How does one determine the perfect position for the shim? I can imagine =
this to be a fairly easy task on an action that has keys of equal =
length. But this piano is a nine-foot Wissner where the bass keys are =
longer than the treble keys - so its not like I can just set up a jig =
with a "good" key and make the repairs to match the "good" key - all the =
keys are different lengths. Ideas?

    Is there any danger using a hard-wood veneer like maple that it =
might be noisy? Is there any preference to use something a little softer =
- like maybe fine-grained spruce or poplar?

    > Hi Terry,
    > I have had great success repairing this type of damage using maple =
veneer. Mount a balance rail pin in a scrap board, position key upside =
down and saw a kerf the thickness of the veneer about 1/4 inch deep =
using the balance rail pin as a guide. Glue the veneer in this kerf and =
you will have a permanent repair. =20

    I've done this many times for 20 years with no noise problems from =
the keys.
