Hi Builders, I made some progress again!
I realized when trying to build the bricks over the arch, that my arch stones were not long enough right on top of the arch. I could have proceeded, but I decided I had to reconstruct part of the arch, to have a better support in that area. So I had to go backwards a bit. I broke down part of the arch and made effort to cut some new arch stones. After that I could proceed with the next courses. And now I managed to close up the whole dome.
Next up is starting on the flue gallery. I already 3d printed a mold to cast the plug (probably cast it from a mix of plaster and vermiculite, or some other breakaway plaster mixture). I build a gallery entry template, and everything comes together. I do have some thinking headache on how to proceed. I have a flue pipe lying around of 120mm, but I actually should have a pipe of 125mm (I know the difference is small). But I am also considering going for a twin walled flue pipe, that makes the whole construction proces more complicated).
