Such a condition will cause the aeroplane to lose its
directional stability and also to fly one wing down.
I cannot impress this matter of tension upon the reader
too strongly. It is of the utmost importance. When this,
and also accuracy in securing the various adjustments, has
been learned, one is on the way to becoming a good
rigger.
6. 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 far 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.
7. 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.
