TITLE
A Fishing Hook Structure Constructed From Light Curable Acrylic Resin And The
Method For
Making The Same
FIELD OF THE INVENTION
[O1] A fly or lure for fishing, the fly or lure at least partially constructed
from light curable acrylic
resin (LCAR) and a method of making the same.
BACKGROUND OF THE INVENTION
(02] Prior art flies/lures (fishing hook structures) are typically made with a
hook, to which fibers
or various materials are attached by means of thread or glue. The completed
structure is intended to
mimic a food source for fish and, when used by a skilled fly fisherman when
attached to the end of a
fishing line can often be successful in catching fish.
[03] Hooks, threads, fibers and other materials come in a wide variety of
sizes, shapes,
dimensions and other characteristics and are chosen to be combined according
to the desired result-
a fishing hook structure attractive to a fish. For example, if one intends to
tie a Dark Cahill Dry Fly
then they may choose a suitable hook such as a MustadTM 94840 size 8 to 10. A
suitable thread might
be black, a suitable wing may be woodduck flank, a suitable tail may be brown
hackle fibers, a
suitable body may be muskrat fur and a suitable hackle may be brown hackle
fibers. This fly
imitates the dark phases of the genus Ephemerella and also represents a number
of other early season
gray colored mayflies.
-1-


CA 02475476 2004-07-22
[04] On the other hand one may desire to tie a wet fly for example, a Leading
Coachman. Wet
flies are taken by trout and other fish for a variety of sub-surface foods. If
one were to tie this wet
fly they may choose a MustadTM 3906 hook, black thread and fibers including
peacock herl for the
body, brown hackle and slate mallard wing quills for a wing. Likewise, Nymphs
and Streamers may
be made using a hook, thread, fibers and other materials.
[OS] The term thread here is intended to include thread, wire, floss and the
like. The term fiber
includes quills, dubbing, hackle, dunn, chenille down, hair, tinsel, fur herl
and any other natural or
synthetic fiber substance intended to simulate: tail, wing, hackle, thorax,
body and/or any other
structure of fish food substance which the fly/lure is intended to imitate.
[06] Typical prior art flies and methods for tying them may be found in the
book entitled "The Fly
Tier's Benchside Reference to Techniques and Dressing Styles" by Leeson and
Schollmeyer O 1998.
[07] Typically a fly may include a fly wing, fly tail and a fly hackle formed
from fibers. Flies
typically also include a fly body which may also be formed, in part, from
fibers of various materials.
The body may include a thorax, abdomen, head and other body parts.
[08] In addition to the hook, thread and fibers, adhesives may also be used in
tying flies. These
adhesives, typically liquids or semisolids, achieve several functions. These
include one or a
combination of: adhesive to attach material to the fly, coating for durability
and appearance, and
bulk for shaping a body or other fly structure. For example, adhesives may be
applied to the hook
prior to wrapping the threads, during the thread wrapping or after thread
wrapping to help make the
fly more durable and the fly tying procedure easier. For example, the
application of the standard
lacquer head cement onto the shank, covering the length of it will help keep
floss from slipping after
-2-


