So, I have decided to track my feeding and temperatures for the Shelburne via a spread sheet. I am roughly getting the same, on a good bed of coals, putting in roughly 4 splits, I get up to 500, or 550, then I shut down roughly 1/4, then another 1/2 or so 30mins later..I will let you know how long this burn will last. Do you add wood when it's just coals or when there are still lasting flames on the last dying load. I'm still playing around with air flow, experimenting for the best solution. I don't have a flue thermo yet. To keep the flue clean, how long should we be burning at 500* for? I wanted to let you know I find this tread very helpful, thank you! Oh, also, how forgiving it it when hitting the upper baffle, I know I have waked it a few times, because I am not use to it being there.
