Put it together yesterday evening and did a first burn this evening. I've bought some stuff in the mod threads but haven't implemented many of the just yet.
What I did was flip the main chamber grate upside down and slid it against the SFB wall, used a flat piece of thin metal (Lowe's, 4"x12") and laid it over the grate and propped against the SFB wall to further baffle the heat. I also did the stack extension, I clamped the duct to the stack and then just let it fall out and was actually on the grate near the front of the chamber. Sprayed the grill down inside and out with veggy oil (Pam), let it cook and wiped off the outside.
Threw in a cheap oven thermometer (that I didn't try cal'ing since it was non adjustable) on the far left near the duct. I did check the stock therm in boiling water and it was adjustable (at least I think so, it had a bolt that changed the reading when turned) so I knew it was pretty close. Since neither are quality pieces I was more focused on the relationship between the 2.
Fired it up and took some readings (actually pics) and this is how it came out. The internal reading is the oven therm on the grate. Stack was full open and the SFB vent was slightly open after coming up in temps (see pic). Around the 1hr mark I added about 15 Stubbs briqs and another 15 around the 2hr mark (I unfortunately was so attentive on the start up amount but would guess 15 hot poured on top of 10-12 cold briqs and 3 small pieces of lump I had laying around).

Thing was beat up out of the box and that doesn't help it any...leaks pretty bad (I have some hi temp sealant and fire rope to work on that).
SFB vent
This is what we are looking for right.....TBS? Threw in some hickory chunks
I was a bit surprised at how steady the temps were given the gaps and holes that existed.
Next step, a couple of chickens....or maybe chicken quarters so I'm not waiting around too long.
