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!

    How are you guys drawing the arches. Not the half round but the more flat ones. Are you just useing a larger radius than what you have?
    Thanks

    Re: Drawing the arch?

    Mike, I approached my inner arch this way: I wanted my side walls/vent landing to be 3 bricks high. That equals about 8.5" at the sides. The FB plans and everyone's experience tell us the oven opening shouldn't go over 12" or 12.5". I went with 12", so that dictated the curve. If you go thru the PHOTO GALLERY, you see about half of us used 4 bricks stacked at the sides and half used 3. If you want a less "arch-y" entry and like the taller 4 bricks at the sides, your curve is less pronounced. 3 bricks and it's more pronounced. THEN you want to tapper most, if not all the arch bricks on their sides so each is a wedge to make the arch as strong as possible. Some just use the half bricks and mortar triangular joints to make the arch. All this mostly dictates the curve.

    On mine: I had someone hold and bend a 5" by 1/16" thin scrap sheet metal sheet between the walls (on the thin side of course) until I had pleasing curve, then held a piece of plywood behind it and drew a line, following the curve of the sheet metal against the plywood, careful not to push it out of its curve. The pencil line on the plywood became my guide to cut with a small jig saw. I cut 2 pieces and nailed them together to hold the arch up while I mortared. Hope this helps, Dino

      I used the software that comes with a tool you can buy at HD for $15. the Angleizer.
      Took some pictures on my thread. you plug in the span and height of the arch. it tells you the cut for each brick. genius.
