Just North of Nashville 42" Build

Let's see if this works!

Here is the tool without the angle iron attached. I will weld the socket and angle together but for those without a welder epoxy would work fine, something like JB weld would do the trick.

I'll post this soon in a new thread for this build when I get fully started. Right now trying to find materials, not having much luck with calsil board. If anyone knows where you can buy calsil board in the Dallas Fort Worth area please let me know.

Well so much for a lunch, figures just when you think you will have an easy day everything decides to break and of course needs to be fixed right now.

Back to the matter at hand;
That is an interesting IT design, the are a few things to keep in mind, seeing it is set up as a fixed length IT 38-3/8" horizontally it is not what it will be when you start going up at an arch toward the apex of your dome. When your IT is completely vertical it will be taller because of the OSB, socket and Swivel. The height added will be what ever the distance is from your floor to the point of pivot Which will result in a dome that is not a true Hemisphere. This is the reason most go with an adjustable IT, this way as you go up you can turn in the IT to get as close to a perfect hemisphere as possible. Mine is 42" and I ended up at approx. 21-1/8" tall inside. Here is a pic of the IT I used; very similar to many others only real difference was how I attached it to the floor.

As for the arch bricks, the size of them will depend on where your arch supports are in relationship to your dome (IE further forward or backward) I placed mine so when the dome came around I would still have about an 1-1/2" sticking out so I could notch the inner vent arch bricks and have a space for the heat break. (Pics Attached)

Hope this helps

I cannot take credit for this and I could not find the thread I got it from on here but it is the style I used and it worked great. I know someone on here knows you originally posted this.

The only thing I did not use is the clamp feature, I found I did not need it.

Re: Just North of Nashville 42" Build

Thanks for your help, my dome will be not quite 1" high so I'm not too concerned with extra height, looking through the forum here I've found many questions about a slightly higher dome and I haven't seen anyone that has claimed it made much difference in performance of the oven, if that's not the case or it would create a problem it's an easy fix. Simply shim the angle using different thickness, probably would only be a few but overall slightly higher likely not a problem. If that's not correct someone please let me know.

I the big scheme of things I don't know how much of a difference it makes, probably not much. Only the pizza can answer that.

Curious what you used for mortar? Also curious anyone's thoughts on using a pail premix that is air cured refractory? That's what my local brick supply carries and wondering the pro's and or con's?

Thanks!

Re: Just North of Nashville 42" Build

I used the FB mortar for the simple fact no one around here had any refractory mortar in stock and it was the same price. A lot of folks on here use the home brew mortar with good results and it is less expensive.

Thanks much! I'm curious about the pail mix that Acme Brick carries, mostly for the convenience. A friend of mine is in the boiler business (owner) and they naturally use all of the same products as an oven would use; actually he has a lot of scrap ceramic blanket in his yard that I can have and piece together if I want. Anyway they use an air cure premix and unless viscosity is a problem I'm not sure why it wouldn't be a good choice for oven construction.

Did you use refractory mortar in your flue? I am also contemplating simply using brick for my flue/chimney, which is going to be about 9' to get out of the building alone. Pipe is not out of the question but I have a lot of brick. However I have never built a fireplace/chimney so not sure if clay flue is necessary or simply use brick and basic mortar?

Not sure about the pre mix as I have never used it. For most of the bricks outside the dome except for the arch bricks I used a product from FireRock called adhesive mortar. It was reasonably priced and meant I did not have to buy more FB mortar

Re: Just North of Nashville 42" Build

Just a quick update as I actually had time today to do it. Have been working on the brick work as time and weather permits after work. If all goes well should have a decent chunk of it done this weekend.

Re: Just North of Nashville 42" Build

For rand18m;
In regards to your question about the air set mortar, I have read online that some air set refractory mortars are water soluble. If you Google "is airset mortar water soluble" you'll see what I mean.

What an amazing job on the oven, it needs bumped so I don't lose it! Can you go into a little more detail into your Firerock mortar, did it have a specific curing temperature, I can't find anything specific about it, have you cooked in this yet?

Thank you for the compliments.
The fire rock mortar is from this company here FireRock Building Materials - Provider of authentic building products for a timeless home.

It is not a refractory mortar and does not require heat for curing.
It is only meant to be used where joints are 1/16" to 1/8" and it is very different to work with as compared to the FB mortar that I used on everything else.

As for cooking in it we have used it 2 -3 times a weeks since it was done. I am probably at about 25 - 30 pizzas so far, several chickens, 3 -4 quiches, a turkey, and one loaf of bread.

I am trying real hard to get all the brick work done on the enclosure for a big party the Saturday after Thanksgiving. There should be 20 -25 people if not more so it should be 25 pizza night seeing the one we do right now are approx. 12" ones.

I still have no smoke stains on the outer deco arch and no new cracks other than the ones that happened after the first few big fires.

Re: Just North of Nashville 42" Build

Well here is a quick update,

Been cooking like crazy in it and love it.
The weather has been a real pain in my arse, the only awesome weather weekend we have had in a while was of course the weekend we had a camping trip so no brick work on that weekend, but the hiking was awesome with all the fall colors.

This past weekend was so damn cold at night and the mornings we had freezes so no brick work this past weekend but I was able to get all the power run to the island, the outlets installed and wired so as soon as the brick work is done on the front I can hang the lanterns.

This weekend hopefully will stay above freezing and I can get a good portion of the brick work done. Then I just need to re-pour the new landing area, install some black granite and I am done with the enclosure. After that I am going to start working on my full extension pull out wood storage that is going under the oven. It will be made out of an old fork lift mast and rollers.

Re: Just North of Nashville 42" Build

How did the project finish up? We are plannimg to start ad early in the spring as we can. I . would like to now but there are other unfunished projects to complete.

How is the granite entry holding up?

Why did you choose firebrick for the outer arch? DW wants to use brick that matches our house there....I wonder how it will hold up.

Hey ScottnDawna sorry for the late reply,

No the project is not complete mainly due to the weather. It has been too cold at night to do the last of the brick work and if it turns out that it is not going to be freezing then it's raining. I have about 90% of the brick work done on the enclosure and still have the front landing to finish. I doubt I will finish it up until the spring as I also have some concrete work to do. I will concentrate on building the full extention slide out wood storage bin and the doors for the rest of the kitchen.

The granite is holding up great.

The outer arch is not firebrick, it is a normal house brick just the rest of the bricks on the enclosure just a different style. I used it on all the corners and the outer arch.

I will have to post an updated picture of the front with the lanterns on and the bricks acid washed.
I will do that tomorrow evening.
