Hi Tom,
The flat probably isn’t necessary when machining a sphere. Although it does help prevent center drill deflection if it’s a little off center. I do this out of habit as it’s very useful for drilling a length round stock to prevent the oblong center hole that occurs when drilling into the curved surface of a cylinder.
Looking at your pic. I’m not sure what you will be drilling. Is the end with the brass rod running through it the ball you will drill?
Bob
