somebody shut me the fark up.
I knew it!I like to pile coals on the side Sometimes using bricks as a divider. I just add coals if the they run low. I use a folded piece of aluminum as a heat diffuser. I put a water bowl under the food to lower temp some, over the fire to lower it more. Don't be afraid to choke the top vent halfway if the temp drifts.
The ring sound interesting. I've never done it because what I do gas anyways worked for me. I may try it.
