Lee: the charcoal in a pan didn't upset the draft to the point it was difficult keeping the charcoal lit?
Firemonkey: I'm still 'resisting', despite advice from experience

, filling the fire pit every time. Last night I grilled perfect chicken legs on the top grill, with a clear space down to the fire pit which I only had 3/4 of a Webber chimney fill of charcoal in, which just covered the bottom of the pit. I kept the bottom of damper open and opened, for the periods lid was down, the top damper open to the extent you could see a couple millimetres of clear air under the screw. It kept a great high heat, coals red/white hot the whole time, and when I dampened right off I note I still have half the coals left this morning.
