I use a method that works better than using a edge finder to locate a hole in the center of a piece of metal. Just requires a caliper and a 0,5 MM Pentel P205 pencil.
A sharp line from a point or an Exacto knife is better.
1. Mark two lines on the X axis slightly off center.
2. Do the same for the Y axis.
3. Peen a hole in the center using a 5X or greater lens. I work the peen so the circle is centered in the bullseye.
4. Now in the drilling position. Use a pointed shaft and locate the hole with a 5x lens.
5. Now chuck up the center drill and make a light cut.
6. Do any final X-Y movements/center drill cuts until perfect alignment.
I have my flame retardant suit ready.
