adjustment screw finally gave up. It took a beating when I sanded the
last couple of fretboards. So I took parts from a scaffolding clamp I
found outside (work is under way on the facades of my building),
chopped it up and made a screw 30 times sturdier.
Now I really need a proper motor. Or at least a better way to mount
the power drill. Those discs that go onto the axis, for the what's-it-in-
english...
