Started building my first classical guitar

I put my dishing jig on hold and finally started building.

I glued up a soundboard for my first classical guitar from the surviving remnants of the first billet of Spruce I bought last year. It is not a clear piece and I am lucky that it was usable at all. Fortunately, the soundhole and rosette will cover the most offensive defects. This is a practice guitar.

I found some interesting information about using Chladni patterns for tuning guitar plates after reading an article by luthier Alan Carruth. Apparently, you try to distribute the resonant modes evenly across the spectrum by adjusting the soundboard and bracing. I don't fully understand the practice yet, but hope to gain more insight soon. I found these articles interesting:
