Using sandpaper on tuning pins. CA caveat

[Fenton Murray]

MessageAlthough I have become a fan of CA in many instances, I think it should be mentioned that there are consequences latter. I have pulled a plate from a piano that had it's block treated. This plate was very difficult to get out, I had to hit it with a mallet and was more than a little nervous. Also, any machining of wood with CA treatment should be accompanied by the use of lung and eye protection.
None of this is to knock a good product, just the other side of the coin.

  If CA doesn't seem to be working, remove the pin, squirt CA directly into the hole, reinsert pin. It has always worked for me.

  I've successfully used CA many times on really loose tuning pins. Much easier fix with no chance of breaking the becket or string. I can't see why you would do it any other way. Last, last resort, sandpaper does work, sand side to wood. Determine the grit by how loose the pin is. 80, for really loose pins, 120, for med loose & 220 for, I really should have used CA.

  Ron,
  It does work, if the pins are VERY loose. No need to glue anything anywhere, just roll it up grit side out, pop it in the hole and bang the pin back in. The grit will hold it in place. As for grade, I guess you could adjust depending on how much space you need to fill, but I think I've used about 200ish. Whatever works! You can also try thin (0.5mm/0.020") wood veneer if you have any handy. You would only want to use these for a pin or two, as it is very time-consuming, and you are likely to break strings into the bargain. 

  Have you read about CA glue such as at https://www.moypiano.com/ptg/pianotech.php/2000-May/subject.html#64374 ??? If this is a serious case of pin-block failure, look at wood plugs http://www.alliedpiano.com/pinblock.htm

  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?
