I'm referring to discussions last year where it was argued that it was
impossible for wood as a material to support an arch, because of
cellular-level crushing ("compression set").  I believe the counter to =
this
demonstration was to show how little pressure was required to push down =
on
the arch and collapse it.  Therefore the wood alone wouldn't be strong
enough to support string downbearing (for example, the soundboard =
compressed
by the rim, without any ribs).

I don't mean to resurrect the prior argument, but just as in any =
profession,
it's difficult for a student like me to try to figure out what "best
practices" are.
