Need suggestions for tightening polished/chrome stock rear rotor rivets

[Chilly Rock]

After a routine inspection of my bike yesterday, I noticed the rivets on the rear rotor is loose. LiquidPain polished my stock rotors about 3 or 4 weeks ago and he did an awesome job with chrome-like finish. I did a search and found fixes for tightening rivets by using a ball peen hammer and another using ball bearings with clamps but I don't want to scuff and scratch the rivets and cause imperfections then I will probably need to get it repolished. Any suggestions for tightening the rivets without scuffing or damaging the chrome-like finish of the rotors?

Try two ball bearings about .75 of an inch, put one on each side and put them in a vice, that way your not teeing off with a hammer and end up hitting the rotor.

Or,

replace it with the superceding part number (you might get it under warranty since it's a known safety issue) and THEN have Liquid Pain re-polish it for you.

I thought about that option if I could find a good price for one. I may give a try with the ball bearing method and put blue masking tape on the rotor while working on it. I might be able to get it done without damage, if not I'll send back to LiquidPain for a 2nd polishing.

Since it is already polished I would not be afraid to squeeze the rivets
between bal bearings ,..'' clean ball bearings '' , and make sure if the look of the rivet changes,
to make all rivets look the same , then get a buffing tip ( cotton wheels ) to put on the end of a drill ,
using buffing compound from auto part store get the shine back to where it was.

Remember to squeeze the ball bearings slowly and alternate like tightening lugs on a wheel. I little goes a long ways. Just take your time.

We just did PWRTRP's rotor. Used 2 ball bearings, but we found the vice was not enough. Started to hit ball beartings on the concrete floor, but found that was not enough. Used a 2.5lb hammer and found that did the job. No movement out of the rotor now. Also, note, his rotor had rotational movement only, no side to side play.
