arched opening? - Forno Bravo Forum: The Wood-Fired Oven Community



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.

  • arched opening?

    Jim posted this photo of a pre-fab FB oven today.

    Is there any reason that home builders don't build this style of semi-circular entrance arch? We see so many ovens crack at the thin arch top of the usual style rectangualar or shallow arch opening. It seems that this would be stronger, as well as being easier to tie into the shape of the dome.

    I think 2 reasons:
    1) The bricks pictured all appear to be tapered, with the bottom brick on each side appearing larger than a tyical firebrick - Tapered bricks can be very expensive; the local refractory supplier (the only place within 100 miles who stocked them) had prices that started at $4.50 per brick and wnet up to nearly $8 depending on size and degree of taper.

    2) Novice builders are a bit intimidated by the geometry involved and more importantly the skill they think they need to accomplish this. Remember, the basic Pompeii plans really don't call for anything more than right angle cuts and 1/2 bricks. Personally, I had done considerably BASIC stone, tile, and masonry work in the past and I too fell into this category to some extent. I actually started with the arch and entry, then proceeded to the dome where I tapered every brick...I think the confidence I gained building the arch and entry was the driving force behind tapering every dome brick and attempting as tight a fit as I could achieve. Bottom line, I think many believe arches to be difficult and as I mention, a bit intimidating. If I ever build another it most certainly will have a more decorative and supportive entry/arch.

      I built a catenary-type flue arch from tapered blocks but apparently was a bit careless when mortaring in the keystone: resulting in fine cracks on either side of the keystone. And on advice of the supplier of tapered flue and door arch bricks, I started on the twin arches FIRST and only then began laying the dome bricks...

      Still think the arch itself is nice and stable, and the tapered bricks worked very well. I'd recommend this type to other dome builders - just take extra care with the keystone!

        Just for clarity, I should point out that the archway on the Modena is cast as a single piece. The "brick" look comes from the mold they use. On the sides, it's nearly four inches thick. There's a slot in the top into which the metal vent fits quite nicely. Good thing I had help to get it into position.

        The next one I do, I'll take photos of it from various angles. This might help.

          I'm seriously contemplating opening a pizza establishment with a financial partner. So.. I've been checking out ovens.
          I think I am leaning toward gas fired... (I don't want to live at the place taking care of a wood fired oven) I've been checking out James selection of gas ovens for commercial use.
          Have you had much experience with these types Jim?
          And can they put out 60 - 70 pies an hour?

          Anyways.. I thought I'd ask.
