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.

  • questions on re-pointing 40 year old fire brick

    Hello and thanks for tolerating my ignorance. If this project did not risk burning by house down in a Rumford-style firebox, I would just use my physics knowledge and give it a roll.

    ISSUE:
    40 year old Rumford box needs some repointing, no less than 1/2 inch (UTLTIMATE MAXIMUM) and I have already removed weak or failed mortar with a wire wheel on an speed drill/

    SEEKING:
    Best recommendations on re-pointing mortar Mix. Purchased a product from "Rutland" but it only certifies to 2000 F where I know the fire bricks in my box can get a lot hotter than that (White Hot) on a cool night which I think is hotter than 2000 F.\\

    ADVICE: DIY MORTAR in 1/8 layers or use the Rutland? Please I need expertise./formulae?

    Thank you sincerely.

    I don't know much about Rumsford Ovens (as far as I know their distinguishing feature is a geometry which reflects more heat out into the room), but I would be very suprised if your oven was getting as hot as 2000F. Unless you are using a blower on it or burning something other than firewood, I suspect your peak temperatures would not exceed 1500F and the Rutland product you bought should be fine. Do you have a friend with a fireplace and a themometer that you can measure the temperature of the firebrick wall?

    Regards,

    PS: You might be more concerned about the chimney - as that is where most of your heat is going anyway. If the lower portion of your firebox is in need of repair I wouldn't assume that the chimney was any better.

      Your 40 yr old fire box was probably built with mortar or a portland/fire clay mortar. You should remove as much failed material as possible to a minimum depth of 1" before you repoint it.


      Normally you don't want to have any joints more than 1/8-1/4 wide when using refractory mixes. The temp rating is fine on the Rutland mortar ( they make good product) and it should be suitable for what you are doing. A portland/fireclay mix will be ok too.
