<div class="moz-text-html" lang="x-western"> Hello Dave,<br>
<br>
I have no argument with you or the Bösendorfer people. There is a
simple misunderstanding as to where the wedges go. The reps are
talking about the top edge of the rim. The wedges go into the TOP of
the saw kerfs and veneer goes over that. See photo.<br>
<br>
The sides are laminated with K 3 board, as one can vaguely make out in
the picture.<br>
<br>
Best regards,<br>

<div>The rim is kerf cut so it can be bent to form to the inner rim,
then filled and glued with wedges. The wedges are sanded and a veneer
is laid over the surface.</div>

<font size="2">The outer rims I saw at the Bösendorfer factory
surprised (scared!) me. <br>
<br>
There was the edge grain spruce, as has been described, but it was only
about 15 mm (5/8") thick. On the inside and outside, a sheet of K-3
board was laminated to it! This is a hard paper press board (think of
a peg board). Then, a sheet of formica is glued on to the outside of
that for pianos that will be black (sometimes called ebony - not to be
confused with that exotic, precious wood). This gives a stable base
for the polyester. <br>
<br>
I understand most companies use the formica trick, but perhaps the K-3
board is the secret ingredient to the Bösendorfer sound ???!<br>

<pre wrap="">You are both correct.
James has described the inner rim, and Paul has described the outer rim. As
of a few weeks ago, that is still how they are made!

spruce edge glued and end glued to gether and then the shape is carved out
of that. That would keep the vibration back to the SB sine there are no

Bosendorfer released a tech video in the late 1980"s(?), of their
manufacturing plant. It showed the rim being kerf cut so it would bend
around the inner rim. The inside and outside of the rim were veneered.

only assume they still do this today.
