Greg,
I work for Pfizer in Groton, and live in Waterford (just a couple of miles
from Groton). If you happen to be in the area some weekend and want to play
golf, let me know and maybe we can get together.
As far as the "straightness finder", I built a very simple device using a
2x4" with two eye hook bolts spaced 36" apart. The tip of the shaft goes
into one, and the butt into the other, and then you just rotate the shaft to
identify the low and high spots in the middle using a ruler. On the steel
shafts I checked, some were quite straight, and some had a definite high and
low spot (3-5mm from low to high or so). I oriented the low center spot at
12 o'clock in my clubs so that the shaft would load into the pre-bent side
of the shaft at the top of the swing (shaft is 90* from impact position at
the top). This orientation should also decrease toe droop on the downswing,
I think! Hope this helps.

P.S. I think Corey made a more complicated device which uses a gauge that
can measure changes in thousandths of an inch, but I was able to see the
high and low spots by eye. On the straighter shafts, it was more difficult
to identify the low and high spots on the shaft, which I'm sure is easier
and more accurate if measuring in thousandths of an inch.

Hi Tedd,
Hope New England has been treating you well. Actually it was residual bend I
would want to measure. Since we are all forced per se to deal with the rules
of golf as presented by the USGA, spine effect can not be situated in a club
to enhance play. A device like the Neufinder and something to reliably
measure the straightness of a shaft will go a long way toward identifying
"potentially defective" shafts, i.e. shafts with a large spine effect or
residual bend.
BTW, are you anywhere near the Groton area. I'm spending the summers in
upstate Mass. and have friends down near Foxwoods.
Take care,
Greg
