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!

  • 40inch - 150mm v's 200mm Chimney????

    Hi there
    I have finally got to the outer arch and vent of my 12 month build of a 40 inch pompeii oven and now I have the question to 150mm or 200mm vent. I can get both pre fab, the 200mm one takes a few extra days to get in and cost a bit more. So I guess I am seeking advice from all you experts out there..... can I do with just the 150mm. Your wisdom will be greatly appreciated. Thanks Kriso

    Hi Kriso,

    A fine looking dome! According to the FB plans, a 36" or smaller oven may use a 6" (150mm) chimney, but anything larger requires an 8" chimney. I built a 32" dome and use a 6" chimney and it draws just fine. I'm not sure if it would have the same effect with a 40" dome or not. My thinking is that with all of the time and effort (and money) you put into the dome so far, why risk it? If it doesn't draw smoke well up the chimney, it will come pouring out of the front door...not the desired effect, especially if it starts sooting up your arch. I would spend the extra few dollars and go with a sure thing. I vote 8"

      I'm with Gene. One cannot 'over-flue' one's oven and it's more pricey to retrofit than fit. Especially with soot stains coming out of an as pretty as yours.
