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!

  • David' flue

    David - is it recommended to taper the flue as you have done? Is there a known ratio between the top and bottom for the best draw? And one last bothering question, what adhesive did you use?

    Thanks,

    Re: David's flue

    I first used refractory mortar to attach the two halves of the refractory flue tile funnel together:

    I found the answer - I just didn't think that mortar was the magic bullet for this application. I thought there was some kind of magic mouse milk that would be better.

      The magic ratio for the top/bottom of the flue was the size of a single 8 by 12 inch flue tile cut on the bias so that that it mated with the 8 by 8 flue section at the top, and was as large as possible at the bottom.

      And yes, you have figured out that it's just adhered with heat-stop. Don't move it until it's had at least 24 hours to set up.

      The flue tile is MUCH harder to cut than fire brick. It mostly doesn't fit under the wet saw, so it has to be cut with the diamond blade in the angle grinder. I might consider building a flue funnel from fire brick splits if I did it again. I get a GREAT draw, but of course I have a good 16 feet of flue above my oven. With that much flue, It would probably draw with no taper at all.

      Of course, after today I have Swiss flue tile envy.
