    Well the Xmas period has been productive, have managed to complete courses 9 & 10 & plug the dome, what a great feeling!
    Had some problems removing my wooden brick and chipped a couple of floor bricks, luckily I was able to lift and turn these over.
    At this stage I am quite pleased and eager to push on but in reality, maybe I should hurry up and slow down?
    I don’t know if I should attempt the chimney or the insulation next?
    Cheers

      Nice looking work! I built my chimney before I insulated. It might be easier working without the chimney and vent arches, but if they are there it will give you a good reference point as to where and how to trim the insulation around the arch. I ended up butting the insulation right up against the rear of the chimney. Click image for larger version

        I'd consider working on your chimney and letting that dome dry out awhile. Insulation will slow down that process considerably.

          Thanks guys, I think I will take your advise.
          Unfortunately during this festive time, there are several days when I am told it is “In-advisable” to fire up the power tools.
          Is that a sign that I am getting obsessed with my WFO?
          I have run out of fire bricks and only have enough for the landing, I do have have lots of very old Red Pressed bricks from an old fence that i intend to use for the entrance and chimney.
          Do you think there is any issue with that?
          I am going to see if I can get a 200mm/8inch chimney today and work out the transition.

          ​​​​​​​Cheers

            You may get differing opinions, but I think you would do better to use firebricks for the throat/smoke chamber (chimney entrance area), where the heat is more intense, whereas the heat is not that high on the landing. On the landing, you could use the others. You can use those for the chimney, also. The regular firebricks should be saved for where the heat will be more intense, as a rule.

              Thanks Carl,
              Yes I wondered about the hot entrance from the dome exit to the flue transition, is this what you call the smoke throat chamber?
              I was thinking about maybe using the red bricks for the sides of the landing / chimney support area?
              I might cut them and see what they look like?
              Cheers

                Yes. If you keep that in mind, you'll do fine. Where the intense heat will be, try and use the firebricks. That area is commonly referred to as either the smoke chamber, throat or flue transition, but for the most part, at least w/an oven, it's all the same. If you get away from where the intense heat will be, your reds will do fine. Cheers

                  G’day
                  would you settle for ten years? Well I just realised mine is 10 years old now and that’s entrance and chimney that’s made of commons. Recon your good to go and the plus is commons are water resistant unlike firebrick!

                    Thanks Dave,
                    I have been mucking round not sure which way to go, obviously overthinking it again!
                    Anyway I have made up a new arch template and cut the lower few courses for the landing area out of red pressed commons.
                    Does this look like I’m on the right track?
                    Can I just bevel off the landing brick at 45 degrees where it meets the oven floor and fill it with insulation blanket as a heat break? I don’t have any stainless tube handy.
                    I need to find a stainless 8” flue

                      I need to find an 8” stainless flue, not easy this time of year.
                      I think that is the correct size for my 39” oven?

                          Well, finding a Flue is a bigger issue than I thought!
                          I think I need an 8 inch or 200mm diameter, and I thought just single skin would be fine?
                          But then thought that if it was exposed to where someone could touch it, which it is, then it would need protection.
                          Would that mean it would need to be double or triple skin, or would it just need to be guarded, maybe with a perforated tube over the top?
                          Are there any thoughts on this?
                          Are there any builders in South East Qld who have sourced a flue similar to what I need?
                          Or, are there other alternates?
                          A 39” or 200mm dome may be on the verge between a 6” or 8” Flue?
                          6” flues are very common, but would I be making a serious compromise if I use one?
                          As my build is external and I don’t intend to cover it, I had thought it would be stainless steel, but most commercially available Flue Extensions are Stainless centre with Galvanised skins, which I still think would be unsuitable?

                          All thoughts very welcome.

                          Cheers

                            G’day
                            Why a flue?
                            Youve a practiced bricklayer.... well why not a brick chimney.
                            Get a chimney about your head .. and go wide.
                            No smoke stains.

                              Pushed on and started the landing.
                              Just used some ceramic rope to make a Thermal Break, I think it will do.

                                Good to see some thermal breaks. It's an often overlooked feature of oven building. Will you use one on the landing/floor also?
