@Nusbacher @AspiringLuddite Thanks. The bezels were marked and centre punched for the three holes. Drilled, then hand cut with metal shears. Hand filed into the disc shape. I made a die and used a rounded punch to get the centre of the bezel to pout deeply enough to house the stone. Then a larger die and punch to get the final conical shape. I cut the quarter detailing with a small triangular needle file. Fixing the bezel with rivets holds the stone.The fleus de lys were a real time hog on this.
Medievalists and Medieval-adjacent. Sort-of.
