How do you duplicate an original soundboard when most often you don't know if or how much a radius was machined into the ribs, you don't know what radii cauls may have been used during rib-to-panel glue up, and you don't know the panel moisture content at rib-to-panel glue up. So if you do it the way you want to, are you not redesigning the soundboard?
