Cutting an arc in fire bricks - Forno Bravo Forum: The Wood-Fired Oven Community



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!

  • Cutting an arc in fire bricks

    Hi all

    I am seriously thinking about this, and as winter is not that far off in New England, I am sure that I will have 100 stupid questions between now and spring when I can get started. I hope that you are a patient group.

    My first question is if you intend to use insulating board below the cooking surface fire bricks and place the dome on the outside of the cooking bricks but on top of the insulating board, how are you cutting the arc in the firebricks so as to get a nice tight fit with the first course? My intentions would be to have the outside of the first course end up flush with the the butt end of the underlying insulation board so it too would have to be cut in a circle (plus the opening) requiring arc cuts.

    Most tile saws I have seen do a good job cutting straight lines, but how do you cut a smooth arc? Are you using some other tool?

    Thanks in advance.

    You use multiple cuts to approximate the curve. Remember: your soldier course bricks have straight lines, it's not a real curve anyway.

      A 4.5" angle grinder with a diamond blade is very useful for shaving off bits and pieces off bricks as you go.

        Approximate with the straight cut and fine tune with a grinder. Thanks.

        In hindsight my post probably belonged in the getting started catagory and that is where I shall head.
