First smoker dimensions help

[rwitt1409]

Hi,
I’m having a friend weld me a smoker and was wondering about dimensions, particularly the chimney size. How does all of this look:

16”X36” cooking chamber
16”X12” firebox
40” chimney at 3” diameter
20” opening from firebox to cooking chamber
What do you all think?

Fire box might be a little small...but then again maybe not. I just know I've seen them considerably larger on some units. Can't tell you how big to make it, this just seems small.

Chimney should be 4" diameter minimum.

Best of luck and keep us posted. There are tons of links to smoker builds that you can find using the search option at the top right of the page.
