Casting a cement vent - Forno Bravo Forum: The Wood-Fired Oven Community



Photo Galleries are back! Instructions below.

Dear forum users,
Thank you for your patience with the Photo galleries. We've got your galleries online!
We have finished writing a custom script to migrate the PhotoPlog to vBulletin5’s albums.

Unfortunately V-Bulletin killed the "Photoplogs" in their software upgrade which was unforeseen and we're the first development group to have written a script for getting the galleries back... that said, it took some time to reverse engineer the code and get the albums to move over seamlessly!

Forum users will be able to access their “PhotoPlog” images through their user profile page by clicking on the “Media” tab.
They will also be able to browse other albums by going to the albums page. (On the forum site, there is a link in the black bar beside “Forums” to the albums.)

In order for users to create an album please follow the steps below.
1) Go to user profile page and click “Media”
2) Click Add Photos
3) Enter Photo Gallery Title in the first field
4) Click Upload or Select from Photo Album to add photos
5) Click Post
6) Once posted, the album will be created as a “Topic” on the albums page for the public to see. The topic title will be the “Photo Gallery Title” they created before uploading their photos.

To create this migration path we used vBulletin5’s default album structure. Unfortunately, it won’t work like the “PhotoPlog” but is an album/gallery component on the forum now.

  • Casting a cement vent

    I'm thinking of casting my own vent, am i wrong in thinking that Portland cement will crack because of the high temperature ,what is the right material
    for it ? Is it really worth the trouble or should i just go with regular firebrick
    case for the flue????????
    Thanks for taking the time in answering this "newbie's" questions!

    The vent will get very hot. I wouldn't mess around with portland cement. There are special refractory casting products specifically made for this. I don't remember the names of the products, but they have been mentioned in several other threads. Try doing a search.

    You can always use firebrick. It's really not that hard and probably faster than building the mold, casting and curing.

    Good luck! Looking forward to watch your progress.

      The main advantage in building a firebrick vent is that it won't take ages to cure. Also, you already have the materials on hand from building your dome.

        Arigato,Ken san!
        I believe I will go with the firebrick idea.

            Masako...go with the firebrick. There's plenty of examples here and it's not that tough. Many of us have had no experience at all with brick and have managed to pull it off- just following examples here on FB.

            Good luck and take lots of pictures!

              Yes, share pictures with us! Do we have any other oven builders from Japan? This might be another first!

                There is at least one other in Japan - I sent the contact info to James (geeze has it been 2 years) a while back and he posted pic of the oven in the oven picture area.

                Here's the link to the pic above - for some reason the pic is not showing right now.


                It was a home made casted (in pieces) oven fed from the fireplace below - very cool. here's the link

                  On page 41 of instructions it tells you how to cast a vent, makes no mention of material except it says (let it set for several days so the "CONCRETE" can cure.
