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.

  • Chimney design ?

    Hi, all.

    Now that I finished the foundations and the base I am ready to start with the real work...
    I'm designing my oven and wanted to learn about chimney design.
    how high should it be?
    where should it be located? (how far from the opening?)
    what should be the internal diameter?

    Please help.

    My oven will be (if everything goes well...):
    dome style.
    floor internal diameter 70cm (27.5 inch)
    internal height 30 cm (11.8 inch)

    Boaz.

    First, there are two approaches to flue/vent design.
    1. Sized so that all the smoke, even during start up, goes up the vent.
    2. Sized so that the fumes/smoke during cooking go up the flue (and not in your face) but the initial start up smoke may go out the front of the oven

    In my opinion, you are never going to guarantee that #1 will never happen. You may get a load of particularity smokey fuel. I would go with #2. For a 40 inch elliptical pompey if find my 7 inch diameter by 18 inch high vent perfectly adequate. Mine is immediately (1 inch or so) outside the oven opening.

      Thanks for that info.
      another question, please.
      is your chimney isolated? all the way up?

      Boaz.

        Do you mean insulated? If you use a commercial chimney system, yes, they are insulated. If you build a traditional masonry chimney, there is only an airspace between the flue tile and the surrounding masonry. Many of us insulated the entry and the transition to the flue, to prevent heat loss, but it's not at all mandatory.

          "is your chimney isolated? all the way up?"

          Yes. Insulated (double wall) all the way up.
