Offset smoker - different temperatures [please help]

Postby tmaven » Mon Apr 17, 2017 5:40 am

Hello pitmasters!

I just built my custom smoker. As you can see in the gallery - https://goo.gl/photos/rwgCEvfQtVKchkJN7

Parameters (I'm in Czech Republic / Europe ... centimeters, sorry guys!)
Chamber - 120 x 59 (1 wall thickness)
Firebox - 50x50x50 (0.6 wall thickness)
Chimney - 9x9x100 (0.4 wall thickness)


I have 2 grade levels in 2 separate positions.
Thermomethers are in the middle of grades. They are accurate (tested side by side).

But I have problem:
I'm getting different temperatures on both sides. (0-20°C difference)
I have ceramic roof tile as heat shield inside. But it does not fix it.
I tried water pan as well, but no joy.

What can be the problem?

I checked few smoker calculators - looks like I have long chimney... Should I cut it? Will it help to fix temperature problem?

Thank you!

There is a guy on here that is pretty good with building and helping people out. Once he see's this he will most likely be able to help you.

While 68° left to right is not uncommon a smaller cooker you could probably trim that some with a few tweaks.
Can you please post pics of the inside without the grates? I would also like to see pics of the inside without the tiles.
You can post them here or my email.

Thank you kam - https://goo.gl/photos/wmvM1DuXGCvrrQUj8 (all pictures I currently have)

As you can see, there is already metal heat shield, but it was too small (i guess). So I put roof pile on it.
