Square Tube Smoker Build Question

[mattwheaton]

Hi all. Ive got a 6' piece of 12 X 12 X 1/4' tube. This should be big enough for my needs.

How do I figure how much of an opening is required for smoke pass through from the fire box to the chamber? Also, Im thinking about an 18" fire box and 36" smoke chamber plus or minus a few inches.

Any input gap size and overall dimensions would be greatly appreciated.
