Re: New guy from west jordan utah with first question.

Going by the sun, the oven will be facing South by just a tad East and it looks like the prevailing wind is West by North West, so you got that going for you.

Probably the most observant comment ever!

So I never got around to building my oven. I hope to get started as soon as i can in 2017.

How long on average does it take to build one?

[UtahBeehiver]

That is a tough question to answer. It depends on type of enclosure, final finish, skill set, etc. The core oven will take several months. I am located in SLC so give me shout if you need some local advice. I have help several builders over the years.

Hi Roland, I'm in South Jordan and can also give you some tips if you have any. I was able to build the core of my oven in about a month. That was spending a few hours almost daily. As Russell said though, It really depends on how detailed you want to be. Russell is by far the best resource around and we are lucky to have him so close. If you have any questions though... I'd be happy to help out as well.

Question regarding the insulated hearth. Does a perlite concrete mixed hearth have to be poured the same day as the structural rebared concrete that would be under it?

Next question, are there any ceramic insulation board suppliers in salt lake valley? Also the blanket material?

Im going to be building the base this week, most likely. And i am going back and forth on a perlite base or just buying/"using insulated board material.

[UtahBeehiver]

No, the p or v crete can be poured after the support hearth, Is there a reason you are using pcrete and ceramic fiber board combined, ie height, budget, etc? In post 10 of this thread I listed suppliers of various materials in SLC, EJ Bartells is now Distribution International, located about 3000 S 900 W

Sorry for any confusion, I am not planning on using p crete and fiber board combined. I am going back and forth, considering the best option for the insulated hearth. My reasoning i.e ,thought process, for using just the fiber board would be ease of build and less overall weight. Using p crete would be less costly, maybe? But im wondering if the p crete is a good enough insulator, or if using fiber board is just overall better in the long run.

I read the thread about what people would have done if they could change their build, and a lot of people stated "more fiber board under the cooking floor." I dont recall anyone saying that they wish they had not used p, or v crete.

So if i can pour the stuctural concrete without having to pour the p crete on the same day, i would have time to change my mind, or have more time to decide on the insulating layer, P crete vs fiber board.

Thanks for the reminder on the previous posts on material suppliers. I should have read back.

So far ive bought " medium duty" fire brick, according to interstate brick in west jordan. Cost...1.89$ each 2/1/2 by 4/1/2 by 9 inch.

They are made by mutual materials mica brick plant. I emailed mutual materials, asking for alumina content because interstate had no idea. Mutual materials said they contain 16 percent. That would be low duty. Not medium, right?

interstate said that was all they sell, and they are 1000 degree rated.

This site discusses WFO using 18% Alumina.

Read Appendix 2 of the FB Pompeii plans - Brick Primer..........and decide for yourself.

[Roland Deschain]

mutual emailed me stating that they are low duty rated to 2000 f.

Just got done building my base and filling every other core with concrete. Next step is pouring the structural concrete on top.

[Roland Deschain]

Finished the structural concrete top today. And it was perfect weather. Question? What is an ideal distance from the front of the structural concrete to the center of an oven? Mine will be a 40 inch oven, inside 20 inch radius.

New question on proper ceramic fiber board. Not knowing the properties of the stuff, is the right stuff a soft or a hard dense material?
I found some 1/2 inch stuff a distributor wants to sell me cheap, but when i looked at it, it was kindof soft and indented a bit when i pushed my hand on it. Is that normal or no? Also how does it hold up with water? If i bought it, I would stack it to 2-3 inches for thickness. I want to put the correct stuff down. And if the 1/2 inch stuff is not the right stuff i will keep shopping. My other question is regarding insulating firebrick. Does it work as well? Inch for inch, for insulating.

What does the specs say the compressive strength is. I use ThermoGold 12 which had a compressive strength of 100 PSI, FB's board is 0.5 Mpa (metric) or abt 73 PSI.
