Keyboard: Sanding natural covers

It's time to sand the natural key covers. Some of them turned out to be a little irregular, tapering in thickness from side to side. The seam between fronts and backs also needs smoothing out.

I set up this drum sander on the Shopsmith, making it act like a thickness sander thanks to the Shopsmith's adjustable table height. That way not only are the key tops flattened properly but they'll end up parallel to the undersides:


After progressing from 150 grit to 600 grit and giving each key two or three slow passes, the key tops are smooth as glass.
