How many times can a flywheel be re surfaced?

the OE flywheel was previously resurfaced approx 10 years ago after 100K daily drive use when the 83 D150 was taken down to the frame for restoration.
Fast forward to today, 50,000 miles later, I am changing the clutch out, the pressure plate failed, got into hard shifting found over .260 difference from high to low on the clutch plate fingers.
I don't see any scoring on the flywheel but there is wear that I can feel at the outer edge where the clutch disk runs.
This is a slant six vehicle so replacement flywheels are not readily available.
I measured the thickness of the flywheel and it is .858 thick and uniform in the three places that I measured.
Can it be cut again?
