As far as arch shape, your choice, be sure to factor in mortar joint size in you CAD work.

Below are the current layout dimensions for the oven and the inner arch placement. As I've mentioned in the beginning, I'm building a brick chimney and more or less stealing .... I mean borrowing Joe's (Gulf) design on the vent arch(s). I played around today with the long reach and I see no issues.

Glad you mentioned getting the plywood out the door. I would like to think I wouldn't have forgotten that, but probably would have had the oven half built and realized It wasn't cut. Thanks. You are correct about the 2x4's. The arch is still about a 1/4" short of its final location. I will place shims between it and the 2x4 to get it dead on. In fact, I may end up rebuilding the arch. I've been playing around in CAD and I think I like an elliptical arch better. What do you think about the one shown below?
Oh, BTW, I started this build planning to build a 45" oven, but have reduced it to the more common 42" variety.

Couple items, be sure to split the internal plywood template so you can get it our the front door when the dome is done. Also save the inner arch form, it will become the template for your door. I think I see a 2x4 under the form, I am assuming this will be your release to remove the arch form once the arch is complete.

Thanks, Russell. Sometimes the engineer gets in the way of getting things accomplished. Got the plywood template cut and oriented on the hearth today. Also cut a template for the vent area just to get a feel of the width and depth. Built the form for the inner arch and set it on the templates to see how the opening will look. Expecting rain tomorrow, so probably won't get much accomplished other than assembling the brick support for the IT.

Looks like you are ready to go. Can see the engineer in you. Looking forward to seeing you do the build.

Finally back working on the WFO. Made a trip to Lithonia (Atlanta), Ga today to get enough brick to get the oven and vent built. I bought my supplies from Larkin Refractory. Great folks. Very knowledgeable and gladly answered every question I threw at them. I will be using 12" x 12" x 3" high duty tiles for the floor and standard medium duty straights for the dome.
Here are the tiles.
I also got a few 3" straights to use to set the vent arch on so I could bring it up to the level of the dome floor.
I've also started working on my IT. I am using a caster frame, a turnbuckle, all thread, a few bolts, nuts and bearings and brick supports made from wood. I have assembled the floor end as shown below. My plan is to place the center of one of the tiles in the dead center of the oven floor and then remove it and replace it with a wooden "tile". The wooden replacement will only be 1 1/2" thick bringing the pivot point down almost even with the finished floor. I show a test piece in the photo below. The caster frame I am using is from a fixed caster, no swivel. I removed the caster, drilled a 5/16" hole in the center of the frame bottom, inserted a 5/16" bolt and secured it with a nut. I then placed a skate board bearing, which fits a 5/16" bolt perfectly, and follwed the bearing up with another nut and then another bearing and nut. I bored an appropriately sized hole for the bearing in a scrap piece of wood and inserted the caster frame.
The last picture shows how I attached the left handed thread end of the turnbuckle to the caster frame. I designed and 3D printed a teardrop shaped bushing that fit the opening in the end of the screw and attached with a 1/4" bolt. I haven't built the brick attachments for the other end yet. I will do that this weekend. I'll post a drawing with the current oven layout with dimensions later. I hope to get the layout completed tomorrow, weather permitting and maybe even get the insulation board down and cut along with the floor tiles. Ambitious I know but have to set lofty goals sometimes to get anywhere. Thanks for riding along. Its been a long slow journey but will get kicked in high gear now that all the materials are on site. More later.

Dave,
I forgot how nice the mosiac was on the front this oven was. Very nice craftsman work who ever did it. Was this one of your cast products?

I also went with a thicker than normal hearth slab. Mine is a little over 6" thick. I was looking for ways to bring the height up a little bit. So a inch or 2 here and there adds up. Looking good. I can't wait to see the rest of your build.

Been in your neighborhood twice in May, first to graduation at Auburn, second driving a Uhaul to Minnesota where the stepson got a job. So I have seen a lot of your area in the past month. Have the say there is something to Southern hospitality. Everyone I met was very friendly and polite, not like people here in Utah who won't say hello or boo to ya as you walk down the sidewalk. Good luck with the build the fun is starting, again, you wait until it is hot and humid.
PS another highly engineered build by an engineer, 8" hearth is a bomb/tornado shelter...........LOL.

Current progress. Notice we finally got smart and just made a simple phone call to get concrete. Much quicker and less tiring.
Pulled the side forms off today. Will remove the interior forms at some point. Not in a real hurry to do that right now. The hearth slab ended up being 86" x 98" x 8". There is a 12" overhang on the front. Hopefully the oven itself will progress somewhat quicker once I get started.

Wow, its hard to believe that it has been almost a year since my last update. I have progressed, though. All concrete and block have been placed. Poured the hearth slab this past Tuesday. Now the fun starts, building the oven.
Progress photos.
