Every other core and you are golden. You said that your base base has mortared block. Is there steel coming through it from the slab?

No - That does concern me. I started out this base with the Allen Scott oven design and changed gears. The pad is thick and has rebar in it, but I did not have the mason drill any rebar into the pad. I figured I would fill the holes and put rebar and concrete in the holes and if for some strange reason anything decided to move off it's mortared base it would be one big mass.

I do not have frost line issues here or heaving problems with the ground. I guess I am farr enough south that most pad installs here are monolithic.

I concur - if you tie it together from here, how in the hell can the mass move separately? Do you have earthquakes in Alabama (other than when Bama loses )

Actually, we do have earthquakes! And once in a great while you can even feel them!

Bama never loses!

They just occasionally have point deficits at the end of a game...

"MK-101 for $363.00 with a blade on it also"

That is a good buy. These are well enough made that, after you build your oven, you can probably sell it for around what you paid for it.

OK playing around since it is raining so much. Maybe I can get some of the form today.. Maybe

Here is a Sketchup Drawing of my project.

Well I got started on framing the hearth today. Notice how wet everthing is !!! It's been raining for like a month straight!!! Got the inside of the base framed up. I also cut my plywood for the top of the frame. (Ripped 4x8x56 into two parts).

I used screws and installed all so they can be removed from the bottom to get the forms out.

I used 2x3 for leg supports. They were cheaper than the 2x4 and I feel I have good support under the slab.

I still have to build the cantilever frame and I am going to widen the top to accommodate a 42 inch oven.

3 questions (OK lots of questions )

I am looking at a 20 (Maybe 19 after reading) inch door that is 12 inches high in the center. My dome will be 21 inches and the 63% rule says my opening should be 13 3/4. Will a lower opening help or hurt? I read the Sticky thread on openings that James posted and I like the special door with the wide bottom for Pizzas and a buldge in the center for taller stuff like bread to go into the oven.

How large should the vent opening be? I am thinking as wide as the opening and 4.5 inches wide (Half of a brick). I want draw, but not to much as to suck out heat.

I am thinking of a flared opening that is basically a straight line out from the center point of my oven. I guess that is perpendicular to the radius of the dome. (Damn I should have studied harder in school) Back then the thought was I'd never need all this math... boys was I wrong...

Also my center point of my dome is in the middle of the base mass (in the photo its where the 2x4s cross in the middle). This is basically 36" from the back edge of the block and 32" from the side. Is this the correct center for the dome? I am figuring after the floor brick is laid in I have 15 inches from there to do my soldiers and insulate and frame (I am actually thinking of a mosaic or igloo look) . Is this 15 inches enough?

On the hearth front the cantiliver will add an additional 12 inches to that 15 so I will be 27" from the center point of the oven to the outer edge where I'll be feeding the oven. Anyone having issues with there oven and the reach inside?

All the reading (My wife thinks I am a FB junkie at the moment ) but I am reading out of fear of screwing up at the moment .

So off to get some rest..

Hey just bumping this thread to see if anyone can help me answer a few questions I have before I dive back into the Pompeii pool this weekend?

[MetalHead]

Well I made another trip to the Hardware Store to pick up some more wood for my forms. I spent another $64.00 and I'll see if I am going to need to go back again for form materials

I am thinking of getting the mixer that lowes sells. Has anyone used it?

I don't understand (not an unusual state of affairs for me). From what I can see all you need is the floor and the sides. A sheet of ply should do that, so how'd you end up paying $64?

(Note to self: probably not worth a trip to Columbiana for lumber...)
