    Thanks Les.

    Tscar, I also thought about the gaps actually acting as insulation like little areas of disruption in air flow. It's just fun to think about what is actually happening and how it might differ..

      Probably not the best place to put this but I will lose it if I don't

      This is in response to having a heat break - not sure if it's going to buy anything...

      I fired up the oven tonight and the pizza was fantastic. After the fact, I shot some numbers and I was fairly surprised. I had the door on for about 45 minutes. On the inside ( numbers relate to the lines, 9:10 PM) I read 500 deg and on the outside I read 290. That's pretty huge considering the distance is only one brick thickness plus the door. The door is on and I will measure it again in the morning. This may confirm what I had suspected in the fact that fire brick is a shitty conductor of heat.

      8:30 AM - 428 inside, 223 outside
      9:00 PM - 348 inside, 195 outside (this is after I just cooked a chicken and a few potatoes)
      8:50 AM - 298 inside, 165 outside

I have never posted a pic of something from the WFO - here is the first. 9 ounce ball (learned that from the FB open house). It's a perfect size.

        Hi Les,
        I noticed the curved marks on the inside of your oven. Did you put the cut faces of the brick toward the inside? I am curious because I have a line on some used fire brick and they are a bit chipped. If I could use the cut face this would provide a much sharper interior line. I haven't started my build yet. Still collecting the materials.

          Jimney,

          Yes I did. Pretty much all the brick has the cut side in the interior. There were a few that were clean so it was just a matter of chance on what side faced in.

            Les has one of the few mortarless builds on this forum. I tried to mimic his build with his cuts and fitting and mimimal mortar but never could come close. Thank god for homebrew!

                  This may be ridiculous but, has anyone ever used wax to hold the bricks rings in place until they are complete with the keystones. That way the wax would burn off after the first couple of fires. Any thoughts? Even a hot glue in small amounts?

                    good thinking out of the box, but you would have to taper the bricks completely on all four sides. Mainly, the top and bottom of the back ends of the brick, Otherwise it would definitely collapse i think. Maybe use wedges there but you need some bonding that survives the heat.

                      Jimney,

                      That is exactly what I used - hot melt glue. The stuff was totally vaporized from the first fire. It's a slog to do but it worked for me...

                          I'm new to the forum and have just started my study on oven construction. Can you tell me where you got your chimney materials?

                            Do you have any pics of your vent construction?

                              Tracy,

                              I didn't use mortar on the inside of the dome other than tying in the arch and setting the plug. All the mortar is in the back to maintain the angle. On the higher courses I used hot melt glue to hold the brick before I sat them with the grout bag.

                              Edit - Tracy, this shows very well where the hot melt came into play

                                Bob,

                                We have a masonry yard in Reno that carries paver's, brick, etc... They also have a pretty good selection of clay liners. You should have something like that in your area. In regard to pic's of the vent - I believe I put most of them in the gallery. It's a bit of a pain to navagate but you should be able to see the process. This should get you close...
