sorry it looks like perhaps I misunderstood your measurements....

Not sure what you mean by vent landing? You mean the flat bit that the SS chimney vent plate sits on? If your opening is 41 sq in and you are doing your best to taper into the 7" diameter hole then I think you will be good.

By vent landing I'm referring to the flat area directly under your chimeny between your inner and outer arch. Yes I'm doing my best but we'll see

Ok that's what I thought! Yes, mine is 5" deep so less than a brick length from front to back! Which means I will be able to use full bricks to frame the flat chimney support.

Yours sounds fine to me. Why are the experienced people not weighing in? Do they enjoy watching the newbies trade theories?

Oh well, next year you and I will be the smart ones!

It all looks good to me except for the thickness of your bottom courses. I predict that you will not achieve burn off there, and also predict that it will make absolutely no difference in the performance of your oven. Looking great!

I don't know. Either way I'm sure we're going to love our ovens.

Ok instead of hijacking boerwarrior's thread I'll sort of repost my question here:

The issue of placing a parging layer around the entire outside of the oven dome has come up. cobblerdave has strongly recommended this step. What do you all think? I've been following the FB plans and this wasn't in there. Does it go on before or after the curing fires, do i need to let the parging layer cure for two weeks before curing fires...

I'm thinking of using one of the following:

Premix Conproco Type "S"
Dragon Type "S"
Conproco Type "S"
Structural Skin by Conproco
or
NOXCRETE (only one that I can use metal fibers in if you guys think that needs to be done as well)

Anyone use these?

I called Conproco and they said that I shouldn't use their product if the temp gets over 500 degrees. So that's out right?? Dragon said no also. The NOXCRETE would work but I'ld have to form around the dome to use it and my slab can't handle the increase in size to be able to add my studs and concrete board for my veneer. ughhhhh..... What about vermicrete would that work....

Local mason told me that the Conproco should hold up to the secondary heat outside the oven. Maybe the Conproco Rep I spoke with was thinking of direct flame contact....

I think a shallow entry is a great idea, it makes the oven much easier to work, but is not that easy to do with bricks, it is much easier if you cast the whole entry. You do need to make sure that the oven is adequately flued if you make the entry shallow, because the smoke is closer to the external arch.
