First time builder - lintels for hearth? - 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.

  • First time builder - lintels for hearth?

    I'm just starting project for modular pizza oven. Have laid 8" thick reinforced foundation onto which I'll build concrete block base. My questions are to do with materials for hearth. I have concept of using concrete lintels 100mm X 65mm (4" X 2.5") laid between the concrete blocks then topped with 12.5mm Hardibacker board, then either making insulating layer of vericrete & CALSIL board or just CALSIL board without Vermicrete. I figure maybe I'll need 4 lintels to bridge the 1.2M square gap adequately. Does anyone have any experience of doing this rather than pouring concrete hearth? Are there any risks or potential poor performance with oven? Cooking surface will be firebricks.

    Also thinking if I can use 140mm wide hollow dense concrete blocks rather than normal 215mm wide as they should be lighter to handle, with every other hollow filled with concrete - is this likely to be stable enough?

    Thanks in advance for advice - don't want to screw up through trying something new.....

    Hi, I had the same idea to use lintels. after giving it lots of thought I believe it would work just fine. definitely put the concrete board on top of that and you should be good to go. the heat will never reach the lintels and so what if it does a little???? you will have the concrete board, FB Board and firebrick on top of them so it should never be a problem. I ended up not using lintels since I strained my wrist digging the foundation by hand and found that the lintels that long are heavy. my two cents is that it should work.

      I think Rob posted the same question on three forums at the same time. It was answered here

        Hi Dagored- I posted in several places as I couldn't really decide where the best place was to get some responses. From the replies it looks like newbies was the best. Thanks for your answer - it differs from most others who think that the only safe way is to pour solid concrete hearth - I still think the lintels would be strong enough and a darn sight easier but we're in the minority. For my first build I may finish up playing safe and pouring concrete.

        I will post again when I decide and advise on the results.
