9. Adjusting the pendulum
The length of the pendulum determines the running speed (timekeeping) of your clock. The
longer a pendulum the slower is its swinging speed. To change the running speed, move the
pendulum bob up or down and, thus, shorten or lengthen the effective length, that is the
distance between center of gravity of the pendulum and pendulum hook. The pendulum bob
can be moved up and down by turning the adjustment nut. Depending on pendulum type, this
adjustment nut is above or below the pendulum bob.
Before you make any change, observe and note the timekeeping of your clock over a longer
period of time, for example 12 or 24 hours.
9.1 Lyre and Wooden pendulums
The adjustment nut is located below the pendulum bob.
Turning the adjustment nut as seen from above counterclockwise will shorten the effective
pendulum length and the clock will run faster. Turning the adjustment nut clockwise will
lengthen the effective pendulum length and the clock will run slower (picture 14 - see page 26).
The correct adjustments for your clock can be found in the chart on page 47. Please make sure
that the pendulum bob remains fully seated against the adjustment nut and pull it down as
needed.
Remember to reset the time after adjusting the pendulum bob.
9.2 Compensation pendulum (option)
The adjustment nut is located above the pendulum bob.
Turning the adjustment nut as seen from above clockwise will shorten the effective pendulum
length and the clock will run faster. Turning the adjustment nut counterclockwise will lengthen
the effective pendulum length and the clock will run slower (picture 15 - see page 26).
The correct adjustments for your clock can be found in the chart on page 47. Please make sure
that the adjustment nut remains fully seated on the cross bar and pull the pendulum bob down
as needed.
Remember to reset the time after adjusting the pendulum bob.
