New Forno Bravo Forum Feature

Forno Bravo Forum Community,

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.

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.

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!

  • Repair question, need help

    I have a two year old WFO than I did stone on the outside of the dome which I now know not to do. The heat caused it to crack and water keeps my vermiculite soaked now, so I have to figure out which way to go to fix. One kink in the deal is that the base of my oven has a rounded back so it make building something square on top of it a little tricky. I was thinking about going one of two ways, either doing a stucco cover on what I have there now or pouring a square concrete ledge around the top and building off of that (after some serious reinforcing of course). Would appreciate any input. I would hate to build a freestanding structure to cover it just because of aesthetics, but????? If I do stucco is there a link on here on what will work? Picture of it below.

    If it were me, I would think about putting some sort of roof extending off your pergola....I think you could make it look real nice and intentional. Stucco on outside of oven would be a travesty considering the nice stone work you did....

      Sorry I was unable to view the picture you attached. The pictures on the other threads open up ok so I am not sure what is going on here. Anyway I would really like to see your oven, I read somewhere that it has a real good look.

      BTW I am also a motorcyclist and I'm also amused by the alternative meaning for "WFO" - as in "When this snow clears I am going to go WFO to finish my WFO so I can go WFO on my bike!"

        Looks like we enjoy less than mainstream motorcycles, too. I have Gasgas now, almost bought an ATK back in the day, even talked to Horst about it. I was doing some magazine work then and was going to do a write up, but it all fell through.
        Anyways, you can try my Flickr site, thats where the pic was linked from, Flickr: bkdjr2000's Photostream . Few moto pics on there, too, excuse family stuff.
        Do more mtn biking these days than moto, but it seems to go in cycles.

          I agree that it would be a pity to cover that nice stonework. If it were mine I would use an elastic acrylic product to fill any cracks in the mortar to prevent water intrusion. You will never completely waterproof your oven, short of covering it with a roof. After heavy extended rain periods your oven will get wet through the entry even though you may have the dome totally sealed. A couple of long gentle fires restores the oven to normal operation. We live in the tropics and our infrequent rain usually get measured by how many times the rain gauge overflows. Our oven is out in the weather.

            Hi David,

            We live in the tropics and our infrequent rain usually get measured by how many times the rain gauge overflows.
            I heard yesterday that you got around 120 - 160mm of rainfall in the 24 hours just west of Townsville.
            A very welcome for the drought affected graziers but a bit rich for the city dwellers.
            Anyway, I hope you are app OK.

              Yes we also got another 100 mm the following day.

                I'm with jeeppiper - seal the cracks and extend the roof on your pergola over the top of your oven -maybe use some steel roofing to keep the direct rainfall off of it. Hate to see you cover that nice stone work on your dome with stucco (which is just as likely to crack anyway).

                Nice pictures on Flickr btw. I've thought about getting a Gas Gas to upgrade my trials mount (I've got a '86 TY 250 that I ride now). The ATK has been a great bike - I don't do so much motocross but I love it in the woods - short wheelbase, light weight and lots of torque. Mine is the 6 speed Cross Country version so put it in 3rd or 4th and it's almost like riding an automatic. Very cool that you actually got to talk to the designer. Mine is a '92 which is one of the last years that they actually made real ATK's (with the idler sprocket and countershaft mounted brake).

                Good luck on your project and keep us posted on what you decide to do.

                  To the OP's question - I don't see how the thing ever gets dry if you seal up the top. Seems to me that you're likely to need to remove the stone so that the insulation can dry and then cover it with something water tight. I like the first suggestion of extending a cover off of your pergola that would keep most of the rain off of your oven. Just extend the chimney through it

                    Vermicrete is a good insulater. But, I think that is unless it is fully dried before ramping up the temps, it will help to have an expansion joint between the oven brick and the insulation. Ceramic Fiber blanket worked great in my case. In your situation, to keep from removing those great looking stone, I would fire it as much as possible to remove all moisture. Then I would place a vent at the top to relieve any further mosture that will be trapped in the oven. Then, I would patch and seal. But also, do as Dennis recomends. Put a roof over it

                      More than agree with the vent , it a good to have but its only usefull when the ovens damp and unusable. Prevent the water from getting is really what you want. If you don't want to cover it preventing the water from getting in is your aim. The cracks are from water trying to escape. A water tight cover on the front of the oven and a water tight chimney cover is your best insurance. Keep the water off that entrance brick. Take a cup of water pour it on the entrance hearth it will not be there long , its straight down those cracks and straight into those bricks. Then its into your insulation and from there its a long slow process to remove.
                      I like my oven in the open and have tried everything. Keep the hearth dry is the most successfully. I only did my final finish after being able to keep it dry

                        Yes that's him. Quite an innovator. Well you would know better than I...I only purchased one of his creations. I always get alot of attention out on the trail..."What is that?"..."Was it made in the US, do they still make them?" etc...You should hold onto that bike, it might be a collectors item some day. LOL Thats what I tell myself about my ATK but used ATK's are usually pretty cheap...or unsold.

                        But enough about Horst! What is Ken going to do with his oven?....take more pictures I hope!

                          I agree with that. But, without being totaly protected from inclement weather, humidity, and long periods of unplanned unuse, the vent is a great "fail safe" .
