Bracing and Voicing the Soundboard: a Modern Classical Guitar build

No music, no talk, just the craft and its sounds.
This Soundboard is for my guitar #09, 'Nova', which I have decided to make as a prototype "Modern Classical", i.e. a classical nylon-strung guitar with 'modern' features: a slightly curved fingerboard, an arm-bevel, a cutaway, and with our newly designed Lamella Bracing. Spruce Soundboard over Khaya Mahogany back and sides.
The Lamella Bracing was designed by my brother Eric Crevels and me, inspired by Lamella Structures in Architecture. Visually, it may look like a version of Lattice Bracing, but it has some fundamental differences that make it really one of a kind. This design has a great weight-to-stiffness ratio, and I am very curious about how it is going to sound.
I have made Chladni Patterns using sine waves to drive the resonant modes of the braced soundboard. This way I can visually examine the stiffness distribution over the whole Soundboard, and then act accordingly. The relative position of the resonant modes also gives me insight into how the guitar will eventually sound.

Can't wait to finish this one. I am very curious about how this guitar will sound with the special bracing, but there are also more surprises to come with this one!

[@nicolettadorizzi7719]

How clever to get inspired by the geometry of timber lamella! The result will be a very special one. #lutaio #chitarre #acustica #strumentimusicali

Thank you! It helps to have a brother who is an Architect. We were just wondering how similar the soundboard of the guitar is, structurally, as a hanging roof

[@ericcrevels]

Looking forward to seeing (and hearing) what comes out of this idea!

[@chriscrevelsguitars]

Everything points to something great!

[@echoesofa]

Wow, so cool! Lovely patterns 🔥🔥

[@chriscrevelsguitars]

Thank you!

[@jameslabs1]

Fascinating. Thanks.

[@chriscrevelsguitars]

Well, thank you!

And a spider web kind of structure, have you thought about it? Last day I went for a walk and came across with this idea after observing how resistent it is.

[@chriscrevelsguitars]

Haven't thought about a spider web, but my guess it would be somewhat like a lattice design?

[@ww3032]

Please do a video of how it sounds like when it’s done! Looks amazing so far. I’m guessing it might sound a little like a Sakurai or Kohno.

[@chriscrevelsguitars]

Sure, I'll make some sound samples when it's done. Should take another month or so, however. I'll be very happy if it sounds like the Japanese masters's!

Instead of tea y use saw dust and a violin bow

[@chriscrevelsguitars]

Thanks for the suggestion! Saw dust is finer and lighter, would do but unfortunately not good for our health :/ the problem with the violin bow is twofold: you can't control the frequencies and I don't have one 😂

[@RaulPerez-qe3ef]

control is posible,it depends of the place you rub the bow.Iam using the method for more than forty years,on violins and guitars

[@chriscrevelsguitars]

@@RaulPerez-qe3ef that's interesting! I'll see if I can find an used bow for cheap to try it out
