<HTML><HTML>Greetings,            Up in piano tun= ing school, we were advised to lay the piano on it's back via a piano tilter= and use CA glue, or the old formula of violin rosin mixed with alcohol as a= tightening agent for loose pins.            Also, if the si= tuation is bad enough, a piece of 150 grit sandpaper could be cut in about a= 3/8" wide strip, the length of which would be twice the circumference of th= e pin, folded in half width wise and wrapped around the pin and put back in = the hole. The folding in half width wise, allows you would wrap the grit tow= ards the outside of the pin and there will be grit surface towards the insid= e of the pin, so that the grip occurs between the pin and the block's hole a= nd the pin and the inside of the sandpaper.            I never had to = try it yet as I have only been tuning for a little over a year. It worked at= school and I would try it if I had the need. Hope this helps. Julia Gottchall, Reading, PA  </HTML>
