[pianotech] GH-1s etc.

I was referring to how thin the copper needs to be.  Depending on various
factors and targets, sometimes bichords end up pushing the copper down to
something much thinner than string winders are comfortable working with.

small relative to the core that it's better to go with tri-chord wrapped.
You need a good string maker, of course. I know a lot of people reject
trichord wrapped strings but I find that there is sometimes a place for
them." 
 
David,
I'm not understanding your statement/logic. You were referring to the
differencce between Bichord and Trichord windings? If so, then your premise
is incorrect. If the windings size is to be considered in relation to the
mass of the overall note, then the Bichord windings equivalent would be
larger than the windings of a Trichord!  I firmly believe that there is no
good reason to use Trichord wound. They create all kinds of undesireable
anomolies that can be avoided, (for the most part), with Bichord wound in
it's place. There is exceptions to this, however. In the case of 7' & 9'
pianos, where the Bichord windings would be too large, for the given note,
making string spacing/damping an issue. Then, Trichord wound would have to
be used, as there would not be an appropriate wire size in plain wire
advised.<G>

Best,
Joe
