After work I came home and started cleaning the mystery pit.
Took all the grates out, shoveled the large bits and vacuumed the rest.
Then I took a ball of aluminum foil and scrubbed every bit of the inside.
Sprayed with olive oil and dumped in half a chimney of Cowboy charcoal with one hickory split, halved.
I had some yellow potatoes going bad so I leveled the bottom and put my temp probes in them. One left of middle (probe 1) and the other 8in from the stack (probe 2).
While cleaning I did narrow the identity of this smoker. The original stack was on the back. It had been removed and patched. Whoever moved it did a good job of hiding it, on the exterior at least.
Fairly certain it is a early 2000's Brinkmann
30min into the first firing.
The splits caught, temporarily spiked my temp and is now leveling out to ~260 probe 1, ~250 probe 2.
approaching 2hrs in and I am already learning. I've been changing one variable at a time while adding wood.
Adding 2 small splits spiked my temps over 300, then dropped out - burned too hot and fast.
I put 1 small split in and it held temp, but did not last long before burning away.
I then added one larger log. It had some squiggly bits hanging off which of course caught quick and made dirty smoke. It took longer to raise my temp back up to goal, but held a little longer. But if I'm to use larger sizes I will need to add them sooner.
