Ok.. so I think I've discovered how it is done... The only thing I'm not sure is whether it is possible or not on a Haas VF-2.
Use an engraving bit 30 degree with a 0.001" tip
The total diameter of the dial is 3/4".. So the indicating lines are 0.006" apart with a 0.002" line width.. does this seem feasible and particularly on a vf-2?
