Help with dimensions please

[Rino C]

I'm looking to build a pompeii oven but I have a restricted space to build it in. Unfortunately the largest internal diameter I can achieve with my space is 28". Using the dimensions in the ebook I tried to recalculate the required vault height, door height & door width for my internal diameter. I came up with the following:

Vault Height: 11.25"
Door Height: 7.25"
Door Width: 13.05"

Can anyone verify if these are correct and will work?

Also any reccomendations or advice would be greatly appreciated.

Thank you!

Hello Rino,

If you're willing to sacrifice a bit of thickness off the dome wall you can easily increase your inner diameter by at least 2". That's exactly what I did on my current build. My dome wall thickness is 3" around the base diameter but used 4.5" thickness once there was enough clearance after the 4th course level.

Following in on George's advice: if you're using a rectangular enclosure, you only have to trim the three edges of the dome where they approach walls. You don't need to put the metal studs there either: you can run a secondary sill above where the oven curves in.

"if you're using a rectangular enclosure, you only have to trim the three edges of the dome where they approach walls."

.. and you can use the FB blanket insulation at these locations. 2 inches of this = 4 inches of vermicrete.

Thank you for the input guys,

How much would the heat retention be affected by trimming down the walls? Would I be better off using a full brick with a thin layer of vermicrete and FB blanket?

I plan on doing a rectangular enclosure, I guess I should have mentioned that earlier.

Over the thin walled areas I'm using only blanket. I assume it's more efficient that way rather than using a little of both...

Rino Look at my build, I have 29 inch cooking surface and I have all my measurements in the build.... This oven heats up nice and stays hot
