David,
I've had good luck engraving small letters using shop made spring loaded
pointed tool and not rotating it - Sort of like the pantograph engravers
they use in trophy shops except with a CNC control instead of following a
template - Easy to make multiple passes with CNC to make the letters deeper
- You can make quite small engraving and still be very legible presuming A)
- NO backlash in CNC system & B) - NO slop in the spring loaded engraving
tool - The spring loading removes the restriction on absolute flatness
required with solid tools used to engrave small characters -
