Re: Well here goes nothing

Utah yep I got 2x8 brasing under the durock. I'll put some in the middle of span also.
I'm going to use 2" FB. Gotta make some calls to track it
Down plus fire clay to set it with. Then lay out.. It turned out
A little narrow 63x 78 1/2... I'll make it work

Re: Well here goes nothing

I went with a 3 1/2" concrete pad with rebar, 2" vermiculite/port;and and then the 2" rigid FB insulation.

Top of the area where the wood is stored (bottom of the concrete pad the oven sits on) still gets about 15-20 degrees hotter than the walls.

Re: Well here goes nothing

What are you going to finish your enclosure, 63" for a 42" ID oven will work as long as the finish material is not too wide, ie brick. You can always bridge your enclosure framing at the dome tangents and gain a couple inches. Looking forward to watching your build.

Re: Well here goes nothing

I'm getting ready to buy concrete for top. Seems
I'll need about 22- 80lbs bags for 63"x78 1/2"x3 3/4" that's
1760 Lbs top!!! OMG that's heavy! If anybody thinks
That isn't crazy it is!! I'm going to beef up my bracing!
I'm also going to redo my rebar matt. Hope to pour
Monday, and start dome next week. Oh Utah I'll figure out how I'm
Going to finish it off when I get that far... I'm thinking
Stucco dome with nice brick arch and flue. In pa we get
A lot of snow and crazy weather. So I also plan on a
Craftsman style roof.

Re: Well here goes nothing

If I recall, I used 17 bags, plus the portland and vermiculite, and my pad was smaller than yours. Yeah, the weight really starts to add up.

Re: Well here goes nothing

Should I lay up a middle pier? 1760 lbs top
Plus the dome weight and heat??? I can't imagine
3 1/2" being enough to hold all that?
I also need some ideas on what brands types
Tile saws you use? Seems a FB would be a lot
To cut on a tile saw? Anybody using harbor freight?
Hate to drop a load on a saw for just the dome?

Re: Well here goes nothing



I think I'm ready to pour the top! Gotta pull
Off for a couple days. Hoping to get poured on
Monday. That will be last post in this section. I'll
Move over to Starting Dome.

Re: Well here goes nothing


Okay game on! Gotta read up on making fire clay to lay the FB, and floor bricks. Dome layout and for some reason I can't open that dome calculator on my iPad! Need to figure out dementions of cuts for corses of bricks

Re: Well here goes nothing

Looks good! If you cannot get the calculator to work, post or pm me the dimensions of your bricks, oven diameter and height of IT above floor and I'll generate a PDF that you can view on your iPad.

I would try opening dome calculator on a "PC" and not the iPad. The pads are good for alot of things but working with documents and spreadsheets is not one of them.

Re: Well here goes nothing

You guys are awesome! I would of never
Attempted this oven without this forum.
Soon as I get FB and bricks I'll get that info
Posted. Thanks again.

Re: Well here goes nothing

Unless the FB is really out of wack, a lot of times it does not require leveling. But if it does, a mix of 50/50 fire clay and sand will do, if you use a wet mix you need to coat the FB board with something to keep the board from immediately sucking all the water out. You can also use the mix dry, use a 1/4" notched trowel to put mixture (wet or dry) down on concrete.

Re: Well here goes nothing

Book, no FB anywhere?? I can get brick, fire

Re: Well here goes nothing

ANH carries Insblok 19 and have dist. centers in Pittsburgh and eastern PA. I used Thermo Gold 12 from EJ Bartells but they do not have any offices in the eastern US.

Re: Well here goes nothing

Score ANH has the INS Block 19 and it's half
The price of FB? I'm guessing it will have the heat
Value in need? Is it hard to cut? I plan on laying
Up the dome on the out side? So this and Fire brick
Are inside dome. Wait will having the dome sitting
On the concrete counter or shelf cause heat lose?
