<BLOCKQUOTE cite="" type="cite">Yes indeed. Now this leads me to =
wonder
just how much longer we might expect a sound board with a properly =
laminated panel to last?</BLOCKQUOTE></BLOCKQUOTE>
<BLOCKQUOTE cite="" type="cite"><BR>Hi Ron,<BR>Wouldn't the =
question more
fundamentally be how much longer will the panel last if we design it =
to be
rib supported rather than panel supported?<BR></BLOCKQUOTE>
<BLOCKQUOTE cite="" type="cite">Ron N</BLOCKQUOTE>
<DIV><BR></DIV>
<DIV>I am assuming that a serious sound board will be rib crowned, but =
a
laminated all spruce panel with rib crowning must surely be an =
excellent
combination.</DIV>
<DIV><BR></DIV>
<DIV>I am assuming that any piano maker worth his/her salt will be =
using the
RC process for crown. I cannot understand how anyone who claims to be =
serious
about piano manufacture would use compression crowning. The reality =
is, of
course, that those who persist in using it are focused on the =
marketing and
not the product. Its a lot quicker to make sound boards with straight =
planed
ribs, while drying the hell out of the panel to achieve a crown which
hopefully lasts long enough for the castors to come to rest on the =
lounge-room
carpet. Recently, Del and Terry were discussing a certain manufacturer =
who
claimed to have achieved perfection by 1930. An Erard representative =
made a
similar claim at an 1880s trade fair<FONT color=#0000ff> (it is =
mentioned
in<I> Men Women and Pianos</I> - but I haven't been able to find the =
reference
- should anyone know the page no. of this quote I would be interested =
to
hear)</FONT>. And where can the famous Erard be found today outside of =
Museums?</DIV>
<DIV><BR></DIV>
<DIV>The logical conclusion we can draw is that claiming perfection is =
an
admission of 'pending corporate death'. Certainly one swallow doesn't =
make it
summer, but here we have two swallows. There's always some-one waiting =
in the
wings to carry the banner forward.</DIV>
<DIV><BR></DIV>
<DIV>Regarding the fit-up of flat bridges to crowned sound boards, as =
I think
one other technician mentioned on the list, we are talking strictly =
about the
fit-up of a logarithmic style long bridges. Hockey stick long bridges =
truly
are 'dust bin' technology.</DIV>
