reading, and judge the whole pit before you move the meat.
Food and fire safetyNever assume an insulated firebox or smoker exterior is safe to touch. Use heat-resistant gloves, keep children and guests outside the hot zone, and maintain clear space around the pit.
