I took it off a friends SR-60. I used some fine tipped tweazers and a Exacto-Blade. Heat up the outer cup with hot water or a blow dryer and lightly pry it up. Be gentle as is may break if you apply too much force. I don't know if this works on newer models though.
I don't have money for any sort of milling to be done, but I'd post something on Craigslist as my first bet if I wanted to do that sort of thing. If I pick up another pair of cups somewhere, though, I might bronze them or something.