CA 02475476 2004-07-22
the fly has been tied. Further, a touch of head cement to the final windings
at the head of a fly will
help prevent unwinding. For another example, in tying a nymph head cement may
be applied to both
the winding and the outer side of the wing case to help prevent unraveling.
[09] Beside the standard lacquer head cement, there are new adhesives
available to the tier. The
use of adhesives can help make flys/lures more durable with less thread wraps.
These new adhesives
include: "Superglue" (cyanoacrylate), epoxy, nail polish, contact cements,
water base cements,
double stick tape and regular adhesive lure tape. Superglue may be used as a
finish on a fly. It may
be used to attach foam popper bodies to the hook. It may be used with
accelerator to promote faster
hardening. It typically comes as a liquid and chemically cures.
[10] Epoxy is used as a coating and as material for forming a body. It is an
adhesive which will
attach to the shank of a hook and to which the fiber materials may be
embedded. Numerous fresh
and saltwater flies utilize epoxy resin as a coating or a body material.
Epoxies cure by adding a
catalyst and a base to form a chemical reaction that hardens the material.
'They will also form a
tough, smooth finish when applied to a tie and will fill in gaps. However,
epoxy flies need to be
rotated until cured to prevent sag. This may be done by hand, but a rotisserie
is much more
convenient.
[11] Epoxy substitutes such as hot glue and Soft BodyT~' may be used. Hot glue
can be used to
build bodies and/or attach material such as fibrous material. It is fed
through a glue gun which melts
it and then it quickly cures. It may be used to make egg patterns, molded eyes
or flat flies.
However, it can melt at high temperatures, such as may be found in the tropics
and in tackle boxes
exposed to the sun. Soft BodyT" is available from Anglers ChoiceTM and is a
pure water based
-3-


CA 02475476 2004-07-22
plastic resin for coating flies. It may be used like epoxy for thick coats on
flies, while thinner resin
penetrates natural materials better. It sets in about twenty minutes and cures
to waterproof in about
twenty-four hours. It is less toxic than epoxy.
[l2] Nail polish can be used for head cement. Thickened up nail polish makes a
satisfactory one
coat gloss with streamer heads. A coating of thick nail polish, for example,
for wrapping a hackle
may make for a durable fly.
[13] Various adhesives are available such as: Shoe Glo GoopTM, Zap A GapTM,
AquasealTM. These
are strong flexible adhesives. They are used for gluing on eyes or coating
bullet head flies for
durability. Silicon caulking may be used to reinforce fibers such as rabbit
hides. Silicon caulking
may also be used to coat fibers such as lambs wool.
[14] Contact cement works well for flexible bonds. For example, latex can be
used to glue down
wing cases.
[15] Water based cement may be thick or thin. A chemical reaction allows them
to set. They
typically take longer to set than solvent based cements.
[16] In addition to the liquid adhesives, that may, like epoxy, serve both an
adhesive function and
the function of forming shape or body to the fly, there is double stick tape
that may be used with
foam. For example, double stick tape is used to wrap axound the base of foam
before the foam is
tied down to the hook. It prevents the foam from being cut with the threads
and fuses it in place.
Adhesive lure tape may be used to cover heads and bodies of warm water flies.
It may be used to
cover a foam cylinder to make a popper or the side of streamers. It can be
used to form caddis,
dragon fly and terrestrial wings.
-4-


CA 02475476 2004-07-22
[17] Many of the adhesives, however, have a number of drawbacks. Some are at
least partially
soluble and when the fly gets wet, one or more parts of the fly may become
loose or rnay fall off the
fly. Some leave an undesirable chemical contamination or are difficult to work
with. Some of these
are difficult to work with because they set up too quickly or, on the other
hand, too slowly.
Chemically adhesives will cure under conditions not directly controlled by the
fly tier.
Cyanoacrylate glue (superglues) may set quickly. Certain epoxies may set
slowly. What is needed
is a material and method for making flies which will afford one or more of the
deficiencies of
present adhesives. Thus, it is the object of the present invention to provide
a composition that will
serve at least some of the functions of the present adhesives that are
available but will provide
additional advantages.
SUMMARY OF THE INVENTION
[18] Applicants have discovered a new material for use in making or producing
new flies, lures or
other fishing hook structures. This material has a number of advantages over
the prior art material
and adhesives. Applicants' material consists of an acrylic resin that has a
catalyst which will react to
visible light (preferably 250-500 nanometers), thus controllably curing the
resin when the resin is
exposed to visible light. The acrylic resin is available in liquid, honey, gel
or putty form. In gel or
putty form it is easy to shape the resin to mimic a body, thorax, head or any
other structure of an
insect or nymph. It has heretofore been used in dentistry. A typical light
cured acrylic resin (LCAR)
material is clear gel Triad~ used in dentistry, available from Dentsply of
York, Pennsylvania. LCAR
-5-


