I'm Peter Reinhart! Ask Me Anything! Monday, February 15, 2016 7:00-8:00 pm EST

To kick off our AMA feature, we have invited author, chef and master bread maker and host of Pizza Quest, Peter Reinhart, to be our first host! Peter will be in the Forum on Monday, February 15th, from 7:00 - 8:00 pm EST. If you are unable to be online during the live session, you can post your questions in the sticky post. Peter will answer those questions during the live session on February 15th. You can view Peter's answers to your questions as well as what happened during the live session in the session thread.

Ask Me Anything New Forum Feature

You will notice a new forum at the top of the main page called, "Ask Me Anything". This forum will be used for live one hour "Ask Me Anything" (AMA) sessions hosted by people who are knowledgeable in different areas pertaining to wood fired ovens. How it works:
- Each AMA will have a "sticky" thread where the community can post questions they would like answered during the live session. This will allow everyone to participate even if you can't be online for the live session. These questions will not be answered by the host until the live AMA; if you need an answer quickly, you should post it in the appropriate Forum area for the community to respond.
- Another thread will be posted for the live AMA. Registered users who are logged in during the live session can interact with the host by asking questions and receiving responses.
- The live thread will remain in the AMA forum to view after the session.

We hope you enjoy this new feature! Please let us know if there is a topic that you'd like to have as an AMA and we'll look for a host!

  • Hearth floor support

    Hi Guys,

    Well I may not have decided what I am doing for my oven construction yet but sounds like the pompeii is what I will have to do. (he says as he shakes in fear)

    I will ask my question it may sound like overkill but I dont like 1/2 doing things.

    Once I have done the construction for the hearth prior to laying the cement I was looking at using LYSAGHT BONDEK instead of the plywood or MDF that everyone seems to use. This is what is used to support concrete floors in office building from what I can gather.

    It seems to also have a fire rating not that the slab will be getting too hot with proper insulation.

    Is there any one that can see and issues with using this on the floor. Good Idea or Bad idea?

    I will take a pic of the are I am looking at using and will see comments on foundations recommendations.

    Thanks for now

    I don't see a problem with using this profile steel sheet as the base of your hearth concrete slab.
    I would cut away the lower profile carefully to allow the largest flat part of the profile to sit on top of your block walls. I would then support it to ensure that then weight of the 4' reinforced cement doesn't sag the sheet leaving a considerably thicker an heavier center. This support can be removed once the concrete has set, usually after the dome has been built.

    Prevention is better than cure, - do it right the first time!

    The more I learn, the more I realise how little I know

      I considered Bondek when I was pouring, would've used it if I had some laying around.
      Instead I used boring old corregated iron.
      Worked a treat.

        As Neil & Paul said as long as you support it till it sets I do not see a problem either.

        I used some left over colourbond sheeting as my form and I had no leakage underneath

          My parents used this stuff in their top concrete slab of their house and this stuff is fairly thick compared to corrugated iron. From what I have read it cam be used on large expanses of space without support. I will however be putting a centre pillar in my build as support for the floor. As I said I pretty much overdo things LOL.

          The underneath of my oven is not going to be as most as there is a brick gadren bead that will be running through the centre of the oven so my storage are will ba alot norrower so I may as well use the space I cant use for storage as a support for the slab.

          I know my dad will say to me why did you use Bondek its not like you are going to be stacking elephants on that slab.

          thanks guys for your comments

              I have been considering the same thing. And I found a scrap dealer up the road that actually has some pieces that would be big enough. I know of at least one other person here that has used that type of steel decking: http://www.fornobravo.com/forum/8/el...en-3714-4.html
