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.

  • Slab Recommendation

    Hello All,

    My build is a self designed 38" oven of brick. I'm ready to stack blocks for the top slab and need a recommendation for rebar reinforcement, or none at all. The inside, unsupported dimension, is 36 inches by 48 inches. The outside is 52" x 72". The slab will float without tie-in. The ground is stable, no frost heave and no geological faults.

    The front opening will be supported by one row of block on top of two iron angles. I'll be using high strength 5000 psi concrete mix in bags from the local materials store. The form will be made of 2" x 6" wood but the slab will be 3 1/2" thick and poured over 1/2" cement backer board. There will be a temporary wood board placed in the center to hold up the backer board as shown in some fb forum photos. Am I doing this right or do I need rebar reinforcement? There seems to be controversy about this.

    Second question: The materials store offered a variety of sand in grade sizes from 40 to 120 for the fire clay mortar. Is there a preferred grade for oven mortar?

    I appreciate your guidance in advance.

    Cheers
    Bob

      Your slab does need rebar, You should be making a grid, 12 to 18" on center with minimum 1/2" bar. The backer board is a waste of time and money, just pour the slab 3.5" thick with 5000 psi and your good to go.

        The mesh sizes for sand is the coarseness of the sieve: bigger numbers mean finer sand. I'd go for the fine stuff.

        No controversy: only a few people wanting to put rebar in the insulation layer where it does no good. You need to reinforce your support slab.

          Thank you NicTL and dmun.

          I found a site that shows how to tie rebar. I just happen to have the proper tie wire. I'd been using it for other projects. The top slab will have reinforcement.
