Closing the soundbox after some fixing to the f-hole edges and casein/lime glue size.
Top 68 g 346 Hz/153 Hz
Back 98,5 g 343 Hz/180 Hz
Coupling modes back/ribs 299 Hz, 356 Hz, 526 Hz. Stiff cross grain back gives higher M5 coupling than expected. I think it is ok like it is, but there is room for taking B1+ down later.
