Beautiful outcome on the bearing bars. It must tune very well.<br>
The finish is stunning. IS all that original or re-done?<br>
Any recordings of it embedded anywhere?<br>
What hammers were employed in this Yamaha Do-Oversed<br>

<pre style="font-size: 9pt;"><tt>Wim and all,
That counter-bearing system looks to be an ideal candidate for
building a new single piece counter-bearing bar that sits on the
plate, while at the same time being relocated right up to the edge of
the cast web as close as possible to the capo bar. The
counter-bearing lengths on this piano would be better if they were
shorter, and this plate-web fortunately has a minimal distance
between it and the capo - an ideal opportunity for changing to a
shorter counter-bearing. It will really help the treble clarity, and
since one bar has already collapsed, the opportunity is there to make
an improvement while you're doing the repair.
Here's a link to an image of a Yamaha CFIIIs which we rebuilt
recently. This piano originally had three separate counter-bearing
sections per string section, as per Steinway since 1872, and just
about everybody else on the planet these days (we're such an
innovative lot). For the CF, we cut off the cast-in counter-bearing
bars and built up the web with body filler in those places where it
was a little below the nominal web height. We built a new
counter-bearing V-bar from ground stock, hardening it and EN plating
it after hardening. Below is a link to an image of the end result.

The treble clarity of this piano is pleasing. We've got it for sale,
for the owner, should anyone be interested. Doesn't sound like a
Yamaha anymore, but it certainly sounds like something out of our
workshop.
