Fortunately the wedges were all pretty much all the same with a minimal slope that made prefect little wall bricks when paired with matching wedges, and it gives the brick lines of the wall a wavey wonkey look I am very fond of. After 3 rows of these I spent more time trying to match the ends to make the "waves" consistent.
When I had finalized the chamber dimensions (mostly) and the design I spoke with Mr Ward at Ward Burners (invaluable resource) and checked my math on BTU/Hr input and am using 2 MR 100 burners with Baso safety and high pressure pilot and fired at 4.5 psi peak to hit cone 10. My chimney is 6 feet of brick going into Class A double wall stainless chimney pipe. The opening of the roof the pipe passes through is lined with 2inch 2300 degree cerablanket. I had cut it for the exit flue I was using when I had a fling with an old 10cuft Torchbearer updraft gas kiln. I did check the melting temp of stainless steel the morning of the first firing to be safe since the Class A pipe is rated only to 2000 degrees. I tried to make the base of the chimney have some thermal mass to take some energy out of the exhaust, but I suspect at peak temp for a cone 10 firing I am exceeding the rated temp by some couple of hundred degrees.
So Anyway, I made a light saber, now am I a Jedi?
