A splined shaft can be defined as a shaft with several grooves cut in the shaft. All these grooves are equally spaced around the circumference, and they form a series of projecting keys. They give the shaft a shape that helps it fit into an internally grooved cylindrical member.
What is a spine in golf shafts?
A Spine should be visualized as a backbone or ridge in the golf shaft, running down its length, more resistant to bending than any other part of the shaft.
What is a Spining service on golf clubs?
The spining service — installing or re-installing shafts so that their spines all point in the same direction — is touted as a way to improve the consistency of feel and performance within a set of golf clubs.
Do steel shafts have spines?
Just like graphite shafts, steel shafts also have spines. Being heavier, it is sometimes trickier to find the spine of a steel shaft but they are there and you can use the same method as described above to find it. This is an interesting one, especially with the modern adjustable drivers we now see everyone use.
Are your golf clubs aligned with your spine?
The best way for the spine to be aligned in a golf club is with the spine being located downline of the clubhead. If the spine is aligned directly with the clubhead, it can cause some issues with both distance and accuracy. Having your golf clubs pured only makes sense if it is going to give you an increase in performance.

Do you need to spine a golf shaft?
It is thought that by spine aligning your shafts you will create more consistency in your game and reduce your shot dispersion. This process can also help improve the feel of your clubs during the swing. These all seem like outcomes most golfers would want to have in their bag.
What swing speed requires a stiff shaft?
between 97 and 104 mphStiff – This range is still considered fast, but you most likely won't be out on Tour anytime soon. If you're between 97 and 104 mph with the driver, you need a stiff flex. Regular – Now we are getting into the range where a majority of recreational golfers fall, and also where many LPGA pros fall.
Is a stiff shaft better for a slice?
Try a more flexible shaft, when a shaft is too stiff the clubface struggles to turn back to square, which will present the clubface open at impact, causing the ball to slice. The more flexible the shaft is the easier it is to turn the clubhead over at impact.
What shaft is better for a slice?
Unlike the pros, you should look for shafts with weaker tip sections that allow for more release of the club head as it comes into impact. A more active tip section will generally allow for a faster rate of closure, which is beneficial to golfers suffering from a slice.
How fast should you swing a 7 iron?
An average golfer will swing a seven iron about 75 mph. This number can change based on the weight of the club and if it is steel or graphite. The faster you swing a seven iron, the further it will go. If you can swing at about 85 mph, you will see distances closer to 165 yards.
Can a high handicapper use stiff shafts?
Stiff shafts are appropriate for men with single-digit handicaps as well as some with handicaps 10 to 15 who have high clubhead speed. Stiff flex is available in graphite or steel.

