Dave,
As a former machinist, your work looks great. Today a cnc mill would make things easier. In the older days, it was a matter of skill to hand crank a mill to get even cuts that would create the optical reflections you are getting. The cutter had to be sharp and fed at the right speed on a solid machine. Sometimes you have to put drag on the axis to get past chatter. This is a good example of old skills meeting a modern application. Way to go!
