In the matter of setting the tuning pin height by "pre-installing" the
tuning pins, no one has mentioned that different string diameters will
make a difference to tuning pin height if you want to do a first-class
stringing job.  One procedure was to use the tuning pin height on c88
and duplicate that for the rest of the tuning pins.  Another
contribution mentioned leveling the strings as they came off the tuning
pin.  Both good suggestions, but put them together and you'll have
trouble.

When string diameter changes from 0.775mm on #13 wire down to the tenor,
then even to 1.600mm for some bass string cores, if the _tuning pin
height_ is the same, the wire will be much lower coming off the tuning
pins with the fatter strings.  Does it make a difference?  Our
experience is that it does.

I like Susan Kline's method of waiting until coils are raised and set,
the strings are up to tension with a chipping, then the pins are tapped
to their final height.  Here is what Susan wrote:

I think its better to leave the pins a shade high when you drive them in
the
first time, then use the Instacoiler, neaten the coils (they'll need a
lot
less neatening than with other methods), then do a rough chipping, and
THEN
level them the last bit with the shank and punch. That way they end up
_really_ uniform in height.

We speed up the leveling process by setting the first and last tuning
pins of each row in each section (usually six pins) and simply using a
straight edge to level the rest of the rows.  We can work with several
pins at once and do not get near the newly refinished plate with any
guage, metal or wood.
