I built this one and works pretty well for me.
Simply use some ball bearings, with an inner diameter of 3/4" or better, and
devise a system for "holding" the bearings. (I use a 6" piece of plastic
pipe). Before putting in the bearings, I screwed a piece of wood (on edge,
at the same axis as the pipe). This is used to hold the device horrizontally
in your vise. The butt end of the shaft is inserted into the bearings, with
about 1" sticking out (to the left, if you are right handed). Then use a
third, smaller bearing, simply held in your right hand (unless southpaw), and
place it about an inch in from the tip end of the shaft (shaft through the
center). Gently press down on this bearing, so that you can feel the shaft
resistance to being pushed slightly down (about 1/2" or so). Now, use the
other hand, to rotate the shaft, (gripping it, just to the right of the
bearing set), - rotate slowly, and you will notice the shaft "up" pressure
ch!
ange. I understand the spine, to be the uppermost surface, when the shaft
is *most* resistant to the downward pressure. Mark the butt, with a line, to
correspond to this spine. (the orrientation, that is the stiffest). You may
now build clubs, with the spine orriented in the way of your choice. I still
hear a lot of controvery on "the best orrientation". I think the spine
should be either facing the clubface, or 180 degrees away from it. I have
yet to hear convincing proof of which is best. The choice will affect
playing stiffness though, - at least the way I understand it.
My unproven thoughts are:
A hitter maybe should put the spine towards the clubface, and
a swinger perhaps the other way. Some real tests of that thought might be
interesting. Some have suggested that if the spine is 90 degrees from the
face, it will have negligable effect on the club. I!
just don't know for sure.
I'd be interested to hear how you ma
ke out with this.
Cheers,
Jorgen

A while back I remember reading about someone's home built spine finder
that involved using 6 small bearings, and I thought I had even kept a
set of basic instructions or at least some demo pictures of it. The one
I was thinking of was from someone who used the bearings in sets of two,
using some scrap plastic pieces from a local source. Does this ring a
bell to anyone here? I thought I had saved the e-mail and
correspondence but now that I have found some bearings I can't find the
original information.
From old discussions I have been able to find reference to a few plans,
such as the Neu-finder from Dan Neubecker (this may be the one I was
thinking of, but I will have to look at the plans again) and Kevin
Cahill's (http://clubmaker-online.com/spinefinder.html) plans.
Any suggestions would be greatly appreciated.
Thanks,
Ron
