I'm not planning on using a milling machine. I have a
radial arm saw where the yolk rotates 90 degrees,
placing the arbow on the bottom. I've already used it
and can easily cut through all eight supports in a
single pass. The problem is with my ball cutter. While
it is has a spherical cutting head, it can't cut
deeper than halfway down.

Dr. Resonance told me where to get what I need.

Thanks.
