    You can do a sand and fire clay mix as well with a notched trowel to help you extended your fireclay

      You should be able to just screed the mix to fill the low spots. The fine cracks in the board are no problem.

        So after a full day of work, I got the insulation board down and all but 8 pieces down for my oven floor and first course for my wall.

        Question... My first course for my wall does fit pretty tight. Can I dry stack my first layer or do I want some mortar between the bricks?

          Leave it be - looks good.

            Ok since Les said to "leave it be" I figured this would be a good time to experiment with the mortar and working the brick since I really can't screw anything up since it's good to start with. I quickly found out that planning an oven with all 1/8" joints won't happen. Makes me smile when I remember reading a thread where someone wanted to build one with no gaps at all. I'm now going to plan on 1/4" joints all the way around. Hopefully I'm still leaving myself enough "wiggle" room.

              It can be done. The front to back taper would require a 14 inch saw to make a reasonable attempt. My next oven

                Strive for the best joints you can on the inside of the dome, mortar is your friend on the outside. I strived for as tight of inside and outside joints I could get. If I were to do again I would just focus on the inside and spend my energies elsewhere.

                    Ok so my opening is 19" wide, 10" high on the ends and 11 1/2" at the center. Any ideas on making the form for my arch?

                    Also I printed out my oven opening on paper and it looks huge with those dimensions. Must be an optical illusion right.... Those dimensions are from FB ... mostly. The oven openings just look smaller in all the photos I've seen.

                      Whatever you decide to use for your form, make sure you can remove it without destroying it, you can use it later as a template for you oven door.

                        My door needs to be larger than that to make my seal right....

                          You want the door to also go into the opening as well as have a lip beyond it for maximum seal.

                            Also the part that goes into the opening should be filled with some type of. Insulating material, people have used ceramic board, blanket, and vermicrete perlite. Etc...

                              Ok guys so I got some more work done on my oven over the weekend. I had all of my bricks precut and as I moved along some of the bricks would fit perfectly without any mortar. I placed them with no mortar and kept moving around my dome with the next brick and so on. Is this ok to do?.... No mortar on some bricks?

                                Yes, many kilns are built with no mortar, but I think you should mortar the entry bricks well.
