The initial assembly is complete. I used red high temp silicone to seal the fire box and the chimney.
I put a felt gasket on the lid.
That caused the hinge to be misaligned, which I expected. Here was the smoker at this stage of the build.
Then I took it to my local metal fab shop for further modifications. They are going to remove and re-align the hinges. Build a water box with 1/4" plate, install supports for tuning plates, make me five tuning plates from 1/2" steel, and build a charcoal box to sit inside the fire box.
