I use 100 grid drum paper and the idea is simply to <<scrub>> if you will the insides of the pin hole.  Leaves a very slightly roughed surface with all traces of any burnishing, glazing, foreign substances, whathaveyou removed.  Makes for a very smooth feel to the tuning pins. I almost never find a reason to go up more then one size above the pins I've removed, but there have been exceptions. I have never used pin driving fluid and never found a need to do so myself. Cheers RicB ----------- <pre>I normally used to ream, before repining. However on this latest piano, the pins were tight on removal. Sorry, I forgot to take a torque measurement. I normally just go up one size, unless they are really loose. I am tempted to just go up the one size, and not ream. I do use pin driving fluid. I would like to be reminded of the pros, and cons of each procedure.</pre> <pre>John M.
