As far as the ring issue...ain't that funny....there not suposed to move....I am sure the vibration turns them....but it is kinda funny you can set them at 10o'clock and 2o'clock and when you pull em out there usually lined up?....maybe thats how zero gap ring were thought up?
never seen one turn but have been told that.
