Thanks for your input. I have also noticed the different technique =
needed to set the string during fine tuning. Firm test blows usually =
have no effect, I have to make more micro moves with my hammer to place =
the tension properly, in the tenor and I was wondering if the material =
under the felt would fail causing it to cut a channel making it contact =
more of the understring felt. I like your idea of the brass half round =
with thick understring felts and I'll experiment with this if time =
permits.=20

I'm starting to do more with major repairs and refurbishing of original =
components and I frequently check the archives of this list to see what =
alternatives others have used sucessful or not. Thanks to everyone!

  David,

  Here's my thoughts, others may disagree.  The Steinway tenor =
understring felt develops a grip on the strings over time which becomes =
the most obnoxious impediment to reliable rendering of strings during =
tuning.  Unless you absolutely have to remain true to S&S original =
design, consider a low-friction substitute, such as brass half-round.  =
You can lay a strip of thick felt on either side of the brass to damp =
the duplex, but the brass supports the string and allows it to move =
during tuning.  As seen on many fine asian pianos.

  Mike

    Greetings,=20
    I need some information regarding exactly what the material is that =
supports the forward understring felt in the tenor section on the =
Steinway grand. I'm working on a ex-player "O" which received has some =
updates, more like down-dates. I'm unsure what to use to support the =
cloth on that slope on the plate. Anybody has any suggestions?=20

    By the way....The soundboard crack repair system of Bill Spurlock =
was a first time for me and with proper set-up of jigs and guides it was =
a pleasure to use. Very close to the bridge for cracks going under the =
bridge itself. I still used the hand carved method for in-between bridge =
and bass apron where the set up would not fit. Real professional =
looking.=20
