Soundboard types.. was The soundboard bit.

[RicB]

I would just add to this that the RC description here is not accurate at 
all.  It is hardly "really the same" as the RC & S board.  In many if 
not most cases it is closer to the pure CC board.

A RC board can be said to have curved ribs... but beyond that it can 
either rely largely on panel compression and the stress interface this 
creates with the ribs, or it can be a pure RC and S board.  All depends 
on how much compression the whole assembly process ends up putting into 
the board.

    Don,
    I do hope that someone (Ron N or O, or Del) clarifies their position
    on RC v. RC & S. My understanding was that RC & S did not require the
    soundboard panel (and ribs) being dried prior to glue-up to the extent
    that the classical RC method calls for.
