The spikes should always be driven home straight and at right angles
with the face of the ties. When the foreman in charge of the
track-laying work sees a spiker, when the spike is nearly home, strike
the spike head laterally, which is done to make it lie snugly to the
rail, he should at once check such imperfect work and put the man who
does it at other work. The foreman in charge of gang of spikers should
be experienced in this branch of the work, and by weeding out
imperfect workers, can soon get together a first-rate gang of spikers.
But no trouble will be experienced from carelessly driven spikes, if
the tie has the spike holes bored into it, before laying. This is
considered good practice, but rather expensive.
[Illustration]
For boring the holes quickly and accurately, a proper template should
be made, by which the ties are marked for the borers, who should be
provided with boring machines, by the use of which a hole, square with
the face of the tie is bored. The boring machines should be so
arranged as not to cut the hole beyond the required depth, which
should be slightly less than the length of the spike. The diameter of
the holes should be about 1-16 of an inch less than the thickness of
the spike. This not only does away with the spike tearing its way
through the timber and thus injuring its fiber to a great extent and
causing it to be much more susceptible to rot, but it is said to
increase the adhesion of the spike in hard wood ties at least 50 per
cent. But in order that the best results may be obtained, the spike
should be flattened on either side of the sloping point, which will
generally prevent it leaving the hole.
