Below are the initial steps of disassembly and cataloging. Total parts
count was 339, about the same as what would be expected in a full sized three train tower
clock. Afterward everything is cleaned in the ultrasonic machine. The part shown in the
tank is the hour strike count wheel. Compare it's size to the full sized version of this
same part from a conventional Gourdin tower clock.
One interesting thing found during disassembly was the discovery of a complete inner
spring barrel inside each of the two strike barrels. Why this was done is unknown. Perhaps
a large enough spring to fill the outside barrel was unavailable?
A prior repair person had decided to etch many of the parts with identification.
Apparently oblivious as to whether one could see his 'handiwork' after the clock had been
re-assembled. Bad practice! The left hand barrel in the third shot had a myriad of
indelible fingerprints on it's end cap.
If one decides to lacquer the parts of a clock, it is necessary to mask off all areas
that need to be free from the lacquer. This is a laborious job, nearly as time consuming
as the polishing itself. However, if done properly, the beautiful finish will last long
after an unprotected surface has begun to dull. Often when a taper pin is present I leave
the pin in. This protects the hole from being filled with lacquer, altering the tolerance
for the pin, and allows only the portions that show to be covered, (1). Notice that
wheel teeth and pinions are covered (2 & 3). It is not necessary to have the tape
follow the tooth profile all the way to the root. Covering the surface and spraying on a
45 degree angle radially from the center will prevent the spray from touching the inner
tooth surfaces. Parts with holes have to be pegged, as in the 3rd and 4th shots. Notice in
the 5th shot I lacquer with the frame parts assembled. This allows a perfect fit in areas
that could effect proper wheel depthing if there was a layer of coating on both the frame
bed and the under the bearing block or frame plate foot. It's likely that this would not
be a problem, but why take the chance? On larger movements this is unnecessary. It takes
extra care to do larger built-up parts to get the spray everywhere evenly on the first
pass. The last shot shows the completed frame assembly. Notice I am using gloves at this
point. While technically unnecessary as the parts are lacquered I still want everything as
pristine as possible and after lacquering all parts are never touched by bare hands again.
