I built my rf offset and I have a 5" lip at the top of my fb meetin up to the cook chamber, now I know this makes my fb side in the cc hotter, my question is can I weld a plate uptop inside the firebox to make the top smooth into the cc and get rid of the hotter side or is this not gona solve my problem?

Just put a water pan on the grate next to the firebox & the temps will even out. I use a welded s/s drywall mud pan in my Lang. Had to order it online, cause all HD has is crimped sides & they leak with just water in them. I also extended the stack down about 6” & that leveled out the top to bottom temps. Will see if I can find a pic. Here you go!


I just thought I would share what I have done to my Lang 36 Patio to get even temps across the entire cooking chamber, including not having the top rack running hotter than the bottom.
I simply put a bread pan full of water next to the fire box, & extended the stack down into the cc about 6 inches.

I also added a couple of more gauges and you can see that the entire cooker is running about the same temp!

When I first got it, the fire box end was about 20 degrees hotter than the other end & the top rack was about 20 degrees hotter than the bottom rack. But with a little tinkering it is even all the way thru. Very easy fix!!
After this photo the bread pan rusted thru, that’s when I bought the s/s mud pan.

It’s a reverse flow, so it’s a smooth flow from the firebox. The main thing is how does your smoker draw the smoke & heat. Mine will draw it with just a AMNPS in the firebox, no fire or heat.

embrace your hot end… I like having a hotspot. When I do a big cook I put my larger Boston butts on the hot side and smaller ones on the cool side and it works out quite well
