Learning generally boils down to "Repetition or the avoidance of pain", some people learn by doing, some by watching and some just have to pee on the electric fence.
Whether you think that you can, or that you can't, you are usually right. Henry Ford

I put the fire brick on the outside of the firebox. Made multiple cuts to try to keep contact with the metal. (Tried to attach pictures but got a system error.)
Skip the bricks. Not really necessary in my opinion. Seal it up, as you did, to help efficiently and then just cook with it. There are a million things you can do that “might” help a little but at the end of the day you are not going to make a Lang out of it.
Congrats on entering the smoking world. We look forward to seeing what you can cook with it.
