Great to see you have been able to make some good progress with all that rain....it seems to be getting better now (about time).
Most Pompeii ovens will go slightly oval in shape to make the arch/dome transition work......mine always do. There is a way of getting the dome to be perfectly round but it involves a complicated inner arch. By going slightly tear shaped won't affect the strength nor the performance of your oven.

Got a free afternoon this weekend to make some more progress, feels like quite a while since last worked on the oven. Almost completed another ring although with these higher rings the cuts are getting a bit difficult, about four of the bricks project out on one side where they meet the lower ring - I am considering replacing them but equally keen to get finished! Also took delivery of some more materials - thermalite blocks and timber for the roof, probably getting slightly ahead of myself! blockwork to back ad sides then brickwork to the front to take in the curved hearth slab including another arch over the outer arch. Have also started mocking up the entrance/chimney area, planning on fixing a flue on top which will run through a projecting roof over the front of the front of the oven. Will it help if I try to make as large a entrance to the flue or will the smoke run straight over initially anyway (hope that makes sense?) I am building the chimney enclosure about 10-20mm away from the oven to take in the vertical tolerance (errors!) on the inner ring/arch - once complete what would be the best material to fill this gap? I was also going to mortar the entrance landing floor and wall together using the high heat mortar which I haven't been able to use so far! Are there any issues with that? Thermal expansion etc? Once all that is done I need to deck half the garden to bring up the levels correctly otherwise will need stilts to use the oven! Hope to get the dome and chimney finished no later than end of April which would leave me about three weeks to dry out the dome in time for the planned pizza party - does that sound realistic?

Any comments appreciated!

Made some more progress in the sun last weekend, got quite a bit done in the short time (I was allowed!) although did have to take down a small section I rushed. Made a schoolboy error by trying to work on the chimney as well as the dome, had to spend a while carefully removing the form so I could access the dome. Got my wifes pregnancy ball out ready for the easter weekend, hopefully finish it then! The chimney is giving me a few issues, trying to decide whether to go for brick chimney or duravent and how to go through the roof ridge as looking to have a 1m overhang. Would the chimney arch, one brick thick, support a full brick chimney?

I think you would have to buttress the arch to ensure it didn't splay out with the weight of a full brick chimney but I'm only guessing as I'm not a builder and can only go on personal experience of my arch collapsing the first time I built it !!

Finally finished the dome and most of the arch, been a long process, thanks to those who gave me advise etc along the way!
Couldn't resist having an initial fire just to see how it works, got a little over excited!
Bo, thanks for the tip, think I will go for a duravent chimney to make life easier.
Just need to dry all out for pizza party on the 18th May.
Last brick of the arch finished the diamond on the angle grinders, the builders sand and the fire clay so worked out fairly well...
