Firebox too big

Postby bhfontenot » Sun Mar 08, 2020 11:34 am

I have a home built (not by me) offset smoker and going by Feldons calculator the firebox appears to be 140%, is there a way to get this number down without having the firebox remade, or is it needed? Maybe adding bricks to the bottom? Here are all the dimensions for the smoker if it will help-

cc- cylinder 30" diameter x 38.5" length
fb- cylinder- 25" diameter x 26" length ( 25" is the diameter of the pipe side to side, but top to bottom is 23.5" because the top is flattened, didn't know how to account for that)
chimney- 6" round
fb air inlet round- 8" diameter ( actual openings look like a radiation symbol so only around half is open at most)
fb-cc opening- half moon 16"x6"

Put some bricks in the firebox to displace to extra volume.

How does the cooker run? I have seen a many cookers with way over sized fireboxes perform perfectly.
if you could tell us the issues you are having we may be able to help you create a work around that does not invlove extensive mods.
Always remember slow and steady wins the race.
