Thanks guys, that's the kind of input I am looking for. 
The angle of the taper is 63.43° (2:1) and may need to be steeper. The taper will also require a very smooth surface finish. If I make the whole gauge taller, then the taper could be steeper. I wanted to keep the gauge short because my round column mill only has 5" of z-axis travel and no knee.
When I get the time I will set up an experiment to see if I can determine what a reasonable "angle of attack" is for this indicator style. I really appreciate the feedback.
