Gluing down the nut

The nut is made of the same stock as the bridge, and was glued with the same padded-nail technique used for the bridge:


Notice that the tuning pin holes have now been drilled. The tuning pins have a diameter of 4.5 mm, and the holes were drilled with an 11/64" drill bit (4.37 mm). As with the bridge pins, the holes need to be a bit tight (0.1-0.2 mm undersize) to ensure a good grip, but tuning pins do need to be free to turn. My tests with scrap walnut pieces suggested that 11/64" is fine, if maybe a bit tight, but I expect these holes will loosen up a little over time.
