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.

  • Suitable for under hearth insulation?

    Hi could someone tell me if this board is suitable for insulation under the cooking floor?

    Block 607 Board-France - ceramic fibre, thermal ceramics, refractories, insulation bricks, castables, ceramic fibre paper, ceramic fibre board

    It's Blok-607 800 I'm looking at. 800C max temp is MORE than adequate as far as I'm aware?

    It looks OK to me but I'm no expert. Would 2" (50mm) be OK directly on top of support slab? The stated thermal conductivities are for a board thickness of 2".

    Dont know importance of linear shrinkage or loss on ignition or modulus of rupture!!

    Any help greatly appreciated!

      bensdb,

      Sorry can't help much,,,

      We are looking, but without experience with the details, any opinion wouldn't get the job done.

      Give the post a little time, maybe someone with the correct education will see it and weigh in...

      Good luck, glad to see you're building and oven!

        Hey jed thanks for the input!

        I've managed to source ceramic blanket, with the same specs as the fb blanket, for a good price.

        The board is proving a little more difficult though.

        The same company who produces the above board also produce a board with the same specs as fb board but it's about 5 times the price of this one, and the only difference I can see (other than completely different chemical composition and price) is the fact that it's only rated upto 800C instead of 1260C!

        So still not sure whether it's suitable really! Certainly can't figure out why it's so much cheaper. Maybe I'm missing something obvious here?

          As far as the insulating properties I see no reason why that would not be usable...the only question I would have is to be sure that the board will be able to support the weight of the brick oven...another builder on the site had some issues with the board compressing when it got wet and I believe his was a mineral wool product also...I think it was Ken...
          Good luck and all the best!

            Is 2" "blueboard" which is use in standard construction, suitable for insulating under the oven floor or is it not used because of the heat? It seems like it would be strong enough .How about if it is covered with fire clay before laying the floor?
