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.

  • How about an earth/refractory oven?

    I don't really know what I'm talking about, but would it make any sense to build an inexpensive earth oven, but stabilize the earth mix with refractory cement, and make it modular for mobility? I really want the mobility feature, but of course, want to pay next to nothing for it. Any advice would be greatly appreciated.
    Thanks,
    Dan

    Earth ovens don't vitrify - they dry out and harden, but they don't become glass like fired ceramics. Moving such a thing, even a little, would cause it to crumble.

    Also any talk of refractory concrete is incompatible with talk of saving money. Boy is that stuff expensive.

    We all like to save money, and you'll find a lot of suggestions for that here, but you have some real problems with your idea as it stands.

      I got a quote from a local outfit here in Houston called Able of $27 for a 75 lb. bag of their lowest-duty refractory which works out to $0.36 a lb. (Refractory Castables, Refractory Plastics, Refractory Mortars) By way of comparison, my 9 lb. firebricks were $1.20 or $0.13 a lb.

      On the otherhand, REFMIX is about $2.50 a lb. HeatStop 50 is just a little less shipped from the factory. I have spent over $250 just on 5 bags of REFMIX.

      A Casa90 is 650 lbs according to the spec sheet. Let's say 150 lb. of that is the floor. The 500 lb dome could be cast for $180. I have NO IDEA whether "AbleCast" is an appropriate product. I have attached a datasheet. I would imagine that at the least, it is an upgrade option over "mud" or clay.

      The only cheaper option might be firebrick, homebrew mortar, and a chisel or angle grinder. A HF tilesaw alone makes the brick option more expensive than this.
