Using sandpaper on tuning pins.

[Barbara Richmond]

Hi Ron,

Well, I've used sandpaper shims with success on a couple pianos.  One in particular was at one of those churches where they had a problem keeping the strings on the piano (they plowed through a set of Yamaha hammers in a little over a year!) , so I was continually putting new strings on.  I was in a pinch (that means I wasn't really prepared), so I cut a small strip  (about 3/16"-1/4"w, maybe 1"long) off my well-used heavy duty hammer shaping sandpaper strip which was an old, worn-out cloth backed sanding belt.  I think I put the abrasive side toward the wood. The strip stuck out a bit--I suppose I could have trimmed it, but I wanted to know where it was.   It held for the 10+ years I serviced the piano.  The shim didn't move around, but the tuning pin was secure and held nicely.  Maybe there was something about the cloth back and not much abrasive left on it, that made this shim work so well. This was before I knew about CA glue.  Now I suppose I would try the CA first, since it was worked amazing well on some incredibly loose pins.  If it didn't work, I'd stick a strip of sandpaper in--I retired that old piece of sanding belt to my stringing kit....

        I've heard it mentioned several times that using sandpaper on loose tuning pins is the best way to go. My question is; 

        Do you glue the sandpaper on the pins or? I keep thinking that as you pound the pin back in it will peel off the sandpaper. 

        Also what is the best grit to use?
