How to spine align a golf shaft - Is Pureing a waste of your money?
There is probably no single subject that is more controversial among golf clubmakers than the issue of whether aligning a shaft a certain way in a clubhead affects the way the club plays.
Call it Pureing, Spineing, spine align, or anything else, they all mean the same: finding imperfections in the golf shaft and then aligning the shaft in the clubhead in a way that eliminates any adverse effects from the imperfections.
First, a little bit of technical information: Steel golf shafts start out as a flat piece of metal; then they are rolled and a seam is welded from the tip to the butt. Similarly, graphite shafts start out as long, multiple sheets of graphite, which are rolled and sealed. Because of their very nature, steel shafts have one seam or “spine,” while graphite shafts have multiple seams or “spines.” These so-called spines may or may not have an effect on the ultimate direction and trajectory of a golf ball.
Read on! Lets look at some facts:
The average swing speed for a woman golfer is 62 mph; for the average man it is 84 mph; for the average pro it is 108 mph; for Tiger Woods it is 130 mph.
The golf ball only stays on the clubface of a driver for about 0.0004 seconds, regardless of swing speed or club used!
At 100 MPH swing speed, the ball is touching the clubface for only 0.7 inch of the swing.
But, the most amazing fact is that during that extremely short contact, the clubface can rotate as much as 2 degrees!
And, while a 2 degree shift of the clubface may only account for a 4 yard off-center dispersion on a 200 yard drive, it simultaneously causes serious side-spin that can send a slice or hook 50 or more yards off-center (and into the woods)!
To help eliminate the shifting of the clubface during the contact with the ball (and even before the contact), a golf shaft, first of all, needs to have adequate torque (or twisting) resistance (imagine using a shaft that is like cooked spaghetti – it would turn off-center as soon as the ball is struck). Similarly, cavity back clubs add weight to the heel and toe to keep the clubhead from twisting when the ball fails to contact the clubface “sweet spot.” These are, of course, equipment solutions.
Now we approach how to best align (or pure) the shaft itself in the clubhead:
Probably the best method of pureing the shaft to eliminate the effects of shaft irregularities, is the patented method used by the SST Pure Company. Their computerized process is the most sophisticated and accurate on the market. Their services are available through Golfsmith only, and their pureing ranges from $15 - $50 for a single club.
As the next best method of pureing, our Professional Model Spine Finder places stress on the full working shaft length (even with a grip still attached) to quickly and accurately determine the location of the “spine.”
Using our easy to follow step-by-step written instructions and our instructional DVD, you will easily learn how to pure a shaft and then align the spined shaft in the clubhead in under a minute. You can pure your entire set of clubs; every set of clubs you will ever own; your friend’s clubs; and your friend’s friend’s clubs for a one-time cost of less than $60.
And, if you want an even less expensive spine finder, check out our entire line of spine finders starting at less than $30 at www.golfperfect.com . Plus, all of our spine finder alignment tools come with written and DVD instructions and a free full copy of our bestselling Clubmaking / Clubfitting / Swingweight Software!
Make no mistake - this whole subject area is controversial, with some people swearing that pureing a golf shaft is the ultimate alignment method, while others claim that it is totally worthless. And, both sides claim to have the incontrovertible science to back up their opinion! Needless to say, there is no industry standard to settle this issue.
Despite the controversy, all we can say is that we have great feedback from our customers, and those testimonials make us think that shaft pureing / spine alignment is the way to go, especially for the average golfer who may need just a little help curing a slice.
Of course, all of our products come with our Unconditional Money Back Guarantee.
