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!

Dome Installation Video - Casa / Premio / Modena

Hello,

For many of you who bought a modular oven, you may have asked how we put the domes together when we build them. For those of you considering one of our ovens, we shot a video to make your install easier.

Check it out on our You Tube Channel.

If the link doesn't work, simply go to You Tube and type Forno Bravo Channel. The video title is How to Set your Forno Bravo Oven Dome Pieces.

Thanks for participating in our Forum. We will have more video content available soon.

  • concrete lintels instead of pouring concrete

    Has anyone tried just setting 8" x 4" lintels across the base instead of pouring concrete? it would be more costly but one heck of a lot easier. then set the FB board on the lintels.

    What part of the oven are you referring to? If you mean the upper platform, they will crack and probably collapse. Concrete doesn't have much bending strength which is why you have to add steel reinforcing.

      Assume you mean 8 feet x 4 inches? not sure what is gained by an 8 inch x 4 inch lintel

      But 8 feet sounds like it would be an awkward length to use. Most hearths are maybe 6 1/2 x 5 feet.

      And pouring the concrete is really not so hard, unless you have a place that is super difficult to reach. My pour was at the top of 50 stairs - and I still would have rather carried 80 lb sacks of concrete than ??? hundred pound lintels.

        Concrete lintels are 8" high to match standard block. They put rebar in it so it is strong enough to use across 8' garage doors and 3' man doors. any concrete company will cut them to length for you so my wife thought "why not use them instead of concrete to make the hearth base. in my case they would be 70" long and 8" high and 3.5" wide. To span the entire hearth you would need 27 of them making it a little pricey but easy. In my opinion they would not break.

          I am sure that they would hold up anything that you would build into a WFO. The rebar is more than likely prestressed ,making them even stronger than the equivalant beam that you would pour on site. If it were me I would pour the concrete, you will pour enough $$$$$$ into this project before it is over .

            Good point. yesterday I made that decision to go with the poured concrete instead of the lintel idea. try to save some money.

              I only used a concrete lintel to span the wood storage opening. It works great. Those things are heavy. Prefered this to using angle iron to support the span for the blocks.

              Just starting my 42" build. Will be moving to Pizza oven floor this week.

                I did the same. I bought the steel for $11 bucks and then made a dry run with it. did not like it from the get go and drove 15 miles to get the concrete lintels before the cement place closed at noon. way better. i see you mortared your joints. I didn't do that but did fill the entire base with rebar and concrete. we are pouring the hearth base on saturday. just found out today that the FB Board and blanket cost with shipping is unreal. over $700 just for those items. good grief! if I had known that cost I would have opted for the vermicrete mix. good luck with yours.

                  You can also form up the sides and underneath with with lumber or plywood and pour the lintel monlithic with the hearth.

                  It gives a little more head room.
                  I formed an arch on top of mine but it can be formed straight as well.
