[pianotech] GH-1s

[David Love]

I've done the D both ways (in fact the Hamburg scale uses bichords), but a
few years ago I redid a Steinway O with a semi transition and had Delacour
rescale it for me and he produced a set of trichords wrapped for a section
and it sounded great.  No problems.  We discussed the issue of bi versus tri
and he convinced me that the tri would sound better.  Having had done this
on another piano with bichords I agreed with him.

I prefer bi-chords to trichords as well but sometimes the windings get so
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 Love asked:
"I presume you changed those to wrapped strings or something without
changing the bridge. Did you use wrapped bichords or trichords, if you
recall."
 
David,
You presume correctly. Wound Bi-chords. It is necessary to add 3 hitch pins,
equi-spaced, to make it work.<G> It's not the very best, but it does make
the piano resonably tunable and stable in that area. Of course, ya have to
warn the client that you'll be, somewhat, living with their piano, forever,
until the strings stabilize. Another issue is that the piano will really go
whacko, pitch-wise, when you remove the lower bass strings to do the install
of the hitch pins and strings! Be aware of it and it won't freak you out
...too much.<G> Once the strings are on and the lower bass strings have been
re-installed and then tuned, it goes pretty much right back to were it was
before you started.
BTW, I try to avoid wound tri-chords if at all possible.<G> Best, Joe
