Here is my shot at it, tool is restricted to given dimensions to clear shaft, cutting diameter must be smaller than contour diameter and width needs to be proportionally in sink with shaft or you will have heavy chatter as a result of wide cut and week shaft.

I took a cut from outside first instead of leaving negative stock to penetrate through outer edge of wall, it also provides way to evacuate chips when doing inside section.
