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!

  • Is a 4x8" flue liner too small for a 42" dia oven?

    I just got a 4x8" flue liner and looking at it makes me think it might not provide enough draw for the relatively large Pompeji oven.

    is this really big enough?
    How tall should the chimney be? Does it matter?

    I was planning to notch the two vent arches and set the flue liner on top of the arches. (only the first vent arch is shown in the picture. Another one planned about 4" in front of the shown arch)

    Well the recommended sizes for the ovens in the FB family are 6" diameter for the smaller and 8" for the larger ovens. And as I remember the oven plans recommend 6" by 10" opening for brick or clay flues. I would say go with something bigger so you don't have to worry about smoke in the face.
    Oh, by the way nice work on the oven so far.
