5) Regulating the clock
The pendulum keeps the clock running at a constant pace. The position of the bob on the
shaft determines how fast the clock runs. If the clock runs slow, move the pendulum bob
higher. If the clock runs fast, move the pendulum bob lower. As you adjust the bob, make
sure you keep the bob oriented vertically so the clock’s beat is not affected. Patiently
adjusting the bob over the course of several days should result in the clock keeping
reasonably accurate time. Expect your clock to gain and lose time with changes in
temperature and humidity. Also, expect your clock to require a “break-in” period of a week
or two during which it may not be as consistent as it will in the future.
6) Winding the clock
Wind the clock by pulling downward on the rewind pull or rewind cord with your left hand
while simultaneously lifting the weight with your right hand. It will take some practice to
get the feel for this. Verify that neither cord has jumped off of its pulley. If necessary,
restart the pendulum after winding. The clock should run for over 30 hours on one winding.
7) Final gluing
The friction fit of the set washers is purposely looser than the gears to permit easy
adjustment. Once the proper position of set washers has been established, they can be glued
onto the arbors if desired. The gears ought to be tight enough on their arbors to not require
glue. However, if needed, they can be glued at any time in the future. Do not glue the
following pieces: the two set washers on the front side of the great wheel arbor, second
hand, hour hand, and minute hand.
