I'm thinking so. It's one of the ones to choose from in the site.

Is that FB/CC opening going to be large enough for proper draft on a pit that size? :scratch:

The calculator said a 41.91 sq in opening. I used two triangle calculations @ 4.250" x 11.5" = 24.4 sq in, double that and I should have a 48.8 sq in area opening correct? Or did I miss something? If it needs to be bigger I can add an opening in the bottom joint of the cooking chamber and not raise the firebox, I will just have to add a deflection plate under my tuning plates. Please let me know if I misread the calculator.

Have a question, I am using a 4" exhaust stack and am thinking of using an old design that I had laying around. At one time I built a internal damper, never used it and now am asking if the flapper would affect the flow? The flapper is 3/16" plate opens fully. I myself don't think it will have to much of an affect but figured I'd ask you all.
Thanks

Pics are always so deceptive! Like watching something about underwater life on National Geographic; you see this sea creature that looks so small, THEN they tell you it's over 15 ft in length and weighs several hundred pounds.. Can't really tell the measurements based on the pic alone lol.

What are the cooking chamber and firebox dimensions?

You can use the internal damper although they aren't needed.