CA 02475476 2004-07-22
is available, that will cure to varying degrees of flexibility, from non-
flexible to flexible, such
flexibility based on differing polymer chains.
[19] Applicants' novel fly or other fishing hook structure may be formed using
a hook as a base
and LCAR either as a liquid, honey, gel or putty to form the body or parts of
the body. As a putty, it
may be hand shaped onto the shank of a hook in any desired shape. When shaping
is completed it
may be exposed to a light source, for example, a high intensity light source
such as that available
from a high intensity halogen or LED source for approximately 5-30 seconds per
millimeter
thickness in which it will cure from a putty to form a hardened resin (faster
if clear LCAR is used).
High intensity light sources are available from Rembrandt Den-Mat Corporation
as the "AllegroTM."
[20] The LCAR is typically stored in light proof containers and may be
refrigerated. It is exposed
to light when the fly tier wishes to use it, but while it is light sensitive,
there is typically sufficient
time to shape a body or the structure on the hook. That is to say, LCAR may be
exposed to ambient
light but will not set up and cure immediately under such light. Rather, one
can work with LCAR in
typical ambient light, such as a hobby workplace, without the LCAR curing.
However, when curing
is desired, a intense light may be placed close to the shaped object and
curing will be effected in a
few seconds.
[21] Thus, a major advantage to applicants' novel fly and fly tying method is
that, unlike chemical
curable resins, which have a preset timetable (based for example, on
temperature and other
variables) the fly tier may shape and reshape the putty or gel until the
desired shape is achieved and,
at that time choose to cure the resin by application of a high intensity
light.
-6-


CA 02475476 2004-07-22
[22] Further, applicants' LCAR, when used in a liquid or gel form may coat
flies such as prior art
coating is used, which coating will set and cure when subject to high
intensity light.
[23] Applicants' LCAR may be used as a liquid to coat the shark of a hook
before the hook is
wrapped with string and then it may be cured. Depending on the type of LCAR
used, this could
produce a fly that floats. LCAR may also be applied to the hook after the
shark has been wrapped
with thread. It may be used as glob to shape a body of a wet fly, which will
sink.
[24] The use of applicants' novel LCAR may cut traditional fly tying time by
up to 50%. LCAR
can have a variety of colors added and bonds irreversibly to itself even after
one application has
already been cured. Applicants' novel LCAR may be used, far example, to cover
painting, or
stickers which have been applied to previously cured LCAR, thus rendering the
artwork imbedded
and waterproof.
[25] Thus, applicants' LCAR, as a liquid, honey gel, or putty, has numerous
uses in the
manufacture, and finishing of flies and lures for fishing. It may be used as a
method of making
artificial flies and lures. In its simplest form, the method may comprise the
steps of providing a
hook, a quantity of LCAR and quantity of fibers. One would shape the LCAR to
the hook and attach
fibers to the shaped LCAR and then cure it by exposure to a high intensity
visible light. The shaping
and attaching steps are not necessarily done in that order. For example, one
may wish to attach
fibers to the shark of a hook either using liquid LCAR, a prior art adhesive
cement or no adhesive
cement at all (using threads, for example). Following the attachment of the
fibers to the hook or
base, the LCAR may be applied and shaped into any desired configuration, such
as a body, thorax,
head, ribs, etc. After achieving the desired configuration one may cure the
LCAR. That is to say,

CA 02475476 2004-07-22
LCAR may be used to supplement additional fly tying techniques wherever prior
art adhesives or
epoxy is used. The LCAR may be used either as an adhesive or as a body
material itself or a
combination of an adhesive and body material.

