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.

  • Chimney Draft Issue

    Just installed a 47" Modular oven in a trailer. The Door opening is 22"x 13" to the top of the arch. If I do the math its 286 square inch opening minus whatever the arch takes up. I used a 36" tall 6" insulated chimney. From what I gather the chimney should be about 10-15% of the opening 6" chimney is 28.27 square inches.

    With all that said I am having issues with the Draft. I have a good deal of smoke coming out of the front. Mind you I am burning a small fire at the moment, still curing right now. I also do not have a rain cap on so I'm not sure if the wind is causing issues. Any ideas if when the oven runs hotter the heat will help increase the draft or if I should add another foot of chimney on??

    1. New, wet ovens are notoriously smokey
    2. A 6" pipe is way too small IMO for a 47" oven.The 10% rule might be OK for draw once the oven is pretty hot, but it is inadequate at start up, when you are trying to pull the flame sideways. Should use 15% of oven opening as a min IMO.
    3. You could increase the draft by adding more height, but as your oven is mobile you'll need to make it removable.

    Suggest you keep firing to see if it's still a problem after about 10 pizza temp fires.
    Also try only minimal addition of fuel at start up.
    Kindled with zeal and fired with passion.

      Light a small fire directly under the flue to warm it up first.

        Need to get the flu hot to create the vacuum. Also our oven when we were seasoning it was (wet) smoky. But its definately drawing great now. Our flu though is substantially wider.


        When starting a fire in a seasoned oven do the majority of you create a "rager" in there. I notice that with the fires we are building we don't burn off all the soot in the dome. We definately burn it off in the center where we start the fire and to whatever side we push the coals to, but there is portion of the oven that still has black soot on the ceiling. Is this good/normal?
