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.

  • Mortar Stains on Refractory Bricks

    Hi All

    So I'm about five courses high on my 40" (ish) dome including having completed the entry arch using refractory bricks http://www.fornobravo.com/forum/f44/...lia-15738.html which are a creamy colour and homebrew mortar 3:1:1:1 sand, cement, lime and fireclay.
    I have regrettably been somewhat slack in cleaning the excess mortar from the inside of the dome as it goes up. I've used a stiff brush to get the joints at least flush, but have some unslightly watery grey stains.

    I'm looking for tips on how bext to clean this up. On normal red bricks I'd use some Hydrochloric acid, but wonder if this would be suitable with refractory bricks, and whether this would compromise the strength of the mortar?

    Appreciate any feedback, or how others have approached this.

    Thanks

    Muriatic acid will do the job. It's nasty stuff and given repeated applications, will probably compromise any brick. If it's just a stain on the inside - let it be.

      It is an oven, not the facade on your house.

      If you do feel the need, make sure that you get a 100% saturation on the brick before you apply a dilute muriatic acid solution.

        If the mortar is on the inside it will just flake off with the heat of the oven so dont worry about it.
        By the time you have done the curing fires it will most likely be gone.
