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!

  • fireplace and oven on top

    Hi all,
    need help to double check before construction begins

    right then,
    As part of a design for a garden, a fireplace was planned, so 8inch agg put down and 8inch concrete put down (no rebar) to support the brick structure which was going to be about 4foot tall tapering to a pot on top as chimney, the fire place, about 30in wide by 60in high approx.

    The concrete has been down for a month.

    last 7 days the owner asked for a pizza oven aswell in the same space, so steep learning curve begun.

    It was mentioned that it's not a great idea to have an oven on top of a fireplace, from what I've read here it has logic, but space and time are limiting factors.
    So it will have to.

    width and depth of the foundations also affect design, As the footings are approx 55in (140) wide x 30in (80cm) deep. Could the weight on the footings possibly be a problem? because of the extra weight?

    The pizza oven has to be half barrel shaped 18in high with door 15in
    (i think i will post this in another part of the forum aswell as this has its own problems).

    The question I need help with right now concerns the roof of the fireplace, ie directly above the flames.

    Because of height restrictions (ie don't want the oven too much over 3feet high) a flat ceiling for the fire was suggested, using reinforced concrete lintels and because of depth limits, the flue to be directed to the back and up as close to the wall that it's being built against as possible to allow as much space on top for the oven as possible.
    Can anyone see problems arising with the lintels?

    ok, think ive changed design a bit, going to have really shallow arches of engineering brick with ceramic blanket on top of them, then load bearing lintels, so no worries of loss of integrity, and spalling the lintels from fire exposure.
    Sounds better, doesnt it

      the second design seems to be a safer option, the foundations sound correct and there shouldn't be any problems with them however consulting a structural engineer might help you. also there is a software called SAP that can calculate if the foundations can carry all that load. this site might help you with some building tips (there are a few articles on the blog) armchair builder. I wish you luck with your project and hope to see pictures soon
