    G'day
    My flues no higher than my dome but does keep the smoke from my face. My mates oven has an internal chimney which has to be blocked at some stage to stop heat loss. Those hot gases coming out of that oven mouth can take out your fringe,eyebrows and beard pretty fast.
    Of course an oven will work without an entrance/chimney, my opinion they are worth the bother to build

      Big T,

      IMHO, Take a look on how the position of the current placement of the first arch brick is going to affect the dome on higher courses. The first arch brick is currently in-set by a couple inches from the inside diameter of the dome. This could affect the shape of the dome later on. Just something to look at.

        Thanks for catching that! Given your thoughts I should move it back out of the oven and line it up with the outer edge of of the inner diameter? Easy to correct now as I've only started on my 3rd course.

          Made some progress today. Got my 2nd course done and started the 3rd. Though I will need to look at my arch brick placement, and also looking at my picture some seams are getting a little closer than I'd like. The rain came and I had to pack up but of course it stopped once I had put everything away!

            The inside of the arch should intersect the inside of the dome. Here is a pic showing the first arch brick and arch form relative to the inside of the dome. I cut off the small triangle piece to the right of the pencil line by the IT so it matched the inside of the dome. Hope this helps.

              So after I got my honey doo list done I went back outside and took the tarp off the oven and dry fitted the 3rd arch brick and checked where the IT intersects and my IT just barely misses the edge. Am I ok or should I start over with the arch support pieces?

                Build your arch form and see what you need to do at the top dead center of the arch using your IT. Most likely the arch brick will need to be longer and adjusted for the shape of the dome. If you can make if work at the TDC then the rest of the arch will work.

                  Thanks for pushing me to get that arch form built, it's much easier to visualize with something real in place! I had been putting off building the arch form as I was concerned at the difficulty but Google seems to work well I found this link which helped me visualize drawing out a segmented arch.

                  http://tic.wpengine.netdna-cdn.com/w...Segmental1.png

                  I built the form with relative ease and am happy to be passed that. I seem to worry about things that aren't overly difficult!

                  Anyways I put a few bricks at the dead center of the top of the arch and I had one that I had cut earlier for a arch support piece but cut it wrong and used my IT to match up a half brick and it was almost flush(See attachment). So given that I think that I am good to proceed.

                    This link will also help you. Here is a pic of an arch similar to yours.

                      Re: New 32" build in Saskatchewan, Canada

                      So after using my IT i was able to visualize the issues pointed out to me by Utah with my arch support placement. Fortunately the mortar is fairly new and not super hard to get off. I just started my 4th course so I removed the end bricks in each row as well and will replace them with appropriately sized bricks.

                      Lesson learned for the next oven lol

                        Sorry that I was the bearer of bad news but with building the arch form you were able to see what the potential issues were. Better now than later to make adjustments. Believe me, I had several redos during my build.

                          Meh is happens... I'm glad that you pointed it out to me I'd rather know there's an issue before its too late. Plus look on the bright side you saved me lots of grief and gained me 2 inches of space in my oven.

                            I lost a few hours today moving the arch supports but it will prove to be worth it later on in my build. I got two more courses done today with the exception of the end pieces which are waiting for me to build the arch. We had some really hot weather this afternoon and decided to leave it there and regroup when I have some time in the next few days to hopefully get the arch done.

                            On the last 2 courses I started having to really watch my seams. I didn't notice one side until it was too late but having a second set of eyes helped so I have been trimming some bricks to a smaller size to stop this from occurring.

                              The second set of eyes is handy. I am helping a friend with his build at the moment and had the thought that a mirror on a stick might be a good thing to have once the angle starts to increase.

                              It seems to take no time for the bond creep to get away.

                              Your oven is looking good.
                              Cheers ......... Steve

                                Looking good. I noticed some of your upper corners not meeting. If you make that point correct, and the diagonal lower one, the brick will be in the correct position every time. It is not problem as is, just a tip moving ahead.