[35) Figs. 24 through 26 illustrate, in conceptual view, the methods for
adjusting specific gravity,
altering the appearance of LCAR and texturizing LCAR.
[36] Fig. 27 illustrates the preferred embodiment of using LCAR to either coat
a fishing hook or a
component attached to a fishing hook, or to attach an item to a fishing hook
structure, the fishing
hook structure preferably being at least partially coated with cured LCAR.
DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
[37] Fig. 1 illustrates a fly constructed partially with applications of LCAR.
The body of this fly
is bonded to the hook with a layer of LCAR. There is an application of black
nylon floss around the
LCAR body to give a striped appearance and the floss may also be coated with a
thin layer of LCAR
which may be textured. There are four fiber wings placed on the fly toward the
front and bonded in
place with LCAR. Then the head and eyes are constructed of LCAR in front of
hackle neck. This
LCAR also acts as head cement to stabilize the tying thread or floss.
[38) Fig. 2 illustrates a fly (streamer) formed by using synthetic white;
yellow and red fibers tied
in the traditional method. Here, the LCAR is used to finish the head and hold
the fibers down and in
a more natural position while in the water. This LCAR also allows the person
to paint or draw on
the head and then add a clear coating of LCAR to seal and protect this art
work.
[39) More specifically, Fig. I provides a perspective view of a fishing hook
structure 10, here a
fly. Hook 12 is provided and LCAR is attached or applied to the hook to form
some or all of a body
14. Body 14 may include a head I4A, a thorax 14B andlor an abdomen I4C. Wings
16 may be
-9-


CA 02475476 2004-07-22
provided as well as a tail 18 and/or a hackle 24. Here, floss or other thread
22 is provided to wrap
around the body to help mimic a form attractive to a fish.
[40] Fig. 2 illustrates the use of LCAR applied to hook 12 using a fibrous
material here,
illustrating a fishing hook structure, namely a streamer. Eyes 20 may be
created by magic marker or
other art material and, after application of the marker material to the LCAR
or other base, eyes 20
may be coated with, for example, LCAR. The coating will help prevent water
from washing away
the created eye material. Note in Figs. l and 2 that LCAR 30 may be used as a
part of the structure
formed on the fishing hook 12.
(41] While Applicants may use LCAR to hand form, at least partially, the body
or other structure
on the fishing hook, as by hand application or hand shaping, Fig. 3
illustrates the use of LCAR 30
for mass producing LCAR fishing hook structures.
(42] Fig. 3 illustrates a mold 26 that is capable of mass producing flies or
lures. Mass production
may be achieved by inserting putty, gel or liquid LCAR, into the mold, (here
through use of syringe
28). Body parts may be molded separately and then attached to a hook, or the
hook may be
integrated into the mold. LCAR 30 may be used alone or with a chemical
catalyst, in this
application or any other application set forth in these specifications.
[43] Fig. 4 illustrates a kit 32 for making flies or lures or other fishing
hook structures. The kit
includes LCAR 30, here a light proof container 31 of LCAR. Included may be a
light proof syringe
28 of LCAR and/or a light proof plastic pouch 32 of putty LCAR. The syringe of
the kit may be a
"black" syringe with a light proof barrel and nozzle (see Figs.3 and 4). The
kit may include a light
source 35 (see Fig. 10) such an LED light source, an incandescent or halogen
light source. The light
-10-


