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.

  • Actual foundation size for a 42" oven

    Hi,
    I'm a newbie living in Prescott, AZ, and have started excavating the foundation for a 42" pizza oven. My question to all of you that have built ovens before me is what was the actual foundation measurements for your oven as the ebook actual has 2 different size foundations for a 42' oven. Any feedback would be appreciated.

    I am about half done with my dome. I used the 77" by 86" size for my foundation. Hope that helps.

        My foundation slab is 88x79. Here's what went into figuring that number: My stand is 5 blocks by 4 1/2 blocks. I wanted 4 inches of reveal on the sides and back with 6 inches of reveal in front (for us non-techies, reveal means the part of the slab that extends beyond the blocks that form the stand). The blocks are 8x16, except they are about 3/8inches less than that for mortar. I urge you to dry stack them close together, so they will be 3/8 inch shorter and narrower than 8x16, totaling about 78 by 71. Adding 10 inches to the length and 8 inches to the width gives 88x79.

        I did a 10 inch curved cantilever, so I ended up with extra room at the back, so my foundation could have been shorter, but I'm not sure it could have been a half block shorter. The primary consideration after making sure it will be big enough for the oven and the insulation you plan (a blanket will take up less space than loose insulation) is to not have to cut blocks.

          You got frost heave in Prescott. Are you planning footings or a floating slab?

            Hi Joe,
            You are correct in the frost heave in Prescott. Because of the oven location, I've had to excavate, by pick and shovel, quite a few cu yards of dirt. I was planning a slab over several inches of 3/4" rock and hope that qualifies as a floating slab. What do you think?

              Six inches of crushed rock should suffice, if the area is well drained. If you are building in the lowest part of the yard that floods when it rains, then more may be required. The idea is that if there's no water, there's no frost heave.
