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.

  • Cal-Sil Board specifications - more than one?

    I have been researching Cal-Sil Board sources and found a site that sells 2" thick board for $3.56 sqft. Looking at the specs (ASTM C 533, Type I) it shows a heat rating of 1200 degrees F (649 degrees C).

    The Cal-Sil Board sold in the FB store states a heat rating of 1200 degrees C (over 2400 F). (possible typo?)

    Now I suppose there are different grades or specifications of Cal-Sil Board. My question is, what floor temps are likely to be seen? ie if 1200 degrees F is completely adequate I can't see paying 3 times the price for board that will never come close to the temp rating possible.

    Thoughts?

    This is a question for our multiple-thermocouple mavens. How hot does the interior of the firebrick floor get at full temperature? I'd guess it's well under 1200f

      I think I'll repost under asking that very question. Thanks

        I have standard floor (flat bricks) and TC's with center of brick measurement. There is no way you are going to overheat the floor insulation on a normal pizza firing. The highest temps I have recorded for the floor mass was approx 450 degF. 1200 deg limit would be fine.

        What you need to look at is thermal coefficient as that is the more important number. You want the lowest number for your money. Also, some materials loose structural integrity when wet, so need to be aware of that.

        I used Insblock 19 under my floor at $1.00 sq ft for 1" thick. Haven't got any complaints.
