Q:
What is aligning the shaft?
A:
Shafts are not uniform around their long axis. Depending on how they
are installed in the clubhead--meaning which way the logo points--up, down,
sidways, whatever--they do not have the same frequency (stiffness) in each
orientation. Very expensive shafts have little of this variation,
but that's why they cost $80-$200 apiece. However, less expensive
shafts can be made to work as if they were the more expensive ones by the
way in which they are aligned in the clubhead. (Note: this
can result in a silkscreen logo, such as on a graphite shaft, to point
any which way when the club is assembled. And they do!).
