Last course done! The last 2 courses were laid freehand as my indispensible tool became useless at that angle.
I will cap this 6.5" inner diameter opening with 3 large pieces, adding no additional height to the dome.
My other option was to lay another tight course and drop a keystone but I decided not to do that as that would have added another 1/2" to the dome height which I don't want. Besides, I didn't want to spend another few hours tapering each tiny piece, piece by piece to make them fit.
I need to now think about how I'm going to design the vent area. I need to make it as wide and as deep as possible. I don't want a smokey environment there as that corner is in a nook and not in an open area, and next to a door leading into the kitchen.
I will need lots of napkins for this. Back to the coffee shop....
Oh my lord! I have missed a lot of your build. Great job on the oven, George! All that research paid off and resulted in a record build. Amazing brick work. Very clean and precise. What can I say but get on that vent ASAP so you can start cooking =D
Your oven looks to be up against an exterior wall of your house. Am I correct? How high will the chimney have to go to clear the roof?
Hi, the outer opening will be rectangular as well, but will also follow the curvature of the hearth. But I'm not sure yet exactly how I'll 'form' this curvature.....most likely a combination of an angle iron and a flat iron/or rebars bent into shape and welded together. This will also serve as support for the vent.

I was thinking cutting triangular notches in strategic points on the angle iron. Bend the angle iron on those strategic points til you close the notches and weld them into place. I hope I'm describing it clearly if not I'll try to draw something up

Thanks Raffy, I envisioned doing that as well. I think it's the best method.
I started work on the vent landing area today. I used several insulating bricks to create a thermal break, then poured concrete up to the break. I did not build this up to floor level as I don't yet know what finish material to use for the landing. To keep uniformity, I might 'tile' the landing with sliced firebricks. Same goes for the inner facing vertical insulating bricks. I will use refractory cement to bond the firebricks.
Wow George, what coffee shop do you do all your thinking at? I need some of that java-caffeine for my brain!
Nicely done with that thermal break and concrete pour. Are you thinking of placing some sort of solid surface, flush with the landing? I guess with that thermal break you could do just about anything for a counter/front landing.
