Tapered Tuning Pins

[Farrell]

I would use my drill press and an angle that matched the original (assuming
the original angle was acceptable). There is nothing magical about the 7°
thing. I don't know where that ever came from. In a new hole, drill an angle
that gets the hole about perpendicular to the string line - I think some
folks will angle the hole back maybe 1° or so from perpendicular (figuring
that after tension is applied the pin will rotate forward a tad).

do you simply bore with a hand machine letting it follow its way in the hole
itself ?
