Rough thickness soundboard

Rough thickness the soundboard—I use my Delta 18-inch open-sided thickness sander to get the soundboard to an even thickness of 0.135 inches. It is actually quite easy to plane the soundboard to thickness, and I occasionally do it that way to stay in practice (and to cut down on the dust and noise).

Planing ebony and rosewood backs is another matter, and I've given up planing them.
