Well, toward the unorthodox methods: bottom plate:
On the delaminated bottom plate i try to look if giving it a "finish" with thinned fish glue will change the tone. The hope is, that it might soak sufficiently into the fine and hardly visible cracks which are everywhere on the inner ply and "glue them together".top, braces:
my current idea is to weaken the braces and to distribute the load on more shoulders.
weakening the braces, i.e. strongly scallopping them should have the side effect to reduce the tension on the glueing connection - the brace will withstand the pressure to a smaller degree and just deform stronger. They are probably oversized anyway, so i will definitely increase the scallopping; the question is just how much.
In addition i might distribute the load on more shoulders, i.e. add one or even two additional braces. Small ones, so that the top actually will have something like a fanned bracing.
This should allow me to further reduce the height of the old braces - carefully, i am aware that the strength changes with the 3rd power of its height but only proportional to the (total) width of the support bars. Maybe it'll suffice to give the additional bars a width of just 4 mm (cut one of the bars i saved from the thinline in two halves...)
What Yo You think of the idea?
