First BJD scale ring

This is my first BJD scale ring. It is made from sterling silver. It looks awful, which is good, because the next ring can only look better!

I lost count on how many times the cutting bur rolled over the ring out of control. I learned that;

1. I have no skill with flex shaft tool and burs.
2. Round nose pliers are no substitute for a ring mandrel.
3. I should have a plan before I start cutting with burs.

ID= 0.228" (5.8mm), OD= 0.295"(7.5mm)
