SNARE CABLE
- WHAT IT IS - HOW IT'S MADE
Proper education regarding
cable types and how cable is constructed is very important. State
agencies have been seriously lacking in this education resulting
in cable restrictions in regulation. Statements such as "modern
snares are made of multi strand steel cable", "snares
are made of either crucible steel wire, or alloy aircraft cable",
"snares are old style snares made of other material"
and false assumptions such as "single strand cable causes
edema - multi strand cable does not", "single strand
cable has a definite kink and multi strand cable does not",
"single strand cable will crush the wind pipe and multi strand
cable will not", "Snares can only be used one time","since
single strand cable is a good killing snare it will not be a good
restraining snare" have been used to regulate cable type
without verification. Some state agencies have adopted, in written
regulation, the use of multi strand cable only, while at the same
time, stating single strand cable is "considered" multi
strand cable verbally simply because they thought single strand
was multi strand. WHAT
IS WRITTEN IN LAW IS LEGALLY BINDING. "VERBAL CONSIDERATIONS"
ARE NOT LEGALLY BINDING.
Many state biologist have no experience with snares and rely on
information given by "snare makers" who use multi strand
cable. These persons are expected to be bias and prejudicial in
their information.
The following information
is in reference to the construction of specific wire strand and
cable types and their comparative relationship. These types are
1x19 Single Strand (stranded wire), 7x7 and 7xl9 Multi Strand
cable.
Two distinct process take
place before wire is formed into cable strand. The first process
is making ingots of metal alloy and rolling these ingots into
rod coils. The second process is drawing rod coils into smaller
diameters to make wire. The first is done at a steel mill while
the second is done at either a wire manufacturing plant or, in
some cases, directly at the cable manufacturing plant.

STEEL
MANUFACTURING - Making ingots and rod coils.
Steel Manufacturers use
a "Crucible" (properly called a converter) to Mix,
melt and purify elements and minerals which are poured into a
form to make ingots or billets much like a cement mixer mixes
sand, gravel and cement compounds to make concrete. With metal
alloy this is done with heat. These ingots or billets can be
considered "crucible" or converter formed.
While these Alloy ingots are still at high temperature they are
hot rolled into the shape of wire rods perhaps 30 inches long
and 1/8 - 1/4 inch in diameter, then coiled. These wire rods
are not crucible - they are hot rolled into shape. (click on

stock for making wire is Rolled Stock not Crucible Stock.

WIRE
MANUFACTURING
All wire for snare cable,
stainless, galvanized or non galvanized, is processed in the
same way
The ROD COILS are first
cleaned in solutions to remove surface impurities an then placed
in a WIRE DRAWING FRAME. The sharpened end of the coil is inserted
in the die block and attached to the draw roller of the die block.
The rod diameter is reduced and length extended. The rod is then
annealed to workable temperature and ran through another set
of draw rollers reducing the diameter again. This Continues until
the wire is reduced to its finished diameter and finally wound
on reels.(see drawing). ALL WIRE is DRAWN. Wire is NOT CRUCIBLE.
