My son was just promoted to SSgt. (USAF) My idea was to use my CNC router and VCarve Pro to engrave his name and new rank into a pen blank and and then turn it on my lathe.(The idea sounded good in my head - in practical use not so much) The blank is 3/4 X 3/4 X 2.(bottom half) I need the engraving to go deep enough so that when I turn it down to the guides I still have engraving left over. I played around with the ides but my engraving isn't going deep enough and my letters are too small. Maybe this won't work but has anybody else tried/done this? I could use some help. Ideas?
