Yamaha Shank Weights

[stanwood]

We use Yamaha shank weights in certain cases to "mock up" a customers action
to help determine if they like the tonal and tactal changes of increased
strike weight.  If they like it then we permanantly add hammer mass either
by replacing with a heavier hammers or by inserting and appropriate amount
of hammer leads to the molding of the existing hammers.  We use .109" pure
lead wire expanded into a drill hole using a tiny arbor press.
