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.

Dome Installation Video - Casa / Premio / Modena

Hello,

For many of you who bought a modular oven, you may have asked how we put the domes together when we build them. For those of you considering one of our ovens, we shot a video to make your install easier.

Check it out on our You Tube Channel.

  • 6" vs 8" interior flue for 36" oven?

    I realize the general spec is 6" for 36" and 8" for 42", and I realize that going too small is worse than going too large...but...would an 8" flue definitely not be too big for a 36" oven? I'm not sure what the risks are. Extra heat loss perhaps? Nonideal airflow?

    Thanks.

    Lots of us have 8 inch square flue tiles on thirty six ovens, which are even bigger than round ones, and mine, at least, draws like a champ.

      Re: 6&quot; vs 8&quot; interior flue for 36&quot; oven?

      I've been using my 42" oven for about 9 months now, and the biggest mistake I made in the construction was using a 6" flue instead of an 8" (it was easily available, and the 8" was going to be hard to get hold of at the time). The smaller flue draws really well but just cannot handle the amount of smoke, particularly when starting, or when the wood is a bit damp, so a lot of smoke goes up the flue OK but a lot also comes straight back out through the front arch opening into the operator's face!
      The other mistake I made, although not a big one, was that instead of a poured concrete base supporting a layer of vermiculite and then firebrick hearth, I used a base of AAC panels to support the firebrick hearth. Quick and easy, but not really a good enough insulator, so in spite of having a well insulated dome, I lose a lot of heat through the bottom of the oven and it cools off quicker than I would like. Ah well...next time...
