Thanks.

That makes things easier, and the 9/64" bit is more stable.  Looks like I
probably grabbed the numbers on that from an old version.

Yeah.  At the complexity of the inside you have there, I don't see

inside corners are hard, but it looks like a single cutter pass can
probably run past far enough to work if that direction were taken.
