�Seems like measuring this larger diameter

Ideas with how to proceed would be greatly appreciated.

Start by setting the compound rest very accurately. Then cut the
chamfer deeper than needed. Determine with the Z axis feed the
distance you cut the chamfer. Trim the oversize from the face of the
piece you are cutting. Then the chamfer that you cut was precisely
done and you have the dimensions. Or mesaure the dimensions with a
dial indicator and do some math.

I would probably do the latter.
