HELP CHOOSING YOUR CLOCK KIT:
Please get a pen and paper and write down your
options as you go along, after reviewing these questions and coming up
with a basic plan, call us and we will help complete the details and give you a
quote.
Would you like a Spring Driven
or a Weight Driven clock
kit?
A spring driven simply means the clock
has either one (for time only) two (for time, strike) or three (for quarterly
chimes and hourly strike) winders to wind up every 8 days. This means that
you wind it all the way up once per week and if you forget a day its ok
because there is a one day reserve. Being spring driven means there will be
holes in the dial to put the key into and the clock will have no weights
dangling from it. This style movement is available for mantle, wall or
grandmother clocks. A weight driven clock means the clock will have either
two weights (for time, strike) or three weights (for quarterly chimes and
hourly strike) and are used in floor clocks only such as a grandmother clock
or a grandfather clock. Each movement would have their own weight
specifications as to how much the weight is to weigh.
Would you like the movement to be a Coil Gong, BimBam, Westminster or Triple Chime?
Coil Gong is usually
used in wall clocks and sometimes mantle clocks, the movement would have one
hammer striking a gong shaped in a coil, with the hammer being on the back of
the clock. Bim Bam makes a sound like its name on the half hour such as "BimBam"
and on the hour it will count out the hours, such as if it is two o'clock it
will chime "BimBam BimBam". This type of movement can have the hammers on the
side of it or underneath it. These are used in both wall and mantle clocks. Westminster chime units play a tune every fifteen minutes and then on the
hour, after it plays its song, it will strike out the hours. This style
movement comes available for all styles of clocks, wall, mantle, grandfathers
and grandmothers. The hammer arrangement can either be on the back, bottom or
even side. Triple chime units are like Westminster as it plays
every fifteen minutes, but you have a choice of three songs to select from.
The three songs are Westminster, Whittington or Saint Michaels. Again, after
its done playing the song at the hour, it will then strike out what hour it
is. These styles of clock movements have the option of having the hammers on
the back or on the bottom.
Would you
like a Balance escapement or a Pendulum escapement?
A Balance escapement means the clock has no
pendulum, instead the clock has an oscillating wheel like a watch. This type
of movement is most popular in mantle clocks. A Pendulum unit is of course
just this, it has a pendulum that wig wags back and forth from the back of
the movement. This type of movement is used in all clocks, even mantle clocks
if the pendulum is short enough.
If a Pendulum unit, what style, length and Bob Diameter?
Pendulums for wall,
grandmother and grandfather clocks come in two styles, wood stick with brass
colored bob or completely metal with a fancy brass style. The metal pendulum
is called a Lyre and is brass colored with a fancy design on it. The pendulum
length on Hermle and Kieninger movement kits (the only two companies making
movements today) are measured from the suspension post of the movement all
the way down to the bottom of the threads of the rating nut. This measurement
is made in Centimeters and is stamped on the back plate of the movement. So
this measurement is not only the pendulum from tip to tip, but also the
leader that the pendulum attaches to, and also the suspension spring that the
leader is attached to. In this case to determine your desired pendulum length
you would measure from the top of where the movement is to be and go down
from there to the point in the case in which you would like the pendulum
length to end. If you provide this measurement to us in inches we can give
you the CM conversion. A bob is the round disk at the bottom of the swinging
pendulum. This disk is available in different diameters for floor clocks,
most people like the biggest diameter the clock will take unless they have a
closed waist on the clock in which the pendulum will not be seen. To
determine how Large of a bob diameter you need it will require the width of
the case on the inside where the pendulum will swing.
What Handshaft length would you
like?
Often the movement will come in two hand shaft lengths.
A hand shaft is the shaft in which the hands are set on and it is measured
from the front plate of the movement itself to the very tip of the threads
for the minute hand nut. Usually the options are 33.2mm or 53.2mm. What the
longer hand shaft would do is set the movement back further from the dial
than the shorter hand shaft, this would in turn also set the pendulum and
weights back further if the clock were to have them.
What hand style would you like?
We will send you hands that are the correct size
for your dial diameter but would need to know what style you would like. For
Hermle units the hands come in Spade or Serpentine shaped. For Kieninger movements the hand style comes in
serpentine only.
What is the style and
dimensions of the Dial you would like?
There are many dials for wall and mantle
clocks, we would need to know if you would like a square dial or round, gold
or white, Arabic or Roman numerals, and of course what size. If the clock is
going to be spring driven then we will hole punch the dial to fit the
movement you are using. As for grandmother clocks, dials usually are only
available in two sizes, 9 x 13 7/8 or 11 x 15 7/8 from the bottom to the top
of the hump on the top. There is a hump because there is the words Tempus
Fugit on the top, or there is a disk that will tell you the phase of the
moon, one or the other. They are usually available in Arabic or Roman and
only need holes punched in it if they are spring driven. Grandfather clock
dials come in one size only, this size is 11 x 15 1/2 and has a hump on the
top that has the phase of the moon disk. These dials come pre-punched for
cable driven units, chain driven unit dials do not have holes punched in it.
Would you like a Chain Driven
movement or Cable?
This question only applies to floor
clock kits. On a chain driven movement you would open the door to the case and
pull down on one side of the chain as to raise the weight on the other side
of it. The clock will run for 8 days on a full wind, so you would wind it
once a week but if you forget a day its ok because of the one day reserve.
For cable driven clock kits, you would open the top door to the case to get to the
dial (face of the clock) and put in a key crank to wind up the clock. This
would in turn wind the cables back up and raise the height of the weight.
Again this is done once per week with a one day reserve.
Hopefully you now have a basis for the clock
kit you need written down. Please call 888-200-7445 or email
