    I've been back at it but haven't posted in awhile... Quick question.. I plan to cast a concrete chimney cap... Is regular concrete accepatable for this or would I be better off finding a large piece of stone? Or could I cast with some variety of reinforced homebrew? I am hoping it will be as simple as one flat piece that overhangs the chimney about 2" in every direction, supported by a square brick in each corner. Between the corner bricks I will stretch some spark arresting mesh before I place the piece that I will be casting on top.

Then I just took a small piece of scrap rebar and a hammer and knocked them out from below. I only have two weep holes but I wish I would have done a few more. I've never actually seen anything drain out of them, but it's nice to know they're there.
    Thanks for the tip. I forgot about that method in your build. My only reason for going with a drill was to avoid having to screed and trowel around pipe stubs. I like the idea, and will have to copy it.

    If i can source it, i'll use 2" foamglass, and calsil on top. I've been debating the tiles as well, but agree it's cheap insurance. I'll probably go ahead and do it.

    Have you started yet? I would highly recommend weep holes in the hearth and a layer of foam glass under your cal sil board (if that's how you will insulate your floor). The foam glass won't let moisture get up into the cal sil board. I also put a layer of loose tiles between the hearth and the foam glass... I am not sure if that was necessary, but it was a very cheap way to get more space between my cal sil and the concrete hearth.

    I am just not sure how I would cut the marble to contour around the dome

    I poured countertops in my utility (bar/laundry) area and had excellent results with the forms and admix from
    https://www.concretecountertopsolutions.com/


    You can use white concrete and acid stain, but the result is not going to be "marble" If that is what you really want then an epoxy coating is what you need. There are plenty out there, one advertised almost nonstop on youtube. Here is another https://www.countertopepoxy.com/prem...ountertop-kit/

    Lastly - If you check out Buddy Rhodes website - you may find some inspiration for something unique as well.

    Haven't posted in awhile.. coming out of hibernation...

    We've been using the oven so much that progress has slowed. I haven't done much work on the actual oven in quite awhile, but have done some work to the area around the oven. Still needing to finish bricking the chimney, pour the final countertop and stucco the base.

    I would like to pour a concrete countertop to look like white marble. Has anyone done this successfully? Any recommended concrete mix for countertops that you can roll pizza dough out on, cut on, place hot objects on, etc?

    Seth,

    Great looking bird! I admire y'all that cook turkeys with open coals. I've been a little skeered to try it, though I have done chicken that way. Actually, I don't do turkey. But, I love seeing those cooks that do. I'm going to have to break down and try it some time

    .....My wife thought it was strange that we never even turned on the conventional oven once for our Thanksgiving meal......
    These ovens are great at taking a load off the power bill and also helping the ac to keep up. We've used ours when there was no power on the grid!

    Wood fired Thanksgiving! My wife thought it was strange that we never even turned on the conventional oven once for our Thanksgiving meal. Though we did use the stove top for potatoes and gravy.

    Had great weather this weekend, stayed above 42 overnight Saturday so I was able to get my last coat of stucco on and started to turn the corner on my chimney bricks... And of course we had more pizza..

    Yeah, I think I will drape some plastic over the front face this winter, and hopefully before next winter I will have my roof built

    Made about 30 pies yesterday evening. My wife made scones this morning and I've got some bread going right now. It's incredible what you can do with just one fire.

    It's also pretty awesome that while the inside of the oven walls are over 1000 F, the outside stucco layer is cool to the touch.
