I drilled tuner holes. But first I had to order a 14mm brad-point bit. (Well, it didn’t have to be brad-point, but they work a lot better for this application.)
Hmm, this might not be a genuine made-in-Austria Fisch. New bit on the left, an older one on the right.
In any case, it did a good enough job on four holes.
And here’s what it will look like (sort of) when I install the tuners. Use your imagination to add an inlaid logo, a truss rod nut cover, and a super-smooth finish.