CA 02475476 2004-07-22
source for the kit may be a high intensity light source such as that available
from Den-Mat
Corporation known as the Rembrandt AllegroTM. The kit may optionally include
an assortment of
hooks. Finally, the kit may also include an assortment of fly tying or lure
accessories including:
fibers, quills, hackles, eyes, sparkles, color dye, floats, rattles, as well
as any other materials and
accessories set forth in these specifications. Applicants provide a kit to
package the aforesaid
elements for the convenience of the consumer. The kit may also include any of
the fly tying
materials set forth herein and/or any of the materials set forth in Figures 24
through 26.
[44] The specifications set forth herein may apply also to the field of
taxidermy. The 2003 edition
of VanDyke's catalog illustrates known uses in the taxidermy field of epoxy.
Many such uses of
epoxy in the taxidermy field may be achieved with the use of the LCAR (with or
without a chemical
catalyst) as set forth in the specifications. Indeed, the following figures
illustrate some of the uses of
LCAR in taxidermy. More specifically see Figs. 5 and 6 for a lion 50 and a
fish 60 illustration,
respectively, which shows potential uses of LCAR in taxidermy including:
sealing, coating (for
protection) and bonding the skin to the preformed prosthesis. In regard to
taxidermy work, the
LCAR may be used to seal around the nose, eyes, ears, mouth, fins, claws,
teeth, tongue etc., of the
animal and filling in cracks and crevices and coloring the same.
[45] It is noted that, with the appropriate light source, the chemical
reaction in LCAR is
substantially complete within 15-30 seconds of exposure to strong light. On
the other hand epoxy,
such as is used in prior art fly tying, lures and taxidermy, takes overnight
or longer before it is
substantially complete. The time saving achieved by substantially complete
curing in a few seconds
in the high intensity light of applicants' LCAR will save a substantial amount
of time.

[46] Figs. 7 through 23 illustrate some of the steps in making Applicants'
novel LCAR based
fishing hook structure 10.
[47] Fig. 7 illustrates the step of providing a hook 12, here held carefully
in the j aws of a fly tying
vice.
[48] Fig. 8 includes an optional step of wrapping at least part of the shank
of the hook with thread
22. Following the wrapping, as illustrated in Fig. 8, one may, optionally,
apply a coating of LCAR
to assist in bonding the thread to the shark or to coating the thread for
strengthening and protective
purposes as illustrated in Fig. 9. If this coating step is used, then curing,
as set forth in Fig. 10, is
provided by exposing the LCAR to a light source 35.
[49] Beginning with Fig. 1 l, the tying of a fly, more specifically a shrimp,
to fishing hook 12 will
be illustrated, but is only exemplary of Applicants' present invention. Fig.

attaching step wherein part of the tentacles of the head 14A of a shrimp are
provided, here as through
the use of fibers 34. Part of the fibers may be wrapped directly to the hook,
or to a base of the hook
created by the aforementioned thread wrapping. In any case, whether fiber 34
is attached directly to
the hook or to a hook base (in the form of, for example, threads) illustrated
in Fig. 9, thread 22 may
be provided to at least partially wrap the fibers to the hook structure. Fig.
12 shows the completion
of the wrapping step. Fig. 13 illustrates that LCAR 30 may be applied to help
attach, strengthen,
protect and coat the fiber 34. Fig. 14 illustrates curing of the LCAR using
light source 35.
[50] Figs. 15A through 15F illustrate the steps, optional, of preparing other
body parts or
components for attachment to the hook structure, here stalked eyes 36 (see
Fig. 16). A heavy gauge
nylon fishing line 38 is heated to form a pair of balls 38A and 38B at the
removed ends thereof. The
-12-

