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.

  • Perlite Ratio

    Hello everyone

    What is the ratio of perlite, cement, and sand to build a pizza oven dome?
    What is the thickness required to build the dome before the layer insulation?



    Thanks

    Thanks
    If you build the dome with perlite in the mix it will not be dense enough to store heat.
    Generally the dome thickness is between 2-4" thick depending on the materials used.
    Suggest you download the free plans or read lots of build threads to get a better idea of design principles.

      Thanks

      I have just design and built the first arc already (attached a picture)
      Now I have to build the rest of the oven and I wanted to build from perlite and cement
      But I do not know about the right ratio

        Like David said, you cant build an oven out of perlite and cement, it just wont work.

            Use a dense castable refractory. Search the forum for this material and read all you can. You can buy the stuff from a refractory supplier.

              Perlite and its neighbour Vermiculite are insulators, and wont hold heat. As David S mentioned use a Refractory dense castable, a 1350c grade is most likely the easiest and cheapest option. approx $25-$30/25 kg bag.Dont know the size of your oven, but if you calculate the volume of the prefered dome, you can use the 80 bags/m3 figure to work out your requirement, or if your old like me, 2 bags/Ft3. THEN use your Perlite mix over that dome to keep the heat in.
