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.

Hello,

For many of you who bought a modular oven, you may have asked how we put the domes together when we build them. For those of you considering one of our ovens, we shot a video to make your install easier.

Check it out on our You Tube Channel.

    That is a regular Type N mortar, with minimal refractory characteristics. That said, I have seen a lot of old fireplaces that were in heavy use and good shape that used it with 3/8" joints.

    For the effort required to build an oven, I would not risk it, though.

      If you're out to save money, I'd stick with the tried and true homebrew mortar.

      Here is the recipe for fire clay mortar, where you measure by volume (use a bucket or shovel to measure):

      1 part portland
      3 parts sand
      1 part lime
      1 part fire clay
      I know fireclay is a little hard to find in the UK, but it's worth the search. It's the only really refractory item in the mix. If mason's suppliers don't have it try pottery supplies. I haven't used the homebrew stuff, but it's said to work better if you get really fine sand.

        HI D,

        I'am a little surprised to see the lime in the mix, I thought that it would burn out. I have been mixing a fireclay mortar at
        2 parts sand
        1 part port
        1 part fireclay
        I would have to admit that the lime would make it easier to lay, If it had no ill effects. I learned from an old time brick mason, but that does'nt mean it was correct. any thoughts on this?

          The lime will not deteriorate with heat like the portland cement does over 300C. Use the 3:1:1:1 fine sand,pot cement, lime, fireclay. Be careful with the lime, use a good quality hand barrier cream and or rubber gloves. Hurts like hell in a cut and dries out the skin on your hands otherwise.

            I'm using the home brew for my oven and it spreads and sticks well. I use rubber gloves so no problem with my hands. I bought one bag each of fire clay, portland and lime along with a yard of fine masons sand. Plenty to do the whole oven.
