flywheel resurfacing....
So I've got an ap1 flywheel which has about 70 k on it that my friend said could be resurfaced for my next clutch job so I don't have to tear the car down take the flywheel to the shop and then put it back together another day. The flywheel was resurfaced after 50k and has been pulled for a big turbo overhaul after 20k was put onto it.... Its got a little surface rust but nothing deep or terrible...
The flywheel in my car was bought new 20k ago and can definitly be resurfaced but time is the only thing that's holding me back from using that.... Would it be alright to use the other flywheel after resurfacing it...or should I use my current flywheel and have it done.
Main question... How many times can a flywheel be machined before its worthless?

The factory service manual does not give a service limit for the thickness of the flywheel, just one for axial runout (which is 0.15 mm). They actually say "If the runout is more than the service limit, replace the flywheel and recheck the runout. Resurfacing the flywheel is not recommended." You could check the runout of the flywheel you have to see if its still good without a resurfacing. However, with only 20k on it I would imagine your current flywheel is perfectly fine to keep in there without resurfacing.

I put in an ACT flywheel with low mileage on it, we just cleaned it up with a bit of steel wool and it has worked fine. I think it had about 20k miles on it.

Your current flywheel will be nice and smooth right now; I wouldn't mess with it at all. If you do end up using the other flywheel that has some surface rust instead, then yeah you can try to wipe some of that off with steel wool or something.

I have resurfaced well over 30 S2000 flywheels with no ill effects. The key is that it is a stepped flywheel and so not only the friction surface, but also the outer rim needs to be machined as well to make sure the Pressure Plate is clamping on the disc properly. I have yet to have a failure out of a machined flywheel or have any issues with getting proper adjustment out of the CMC. There is more than enough meat on the S2000 flywheel to machine a couple of times. YRMV

Honda does not recommend that the flywheel be resurfaced.
Just scuff it up a little with crocus cloth or steel wool in a circular pattern and you'll be good to go.
