W. F. STANLEY & CO. LTD.
MANUFACTURING PRINCIPLES AND PROCESSES
Stanley theodolites and levels and other instruments, are made
throughout at the Eltham Factory passing through the following
departments :—
FOUNDRY, where considerable importance is attached to the composi
tion of the castings that are used. The alloys are the result of many years
of experiment and experience to determine the best mixtures for each
particular purpose. Every precaution is taken to avoid inclusion of impure
metal, and porous or defective castings are never used.
MACHINE SHOP, where processes of milling, turning and drilling by
modern machine tools are carried out. Tubing has been discarded wherever
possible in favour of castings ; for instance, in telescopes, which are cast
bored and broached to assure perfect alignment of the optics. As many
components as possible are cast in one piece to ensure simplicity, stability
and reliability.
DIVIDING DEPARTMENT. Here the most precise machines are em
ployed. Machines which are used in dividing, from the simplest ring of
the Prismatic Compass to the glass circle for the most expensive Theodolite.
ASSEMBLY DEPARTMENT. In this Department instruments are as
sembled by highly skilled male labour, and components receive a second
examination to guard against assembly of defective parts.
ADJUSTING AND TESTING DEPARTMENT. Here are employed
craftsmen of great skill, adjusting and testing to the highest standards of
perfection.
INSPECTION. Before leaving the Works all instruments undergo a
very thorough and systematic examination in this Department which,
for this purpose, is equipped with special testing apparatus, to ensure that
“ Stanley ” instruments are second to none in quality and performance.
