What did you use to cut that?

i have done a few with a 400k rpm dental drill. easily done with fg diamonds. gotta be kinda very careful handling them, esp clamping in yer ball vise !!It's a start, and keep stepping up, and you'll enter into the Faberge' egg realm. It's something to think about. Has anyone ever attempted to engrave an egg shell? Never thought to ask that one before.
