can somebody help me out with this? I am trying to figure out how big my fire box, vents, smoke stack, etc need to be. I do not understand excel very well and cant figure out how to get these measurements out of the ratio calculator. If someone could get this for me and maybe email it to me? i would be very appreciative. My smoker is 84" long x 32" wide.

Here is a non-Excel version: http://www.feldoncentral.com/bbqcalculator.html

Is the smoke chamber round or square/rectangle?

If round:

Firebox 22507.52 cu. in.

Chimney volume depends on what your firebox size is. 1100 cu in is about right if you hit the recommended firebox volume.

Air intake will be around 70 sq in

Play around with the calculator a bit and you will see how one component changes another.
