    Re: John's 42inch Aussie WFO

    I have a question around the chimney landing. I will be building the front bricks out of a purple coloured brick (as per the oven base) but there will be no way to tie in the landing Chimney bricks with the arch bricks. Will this be an issue??? I will source some brick ties to mortar in for stability but am hoping for some direction.
    I'm afraid I don't understand the question - perhaps you could give us a sketch to clarify what you're asking?

      Hi Dmun,

      I was not very clear with my question. As per the below diagram as I will not be using fire brick for the landing bricks so will need to butt my landing bricks to my oven brick arch (hope this makes sense).

      I was concerned that this might be an issue down the track

        Ok, Now I understand. There is no problem having dissimilar bricks in that place, in fact it's a notorious cracking area because of the temperature differential between the hot dome and the cooler entry. If you are concerned, you could engineer a slip plane between the two dissimilar materials, they make a special refractory paper for just that purpose, or you could just ignore any cracks that develop, like the rest of us.

          You could also leave a 10mm gap and fill it with perl or vermicrete

            I think with mortar and ties you'll be fine

              Much appreciated guys.

              Now I don't feel as bad. In that case I will just use some brick ties and unfortunately expect some cracking in the mortar

              Cheers

                  If it does crack,
                  it'll get covered with soot anyway

                  out of sight... out of mind!

                    lol you sure Mark, Google Earth is a pretty powerfully tool you know

                    Mitchamus I agree the soot will probable cover most of the imperfections any way

                    cheers

                      Began work on the chimney landing bricks today. Things went well and layed 3 courses. I utilsed brick ties to to reduce any cracking as those bricks do not overlap.

                      I also cut out 1 of 2 templates for my brick arch supports so I will have a busy couple of days in front of me

                      Cheers

                        It's looking really good. I see one potential concern that I'm a little hesitant to point out because you probably already know this. It looks like the wood in the 4th picture is a pattern for your arch. When you make your arch form, make sure it is short enough to shim underneath the form. After building the arch you might not get the form out without damaging the arch if you don't have shims you can take out first.

                              Hi Jim

                              You have a great eye their. The template was used to give me the overall height of the 3 arch bricks. I hadn't thought that far ahead but will definitely take your advice and shim it up once cut to size.

                                Thanks Mitchamus

                                That was the easy bit!!

                                I guarantee the arch work won't be as clean!!

                                cheers
