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.

  • Insulation question - loose or solid vermiculite covering?

    I have built a fire brick dome (approx size of Casa90) and the surrounding walls. I have lots of vermiculite for the insulation. I was planning to just pour the loose vermiculite in the gap. Or should I mix with cement for a solid covering over the dome? Or does it make no difference...?

    Thanks

    By adding cement and water to the vermiculite to make it set will add considerably to its density and hence reduce its insulation value. Also the water needs to be removed because wet insulation doesn't work well and the steam it produces will create problems. If you can add the vermiculite loose it would be better although there may be a possibility of the vermiculite leaking out if you got a hole in the side of the enclosure.
    Kindled with zeal and fired with passion.

      Thanks - just what I was thinking.

      There is no danger of a leak - the enclosure around the dome is brick - if that gets a hole, leaking vermiculite is the least of my worries

        For all us Newbies in the UK, where did you get the vermiculite from and is there a particular type/description we should look out for?

          Hi Pault99

          I could not find cheaper Vermiculite than from here:
          Vermiculite V4 100 Ltr 429758 : Wilsinc

          I got 5 bags (so got free delivery) - I have not used it yet (should do this weekend) so can't be 100% sure this is the right stuff - but I think so. I believe any Vermiculite (called Micafil a lot in the UK) for loose insulation is fine.

          I might have bought too much - so might have some going soon.

          Also see my other thread in the barter/trade forum, where I might have some storage heater bricks going cheap soon - cheaper than the 2.50 per brick I paid at the local builder merchant !

            Does anyone know if you can use packing vermiculite, grade 4, as seen in photos attached.
            I can pick some up but, need to know if it can be used?

            Thanks, Bob

                Have you searched for questions on UK materials? Midland Refractories and somewhere in Sheffield seem to come up most often as recommendations. Have a look around and you'll find a few threads with suggestions in.

                cheers,

                ps - I used Midland refractories, for what it's worth. Small quantities are fine, but the delivery charge is steep.

                  Hey guys,

                  We are close to having FB UK set up and stocking accessories, including oven tools, insulating blankets and chimney pipe. If you are on a deadline -- don't wait for us. :-) Otherwise, stay tuned, and we will let you know when we can start filling orders.

                    You would have a local Thermal Ceramics or Morganite agent nearby.

                      Hi Bob,
                      I used the ULINE vermiculite, But i read somewhere here in one of the forums to use grade 2, Which is what i did, I can tell you it's working fine. Grade 2 is about half the size of what you have pictured. Try doing a forum search for ULINE....

                      Good Luck

                        I actually purchased the Uline Vermiculite since my intial post of this topic. I bought just what I pictured in my post grade 4. I plan on using it as loose insulation in an enclosure oven build. I had to buy it once I found out it was safe and Ok. I bought 6-4 cubic foot bags for $8.00 US a bag, a good deal I think, no kidding.
                        Thats all the guy had.
