Dome arch is complete and didn't fall over when I removed the form. The taper angles were pretty variable as I dialed in my technique, but I figured it's a good place to learn as most of it will be obstructed by the vent arch. I want to make sure ai have a well-centered keystone for the decorative arch, but I don't think its critical on the other two.
I finally started getting some droop in the dome near the top of rhe arch, so a few custom shim bricks brought things back to level for course 10. The numbers on the bricks are my reference for the bevel angle.
