Jason I see you have continued with the (weight saving?) removal of material in the big cross braces.
It would be interesting to see a proper analysis of this. LIke how much weight you can save and exactly what the effect on stiffness and hence functionality there is.
The larger X in the middle of the lattice adds a lot of stiffness. By removing material, I was able to loosen up the top quite a bit.. until I was satisfied.
Regarding removing more of the lattice from the sides- There is a difference between what I'm doing here, and a Smallman style lattice where the sides are beefed up and supported by a large plywood rim. The design I use is less like a diaphragm that's isolated from everything else in the guitar, and more like a cohesive vibrating unit. Therefore, my soundboard requires a little more support from the braces. The feel is more organic, and the sound of the tonewood used for the back and sides is a larger contributing factor.
