Smoker firebox/CC positioning

[dtett]

First of all, this will be my first build and I think its rather ambitious but I'm up for the challenge.

Starting with a 30"x72" piece of pipe. Cutting 20" off to use as a cook chamber.


My question is will I regret positioning the FB to CC opening lower than the top of the FB?

I have the two pieces of pipe aligned to the others center so I wont have a 5ft tall smoker as this will be mounted on a trailer when I'm done.

Any help would be great.

Your fire basket and fire will have to be fairly short. Otherwise your fire will choke itself out if the smoke has to drop down to get out of the fb. I would think about making a square fire box according to the calculators and having the exit at the top. Mounting the fire box close to the axle will help with clearance when going over bumps and through dips.

It is necessary to mount the top of the firebox even with the opening to the cookchamber. Leaving headspace on the top of the firebox is not advised.

Run your numbers thru the calculator to make sure your 20 inch firebox is acceptable. It will also tell you the throat, gap and chiminey size in order to achieve a well running pit.

10-4. I guess I'll go back to the drawing board. This was more of a cost saving exercise so no big deal.


Dirtytires: The fire box will be 30" in diameter. I'm using the feldon calc but the drawing was just for demonstrative purposes and not to scale as far as the opening is concerned.

Look for "Throat Calculators"
