I'm Peter Reinhart! Ask Me Anything! Monday, February 15, 2016 7:00-8:00 pm EST

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.

Ask Me Anything New Forum Feature

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.

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!

  • Too Small?

    I poured my foundation yesterday. It's 12' X 40". The size was based on exsisting land marks, esthetics and the need to keep the drive way open to get a trailer past it.

    I am (was?) planning on making the the base stand 48" X 40" and canter-leavering the hearth an additional 8" over the front to give me a 4' square building area. Now I am having concerns that:
    - It is too small of an area for a 36" WFO (or at least adding a vent arch and landing area.
    - The strength of the canter-leaver portion if the hearth.

    Am I over thinking this, or are my concerns legit? I can easily make my base wider. I can also add to my foundation another 12" or so, but that poses many additional challenges. Any and all thoughts are appreciated.

    BS,

    A 36 inch oven will require more than the 40 you have - a standard build is:

    36 in. interior
    9 in. for the brick (assuming 1 brick cut in half)
    4 in. for insulation (2 in. of blanket - I would think this is minimum for insulation)
    1 in. for stucco.

    The above is for a dome - an enclosure would require even more space.

    The canter-leaver is not a problem if constructed properly.

      Thank you Les.

      I am planning on a enclosing the oven utilzing a 48" square base. Therefore I know that the insulation around the base will be "thin", as I plan on using 4" X 4" X 16" cinder blocks around it. I figured that as long as the hearth floor is well insulated, as well as the top of the oven, I should be alright. However, it doesn't leave me much room for the arched vented opening and landing.

      How far off am I in my thought process? Is it even doable? If not, what have I not accounted for?

        Is tied in rebarb enough? I'll probably add some wire mesh just to be on the safe side...

          Can you post a drawing of what you have in mind?

            Rebar is fine. Just make sure is goes into the hearth slab a ways and preferably has a bend so there is no chance of it pulling out

                The pics are too large and need reducing in size.

                  Here is what I started with. It's a 40" X 12' slab, as I am also going to build an off set verticle smoker.

                    Once I laid out the first coarse, I realized that there is NO WAY I can do what I want, so I am going to dig another set of footings where the oven stand will be.

                      The weather here has cooperated with my work schedule, but once it does, I will include pics of the new forms and foundation.
