To clarify: I need to cut the OD of the crown race seat on the fork. I have the proper tool and I've done the job a number of times. It's just that this is a fully chromed fork (crown race seat and all) and chrome destroys the cutter. I do not want to ruin an expensive cutter. I was hoping someone had a method to remove the chrome other than taking a file to it. I'm afraid of filing low spots on the seat.