How do I know what shaft flex is right for me?
Some General Guidelines About Shaft FlexTake a look at the distance you hit your driver. ... If you have a very smooth swing, you might benefit from a softer flex even if you swing fast. ... If your drives go left, you might benefit from a stiffer flex; if your drives go right, you might benefit from a softer flex.
How do I know what golf shaft to use?
Briand's recommendation is to use your current driver shaft as a baseline. If your shots tend to be low and with little spin, try a slightly softer flex. If your shots are ballooning, try a stiffer flex. If you're caught between two flexes, you can “tip” a softer flex to make it stiffer in the tip section.
Will I lose distance with a stiff shaft?
If the shaft flex is too stiff, your average distance will remain low.
Can regular flex cause a slice?
When the clubhead gets to the ball, the shaft won't unload properly and the face will remain slightly open, causing a slice. Other swing problems also can cause a slice, of course, but shafts that are too stiff can make the problem worse.
How do I know if my driver shaft is too soft?
If a golfer is using a shaft that is too flexible, here are the likely results:The ball will possibly fly higher for any given loft. ... The ball may tend to draw a bit more from the forward bending of the shaft at impact causing the face to rotate past square to be slightly closed.More items...•
What is the spine orientation in golf?
Golf Shaft Spine Orientation. There are two main positions that you can align the spine in, the swing plane and the droop plane. This is explained in detail in this article but it is felt that most benefits come to the golfer when the spine is aligned in the droop plane orientation. The swing plane means that the spine is perpendicular to ...
Why do you need to spine align your shafts?
It is thought that by spine aligning your shafts you will create more consistency in your game and reduce your shot dispersion. This process can also help improve the feel of your clubs during the swing. These all seem like outcomes most golfers would want to have in their bag.
What is swing plane?
The swing plane means that the spine is perpendicular to the clubface and the droop plane is parallel with the clubface. This is a piece of advanced club builder knowledge that can make a difference to the feel and performance of your clubs.
What is pure shaft positioning?
PUREing is probably the most famous method of optimising shaft positioning and it was invented by a company called SST (Strategic Shaft Technologies). PURE stands for P lane of U niform RE peatability. This is a proprietary process that they claim is accurate to one degree.
What is a vice in golf?
A vice holds the grip-end of the club so that you can test the club. Although it important to point out here that this should be done without a grip on the club. From there you need to find the balance point that gives the club perfect oscillation, then you need to mark the shaft.
Do graphite shafts have spines?
Yes, they do. Graphite shafts have come a very long way in a short period of time thanks to new manufacturing methods and materials. Graphite shafts actually have two spines, creative called “S1 and S2” by the industry. These are the two stiffest oscillation points.
Is golf a hard sport?
Golf is a hard sport to play and many things are uncontrollable during a round. A gust of wind, a bad bounce or other bad breaks are out-with your control.
What is a spine?
The spine is the part of the shaft that is more resistant to bending than any other part.
What can be done?
I start by finding the shafts spine, once found, I align and install the shaft into the club head so the spine works with your swing and not against it.
An added benefit
On a graphite shaft the normal position for the shafts spine is face up, this gives the shaft optimum resistance to shaft drop. (For info on shaft droop read up on the effect of shaft flex and club length on lie angles on the loft and lie page)
Some history
In February 1999 the golf’s governing bodies modified the rule on golf shafts that required all shafts to “bend symmetrically in all directions”, they decided it was no longer against the rules to orientate the shaft in the club head, as long as the shaft imitated the effect of bending symmetrically (you are not allowed to orientate the shaft to make a club that produces a draw or fade)..
Shaft orientation also know as spining, puring, or optimizing USGA Ruling
Because of a change in the interpretation of a USGA rule. Rule 4-1b states: b. SHAFT The shaft shall be generally straight, with the same bending and twisting properties in any direction Appendix II 4-1b states, BENDING AND TWISTING PROPERTIES.
Some science
An independent study on spine alignment was undertaken by Golf Science Consultants Inc, performed by J.
What Others Say
Tom Stine, PGA Tour Partners Magazine. September/October 2002: “The bottom line is that if the spines are not set in the club heads at the proper angle in relation to the clubface, we are not getting the most out of our golf clubs and we will continue to have golf clubs that will perform differently than others.
What is the stiffest plane of a golf shaft?
For our purposes, the spine of a golf shaft is the stiffest plane of the shaft. Finding the stiffest plane can be performed by several different methods. One method is by using the Lockie board. When a shaft is placed on the board and bent, a state of equilibrium exists when the weaker plane is the bend plane.
Where is the Penley shaft located on the Autoflex machine?
Since Penley shafts are checked on the Autoflex machine which marks the weaker plane, graphics are placed on the shaft with Penley located 90° from the Autoflex mark (on the spine).

If you think it's going to make a difference, it will I think, but if you think it's rubbish, it probably won't.

I have hit identical heads with identical shafts, the only difference is that one was pured. To be honest with you i used to play professional golf and there is not that much of a difference that is worth spending an extra $150 to get your shaft pured or whatever they charge for it.

It's all depends on the individual golfer. If they are a low handicapper (mainly scratch and pros) have the same repeatable swing, then having their clubs pured would reduce any dispersion that was not due to their swing. This would be a valuable investment for their tools of the trade.
