Locating Aliquots on Steinways

[Gilreath@aol.com]

Restringers,

I recently ran across some information that I picked up in a class in
Albuquerque on restringing.  The class was taught by Greg Hulme and included
a chart on locating aliquots on Steinway pianos.  He received this
information from someone at Steinway many years ago.  (BTW, for anyone who
isn't familiar with the process, they use a metal template in the factory for
positioning.)  I haven't used the figures or experimented with them in any
way, but I'm just passing them along in hopes that they might be of use to
someone.  The original patent calls for the length of the duplex section to
be a specific fraction of the speaking length.  If the aliquots are in the
position originally set by the factory, I certainly wouldn't change the
dimensions without a good reason.  For positioning, two indexing holes
drilled through the bar and the plate before unstringing wil allow easy
repositioning upon reassembly.

The instructions are reproduced as follows:  Dimensions at notes indicated
are along line of string from rear line of rear bridge pins to bearing line
of Duplex Scale.
