In the end I did the whole think using a brazed carbide AR bit. I had
some issues with holding the 1/2" boring bars Jim W. suggested so I
thought I would stick with familiar implements.

The diameter is spot on 5.401" - a slip fit for a 5.400" face ring.

I shall try turning the ring in this contraption within the next few
days. When I have decided whether to go with superglue or double-sided
sticky tape :-)

Just make sure you pick something that stays stuck when it gets warm.
