New Forno Bravo Forum Feature

Forno Bravo Forum Community,

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.

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.

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!

  • Oven Floor and Oven Opening questions

    after responses on prior questions floor will be on angle iron at 16" center sitting on block wall. Cement board with rebar and concrete, insulation will be 3" calsil block (36"x12"x3") and then my fire block slabs (24"x12"x3"). 36" dome oven is my design. QUESTION - does insulation factor of 3" calsil block seem sufficient and also have enough density to support distributed weight of oven without breaking down?

    Next - read many books looked at Formo's plans but still struggling with opening - does anyone have good pictures or plans for the opening and chimney?

    I often wish I'd read this before I started.
    View these threads and you'll find many pictures of how the arch is married to the dome, and how most guys mate up the outer arch and chimney

    Here's a pick of how I did the inner arch to dome marry up, then I put a stainless steel hood and a brick arch in front of that for carrying away the smoke.

        Re: Oven Floor and Oven Opening questions

        If you are struggling with the opening and chimney, I've put together a 7 sheet pdf (attached here) of my oven and how it was built.

        My oven was a 42" diameter and I did the slightly harder thing of:
        1. Having a deep landing (the area between the inner arch and outer arch)
        2. having my landing "flaired": its a couple inches wider in front than were the inner arch is and the door goes.
        3. I was very concerned about having excellent draft of the smoke, so i made my "flu-box" (that's the opening above the landing) quite large and therefore had to taper it down, or rather up, to meet the 8" steel vent pipe.

        I've never done brick work before but we all learn as we make it and we figure it out with the help of everyone on this forum and their pictures.

        Keep looking at everyone's pics and you should get a good "idea" how its done and what will happen. Good luck, and hope my pdf's of what I did help. My drawings here are not instructions of how to built it, but it's just descriptive of what I did, and worked.

        good luck, Dino

          Avkroth, don't be threatened by the planning it takes to master that dome/entrance transition. It was a challenge to all of us. Study the different builds in the gallery and the link in my signature and you will see some different ways to tackle each challenge as you come to it. HTH

          Dino, that is an awesome document you linked to! Have you started your own album(s) here on fornobravo? You can develop your album and illustrate your exceptional build, then put the album link in your signature. I think your build and supporting illustrations are a great help to those in the planning stage. Your sketchups were pivotal in my oven planning, thank you!

          If you are thinking about building a brick oven, my advice is Here.
          Our One Meter Pompeii Oven album is here.
          An album showing our Thermal Breaks is Here.

          I try to learn from my mistakes, and from yours when you give me a heads up.

            Thanks Lee,
            That's a good idea, I should organize my info better with album(s) and a link.

            And thank you for doing such good job organizing information on threads and posts on this forum. You've greatly helped out the entire WFO community here!
