Noisy action

[David Ilvedson]

Jeannie,

I have a customer with Feurich 6' 4" grand, Renner action.  I came into the
situation where he wasn't touching the piano and hated it because of the
excessive action noise.  What I ended up doing was regulating the height of
the jack in the wippen, which was low.  The noise lessened quite a bit.  I
checked the pinning on the hammer flange and found the pin loose in the
birdseye.  I ended up repinning the entire action.  He now loves the piano
again.  Check the height of the jack, its position with the knuckle and the
pinning.  

Good luck

David I.
