Well Gerry, I never came across any recommended dimensions. I reasoned it needed to be larger than 8" so I went 10" wide . The nine tall was the height of my firebrick. I kind of figure that if its badly wrong then Peter or Max (or maybe Gerry) would let me know. :)
I have an option to use 10" heavy wall galv. pipe as my chimney, I haven't made up my mind yet, if I'll use it or 8" but I wanted to be sure my hole in the wall was big enough. I did consider putting a wall inside the bell so the hot gases coming down from the drum don't try to sneak out the chimney without first depositing their heat up top.
Capping has been on my mind quite a bit lately. I hadn't even considered a temporary roof ... what an outstanding idea!!! Hats off to you Sir !
My real plan is rather ambitious, and may change as I progress.
The small area behind the barrel will get a flat roof, I haven't determined at what height or of what material yet.
For the rest of the roof... I REALLY want to build an arched brick dome ... Like the batch box, Kirk built with the casserole door. I'll probably muck it up but... I just got to try.
I'm having great fun being an apprentice brick layer!
Now that outstanding idea of a temp roof... I want to run off to Sandpoint rite now and get a couple of sheets of hardy board! I could Fire it off early !!! Whoo Hoo ! Like you say, see if it needs a second bell !! Get it drying out while I prepare my form for the arch! I could sort of pick better weather before I open it back up ! WOW I owe you a beer my friend!

Made a big change today after talking to Peter over at Donkeys.
He suggested that a column would be a better choice than the wall.
I quickly removed my dry stack wall and replaced it with a mortared column.

Still making custom cuts to come up along the side of the barrel. Using Super wool as an expansion joint to hopefully keep it sealed...
