maybe longer chimney on side chamber? I yield to the esteemed experts

The pipes gong from the lower chamber to the cook chamber and side box need to be a lot bigger. They are not big enough to allow enough volume of heat into the two upper chambers. Maybe even remove the one to the smoke chamber, move it to one end, and add a second. One way or another you need to increase the allowable volume of heat and smoke to the cook chambers. Go ahead....ask me how I know this

Do you think a bigger chimney would do anything because I can’t just pick it up and take it back to the shop it weighs 800 lbs lol . I just need 50 more degrees for my top and a 100 for the side

I would try extending chimney first, maybe just put a piece of scrap piece duct or pipe light a fire just to see if it works if not robert got ya covered he knows his stuff.

These are 3 inches you think 5 would be big enough round

Firebox to main cook chamber needs to be 10” minimum. The same going to the side smoker. If it was mine I would attach the side smoker to the main cooker directly. The exhaust pipes on each need to be minimum 4”.

Any way you have access to a portable welder? If you can fabricate / cut the stuff you need at the shop and bring it home along with the welder you might be able to take care of things without having to move it.

He is absolutely correct. You'll need at least a 10 x 8 opening between the lower firebox and main cook chamber. Same with the side cooking chamber. Stack(s) need to be at least 4" in diameter for adequate draw from bottom to top and to eliminate the possibility of smoke stagnating in the cook chamber(s) and creating creosote.

Please take a look at this thread and take special note of the heat deflector I built on this. You may want to consider fabricating something to the same effect in the bottom of the cook chamber. If not you'll get a direct heat blast right up the middle of the cook chamber and torch everything there while any food on the sides won't cook. I could do a quick rudimentary sketch for you of what I have in mind if you think it'd help.

Cabinet Smoker Build: Take 2 (Long, Lotsa Pics, Good Info)

A few weeks ago I posted a cabinet smoker build I'd done and at the time, I was really happy with it, especially based on an extreme lack of metal fabricating experience. After running the smoker through the paces a few times I realized there were some major deficiencies. I was confident that...

I’ve got a piece of I beam for a heat deflecter
