Brickguy, it's not where they are located, its the angle thats created. To make it simple, draw a line from your pin to the CG, put a dot 1/2 way down the line. From the dot to the pin is the hour, dot to CG is the minute.
A simple 1:30 RH drilling would have the pin by the ring finger, the CG in the center of the grip.