balls are then coated with a thick layer of LCAR to form a pair of round bulbs
3$C, which, before
curing, are flattened 38D as in Fig. 15C, against a flat surface. A marker 39,
dye or other coloring is
used to create eye art on flattened bulbs 38D, which are then capped and cured
with LCAR in the
step illustrated in Figs. 15E and 15F to protect the eye artwork from washing
out and for three
dimensional or optical enhancement. In Fig. ISF, curing is undertaken and the
pair of eyes 36, on
stalks, are ready as in Fig. 16 to be attached to the fishing hook or fishing
structure. This is
illustrated in Fig. 17, the attachment typically done with LCAR, subsequently
cured as set forth in
Fig. I 8.
[51] In Figs. 19 and 20, additional fiber 34 is provided, here to form a tail
and attached by curing
using LCAR, see Fig. 20.
[52] Figs. 21 through 23 illustrate the manner in which accessories may be
attached to the fly or
fishing hook structure to make it more attractive to a fish. This particular
accessory, by way of
example only, is a fly rattle 40, which is a small cylindrical glass enclosure
including one or more
metal spheres for bouncing back and forth and creating a "rattle" sound,
attractive to some fish. In
any case, the fly rattle is only one of a myriad of accessories beyond the
hook, body and/or fiber that
may be used to make it more attractive to the fish, and LCAR 30 may be used in
applying, attaching,
strengthening and protecting such accessory. For example, Fig. 21 illustrates
LCAR 30 applied to
secure fly rattle 40 to the fishing hook structure. Fig. 23 illustrates the
curing step.
[53] Typically, LCAR would have a specific gravity of slightly greater than
one. However, the
LCAR may be adjusted for specific gravity of the resulting fishing hook
structure, so as to help it
either sink or float. For example, Fig. 24 illustrates some LCAR to which
either tiny dry
-13-


CA 02475476 2004-07-22
microscopic glass beads 42 may be added, to decrease the specific gravity of
the resulting mixture
and produce a hook structure that would tend to float. On the other hand,
powdered silica 44 may be
added to the LCAR to increase the specific gravity to produce a fishing hook
structure that will sink.
[54] Fig. 25 is an optional appearance altering step wherein LCAR may be
combined with one or
more of the following: dye; "glow-in-the-dark" materials (such as strontium
aluminate added 25-
60% by volume to the LCAR}; glitter; or other material.
[55] LCAR may be "texturized" to give the surface of the LCAR a desired
texture and feel, as
illustrated in Fig. 26. In Fig. 26, four different texturizing materials may
be used, but there are
others known in the art. Fig. 26 illustrates of one or more of the following:
ground hair; sand;
feather (ground); or sprinkler. The texturizing material may be pressed,
wrapped, or sprinkled on the
surface of the LCAR prior to curing.
[56] Thus, applicants attach LCAR to a fish hook, directly, onto a fishing
hook that already has a
support base, for example cured LCAR and/or thread, traditional fly materials
or some other base.
[57] Fig. 27 illustrates the preferred method of attaching any of the items 46
disclosed herein to a
fishing hook that may have previously applied and cured LCAR 48. LCAR is mast
effective as
mechanical bonding and bonds well chemically to a previously cured layer of
LCAR 48. Because
the LCAR secures mainly by mechanical forces, it is important to cover around
the edges of the item
and to a base of previously cured LCAR. A bonding agent, such as Hydroxy Ethyl
Methacrylate
(HEMA), BIS-GMA or MDP may be used to attach LCAR to a non-LCAR material.
Thus, in
applying LCAR to a fishing hook structure, as shaped part of a body, used to
coat, attach or seal, the
user should be careful to at least partially encapsulate (or preferably
completely encapsulate) the
- 14-


CA 02475476 2004-07-22
hook, thread or other support base. LCAR adheres well chemically to an LCAR
base or other acrylic
resins. On other bases, partial encapsulation to obtain a mechanical
attachment is best or the use of
one of the bonding agents.
[58] Shaping may be done by hand prior to curing, especially if the LCAR is a
putty. A brush,
paddle or a bodkin needle may also be used to shape the pre-cured LCAR. LCAR
can be provided
as a putty or can be used in liquid form and a thickener such as fused silica
may be provided to
thicken it before it is applied to a fish hook or base and shaped.
[59) A chemical catalyst may optionally be used in the method of making
fishing hook structures
to be mixed with the LCAR to help chemically cure those areas that light can't
reach.
[60] After the LCAR has cured, it may be further shaped, as by grinding,
filing or sanding in a
post curing shaping step.
[61] At times it may be important, in fly tying or making a lure, to adjust
the items to a specific
gravity-less than one or more than one. That is, it may be advantageous to
have a lure or fly that will
sink or float. To achieve the ability to float, a foam material or other
material which is impregnated
or traps air may be used in connection with the LCAR to assure that the fly or
lure will float. On the
other hand, specific gravity of greater than one may be assured by the
addition of silica, for example
or with the addition of other materials with a specif c gravity of greater
than one to the LCAR,
typically prior to curing. The LCAR, referenced above has a specific gravity
of slightly greater than
one so, if used in connection with a hook, and without a material having a
specific gravity of less
than one, the fly or lure will typically sink.

