[just plain bill]

I agree with Jim, if it is probably a few tenths I would just polish it off. The emery cloth will just follow the surface and remove material evenly. This would be in a lathe or some other device to rotate the part. I would start with 180 and finish with 320 or finer. It sounds like some want to over engineer a simple operation. If you are measuring a couple a thou over then grinding would be the best. I would grind it with my toolpost grinder if it needed that much.
