Precision Tools For Custom Clubs 

The picture above shows a NF2, a device used for finding and marking the spines and neutral bending points (NBPs) on shafts. The gauge on the left is accurate to 1/1000th of an inch, allowing for exceedingly accurate determination of spines and NBPs.

 

Frequency and Torque Analyzer

 

 

 

 

 

 

To build a precision matched set of clubs a frequency analyzer is a necessity. Torque is also a critical parameter in selecting a shaft, particularly graphite.  The Club Scout III is a precision microprocessor based golf shaft analyzer that measures both frequency in cycles per minute and torque to a tenth of a degree. The Club Scout III measures torque of a raw shaft or a finished club by attaching a calibrated torsion arm to the tip of the shaft. The butt end is firmly held in the clamping unit. A support bracket under the tip of the shaft restricts the shaft to twisting motion only. Tapping the end of the torsion arm causes the shaft to oscillate in torsion. The electronics unit measures the torsional frequency and converts it to degrees of torque accurate to 0.1 degrees. 

                                Loft & Lie Machine

   

  Loft & Lie adjustments

A crucial component of a golf club is the correct and customized LIE ANGLE.

  • Lie Angle (middle and short irons)

    The Lie Angle is the angle between the shaft and the sole of the clubhead. A proper fit Lie Angle means at impact, the center of the sole brushes the ground, so the toe or the heel of the clubhead are not tilted upward. The greater the Loft of the club, the more off-line the shot will be hit if the Lie Angle is not fit properly to the golfer. As a result, it is critical for accuracy that the Lie Angle of the middle and short irons be properly fit to the golfer.

    The proper Lie Angle has to accommodate the golfer’s height, arm length, and posture of the body at impact with the ball. Therefore, golfers who buy standard clubs “off the rack” have less than a 20% chance of the standard Lie Angle being correct for their physical make up and swing. Lie Angle is adjusted to fit the golfer by bending the hosel of the ironheads using a specially made machine. Professional clubmakers are trained to fit golfers for the proper Lie Angle and perform the required bending alterations to the ironheads.

    Lie angle matters because a club that does not have its sole perfectly flat to the ground when it strikes the ball will create directional errors in the shot. Too Flat of a lie angle will cause the toe of the club to make contact with the ground first creating shots to fly right of the target (right hand golfer/left for left hand golfer). Too upright of a lie angle will create an opposite effect.  Without the correct lie angle the golfer must adjust his or her posture and swing to accommodate for the club. Playing golf with clubs that do not have the proper lie angle for you, results in making the game more difficult, through inconsistent shots.

A quick self check to determine if your lie angles are correct for you. 

1. Were your current clubs fitted for someone else?
2. Are your divots deeper on the outside edge versus the inside edge?
3. Does the divot line (the dirt line that develops on the face of your irons after repeated use.) run at an incline across the face of the club?
If you answered yes to any of the three questions you are in need of at least a lie angle check.

  It is not uncommon for loft & lie angles to change through normal use of a golf club. Serious golfers should have their lofts and lies checked quite often throughout the course of a season.

LOFT

  The height of the shot is chiefly controlled by the loft of the clubhead.

  The Trajectory, or height and shape of the ball’s flight in the air, is a critical factor that contributes to Distance in irons. If the ball does not achieve the proper trajectory for the golfer’s swing speed and swing movements, it cannot fly and carry to the maximum distance of the golfer’s swing speed.

  While you may hear some golfers speak of a “penetrating or boring” trajectory being ideal, for golfers to fully maximize their distance potential, they will have to become comfortable with a higher ball flight.

.  The greater the loft, the higher the ball flight, and vice versa. However, loft also has a very significant control over distance, with the key factor being the golfer’s selection of the right loft angles that will generate the most optimal launch angle for the shot to carry its maximum distance for the swing speed and swing mechanics of the golfer.

 

What is Moment Of Inertia (MOI) Matching?  

 

 

  The MOI of any object is a  measurement of its resistance to being placed in motion. Related to golf clubs, if each club in a set requires a different amount of  force to swing the club (set it in motion), it stands to reason that the golfer cannot be as consistent  swinging each different club in the set, as if each club were built to require the same force to swing. In most simple form, this is what sets MOI matching apart from matching clubs to the same swingweight. Swingweight matching does not make each club within a set the same in terms of the amount of force required bythe golfer to make the swing and hit the shot. MOI matching does. However, because golfers can be quite different in their strength, tempo and swing mechanics, the right MOI must be identified and fit for each golfer to allow the concept to properly work. To determine the MOI of the "favorite club", as well as all other clubs to be matched, there are 4 required measurements. The swinging period is a time measurement that can only be obtained with the MOI Period Counter (shown here). The other three measurements are each club's length, total weight, and balance point.
