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.

  • smoke temp at chimney exit

    Can someone tell me how hot the smoke is coming out of a 36" chimney at the hottest time of fire building? We have a telephone line 48" directly above where we want to put our proposed chimney exit using a 36" tall chimney pipe.

    Thanks

      It's gotta be well in excess of a 1000F.

        I had measured 1200 C degrees (+2000 F) at the entry of the chimney on fire running.
        Move the fone line or use a cone or mushroom top on the chimney.
        Burning ashes must be considered, too.

          Wow, I'm surprised. I almost didn't ask the question. I would have thought the temperature would have dissipated more by then (48" from the exit of a 36" chimney). Yes, I am going to use some sort of spark arrester/cone anyway. I have an alternate location I can put the oven in. I will do that. Moving the phone line would be a hassle,... it's the neighbors phone line (living in the city sucks). Thanks for your input.

            Oh, if it is the neighbor's phone line...I think it will be just fine

              I measured 120C at base of chimney(using laser non touch thermometer) and no more than 80 at the top(4 foot). Internal temp of oven was 500c ish.

              Not too sure how acurate this thermometer is, but soo o inside of oven had burnt off, meaning the oven was well over 400c. Also, chimney was 8" which may effect things.

                120 C sounds more accurate to me. I think someone slipped a decimal point.

                  Your chimney tile would be glowing bright red at that temperature. That's cone 6 in ceramics, just short of stoneware temperatures.



                  Time to re-calibrate that instrument.
