  • Can you review my 42 inch oven design please

    Hi everyone. I have attached 2 photos of my intended design Iím looking for some feedback or anything I should look out for. Iíve read a few posts and articles so far and I want to build the best oven I can. Looking forward to both negative and positive views

    I cannot really see the detail clearly from the pics. But one item that needs to be addressed, on the cross section of the dome, it appears the dome wall goes all the way to the concrete hearth. This will cause the heat from the dome to dissipate down into the concrete hearth which will act as a heat sink. The dome walls need to have insulation under the first course so the entire dome and floor are isolated from the concrete hearth. Other than that I cannot seen enough detail to comment further.

      Sorry. These should come out clearer. Thanks for the information. Will definitely extend the insulation under and around the solider course

        After seeing the latest PDFs which I can see the design dimensions clearer. The opening of the oven should be about 63-65% of the height of the dome which is about 345mm and the current design is only 300mm which puts it below the lower end of the recommended opening height. Is there a reason the first course is a soldier course?

          Have you drawn a scale side view to ensure your arch will tie into your dome properly?

            I was thinking about keeping the front entry arch down a little as Iíve read on here itíll keep any smoke from exiting out the front and force it up the flue. The reason for the 1st course being a solider (although Iíve recently read a sailor helps keep your joints aligned better can add vermiculite Crete behind) Was because I donít want to lay the walls directly on the floor so it gets you to a halt brick above floor level straight away.

                I have looked at a few posts here and drawn it. I think the best option is to use full bricks for the arch and put an angled cut on the dome side to tie the arch and dome together

                  With full soldier first course, you have to be aware of the outward pressure of the spherical dome and the the angle portion of the "full" soldier. This may require buttressing around the soldier. If you do a hemisphere without the soldier then this is not an issue. If you heart is set on a first course soldier then consider a 1/2 height soldier. otherwise look at a half header. One more option is have the first course sit on the oven floor rather than around it then you avoid the need for precise round cuts of the floor to fit inside the dome. The ratio of 63-65% is the best oven performance and the correct size vent, chimney and vent chamber config. is the best for minimizing smokes issues. I would suggest you look in the Newbie Section under Treasure Archives, this thread contains some of the best and highly documented oven builds.

                      Hi Brady, have you tried reaching the intended door arch from the front of your stand? it seems a long way back to me

                      Cheers Doug

                        Distance is comfortable to install a door from the front of the stand. Itís up pretty high so you donít have to hunch over to reach in.
