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.

Dome Installation Video - Casa / Premio / Modena

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.

If the link doesn't work, simply go to You Tube and type Forno Bravo Channel. The video title is How to Set your Forno Bravo Oven Dome Pieces.

Thanks for participating in our Forum. We will have more video content available soon.

  • Moisture meter for assessing "cure"?

    I bought one of these cheap-o moisture meters at HF a couple weeks ago, thinking it would be useful for checking firewood moisture content

    Digital Mini Moisture Meter

    It occurred to me last night as I was lighting up the chafing fuel for the first "flame" day of my curing, that the moisture meter might be useful for checking curing status?

    I took a couple of readings just to test the theory. It did show that the bricks laid earlier were much drier than those in the arch laid much later - but reading the instructions today I think I had in the wrong mode.

    Gonna check again tonight using the "hard materials mode" - but I was wondering if anyone else had thoughts on whether or not this is useful?

    Hi Deejayoh,

    I use high end moisture meters in my work regularly and IMHO, I think this meter will give you and idea of mechanical water content but probably not chemical water content. Eventhough I am not a the curing stage in my build I suspect the curing is to remove both mechanical and chemical water content. I would interested to hear what other WFOs have to say.

      I was thinking that there is the moisture left in the bricks from sitting out in the rain and running through a wet saw, and the water in the mortar, but not even the google could help me with "chemical water content". Does that mean there might be some water content that is released via reaction generated by the heat of the oven firing?

      FWIW, it is a $10 chinese tool - so I am not expecting much

        Deejayoh,

        Here is some info. But thinking about it more I think this type of water plays such a small role (fire clay) that the mechanical water reading will be a good indicator.

        Water within the clay lattice or near the surface within the electrical double layer. This water does not move when fluid is flowed through the rock. In the normal definition used by a log analyst, clay-bound water is not part of the effective porosity and is the difference between total porosity and effective porosity. Clay-bound water is understood to include the interlayer water, although the contribution of the latter to the electrical properties of the clay may be different from the water in the electrical double layer.

        In the dual-water and the Hill-Shirley-Klein models, the volume of clay-bound water is related to the cation-exchange capacity per unit volume, Qv, by expressions that depend on the salinity and temperature of the electrolyte in which the clay is immersed. Direct measurement of the clay-bound water volume in the laboratory is difficult.

        I am a engineer and I don't understand half of this so have a beer and move on.

          Thank goodness you said that. I was halfway through that and my head was spinning. And as a matter of fact, I am having a beer!

          FWIW, I took some quick readings on the right setting and it seems to vary from 0.5% to 1.1% moisture content. Out of curiousity, I will keep measuring it as I cure to see if anything changes.

          Edit: I just went back and took readings inside the arch, where the heat has been flowing into the flue - and there the moisture content is 0.0%. Maybe there is something to this.

            It is the residual moisture in your insulation layers that takes the longest to drive out.

            You need patience at this point.

              Checking tonight after 3 days of curing, the meter reads between 0.2 and 0.5%. Mostly 0.2-0.3%. It does seem like you can somewhat measure the residual moisture content. At least it's moving in the expected direction

                Keep on firing. It takes a while to drive all the water out. Maybe a week of constant firing will get you close to dry. At that point, forget about it unless it rains on your oven or something, you will never think about it again.

                  Could you describe, please, how exactly you are going to use moisture meter for your goal? I couldn't figure it out, so far. If I understand it - probably I would be able to help you.
