Duaine,

The number of turns you need to back out the existing tuning pin depends
on very small variations of how long you cut your wire and exactly how
many coils you make. The number of coils you make, for example, may be
judged by you as the furthest point that you make the coil, which you
may define as 3-1/4 coils. Another technician may define 3-1/4 coils as
3-3/8, knowing that when you release forward pressure the coil will REST
at 3-1/4.

How long you cut your wire can be affected by how hard you pull on the
string after you hook it on to the hitch pin. Do you REALLY pull hard,
or do you apply medium pressure? 

How long you cut your wire is also affected by where you measure: 1. Do
you measure at the front of the tuning pin or in the middle? At the
rear? 2. How do you measure when the tuning pin is VERY close to the
stretcher, making it necessary to bend the wire at a sharp angle to
measure (or do you pull the wire straight from the capo bar above the
stretcher and "eyeball" a vertical measurement to the front/center/back
of the tuning pin for your reference point? If you use this method, is
your head looking EXACTLY perpendicular down on to the tuning pin, or
are you 3/4" off, which will cause you to cut the string at an incorrect
length?)

After a while you will get into a rhythm where you intuitively feel the
variables you need to control to end up with the becket at the same
place on every tuning pin (in a perfect world).

Have fun,
John Parham
