Well, I made some changes finally. Life got busy and this was put on the back burner.
@Frosty, sorry for replying the way that I was. Every forum I am involved in has different rules and that is one I will remember here.
I want a 2 burner forge because I don't want to be AS limited as I would be with a single burner. I want to forge weld eventually and I think I will be working with larger pieces in the future when I get that far. @VaughnT you're right, I don't want to focus on one thing (knives), I want to learn how to do everything from knives to scrolling to architectural pieces. I scrapped the side door idea for now. If I get the urge, or need, for something like that in the future, I'll figure something out. But for getting started, I don't need it. It wasn't going to be a wide open wall, as mentioned earlier in the thread, I just wasn't finished with my initial design when I made the rendering.
I have attached a (very rough draft) PDF of a 2D drawing of what I changed the size to. Frosty, you mentioned that those burners heat ~350 cubic inches each. This revision has 729 cubic inches. How far apart should I place the two burners? I've heard 7" O.C. apart from each other, but this design doesn't allow that amount of spacing. It has 2" of kaowool insulation around the perimeter and 3 K-28 bricks.

I just realized I had a brain fart in the previous post. Of course there’s room for two burners on this. I was thinking I needed 14 inches for the burners lol. Disregard that burner placement question.
