I guess I made it sound like I was cleaning up threads with the fine abrasive, but no, what I'm talking about is different. I'm talking about what should be a smooth inner surface of the fixed and adjustable cups. this is the part the secures the sealed bearings. I didn't like the corroded in one fixed position condition. I want to be able to put some quality grease on all the parts when I reassemble the thing and have it go together slick without any binding so that I know I have done a quality install. I think tomorrow morning I will take a picture to illustrate what I'm talking about.
Taking abrasives to the threads would maybe smooth off the burrs and the high spots, but would make a mess of all the nooks and crannies.
