Controlling Air Flow

Holes in the burner pan allow ample airflow into the smoker. To regulate the amount of air flowing through the smoker, I installed a couple of circular air dampers on the lid.

I ordered these from amazon.com and installation was simple. I drilled holes aligning with those in the damper, plus one in the center for the mounting bolt. The dampers came with mounting bolts, but I had to purchase longer bolts to pass through the thick wood of the barrel head. I also cut the resistance springs to shorter length so that I could use a shorter bolt.
