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 <A href="https://www.moypiano.com/ptg/pianotech.php/2000-May/subject.html#64374">https://www.moypiano.com/ptg/pianotech.php/2000-May/subject.html#64374</A> ??? If this is a serious case of pin-block failure, look at wood plugs <A href="http://www.alliedpiano.com/pinblock.htm">http://www.alliedpiano.com/pinblock.htm</A> Scott Jackson Mt Keira, NSW, Australia. -----Original Message----- From: pianotech-bounces@ptg.org [<A href="mailto:pianotech-bounces@ptg.org">mailto:pianotech-bounces@ptg.org</A>] On Behalf Of Ronny Boyd Sent: Sunday, 20 July 2008 13:54 To: pianotech@ptg.org Subject: Using sandpaper on tuning pins. 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? Ron Boyd Milwaukee chapter #532   </BODY></HTML>
