    Do we have data for this? I am not disputing it, just never seen the data. I am pretty thick with the blanket and added another 3 + inches of vermiculite. After all that, some seem to hold temp longer than me and I don't understand why ( the Pompeii build).

      I'm basing that on using my IR thermometer on my oven when it was going great guns. 900 inside, same as the air temp outside. I have about 4" of insulation and I was trying to figure out if the vermiculite was worth it. I figured there wasn't much point if the outside of the oven was 60 degrees.

        I figured to cover my oven it would take 7 bags at $24/bag. A little more than the $50 you mentioned that's why I brought this up Seems like the consensus is about 50/50 ?

        Pics of last nights work. Next ring hopefully goes in tonight.

        I put a little firebrick wedge under that back side of each brick. I knew I saved those for a reason:

          Looking Good......glad to see no hammering was done..........My advice turned out to be a bugger for me. Hope I did'nt steer anyone down the road of no return.
          My apologizes

            Ok so I'm getting ready to put on my last entry brick that will have a groove cut in it to rest my arch bricks. I also had to make a "funky" cut to one of the brick for the ring I'm on so I can gradually bring that ring up against my inner arch. Pics are below. My only concern is it cracking and falling off (kind of thin) and it getting in the way of taking food in and out. What do you all think?

              I think you did a fine, precise cut that will give you a headache in the long run. But, chances are that it will crack and break off at the 90*, which won't effect anything.

                Much like ken's build I was planning on resting my next layer brick on this "edge" which would be probably twice as wide, then the next on top of that until I'm back to full bricks. If that comes off then I'm losing my support .... the whole reason I did it... :/

                  the pressure is outward not straight down, and that little piece breaking off won't cause the upper chains to fail

                    I'm planning on a 1" lip around the outside of my inner arch for my oven door to seal up against on my vertical walls. I'm thinking of making the lip on my arch only 1/2". From experience do you guys think 1/2" is to small of a lip?

                      In principle a 1/2" reveal would work fine, in that your door should seal plenty well with 1/2" of contact. However, I'd think that would make fabricating the door trickier--you don't have a lot of room for error if you cut the outer part of the door too large, too small etc. On the other hand, your build so far shows you're capable of a lot more precise work than I am, so that may not be an issue!

                          Ok, I know I'm a ways away but I'm always thinking ahead. My question is concerning the door for my oven. I had thought that the door should sit in front of the oven arch up against the 1/2" or 1" lip I had left. It has been brought to my attention that the insulated door needs to sit in the arch way and have some metal on the back side that sits up against the lip. Is this right? I attached a photo of what I think I'm supposed to do. I was going to use the extra ceramic fiber board and wrap it in stainless steel (weld it) almost like a sandwich. The piece of stainless steel facing the outside of the oven would be larger by 1/2" to seal the oven. The thickness of the metal would be 1/8" I believe.


                          This view would be if you were looking at the door from the inside of the oven:

                            I made my reveal about 1 inch - see attached.

                            I am at about the same stage as you are at so I will be following the rest of your build closely!

                                That looks good so far. I have my entry dimensions set, I'm wondering about the removable door itself.
