Treble resonator

[Cy Shuster]

In Del's small grand class at PTG 2000, I seem to remember him saying it's
the long straight side of the rim that needs bracing.  I wonder why they
brace this side?  Just because the treble side of the soundboard should be
stiffer?

would deter outward movement, but wouldn't a good solid hunk of timber be at
least effective in stiffening the belly rail and preventing any kind of
movement of the belly rail or rim - either way (not that I think we are
really worried about significant movement)? Seems to me a good timber in
there might even have more effect on stiffening the belly rail as it might
be easier to make a more massive (dowels, epoxy, etc.) bonding mechanism
between the timber/rail/rim?
