Smoking in NZ

[grant finn]

Hi,
In the process of building a reverse flow smoker at the moment. Really enjoying learning how these work. I do have a few questions though, my tanks it's 21.25" id and 35" long. With a 15x15x20 firebox the calculator says I need a 36ci opening, but later on the calculator post it reccomends opening that up 50% larger again for a reverse flow smoker? Any help greatly appreciated. Thanks

Afraid I can't be of much help with building this but I do want to say welcome aboard from Wisconsin, USA :)

I'm not a builder, but the guys on here use this calculator.

If this is not the one you are using, then plug your numbers in here & see what you get.
