If the clock has three places to wind with the key it is a quarterly chime unit. This means it is either Triple chime or Westminster only. In other words every 15 minutes it will progressively play part of the song. At the top of the hour it will play the complete song then strike out the hours.
So fastening it well is very important. The movement can have a pendulum or no pendulum but of course the pendulum is most popular. When a mechanical clock does not have a pendulum it has a balance wheel instead. This is a floating and rocking wheel on the top of the movement and operates more like a watch balance.
Mechanical Clock Kit Styles - Granddaughter or Grandmother clocks
Grandfather clock kits
This means the weights will hang on cables instead of chains, and plays choice of three songs. However it is not always triple chime because some are Westminster only. This is the largest and tallest of the floor clocks.
All of the above mechanical clock kit styles, in the past, have been made with every chime type. In other words there are all these various ways to make the clock play a song or make a noise.
There is the quarterly sounds that play a tune ever quarter hour, the most common of the songs is Westminster. Or there is the triple chime that includes Westminster, St. Michaels, or Whittington.
As for the other noise makers, we call them strike clocks because they only strike out the hours and usually bong once on the half hour. These include Gong strike (coil gong on the back or below the movement), Bell strike, or Bim Bam (sounds like its name, on two or three strike rods).
Mechanical clock-kit movement options
The following are the various options for Mechanical clock-kit movements to utilize in building a clock.
We offer complete kits at Clockworks, however we can't include them all as it would be overwhelming. It may be possible to alter any aspect in the clock kits that are available. Please call to let us help with kit modifications or for general assistance.
Mechanical clock-kit movement options - Floor Clocks
Either Westminster only or triple chime. Both of these Mechanical Clock Kit options play a melody every 15 minutes and require a three weight movement.
Also there is the bell strike option that will play on the top of the hour whatever hour it is, and once on the half hour.
Options are the length, the bob diameter, and if would like a wood stick style The Pendulum or a fancy lyre style The Pendulum. The wood stick style is more antique look and the lyre is the contemporary style.
Either on the back for standard depth cases, or for the shallow depth we can do a side hammer unit.
Mechanical clock-kit movement options - Wall Clocks
Either Westminster only, Triple chime, Bim Bam, gong or bell. Lots of chime options there, but whatever wanted to listen to out of these we can do.
Includes the back, or on the side, or even the bottom on the wall clock kits.
Square dial made of heavy paper stock that uses a spray glue in order to attach it to a thin board, or a metal dial.
One style you can't get these days are the round dials that do lock into the movement, to have the appearance of the dial just floating in the air with the mounting hidden such as the Vienna regulator style.
Mechanical clock-kit movement options - Mantle or Shelf Clocks
Mechanical clock-kit movement options - Chime type
All of them really. an have Westminster, triple chime, gong, bell, or Bim Bam strike for Mechanical clock movement kit options.
Mechanical clock-kit movement options - Pendulum
Options include metal rod to a decor for the kitchen style clocks are available, or a wood stick pendulum if the clock is tall enough. For the shorter mantle units it will be just a round bob that is usually adjustable for time keeping.
Mechanical clock-kit movement options - Dial
If the situation calls for this type of clock dial, may want to chase a different clock design to make, it is not often it works out well unfortunately. The shelf clocks are easier as it has a door that closes with glass in the front, rather than the round brass bezel with dial and glass all in one combination.

Clock kit before building the clock case
It may seem counterintuitive, but it is more common than you might think to put a lot of effort into building a luxury case only to realize that the necessary components do not fit inside. To avoid this frustration and potential financial loss, it is advisable to purchase the clock kit first. This will allow you to ensure that all the components fit properly before investing time and resources into the case.
Why order a clock kit before building
Moreover, measurements need to be correct for the clock kit to fit into the case.
This way it will be easy to measure the various parts of the clock kit such as the pendulum swing and dial. Having the luxury of the components being in the air before you makes it much easier to measure and is a wise decision.
