What is torque in golf shafts?


     Torque is the property of golf shafts that resists twisting during a golf swing. The fact that the shaft attaches to the heel end of the golf club means all the club head weight is in front of the shaft. During the golf swing because of the weights location a twisting force is exerted on the shaft.

     Torque is measured in degrees. The lower the number is better the shaft resists twisting.The range on today's graphite shafts can be as high as 7 degrees and as low as 1 degree. A steel shaft's range, because of the material, is much narrower - a little more than 2 degrees to just under 4 degrees.

     The reason that torque is not a critical fitting factor today is because shaft makers design the torque of their shafts to coincide with the flex. Because a strong player with an aggressive tempo creates more twisting force on the shaft you rarely see S and X flex shafts with torque higher than 4 degrees. With R, A and L flex shafts are designed with higher degrees of torque because a slower swinger exerts less twisting force on the shaft.

    In summary for most players torque is not a factor to be concerned with in shaft fitting. For those who's swings warrant consideration of shaft torque it will apply only to graphite shafts and not steel.

Clubhead Speed Versus Headweight

     A reader sent in a question about headweight and how it affects distance. This is a great question and one that has stirred debate in the golf industry for years. Most people would agree that a lighter club would be better, but if you look closer that answer would need to be qualified.

     A typical driver today is 45 1/2 inches long, has a headweight of 200 grams and a swing weight of D-1. If swung around 100 mph the ball leaves at about 145 mph and carries a little over 245 yards. If you could swing a heavier club at the same 100 mph the ball would not go proportionately faster and  farther. A 400 gram head (twice the normal weight) swung at 100 mph would send the ball at 160 mph. It has also been shown that lightening the head does not substantially increase distance. As the clubhead is lightened a player can swing only slightly faster. 

    As a result we can say there are a wide range of weights and will usually produce the same length for a particular player. As the clubhead gets lighter (less mass) the swing speed increases and as the clubhead gets heavier (more mass) the swing speed decreases. Both of these produce approximately the same distance.

     Engineers and club manufacturers test a multitude of weight combinations to produce a club that maximizes distance. An experienced clubfitter will then customize the specifications - shaft weight, shaft flex and swing weight - based on each player's swing characteristics.

Adding weight to a putter

      I recently had a customer ask if I could add weight to his putter. He had tried a heavier model and liked the feel much better. Adding weight can be accomplished two ways. One is to add lead tape to the putter head until the desired weight is reached. The other is to remove the grip and pour lead powder down the shaft and secure it with a cork. Using a swing weight scale during the process enables you to create the desired swing weight the customer wants.
      Keep in mind shortening or lengthening a putter will alter the swing weight as well. Shortening a putter's length will decrease the swing weight of the putter - lengthening the putter will do the opposite.
     If you have a question about club repair or other equipment topics please email me at stevejkirkpatrick@comcast.net.

Question about driver shaft

    I recently received a question from a customer asking if his driver shaft can be stiffened without having to replace the shaft. The answer is yes, it can be stiffened without having to buy a new shaft.
     We accomplish this by removing the shaft and trimming length off the tip end. After re-installing the shaft we use a shaft extension in the butt end to make the driver the original length. The more you trim from the tip the stiffer the shaft becomes. By using a shaft frequency meter we can determine how much to trim for the required stiffness.
   If you have a question about club repair or clubs in general please send it to me at
stevejkirkpatrick@comcast.net. I will answer it on my blog page as soon as possible.

Think less and play better

    Why do we make the golf swing so complicated? To quote acclaimed instructor Jim Flick, "If as much were written about sex as there has been on the golf swing, life would be extinct by now."
 
    Think back when you were learning to hit a baseball or return a shot on the tennis court.  What were you focusing on? I would imagine it was simply swing the bat and hit the ball, or swing the racket and hit the ball over the net. Whoever taught you to play pitch and catch or to hit a tennis ball  wouldn't give you 3 or 4 commands while you were throwing the ball or swinging the racket. 

    So what make the golf swing any different?  The golf swing takes 1.25 seconds for the average player to complete - not a lot of time for the brain to be giving various commands to different body parts.

     Harvey Penick, instructor to Ben Crenshaw and Tom Kite put it this way when it came to golf instruction, "Take a pill, not the whole bottle." One thing I know is the less you think about during your swing the better you'll hit the ball.

      If you are confused and mixed up in too much swing theory try this next time you play. Hold the club light enough so that you can feel the weight of the club head. Swing at 80 percent focusing only on swinging the club through the ball in the direction of your target. You may be surprised how far the ball goes with such little effort and thought.
