Ribs and teeth

Thinning ribs with a toothed plane, to avoid tear-out in the highly flamed maple.  This side will go inward on the finished instrument.

An old task for me, but in a new context.  For the Hardanger, I'll go as I generally do with violin ribs.  For the viola, about 10% thicker.  So 1 mm and 1.1 mm!  Not much, but a difference.
