Squeeky jack spring??!

[John Ross]

Hi List,
I have had squeaks that were repaired, by lubricating, the balance
rail hole. They were Young-Changs, if I remember correctly.

| Jon,
|
| You've already gotten some good things to check but while you're at
it, I'd
| also check to see that the wippen isn't rubbing the knuckle of the
one next
| to it when the key is played. You said a "rubbing" sort of sound,
not
| "squeak",
| so my mind went to where I've had those kind of problems.
|
| While you've got the action pulled out, I'd go ahead and check to
see if the
| key has warped in the back a little, or was just not cut accurately,
and is
| rubbing the key end felt next to it slightly. Just some thoughts.
Good luck.
| Let us know what you find.

|
| P.S. Another off-the-wall thought. Check to see that the spring you
mention
| that goes into the jack isn't too long and so the end of it rubs
against the
| back side of the jack. I don't remember the brand but I did find
that one time
| a long time ago. In Kawai, probably not, but it's always worth a
look.
