Powermatic 45 index plate

I have a Powermatic 45 which has radial play between the index plate and the headstock. It is only about.020 at the rim but it makes a rattling noise when the lathe runs. There is zero end play in the headstock and the rattle is the only symptom. I've had the lathe for a year and it performs flawlessly. There is excess clearance between the plate and the key in the headstock. I'm very reluctant to "fix" a problem which is so minor. Any owners out there that would care to offer suggestions?

not quite sure what you issue is but.....

If you have a sloppy loose fitting key, you can use a center punch to make dimples/raised circle along the side to increase the width slightly. That will also work between two flat plates instead of using shims. Only dimple one of the plate, the softer material preferrably.

The answer to your question will only be as detailed and specific as the question is detailed and specific. Good questions also include a sketch or a photo that illustrates your issue. (:< D)

Ron try and get in touch with this guy, he might be able to help. He is restoring a lathe like yours. I think if you join this forum you will be able to send him a PM.
