My playing partner loves messing around with his equipment and spends a fortune on it. He recently had Project X shafts pured and put in his Hogan blades and he swears by them. Last week I took his advice and had a Fujikura Tour spec Spd -660 TR pured and put in 9.5* TM R510 TP head. I am hitting this club better than any other driver I have hit i am not sure how much this is down to the puring as the shaft is top class. Puring is not cheap . Is there anything in it or is it just a gimmick? Check out www.sstpure.com to find out more.
Pured shafts anything in it?

It is so important, I want to become authorized to do it.

I found this at the horsepowergolf.com site:
By spine and flex testing the assembled club prior to final epoxying of the head to the shaft, our technicians are able to precisely align the principal axes of inertia of the club’s separate head and shaft components.
Without this precise alignment, motion of the club through the swing arc causes the club head itself to rotate about what dynamicists refer to as a “non-principal” axis.
Such a rotation produces a rigid body “Wobblestone” effect load from the club head onto the shaft, causing the head to experience a “second order small” (minute) rotation relative to the shaft as the shaft flexes slightly under this load (force).
This minute rotation induces a similarly “second order small” misalignment of the club face as the club strikes the ball. The physics of this load induced rotation holds true every time every club strikes every ball. Although this rotation is extremely small it can be virtually eliminated if we exactly align the principal axes of the shaft and the club head, minimizing the resultant rotation about any club head “non-principal” axis of inertia.

Is the www.sstpure.com offering the same kind of thing that www.swingsync.com do?

I figured out how to pure a shaft myself...takes some doing and time. There is such a dramatic difference it's not funny. Wish I had the machine.

Henry-Griffitts offer it as an extra and it makes so much difference even Mizuno Joe may agree if he tried it one day.

But they used steel shafts!

Brian,
May I suggest you visit: http://www.tutelman.com/golfclubs/profiling.php?ref=clubmakeronline
Tutelman has a fantastic site. As an Engineer I've been following his (and others) work on the various methods of defining the spine. I've built the NF2 and NF4 to his plans. It is amazing what they have been doing.
In my opinion, if you go to a clubmaker and he poo-poo's ( a technical word) or doesn't do spining, flowing or profiling the shaft for you club find some one else.
I think you will find everything you need from his site. I'm sure he would be able to answer all your questions.
He's like you ...... one of the best in the world in what you do.

Jim this ? is not directed at u specifically but u or somebody else who is an SME may know the answer
is this legal under the rules of golf for competition play ?

Hello CJ,
I'm not sure what the rules say, but .....
Since I'm not modifying the hardware it is possible that the shaft could be assembled to the head in a random manner and have the spine in the proper location. Thus, I'm taking advantage of a "natural" characteristic of the shaft. This "natural" characteristic is a function of the manufacturing methods used.
