Wire
Loops.--Wire
is
often
bent
over
at
its
end
in
the
form
of
a
loop,
in
order
to
connect
with
a
turnbuckle
or
fitting.
These
loops,
even
when
made
as
perfectly
as
possible,
have
a
tendency
to
elongate,
thus
spoiling
the
adjustment
of
the
wires.
Great
care
should
be
taken
to
minimize
this
as
much
as
possible.
The
rules
to
be
observed
are
as
follows:
(a)
The
size
of
the
loop
should
be
as
small
as
possible
within
reason.
By
that
I
mean
it
should
not
be
so
small
as
to
create
the
possibility
of
the
wire
breaking.
(b)
The
shape
of
the
loop
should
be
symmetrical.
(c)
It
should
have
well-defined
shoulders
in
order
to
prevent
the
ferrule
from
slipping
up.
At
the
same
time,
a
shoulder
should
not
have
an
angular
place.
(d)
When
the
loop
is
finished
it
should
be
undamaged,
and
it
should
not
be,
as
is
often
the
case,
badly
scored.

Stranded
Wire
Cable.--No
splice
should
be
served
with
twine
until
it
has
been
inspected
by
whoever
is
in
charge
of
the
workshop.
The
serving
may
cover
bad
work.
Should
a
strand
become
broken,
then
the
cable
should
be
replaced
at
once
by
another
one.
Control
cables
have
a
way
of
wearing
out
and
fraying
wherever
they
pass
round
pulleys.
Every
time
an
aeroplane
comes
down
from
flight
the
rigger
should
carefully
examine
the
cables,
especially
where
they
pass
round
pulleys.
If
he
finds
a
strand
broken,
he
should
replace
the
cable.
The
ailerons'
balance
cable
on
the
top
of
the
top
plane
is
often
forgotten,
since
it
is
necessary
to
fetch
a
high
pair
of
steps
in
order
to
examine
it.
Don't
slack
this,
or
some
gusty
day
the
pilot
may
unexpectedly
find
himself
minus
the
aileron
control.
