"do you have any recommendation for drill bit sizes?"
my pins, as stated, ared 2.9, 3.4 and 3.9mm
I drill 2, 2.5 and 3.4 respectively and "ream" the holes with tapered
swages I made to match each size.

OK: accepted practice.
I drill to a depth of 19, 22, and 25 respectively. My pins are 50, 53,
and 56 long, the tapered ends roughly 7, 10 and 12 long.
the number of windings is personal preference; normally the overlength
is the measure but one does shorten this towards the bass to compensate
for increase in wire Ø. Pin height above the WP is normally constant
but the height of the windings on the pin are governed ONLY by the
height of the nut; obviously rising ans nut gets higher (if it does;
italians usually do not) and the pin gets close to the nut in bass. So,
proximity, wire Ø and nut height tell how high to wind. Too much
downdraft in the bass is bad in every possible respect.
All this should make it blatantly obvious why "historic" type pins
without holes are at a BIG advantage. OR viewed from the other side,
why zitherpins are not good; the holes are almost always too low.
Reason enough NOT to use such, even if the square tops and clumsy
tuning were not an objection.