[62] While disclosed in the specifications above, in some cases, flies for use
in fly fishing, the
method and compositions discussed herein, anticipate use in a lure for use in
salt or fresh water and
for custom construction or mass production of lures or flies.
[63] Used as a liquid, LCAR may be used to pour into molds. Used as a gel or
putty it may be
hand shaped for the body or even used as an adhesive for an attachment of
accessories to itself
previously applied a hook or to a body of a fly or lure. That is to say,
Applicants' LCAR may be
used in a range of viscosities from putty to gel to honey to liquid. Liquid
LCAR is available from
Ultradent Products as Permaseal. Silica or other additives may be added to
increase the viscosity.
[64] Besides the quick set and cure upon exposure to a high intensity light
source, there is no
waste or messy mixing required with LCAR, especially when used without a
chemical curing agent.
There is no waste, offensive aroma or messy mixing with LCAR.
[65] Fly tying materials may include one or the more of the following: thread,
fibers, fur; feather;
foam and cork; hooks; synthetic fibers including hair and flash; natural hair;
soft plastic; tubing (e.g.
mylar tubing and/or flexicord); eyes, including synthetic eyes (e.g. lead
eyes, adhesive eyes and doll
eyes); rattles; rubber legs; dubbing; chenille; tinsel; latex and cords of
nylon, vinyl or other plastic;
and beads. While it is understood that this is a list of "fly tying materials"
and that these
specifications use the term "fly tying," Applicants' invention covers more
than flies. Indeed,
Applicants' novel method and devices include adorning a hook with a shape
attractive to a fish.
Such a shape could and may include (but are not limited to) the following
shapes: an insect;
amphibian; birds and rodents; mice; eggs; crustaceans; and minnows.

[66] Other fly tying materials include dyes that may be used to dye other of
the tie flying
materials. Further, Applicant's LCAR may be used as a substitute for or in
conjunction with epoxy,
silicon, and other materials to create durable bodies, and eyes. Applicant's
LCAR may be also used
in conjunction with thread, floss and yarn. LCAR may be used in conjunction
with traditional prior
art methods of tying flies, to create a fly, lure or other fishing hook
structure that is part LCAR and
part epoxy, for example.
[67] Applicant's LCAR may be applied to hook structures including lures.
[68] Optimally, Applicant's novel method uses light cured acrylic resin.
Acrylic resin with the
photo initiator responsive to electromagnetic radiation preferably in the 250-
550 nanometer range is
preferable, and more preferably in the visible blue light range, most
preferably about 470
nanometers.
(69] LCAR also provides for an effective substitute to epoxy in the process of
building a fishing
rod. Fishing rods may be built using prior art method and accessories except
using applicants' photo
initiated setting and curing of LCAR as disclosed herein.
[70] One example of the use of applicants' of LGAR in building a fishing rod
would be to set the
guides in place and expose them to high intensity light source when they are
properly positioned. A
mold for use in "mass production" for flies or lures would typically be made
of clear plastic, so as to
let light penetrate for the curing step.
(71] Although the invention has been described with reference to specific
embodiments, this
description is not meant to be construed in a limited sense. Various
modifications of the disclosed
embodiments, as well as alternative embodiments of the inventions will become
apparent to persons
-17-

skilled in the art upon the reference to the description of the invention. It
is, therefore, contemplated
that the appended claims will cover such modifications that fall within the
scope of the invention.
