    Re: K79 Oven Build

    Even if you do run into the tear drop its okay. The oven will still function just fine. If you run into the drop all you have to do is add a key stone to avoid it, then start a new chain of bricks it will solve the problem. Ask me how i know.

    Ken's oven has been working for years so it obviously isn't that big of a deal. Try and avoid the notorious "droop" You will be fighting to get back to a true circle as you go vertical.

    K79,

    I am not sure where you are at on your arch but a tapered arch would help with a smooth transition from the dome to the arch. Here is a link showing how this done on a arch similar to yours. Hope this helps

    Correct, in my case i didn't use water, just dry sand and fireclay.

    I got my support for my inner arch complete today on my lunch break. It went faster than I thought. My plan is to put some 2x4's under it with some cedar wedges on both sides to lift to the correct elevation. Once my arch is nice and solid, just slip the cedar shingles out and done

    I covered my dome after working on it to keep some moisture in the mortar so the mortar doesn't dry too fast, however you must give it some air to breath also, don't completely cover it. After 1-2 days i would remove the tarp. Basically after the mortar hardens i would remove the tarp.

    You're lucky to have a metal worker friend. But Stainless also costs about 5x as much for the metal
    He quoted me $150 to make the door. I thought that sounded reasonable.

    It's aluminum - filled w/ loose vermiculite. I think it would help if it went into the oven a bit but I can still cook on the third day - not many are doing better than that with our type of oven. Most of the heat loss is going to be under and around the dome - insulate that well and you will be golden.
