How are folks creating the design for the arched dome. I am considering a 30 inch diameter oven to keep it on the smaller side. If I go with the High Vault of 19 inches, it looks like I need to keep my first row of bricks standinf on end and then I need to place another flat on top to get me to 11.5 inches before I start the dome part curing inwards.

What I dad on CAD was draw a line 15 inches wide (Line A). Place a line 4.5 inches on the left side of Line A called Line B. Place another line on right side of Line A 19 inches high called Line C. If I now draw a circle at the intersection of Line A and C with a radius of 19 inches. The circle never meets Line B. I need to extend Line B to 11.5 inches.

Hope this makes sense. I read somewhere in this forum a reference to DMUN and his approach but could not find it.

Thanks for any help.
