Kuykendall Golf assembles clubs optimized by applying physics equations. This is the only way clubs can be scientifically correct. A patent by Vance Elkins, Jr. issued in 1978 explains all the formulas in detail. The patent has reached its 20 year limit and now clubs can be assembled using science.

There are three ways to match clubs --

1. Every club feels the same when you pick it up by the grip and it hangs vertically. In this case all the clubs have equal weight, e.g., total mass is equal for all clubs. M = S mi.

2. Every club feels the same when you hold it out horizontally. In this case the balance points on the shaft from the butt end are equal for all clubs. The first moment of inertia is equal for all clubs. 1st MOI = S li * mi

3. Every club requires the same amount of torque to achieve a specified club head speed. In this case 2nd moment of inertial is equal for all clubs. 2nd MOI = S l2i * mi

The Reasons scientifically optimum clubs have never been offered to you --

1. No tour player has ever played a club assembled in this fashion and they still shoot great numbers in spite of equipment non-optimization. What could they achieve if they played with optimized clubs?

2. You purchase hype for big dollars so manufacturers have no reason to offer you optimum.

3. It takes several hours to assemble one club. Every component must be optimized to within one gram. Big manufacturers could never afford this.

Why is Kuykendall Golf offering optimized clubs?

There is a demonstrable difference from the very first swing of the superiority of optimized clubs. You hit the ball farther, and higher with greater consistently. My pride and reputation are assembled into every club made. Everyone gets optimum.

How can you tell if a club is scientifically optimized? Does it have the physics-optimized-weight-energy-ring (Power) installed on the shaft? If the answer is YES, you have optimized club.

If the answer is no, you do not.

Using copyrighted formulas, head, grip ,shaft, and power ring weight are all optimized. There is a bigger gram weight spread between heads than conventionally used. The formulas then specify the shaft length and the amount of weight to be placed in the grip and on the shaft (The Power Ring). If your clubs do not have the power ring, they cannot be scientifically optimized. It takes about 2 hours to make a single club. Every component must have the correct weight to within one gram. Both the head weight and the difference between head weight is different from traditional. This is proprietary techonolgy developed over the last three years. Most shafts, after cutting, must have weight adjustments made to them. All grips must have a specific amount of weight placed under the grip. The final assembly is the adding of weight to the shaft for The Power Ring. This is the correct way to assembly clubs.

Two assembly methods are used -- Optimum Feel and Optimum Distance:

Optimum Feel:
Clubs are balanced for total weight (all irons are the same weight - all woods are the same weight). Clubs are balanced for the 1st moment of inertia - static weight (all clubs feel the same when held at address). Clubs are balanced for the 2nd moment of inertia - swinging weight (all clubs feel the same during the swing).

Optimum Distance:
Clubs are balanced for total weight (all irons are the same weight - all woods are the same weight). 1st moment of inertia varies slightly (slight static feel difference). Clubs are balanced for an optimum second moment of inertia (allows optimum club head speed).

By optimizing the 2nd moment of inertia, I can allow you to hit clubs specific distances and up to around 7% longer. This means that I can give you exact distance between clubs and allow you to hit long irons up to 15 yards longer with the same swing feel.

Because the assembly is labor intensive, the prices charged must reflect the labor cost. The cost of the clubs are:

Irons: with steel shafts	$125 each
Irons: with Aldila 60 gm graphite shafts	$150 each
Woods: with steel shafts	$225 each
Woods: with Aldila 60 gm graphite shafts	$250 each

If you are a long hitter, you should consider both methods. If you are a short hitter, I would recommend the Optimum Distance method.

Shaft Lengths:

There are two shaft lengths used in assembly. One is for golfers who use the traditional overlapping finger grip and the second is for the ten finger hammer-palm grip. When assembled for the ten finger hammer-palm grip, the clubs will be between 1 and 2 inches longer. When you separate your hands, if you move your hand down on the shaft you lose between 1 and 2 inches of shaft length. The upper hand must be moved up in order to have the same effective shaft length from the head of the club to the right hand.

The following heads are used:

Irons:
IMA Heads (see Scigolf Full Swing page for photos)

Features
Blade size- The size most tour professional use. Easy to square at impact.	Curved sole- Shallow divot holes. Easy to get through tall rough.
Perimeter Weighting- Resist twisting from off center hits.	Low Center of Gravity- Designed to produce optimum trajectory.
No Offset- Designed for correct swing mechanics.	Cavity Weighting- Allows heads to be optimized to within one gram. Allows physics formulas to be used to specify correct head weights and shaft lengths.

Woods:
The woods are the latest low profile maraging metal face technology. (See Scigolf woods page for photos)

Features
205cc driver: Standard face Back to the correct size for maximum club head speed.	Low Center of Gravity-- Low Center of gravity get the ball airborne with ease.
Maraging Face-- Hard, strong metal face produces more energy transfer and the sound is incredible. Confidence grows with each stroke.	Fairway Woods-- Shallow face. * Get the ball airborne easily. * Get through the rough easily.

Traditional Club Design:

Traditional club designs work. However, they are not scientifically optimum. This means that your equipment is causing you loss of total distance, loss of exact distances and poor control of ball flight height. There are four major problems.

The four major problems are:

1. Head Weight: Clubs have been assembled for over a hundred years with the same head weights and head weight difference between clubs -- typically 7 grams between club heads.

Iron:	9	8	7	6	5	4	3
Head Weight (GMS)	282	275	268	261	254	247	240
Head Wt. Diff (GMS)	7	7	7	7	7	7	7

This limits shaft length and optimum weighting of the entire club.

2. Swing Weighting:

Iron	Head Weight	Length	Length 14"	Torque 14"	Swing Weight
	OUNCES	INCHES	INCHES	NON SCIENCE UNITS
9	9.93	36	22	218.5	D1
8	9.68	36.5	22.5	217.9	D1
7	9.44	37	23	217.1	D1
6	9.19	37.5	23.5	216.0	D1
5	8.94	38	24	214.7	D1
4	8.70	38.5	24.5	213.9	D1
3	8.45	39	25	211.3	D1

Swing weighting is the ratio of the head weight to the grip weight measured 14 inches from the butt of the club. It was started in the 1920's. It has no scientific relationship to a golf swing. It completely mismatches clubs. From the torque calculated above, you can see that longer clubs feel and swing different from shorter clubs. Golfers just got use to this feel and believed in it.

3. Frequency Matching:

Frequency matching is just an indication of shaft stiffness. If you get the "S" curve frequency, all the shafts have a different stiffness. The only thing stiffness affects is the height of ball flight. Stiff shaft have a low trajectory. Flexible shafts have a higher trajectory. Getting a set that has the right characteristics for you is virtually impossible using frequency matching. The only advantage of frequency matching is for quality control. The shafts are more closely matched.

4. Oversized Heads:

Scientific studies show that there are four major disadvantages to oversized heads--

• They are open at impact due to wind resistance.
• They take a very wide divot. Fat shot are worse than with blade size clubs.
• It is extremely difficult to get a ball out the rough. The head is too big to get through the grass.
• With drivers, the head is slowed down due to wind resistance. This causes loss of distance. If you put a smaller head on the same length shaft, you will hit the ball longer.
