Thanks for the picture of the dial indicator, I am around one several days a week in a friend's shop that makes custom pool cues.

 

Well, got back from the dealer after they put the centric spacer/adapters on the hubs. VIBRATION GONE. The spacers are some kind of hard plastic plastic like G10, FR4 or FR5. I know it's hard for some people to believe, it was hard for me to believe but the fact is the centric hub spacers worked.
