Most timekeeping problems can be solved with a
little bit of knowledge, and some persistence. Clocks
with pendulums are generally the easiest to work with.
Begin with the knowledge that a longer pendulum
results in a slower running clock. Conversely, a
shorter pendulum causes a clock to run faster. Start
with a period of observation, say 24 hours, and
determine how much time the clock has lost or gained.
Write it down, and then adjust the pendulum up or down
using the nut on the bottom of the pendulum. We
usually suggest one complete turn of the nut for each
minute of error in a 24 hour period. Reset the time
and check the clock again in another 24 hours.
Continue in this manner until you have achieved the
desired accuracy. Clocks with balance wheels are
a little bit more difficult, but they usually carry
markings to indicate the necessary adjustment. Much
smaller adjustments are usually the order of the day
with these clocks.(Back to Top)
Striking problems are usually of two categories.
One; the clock fails to strike entirely, or strikes
only for a short period after winding. This is usually
an indication of a worn and dirty clock and hence
requires professional attention. Two; the strike is
out of sequence with the hands. To correct this, we
must first determine if the half hour and hour are in
sequence. If they are not, start by moving the minute
hand forward to the next striking point, and
determining what the strike sounded. If the clock
strikes the hour on the half hour, rapidly move the
minute hand one full hour, stopping to allow the clock
to strike again. You should now have the hour
strike coinciding with the hour position. Next, count
the strikes at the next hour, then move the hour
hand, forward or backward, to the hour indicated
by the gong or bell. Lastly, now set the clock ahead
using the minute hand, stopping at each hour
and half hour, allowing the clock to strike, until you
reach the correct time.

Clocks are usually made to run for 7 days. There
are exceptions of course, the most common being 1 day,
or 30 hour clocks, and 30 day running clocks. The
important thing to do is to wind the clock fully
each winding cycle. Keep a firm grip on the key and
wind slowly and deliberately. If the key wobbles on
the winding stem, replace it at once with a new one of
the proper size. remember that a mainspring when fully
wound has enormous power, and can cause serious damage
if it releases suddenly. It is very rare for a spring
to break while it is being wound. Weight driven clocks
provide a visual clue to their state of wind. When the
weight is down, wind the clock. Again, slow and
deliberate action is called for.
If a clock fails to run for it's appropriate
duration, it is usually an indication of mechanical
problems or need for lubrication. Consult with us for
advice. One last thing: When leaving your home for a
period of time longer than the running duration of
your clock, stop the pendulum before you go, and
restart the clock upon your return. You want to avoid
having the clock run down in your absence.
