Epic Fail
When I fired her up I watched it for 2-3 hours. It stabilized around 200 and was holding. Smoke was good but had some leaks which I expected. However at about 4 hours the yellow pine started shrinking and warping, especially the door. The more the door warped the more air got in and the hotter it got. The roof also buckled. The main box is ok, still square. Some of the tongue and groove wood shrank but not badly. Already tore off the roof and will have to decide on wood replacement or a metal roof. Might be hard to find a non-galvanized roofing. Will also have to remake the door.
But on the positive I do have some chipotle ready to make seasoning out of.
I believe you never learn anything if you don't fail. Redesign, rebuild, try it again.
