Colonial
needles fall into three categories determined by the
age of the instrument. Styles overlap somewhat within
these groups. It is important to retain the characteristics
of the needles to correspond closely to the instrument
for which the needle is being made. In most instances,
a maker's needle style and dimensions have been documented
and the replacement needle will be fabricated accordingly.
Various makers utilized patterns which remained consistent
throughout their career.
Most of the early needle hubs were solid brass with
the appropriate wing protrusions from the hub. The later
(1770-1800) hubs by the more significant makers had
steel pivots inserted into the brass needle hub which
gave much longer life to the needle hub.
Note: The instrument must be supplied to Colonial Instruments
to properly fabricate and fit the needle, fine-tune
the clearance, pivot, and to properly align the ends
of the needle to the compass’s needle ring.
