WOW!!! I installed my tuning plates on my offset masonry smoker that I recently upgraded with a new top and doors.
Below a photo of the results! The two temps are from BBQ probes at each end of my smoker.
I fed the probes in through small holes I drilled into the rear of the CC.
Below is a photo of the inside of the upper part of my CC - you can kinda make out the two probes at either side of the CC protruding out of the rear wall.
Below is photo of my tuning plates. Initially I just guessed at what might be good positioning of the plates. But after watching the temp probes, initially the left side was consistently 20 degrees cooler than the right side. After tuning the plates, I seem to hav gotten the temps within two to four degrees F quite consistently.
I think I am tuned!
Below is photo of my old smoke/heat diverter. It was just a guess at what might help. My guess now is that it didn't work very well!
Below are two pics of my old smoke/heat diverter installed in my smoker. The inlet to the CC from the FB is on the left, just under the old smoke/heat diverter.
This tuning plate thing appears to be the kitty's tushy!
Thanks to all on this forum for sharing so much information. I had never even heard of tuning plates before I happened along this forum.
