Jude and all,
>. . . I'll just have to try a pure RC&S for myself.
Please do take the plunge. It would have been a real leap of faith
not so long ago. But there are too many examples of successful
attempts out there, which should give you more confidence to leap in.
I believe the purest version of RC&S is to use a laminated panel with
an appropriately-designed crowned rib set. If a solid panel is used,
when building an RC&S board, there remains some assistance from the
re-hydrated panel. This is not however, a criticism of the practice
of drying solid RC&S panels down to 6 - 7%, since it would be quite
dangerous to build any solid paneled board without some pre-drying,
to avoid the likelihood of checking during dry transients. But when a
laminated panel is used, the problem of checking is/will be totally
avoided, and the maker is free to bring the panel and ribs together
for gluing under normal room conditions. This might seem like heresy
to some of the older school piano men and women, but if the rib set
has been designed appropriately, such an instrument will have a very
satisfactory tone, and will be likely to continue doing so for
decades and decades and not just a very few years, as is the case
with some of the contemporary offerings.
Several of the new pianos we've built had a laminated panel,
including the piano we exhibited in Rochester in 2006. Here's an
image of the soundboard for no. 6, just before it was fitted.

These boards, with the piano strung and at pitch, remain crowned
enough for a string line across the underside of the mid-panel to
nearly clear the height of the soundboard buttons. Crown remains over
the entire area of the soundboard, without any of the typical
overloading at the bridge 'lines' and the perimeter of the soundboard.
There's more evolution left in the piano yet. Let's not let the
stagnation of the past century put us off. Let's make the new piano
century one for history in the making.
