Sorry for the metal content, but there might be someone here who knows
the answer!
I would like to find the center of a 6" metal disk (center the mill
spindle precisely over it).
Here is my plan...
Use an edge finder and find 3 points at roughly 45 degrees to the
center by moving only the X axis, then only the Y axis (forming
a right triangle) with the hypoteneuse over the disk. Go halfway on
both X and Y between those pairs of X and Y numbers.
Does this sound like a reasonable plan?

That plus the milltable and an edge finder will do the job.