Not all clocks are made
Many sizes of antique clocks dials are not made anymore. Grandfather clocks back in the day had large Clock dials with ships on them.
They most certainly are gorgeous but try to find another one like it. These are no longer available. This is the case with many others as well. This is yet another reason to buy the clock kit before building the case.
Alternate kit component availability
To sum up this topic on clock kits. It is wise to get the Mechanical Clock Kit before building the clock case. The best thing to do is set up the movement kit in the workshop. This way is easy access to visualize the size prior to installation.
Do not build a beautiful case before buying components for it. Purchasing all of the components first will give you the opportunity to measure them and ensure they will fit in the case. This will help you avoid the disappointment of designing a case that cannot accommodate your components.
Making a Grandfather-Clock Seat-Board
Making a Grandfather-Clock Seat-Board, which is the mount that the weight driven movement sits upon, is fairly easy.
Typical approximate dimensions
Additionally, many of the modern clocks have a seatboard that is 16 inches wide and is 2 and a half inches deep. However this varies depending on the clock case dimensions.
In the center of the mounting board is a hole that is 1 inch wide. It goes across the center of the 2 and a half inch deep seat board.
Putting it together
These are the screws with the rectangle washers. Of course, an easier method would be to mount two, three quarter or 1 inch square boards running parallel, which are 1 inch apart, across the inside of the clock case. This is really all a mounting board needs to consist of.
The only thing that has to happen is the movement is in the air with the chains dangling down in between these boards. The boards just can’t be so wide that the pendulum rubs it on the back of the movement.
With the movement mounting in the air, all that needs to be done is have the chime block mounted.
This goes on the back of the clock case. This enables the hammers to engage with the rods for the chime sound. Next hang the weights and pendulum. The final step is to lock the dial into the movement from the front.

Grandfather Clock Pendulum Information
All three components in centimeters make up that CM length in the drop down menu.
Pendulum length information
Why the CM length matters at all is because if the pendulum length is not near the CM length of the movement, the clock will not keep time.
So the gearing in the movement and the pendulum length works together to keep time around the specified CM length.
The bob width Options
Moreover, the CM length on the movement will indicate the length of the pendulum from the TOP of the movement all the way down to the bottom of the pendulum nut threads.
This is an approximate length that depends on other factors such as bob diameter and weight of the pendulum.
Basically if the CM is 94CM the pendulum itself will be about 35 inches tip to tip off of the clock, and the 114CM option would put this same measurement at approximately 44 inches.
Grandmother Clock Movement Kit-GMKIT5
This quality Grandmother Clock Movement Kit has a Westminster chime movement that progresses at the quarter hours. After the chime it will strike out the hourly count if it is the top of the hour.
It includes a phase of the moon dial, and a chime silence switch.
Slim Grandmother Clock Kit Size
This is a nice size that will work with a Grandmother clock case where there is not a lot of depth. Side strike hammers really reduces the minimum depth requirement needed.
The clock case would need to be able to accept the movements minimum space requirements as indicated on the picture.
The Pendulum Length Options
There are a few options for the length of the pendulum. The CM is the pendulum length from the top of the movement all the way down to the bottom of the pendulums rating nut threads.
So this measurement is the pendulum itself from tip to tip off of the clock, the leader it hangs on, and the suspension that the leader hangs on. All three components in centimeters make up that CM length in the drop down menu.
This is based on the smallest bob diameter, larger bob diameters will have a slightly longer pendulum length overall.
The Bob Options
The 'Bob' is the round disc at the bottom of the pendulum, it can be a variety of widths. To select the width of the bob, first measure how wide the waist of the clock is. The bob size selected should have at least two inches on each side to swing back and forth.
German made chain driven Westminster movement by Hermle will run 8 days on a single wind up. It comes factory oiled and ready for installation. The movement includes the chains, mounting screws and washers, the leader, the suspension spring, hand nut and moon dial gear.
There are two square shaped outer plates made of brass with the puzzle of gearing between them, and then it has the hammers on the back, 4 on one side for the chime and 4 on the other for the strike.
