....would like to avoid some of the mistakes I made on the first one.
Have never been real thrilled with the, what I think are odd, temperature fluctuations. End to end it only varies 10-15*....going by the calibrated cc thermometers. But....the grate temperature, in the middle of the cc, is 50* hotter than the thermometer that is in line with this area.
Try to clarify this. Clamped a Thermoworks probe onto the middle of the cooking grate, directly in front of a thermometer. The thermometer read 260*, the grate read 285*. Placed 2 bricks on the grate. Between the 2 was another Thermoworks probe, on top was a third Thermoworks probe. All 3 probes were directly over each other, all in line,with the thermometer in the body of the smoker. The body thermometer read 260*, grate level Thermoworks read 285*, Thermoworks probe between the bricks read 310*, Thermoworks probe on top of the bricks read 335*. All probes and thermometers were checked for calibration the morning I performed this experiment. Bricks were in the smoker the entire time. Temperature never spiked, so the bricks werected not any hotter than the chamber.
The exhaust is terminated j7st inside the cook chamber. Just as a guess I thought that perhaps dropping it to grate level MAY help. Had a piece of the chimney left. Rolled up some flashing material to fill the gap between the existing chimney and the extension. Placed a hunk of metal inside the smoker to hold them in place. Didn't change the variations.
Hmmm...
