curing loose t-pins w/sandpaper

[Clyde Hollinger]

Friends,

I service an old upright with several very loose low bass tuning pins.
Two of them won't even hold a pitch.  I tried epoxy on them, but that
didn't work.  I'd like to try sandpaper in the holes.

For those who have done this successfully, what type of sandpaper and
what grit do you use?  Can I just drive the tuning pin in the hole after
fitting a sandpaper shim, or should the pin be turned in?  I'd like to
give this a try on Monday.  Thank you.

Sincerely,
