Re: 36" Pompeii in DC
After closing the dome on Wednesday, while my in-laws went out sight-seeing, I started working on my vent arch. This ended up being a bit more work than I expected, and I ended up having to finish it in the evening, and left s-curve for the chimney incomplete.
Thanksgiving morning, I took a few minutes to remove the forms, and clean up the mortar from the arches and the debris from around the oven. To my everlasting surprise, the arches stayed up!![Smile](https://community.fornobravo.com/core/images/smilies/smile.png)

Today, with the in-laws having gone home, I finished off the chimney base, such that it's ready for a flue to go on.

I must have mis-calculated somewhere, because instead of the opening being almost 10" across side-to-side at the top, it's only a bit over 5", giving me an opening slightly larger than 5"x6"

Still, since my oven opening is just over 200 square inches, a vent of just over 30 square inches comes to right around the 15% ratio that seems to be recommended. Given that I'm planning on putting a relatively tall flue on top of the thing (haven't figured out whether to go ceramic or stainless, round, square or what), I think/hope it will draw just fine.
If I'm wrong about that, someone let me know! I could still knock the top couple of bricks off and shave them down or something.
Cheers!
