I wasn't sure what to call this thing, so I guess I will call it a Pitmaster Double Deluxe Reverse Flow. Decided I needed more smoke chamber area so I sliced in half and adding 12" section. This way I can add an upper rack. According to the calculator, fire box is big enough, but chimney will need to be longer. Here are some pics of what I have gotten done this weekend. Thought I would have it mostly finished but neighbors car needed some work on Saturday, so I didn't get started till late afternoon. Putting a bend in reverse flow plate. The before pics. Sliced in half. Top half off. Adding in the 12" sections. Getting pieces lined up. What I cut it with. Crappy shot of reverse flow plate being test fit. Under reverse flow plate. Reverse flow plate after some 3lb hammer work on sides. Still need to get front piece cut and fit. Going to have drop down door. It is just tacked together for now. Don't want to weld solid till every piece fits perfect. Will try to get some work done on it this week after I get home from work each night.
