I was working on my piano this evening, and I noticed two problems, and I wanted to get some input before I proceed.

?

1.? When?I play one particular note, I hear a clicking sound.? It is from the action, not the key.? I believe it is the jack rubbing against the underside of the butt, and the buckskin in worn off.? When I pull the jack back with my screwdriver and release it, it does make the same kind of sound.? And when I press down on the key, wait a few seconds, then release it, I hear it too.



The jack return felt, which is on the butt under the buckskin, has come off.?That's a very easy repair. Without removing the action, take a small piece of felt and put glue on one side. Use a pair of tweezers to put the felt in place, while using a?small screw driver to trip the jack. Once the felt is in place, use the tip of the screw drive to keep the piece of felt in?place when you remove the tweezers. Then allow the jack to trip and push against the felt. It will stay there.
?

2.? On a few notes I hear what sounds like a faint squeak.? I believe it may the front rail pin rubbing on worn bushing cloth underneath.



Isolate where the squeak is coming from by?moving each part of the?action independently,?starting with the hammer, until you?hear the squeak.Then figure out how to eliminate it.?It most likely will NOT be?the?front rail pin rubbing against a worn bushing.
