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.

  • How strong can you make perlite?

    I want to put a perlite top over 4" of 1" CF blanket....I don't need it for insulation. I'd like to fashion it in a tall hip roof configuration,think French ranch house. To be covered with approx. 1-2" of stucco type mortar and possibly using a cobble design roller or stamp. There is 9 courses of brick surrounding the oven with 2 1/2" of loose vermiculite between the oven and the 4" CF layer. Just about 10" sticks out above the surrounding wall...this will be where the perlcrete will be used. Can lime be used with the perlcrete? What type cement will give me a harder perlcrete? Repeating......not using the perlcrete for insulation.....The pictures don't show it ,but, there are 9 courses of brick surrounding the oven... The box around the oven is complete, just need the top....and the archway floor...p.s. the oven cleared in a hour with a armfull of white oak...kept it there for an additional hour,cooked pork roast, squash and potatoes, shut UN insulated door....30 hrs. later, still in the 300's..............whooohoooo.

    You can make up a standard 3,2,1 aggregate, sand, cement concrete mix and use the perlite as the aggregate. This produces a fairly strong result, but reduces the insulating capacity. If you want it even stronger then make the aggregate portion of the mix 50% perlite 50% standard aggregate. Be aware that perlite takes up a large amount of water that you need to eliminate later.
    I've just got a sample of expanded clay which is an aerated clay about the size of peas. It is about double the weight of perlite , but quite strong. I'm thinking of using the stuff in an application where strength is required. The trouble is that it is also around double the price of perlite.

      We have a product over here called Maximizer that uses expanded shale as an aggregate. It is tested to 5500PSI, but is a little tricky to use. The beauty is that the 80# bag = 1 CuFt whereas a normal 80# bag would cover .66 CuFt.

      Expanded shale by it's nature and manufacture is extremely dry and absorbent. It will flash set in about 40 seconds if you do not use pretty much the full dose of water to start.

      Perlite can be used to make lightweight concrete as noted above.

        Is that the understatement of the week!!!!

        Flashes in 40 seconds sounds like something I will avoid like some guys avoid their X-girlfriends.

          It is not a problem in a mixer, jut when mixing by hand.
