IOLAR® GOLF was formed in 2003, to develop technologically
advanced golf clubs. Our first project was the design
and production of a game improvement putter - the IOLAR® No.4.
Don Parr, a life-long golfer, is the founder and president
of IOLAR® GOLF. His designs are the result of years
of experimentation and study along with the research
of Richard Greig and Frank Werner, authors of How
Golf Clubs Really Work and How To Optimize Their Designs.
Greig was particularly helpful in identifying performance
enhancing features rather than those that are marketing-
driven gimmicks or insignificant.
IOLAR® putters are performance-driven
but also stress quality, precision , elegance and
a respect for golf
traditions. Our clubs are CNC machined to exacting
specifications and assembled with only the best components.
They are hand-finished and meticulously inspected before
delivery. IOLAR® clubs and components are made
in the U.S.A. The
IOLAR® name was chosen as a
tribute to golf's Gaelic history. It means "EAGLE."
The Science Of Putting
Putting is 40% of the game, but is quite unlike the
other 60%. First, it is the only shot that is never
in the air; second, it is not concerned with power,
spin, trajectory or shaping; third, it is the only
shot that requires precision as well as accuracy. Unfortunately,
putting has its roots in the 60%.
Early golf was played on surfaces that often required
a stroke similar to a chip, and the putters of the
day were designed as such with iron-like lies and a
fair amount of loft. This tradition has carried over
to the present day, even though greens now are more
like billiard tables than the old-time bumpy, rough
surfaces.
It was not too many years ago that golf instructors
suggested that a putt was really just the bottom portion
of a full swing involving the arms and the wrists.
Even today we see accomplished golfers and instructors
using this technique.
The modern game has finally
adopted a sound putting approach – the pendulum-like
stroke, but this has come from evolution rather than
from invention. The first equipment to actually promote
a pendulum stroke only arrived recently in the form
of the long belly and chest putters. However, these
controversial clubs are not suitable for all players
and are difficult to use on long putts.
The optimum putting system is
a combination of equipment and technique and has
simple goals: propelling a ball
along a smooth grass surface with highly precise direction
and distance in a consistent manner. These goals can
be ideally accomplished with a pendulum putter machine
that can be aimed precisely and set to a desired distance.
The pendulum swings on an exact vertical plane and
the distance is achieved by the length of the pendulum
arc. The force exerted is solely a function of mechanics;
the mass of the pendulum weight, the length of the
pendulum arm and the length of the arc. The arm must
be fixed at the top and have a rigid attachment to
the weight. Inconsistencies in the ball's direction
and distance caused by surface conditions can be mitigated
by changing the effective loft – the point at
which the pendulum weight strikes the ball relative
to its equator.
The question is: How can we
adopt this mechanical putter system for human use?
First, a variety of constraints
must be considered. The USGA imposes three: the lie
of a putter cannot exceed 80 degrees from horizontal
(it cannot be vertical as is the machine), the loft
cannot exceed 10 degrees and it must "look" like
a golf club. Other constraints are human factors: the
weight must be heavy but controllable; the club must
feel comfortable, look good and instill confidence.
The equipment design parameters
are: head and overall weight, lie, loft and length.
The design should also
promote good technique. Factors that are not important
include head center of gravity, so-called "face
balance," i.e., the position the head assumes
when the club is held horizontally, heel/toe weighting,
polymer face inserts and any other "attribute" that
a club may be advertised to have. A discussion of these
factors follows later in Common
Misconceptions About Putters.
There are certain other non-critical
features that may help to minimize human errors.
These include a rounded
leading edge to mitigate scuffing (a more serious problem
than off-center hits), alignment marks to help achieve
directional accuracy and proper positioning of the
golfer’s head, and an oversize grip to discourage
wrist flex.
Putting technique should imitate, within the constraints,
the pendulum putter machine. This includes establishing
a fixed point for the top of the pendulum arm (the
shoulders), a rigid attachment to the pendulum mass
(the club) with firm wrists and a pendulum arc as close
to vertical as allowed. Distance control is provided
by the golfer in the same way the putter machine does
- length of the swing arc and force applied by the
arms.
Because a putter cannot have the vertical lie of the
putter machine (USGA rule), the path of any putter
is not always on line during a stroke. The putter head
follows an elliptical arc and is on line only at the
tangent point of that arc. If the ball is struck at
any other point, the face will be open or closed. The
face opens slightly on the back swing and closes slightly
going forward. The amount of this open/close action
is dependent on the radius of the arc: the smaller
the radius, the greater the open/close rotation of
the head.* This radius is a function of the effective
lie of the putter which is the combination of the putter
lie angle, the angle of the arms and the amount of
wrist rotation or flex. The flatter the lie, the smaller
the radius becomes. Wrist action makes the radius
even smaller.
The radius may be considered
a measure of potential error in the line of the putt.
The principal design
feature of IOLAR® putters is to minimize this error
by promoting an upright pendulum stroke
*The standard lie of an IOLAR® putter is 13
degrees versus 20 degrees in conventional putters.
The resulting arc radiuses are, respectively, 22 feet
and 15 feet. Wrist movement can reduce the effective
radius to 5 or 6 feet.
Center of Gravity(CG) - If the horizontal
CG point on the face is located at the spot where the
ball is to be struck, the location of the CG point
behind the face is irrelevant.
Claims that a rearward CG point somehow reduces skidding
or otherwise helps are simply untrue.
Face
Balance - This is truly an "old golfers' tale"
misconception. The position the face assumes when the
club is held horizontally with the head free to rotate
merely indicates the position of the shaft relative to
the sweet spot of the face. The sweet spot is the point
on the face where the ball is struck without producing
torque regardless of shaft position.
Heel/Toe Weighting (high
MOI) - This is done to reduce the torque effect of
off-center hits. However, for
a reasonably skilled golfer, this is a source of negligible
error. This is an important feature in other clubs
but its adoption as an important putter feature is
overdone.
Anti-Skidding Claims - Claims that
a putter eliminates skidding are simply untrue, for
it takes a brief time for the friction between the
ball and the green to produce true roll. Skidding may
be minimized, however, by matching face loft to the
condition and speed of the green. Claims that a negative
loft eliminates skidding, usually demonstrated on a
billiard table, are particularly misleading. Negative
loft can produce down force on a ball, which on the
resilient surface of a green, causes the ball to bounce
up from the surface. This can result in distance and/or
direction error.
Scuffing - The misconception is
that minor scuffs don’t occur and, thus, are
ignored in club design. This is obvious in name-brand
putters with sharp or small-radius leading edges.
Face Inserts - Polymer face inserts
will give a putter a softer feel, but otherwise have
no effect on distance or accuracy. This is because
the putter head and ball are only in contact for approximately
.5 microseconds (1/2000th of a second). This is not
sufficient time for the face surface to alter the putt
in any meaningful way. A very soft face might have
an effect, but the USGA limits softness to prevent
this. The USGA limits face durometer measurement (hardness)
to Shore A 85, about the hardness of a balata ball.
