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.

  • oven dimensions

    Hi - hope somebody's out there.
    I've just started building an oven base from old bricks, but my dimensions are limited. The base will be about 110cm x 150cm.
    Assuming a total thickness of 20cm for the walls, that means I will have an oven with an internal diameter of about 70cm.
    Has anyone used an oven this small? I think it would be quite adequate, but all the ones I see on this site are so much bigger!
    Alternatively, could I take the brick section of the walls right to the edge and form my insulating layer, which I'm planning on doing in clay and chopped straw, as an overhang, moulding it back in to meet the side wall of the base?
    Then I could have an internal diameter of about 90cm.
    Another possibility is somehow forming the concrete slab to extend beyond the sides of the brick base.
    It's probably obvious, but please assume I'm a rank amateur if replying to this.
    Thanks, Rhonda

    70 cm = 27 1/2 inches
    90 cm = 35 inches.

    I think you will be a lot happier with the larger size. Also, at the "pinch points" of the insulation layer, you can use the insulating blanket material. (go to your local dump and remove some from the liners of old electric ovens)

      Hi Rhonda,
      I would just cast the slab larger than the base, and make the oven in the 90cm (or 1m) size.

      70cm is on the small size, not unusable, but probably limiting.

      hope this helps...
      Mitch.

        Re: oven dimensions

        How is the smaller size 'limiting'? Surely you have less space to heat? If the perspective was to cook one item at a time (or so many small)-- your deciding factor is space large enough for your item to bake -- to accept what ever hardware you cook in or the item -- its height and width. In that sense the size of your oven door would rule, wouldn't it, rather than the size of the oven? (eg: one figure suggested by Canadian research was a door height 63% of oven height)

        The only limitation I can imagine with a smaller oven is that it would be more difficult for a baking item to share the space with a smoldering fire.

        My everyday kitchen oven(electric) is much smaller than these figures....and I rely on that day in day out.Similarly a Dutch oven is as big or as small as the one you bought.

        Unless there is some physical principle involved, ovens could be of any size -- although their shape should be ruled by the way hot air flows.

        size doesn't seem to be a constant.Although there is a mean I guess -- judging on these images -- esp for community ovens.

        If I'm missing something I'll need to redraft my oven plans as I, like Rhonda, was planning a smaller oven.

            Your oven's heat control is the placement of the food. A tiny oven with a fire really only has one place. Mine is 36, and I really wouldn't want it much smaller.

              I'm a believer in small is beautiful. There are just so many advantages. Mine is 22" diam and I've cooked pizzas for 40+ parties. I's all a matter of oven management. Nearly all home cookers cook one pizza at a time anyway.

                Rhonda I built my base with the slab on top and the realised I need more space for my entry. My solution was to over hang my insultion slab to give the space I needed which has worked just fine. If you have a base and you can place a concrete slab on top that is properly reinforced you will have no problem with a 20cm over hang all around your base and that will give you the room to work with. Thake a look at the link below and you will see how I have a front and rear over hang, 41# shows the over hang. Good luck and you are amongst freinds here that are here to help.

                  Re: oven dimensions

                  Thanks to all for the responses - I think I've worked out what to do. I only need to extend the base a little on each side to build an oven with a 90cm (35 inch) diameter. The smaller size would be fine for closed oven cooking, but I think for fast cooking pizzas with a fire in the oven it might be a bit small. I am planning on having it up and running for my son's 18th - umpteen hungry boys waiting for a feed.
                  Since you've all helped to clarify this for me, I'd like to ask another one. One site I've looked at recommends against chimneys and vents, saying the oven draws better - cool air in at the bottom of the door, warm air out at the top - without one. Any thoughts?

                    This only works if you don't mind smoke in your face while cooking. The collective wisdom of the forum says you absolutely need a chimney. There are also tons of threads discussing chimney size. You will need at least a 6 inch diameter flue. Also the taller the chimney the better the draw.
                    Maybe what they are talking about is a chimney in the middle of the oven. All of the Pompei ovens have the chimney over the entrance. Download the Pompei plans and look them over. They are free on the forno bravo site and contain a terrific treasure trove of practical oven information.

                      Re: oven dimensions

                      For my first oven I built it with a flue in the centre at the top of the dome. t would draw beautifully and had the advantage of taking up less space (with no flue entry and also no need for a flue pipe. I made some caps,one with a 50 mm hole to choke the oven and reduce heat loss and another plug to fit into this hole to totally shut the oven. More heat is lost up the flue with this system and a greater heat loss occurs from around the top of the dome which you can't totally insulate.

                        We visited Pompeii in October, what a fascinating place! Among other very interesting things there were wood ovens. I was surprised to find that they were not all of the front flue design. There were a couple there that had central flues. These were generally smaller in size, probably private homes rather than commercial premises.
                        The first pic is from the bakers shop. The third one has a central flue and the last one I think was just a cupboard.
