  Does the U3 set give me enough treble dampers for the 26 bass =
Steinway? And which set of dowel damper blocks do I get to go with them? =
Schaff's #529 pg. 82 of their catalog? Do I need more than one set of =
these? I noticed that on the U1 that I tuned today, the dowels were all =
the same (short) length, and that Schaff's are two different lengths, =
with 'slant' and 'straight' treble. (I'm not sure what that means - I =
thought the whole pupose of dowel damper blocks was to avoid angled =
holes and extra wire-bending). Are you cutting down the treble damper =
blocks on the bandsaw because they don't have enough room between the =
string and the spring rail to work otherwise?
