dvm,

Nice symmetry with your floor layout.

A grinder will fix most of the scallops, your discovery will help others in the future for arched lintels. I used 1/2" OSB (sides) with 2X3 blocking and 5/15" ply (arch) in my arch form and had no issues with deforming.

Good luck with the rest of your build.

You arch looks great. I will make an arch over the adjacent fireplace; so I have another chance at this. The 8" metal flashing was very easy to use..... I think I will place the supporting boards side by side and cover with moist sand before rolling out the metal flashing. We will see how that works next time.

It was a great morning - I have to say standing up and finishing concrete in the shade with a nice breeze was a treat.

As I wait for this morning's cement pour to cure - I turned may attention to the oven archway.
I started with OSB template of the oven floor raise up on a few bricks. This allowed me to "dry set" the bricks for marking in prep for a day of cutting tomorrow. The carbide tipped brick marking tool from HD worked like a champ and won't wash off in the saw as would pencil - and the lines are sharper than a "Sharpie"
BTY the stick of wood on a hinge (when drilled at 21 inch radius first served as the compass to create the template) happens to be 2.5 inches wide which served me well when marking in the intersection of the soldier course with the arch bricks

Hey DVM,

I like the carbide tip brick tool. Tried clay and wax lumber crayons, wash off. Went to a sharpie, 1/8" wide so kind of fat. Going to head to the orange box store and score one of these so I have when finer cuts are needed. Thanks, love this forum. Good luck with the arch, I am working on mine right now and the taper angles are time consuming since my bricks are 5.25" wide that the trusty of HF saw on has depth capacity of 3" max. so four cuts per arch brick plus a grinding with a diamond cup.

As the hearth slab cures (and I am waiting for a 2'x3" FB ceramic fiber insulation board in the mail - 3 were initially packed 4 are required) I continue to cut and dry stack bricks for the oven archway and the lower courses of the tapered vent. I am working from a full scale pencil drawing on brown paper.

Here is a question for the community: I plan to use a tall soldier course with the floor set inside the soldiers (the floor is inside the dome, the dome does NOT sit on the floor). I will level the floor tiles with a mixture of refractory brick dust (from the saw tray) and sand spread with a notched trowel.
Question: Should I mortar the soldiers to the ceramic board, or simply stand them up and mortar them together?

DVM,

I had a similar question and I received an overwhelming "no" to mortaring to the insulating board (I used CaSi). I also cut the floor to sit inside my "sailers vs soldiers" putting a ring of cardboard between the floor brick and in your case the soldiers for expansion of the floor purposes and to keep mortar from dropping down in the gap and possibly cracking the soldier ring. Others have used this technique and supposedly the cardboard burns out and eventually fills with ash from the fire. Hope this helps.

I suspected as much. It is hard to picture but important to remember these these structures do not sit still - they with expand (move) and contract (move) as they heat and cool; with different elements moving different degrees based of different heat content. Makes sense to let it "float" and allow it to move where it wants. a cardboard gap sounds like a simple interface solution. cool. I mean hot.
