| Arrow
Types
Arrow weight has a great deal to do with the
penetration qualities that are inherent in the broadhead.
That does not mean that a heavier arrow will always have better
penetration. An arrow needs to be "spined" to match
a bow. Most compound bows can shoot a lighter arrow than other
bows of the same draw weight and retain true flight.
If
you have ever watched an arrow as it is released from a compound
bow, you can see that the arrow will warp or almost buckle
as it is fired and then straighten itself out. So, the initial
thrust on a relaxed compound bow is not the value of the full
thrust to come. For this reason, the arrow released from a
compound bow doesn't need to be as stiff as a standard bows
arrow.
The
arrow is made up of five basic parts:
- Arrowhead
-- This is the part that hits the target and does the damage.

- Inserts/Outserts
-- This is the part where the arrow and the arrowhead are
fastened.
- Shaft
-- This is the body of the arrow.
- Fletching
-- These are the feathers which keep the arrow stable in
the air.
- Nock
-- This is the piece which holds the arrow to the bowstring.

Nochs
The proper fit of a noch is that when it is seated
on the string, the arrow will just hang from the string by
its own weight, but is on firm enough so the arrow will not
slide on the string.
There are four main materials used for the shaft portion
of arrows. They are wood, fiberglass, aluminum and carbon
or graphite.
Wood
Arrow Shafts
Wood is the original material used for making arrows.
Wood shafts were used by the earliest hunters and they were
also used as weapons. Finding quality wood arrows today can
be difficult. If you want to use wood arrows, you will need
to learn about weight, grain, spine and straightness. Wood
arrows will very a great deal in these attributes from one
arrow to another and from one set to another. Wood is however
a very durable material to shoot from a bow. It will take
some abuse from rocks and stumps before breaking or other
damage. If you plan to use wood, do your homework.
The wooden arrows used by archers for millennia have
been replaced by ones made from aluminum-alloy or fibreglass
tubing, and plastic fins have replaced feathers.
Fiberglass
Arrow Shafts
Light,
Precise; Easy to fit to draw length and weight. Difficult
to find, liable to snap
- 1939
- James Easton experiments with making arrow shafts out
of aluminum, rather than wood.
- 1941
- Larry Hughes uses aluminum arrows to win the American
National (archery) Championship.
Aluminum
Arrow Shafts
Greatest Range of Sizes, Weights; Light, More Precise,
Interchangable Arrowheads. Aluminum arrows are used by the
majority of hunters and target shooters today. The first aluminum
arrow was developed by Doug Easton. (Easton Arrows) Aluminum
arrow are extremely consistent in weight, spine and straightness.
Aluminum arrow are very durable unless abused. Fletching or
vanes are easily replaced when damages. These arrows come
in more than four dozen sizes. The reason for the range of
sizes (weight) is that each bow shoots (and shooter) certain
weights and lengths of arrows to obtain maximum speed and
efficiency. In addition, lighter weight aluminum arrows are
normally used for target shooting and travel faster. Heavier
arrows are most commonly used by hunters.
- 1983
- Easton develops the first carbon arrow shaft.
Carbon
Arrow Shafts (Graphite)
Durable, Most Precise, Light with Interchangable Arrowheads.
Carbon arrows are growing in popularity. There are two kinds
of carbon arrows shafts; pultruded and cross wrapped. Pultruded
shafts have grain that runs the length of the arrow. This
type required the use of outserts to prevent splitting where
the field point of broadhead attaches. Putruded shafts where
the first type of carbon arrow and had a reputation for splitting
when hitting a hard object like rock, trees or bone. Cross
wrapped carbon arrows are a bit larger in diameter but are
still less than 5/16ths of an inch in diameter. In general,
carbon arrows are very light weight. The cross wrapped carbon
arrows are tougher than the pultruded. Neither can be permanently
bent.
