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!

  • Grinding high spots on oven floor

    Hi all,

    Anyone have a recommendation on what to use for grinding down high spots on oven floor? I have a 4" angle grinder, but the diamond blade grinder I have is too aggresive. Just have a couple bricks that are 1/16" higher than others and worry about peel chipping corners off later, want to take care of this before dome gets closed up. Thanks, pat

    You can buy 50 grit diamond pads in four inch. Keep the surface of the brick wet when using diamond pads.

    You can also get grinding stones for a four inch grinder and this may be your best bet. These stones last forever and have many uses.

      Hi Pat,
      you can get sanding discs for your grinder whether course or medium to take your slightly high spots off. The firebricks are not really that hard but you may use a couple of discs to achieve your goal. In my build, I used a special disc in my 9" grinder to finish the floor and to sand my slab of granite that I use to roll and prepare my bases. It is photographed and rather worn out but it did the job and did it well.

      See: http://www.fornobravo.com/forum/f21/...-4-a-2045.html

      for the disc in permalink #8 and the slab in #12.

      Cheers.

      Neill

        Pat,

        Do you have access to a belt sander? Thats what I used - a little easier to control. It took a few belts but it was smooth as a baby's butt.

          Thanks gentlemen, sounds like a good ideas all the way around. Les I do have a belt sander, do they make a paper rated for brick sanding, what grit level did you use.

            I believe I used 50 grit - just the standard stuff. You will blow through a few belts but it gets the job done.

                Re: Grinding high spots on oven floor

                Hey Les, was thinking about using a quarter circle for form like you did on your build, what's the best way to set that up? Is that just a 21" half circle (building a 42"_)

                  Yes. I attached a nail to go into a centerline hole in the hearth. Since brickwork is not perfect, I had to notch the vain every course so it wouldn't hang up as it turned. I used this approach before the "tool" evolved. It may be an easier approach.
