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.

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!

  • Fiberglass Dome Roof

    Just curious if anyone has ever tried a fiberglass dome for their roof on a portable oven? I am thinking of replacing the stucco roof on my mobile oven as it is starting to show cracks and will likely need replaced. I am not sure what the best method would be to attempt it but I am thinking of using a bent metal bar frame for it and then using applying the fiberglass on top of this to form a dome. After several layers, I would apply some UV resistant paint to finish it off. Just a thought, I was hoping to get some feedback though first.

    No I haven't tried it but can see how it could fairly easily be done.
    I used to do fiberglass work in boatyards and am familiar with working in the medium.

    My suggestion would be to build something like I did ...see post:

    And then add the 1/2 hardware cloth to sort of look like:

    And instead of the window screening to hold in the loose vermiculite simply cover the exterior with a couple of layers of 1 1/2 ounce mat and then invert the shell and coat the inside with a layer to bond thru the 1/2 inch spaces and adhere to the birdcage. Fairing to look hemispherical will be challenging and I would suggest you consider alternative shapes or forms. A couple of other things to consider are cost: resin is no longer inexpensive nor is glass. But if you go that route I would suggest you coat the exterior with proper polyester gel coat using a fine nap roller. The fine stipple will hide a great deal of the imperfections and it's a lot easier than spraying.

    You will want to work out the transition to the heated interior at the entry as FRP breaks down before 500F. I used high temp silicone between my shell and the steel wheel rim of my transition and so far (5 + years) I have had no issues with it.

    Hope this helps,
    Wiley
