    G’day
    Brick in Oz has a link to all manner of brickwork and buttressing.

    Steve’s build has quite a discussion on buttressing which influenced me to buttress mine as my entrance is quite deep.

      You do not need to buttress a full arch An arch with vertical side walls "and" a heavy chimney (ie brick, rock, etc) or ovens with full soldier courses are candidates for buttressing. I do not see a need to buttress yours.

        The internal brick shell of my oven is pretty much isolated from the outside world and pretty much apart from heating/cooling only has to deal with gravity. The outer arch entrance on this oven is planned to be insulated from the oven entrance brick by high temp rope insulation. So it’s basically a single skinned structure. The loads aren’t going to be static. The stainless steel chimney is like a big lever and open to the next force that comes along ie. children.
        You build them they will climb them. Mines always been a kid magnet and still is. The kids next door have already snuck over and climbed mine!
        So if it’s external double skinned I say.

          Thanks Guys,

          A bit of progress to show, outer arch complete.

          Vent is now 15.7 " x 6.5 " (400 x 165). Hope its not too big.

          Outer arch top keystones worked out well, meant i didnt have to add another brick here to initiate level.

          Is it ok to start curing this oven , given the amount of rain were likely to see ? It is under cover, but the humidity is thru the roof. Was thinking heat beads, wood is too wet anyway. I have no vermicrete to contend with, so only moisture held in the bricks..

            Will be putting the FB blanket directly over the IFB's tomorrow, and then some fine aviary wire over that to hold it and the render in place. I think the smaller gauge wire was preferred over chook wire ?

            I have searched but cannot find the ratio/mix for the 1st/2nd/3rd coats of render/stucco, or is this store bought ? If so, what type ?

            Thanks

              With cyclone looming overhead, managed to get blanket and mesh screwed to IFB's.

              Some progress on the vent. Will no doubt have cracks where Ive fixed the outer arch to the inner (10 -2 oclock). RemInder of the outer arch is floating,

              Stuck a spotlight inside the dome, to prevent additional moisture ingress. I fear its way too wet to start curing.

                Did the cyclone hit your area, everyone ok?
                Cheers,

                Steady

                  Cyclone was a fizzer Steady.

                  The spotlight idea was excellent - got to around 60 deg c.

                  2 weeks of that, and its time to slowly ramp up the curing.
                  5 x heatbeads are in.
