Please view these information tabs for Building Mechanical Clock Kits.
Mantle clock kits are always spring driven and wound with a clock key. Moreover, it can come in a variety of chime types. Triple chime, Westminster only, bell strike, bim bam or gong strike. 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.
Wall clock kits may be spring driven or weight driven. There are more spring driven wall clocks in the world than weight driven. The weights are not light and it is a lot for a wall to hold. 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
Typically, granddaughters are spring driven with no weights. The grandmothers are usually chain driven. The chiming units have three weights. Any other strike style has two weights. It is a shorter clock overall than a grandfather clock.
Grandfather clock kits
Typically cable driven with three weights and triple chimes. This means the weights will hang on cables instead of chains, and plays your 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 be utilized in building a clock. We offer predefined 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 predefined clock kits that are listed. 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 you 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.
Either a phase of the moon style, or just the hump top that says Tempus Fugit. Or we can zip off any moon The Dial or TF dial to provide a very nice square metal dial for you with no hump on the top at all. Another option is to use heavy paper stock on a thin board, use spray glue to make it stay.
Mechanical clock-kit movement options - Wall Clocks
Either Westminster only, Triple chime, Bim Bam, gong or bell. Lots of chime options there, but whatever you would like to listen to out of these we can do.
Either the wood stick style or sometimes if its short enough, we can put a brass rod pendulum in. The Mechanical Clock Kit options brass rod pendulum is different than the metal lyre pendulum as its just a brass rod going straight down with out all the decor.
Includes the back, or on the side, or even the bottom on the wall clock kits.
Square dial made of heavy paper stock that gets spray glued to a thin board, or a metal dial. In Arabic or Roman numerals. The dial on a wall clock would be mounted to the wood trim that goes around the dial, not interlocking with the movement. One style you cant 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. You can 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
The hardest on the mantle units. To get a the dial with bezel with glass in convex or flat is ideal, however not always possible. If the situation calls for this type of clock dial, you 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 is important to order the clock kit before building the clock case. If the case is built before getting the mechanical clock kit it is possible the kit will not fit. This sounds crazy but it is more common than anyone may think. So before spending a lot of time and hard work on building a luxury case, take the advice of getting the clock kit first. It will save you a lot of frustration and money in the long run.
Why order a clock kit before building
To find or adapt a clock kit to the case is very difficult. The ideal dial or other parts may not exist in the size that the case requires. Measurements need to be correct for the clock kit to fit into the case. Always order the Mechanical Clock Kit before building the case. Having the clock kit set up on a stand while working on the case is ideal. 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 suspended in front of you to measure at will is a wise decision.
Not all clocks can be replicated
The size of many antique clocks dials just 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. If the dial is found, you will need to drill winding holes. This way it will have a hole to put the key or crank into. Chain driven clocks are the only style that does not need winding holes in the dial.
Alternate kit component availability
Clockworks offers a large variety of clock movements. However, when it comes to some components resources can get slim. This is why it is important to buy the clock kit before building the case. Clock dials are the hardest because there are so many shapes, sizes, and options available. Examples include round dials, square, hump top with no moon, and moon dials.
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. Nothing is worse than making a beautiful case only to realize there are no components that will fit it. By purchasing all of your components before building, there is less chance for error when making the case. They will be at your disposal to measure at any time during the building process.
Making a Seat Board
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
The hole is wide enough for the movement to sit on the board with its chains hanging down in the center. Then the seat board screws and washers can go up into the movement’s arbors on the bottom. 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
Grandfather clock pendulum information begins with the obvious discussion of length. The length of the pendulum on German units comes in a few CM options. German units measure the pendulum from the top of the movement to the bottom of the nut threads. The pendulum itself, the leader it hangs on, and the suspension spring that the leader hangs on. All three components in centimeters make up that CM length in the drop down menu.
Pendulum length information
To know how long the actual pendulum is, subtract 15CM from the options with the pendulum length. This will exclude the leader and suspension spring, and be the actual pendulum length from tip to tip off of the clock. This length can vary as if a larger pendulum bob is selected, the actual length of the pendulum gets longer. 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
A Lyre grandfather clock pendulum comes with either a 6 1/2, 8 1/2, or 10 1/2 inch bob diameters. The 'Bob' is the round disk at the bottom of the pendulum . 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.
Tall-Case Grandfather Clock Kit
Tall-Case Grandfather Clock Kit with a German made clock movement. It is chain driven with an 8 day run time on a single wind up. A stick pendulum for a more antique or shaker look or can be swapped out for a more contemporary metal lyre style instead.
The Ideal Clock Case
A nice clock case to build for this kit would be a taller case where depth is not a concern. What makes this unit tall is of course the pendulum length, the depth is pretty deep with the longer two inch hand shaft and rear hammers. All this makes for a nice tall case unit with variable width options. The width of the case would depend on the pendulum bob chosen, there should be 2 inches on each side of the pendulum bob at minimum for the pendulum to swing back and forth. It can have an open or closed waist depending on if you want to see the pendulum through a glass window or not.
Chain driven Westminster movement will run 8 days on a single wind up. It comes factory oiled and ready for installation. It includes its chains, mounting screws and washers, the leader, the suspension spring, hand nut and moon dial gear. It has 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.
A wood stick pendulum will come unstained so it can be stained like the case on the customers end. It is a simple design that is good for the rustic antique style look. Pendulum length is 116cm from the top of the movements pendulum post, all the way down to the very bottom of the pendulum rating nut threads. If you were to take the pendulum off the clock and measure it from tip to tip off of the clock it would be around 42 inches. This is based on a small bob diameter, if a larger bob is used the length will be slightly longer.
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, you need to 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.
Chimeblock will mount to the back of the clock case by the included hardware. It has 8 premounted, pretuned chime rods and an overall length of about 27 inches through the block.
Includes a Tempus Fugit style dial that is 11 x 14 7/8. The silver and brass tone dial has raised numerals. Tempus Fugit dial's hump top can be easily zipped off for a 11 x 11 dial instead, if needed.
Kit includes three polished brass tone weights that are 47mm in diameter. Weights are shipped complete with fillers already assembled. Please note, these are tricky to ship as upon shifting back and forth sometimes the end caps get slightly damaged or concave. If this is the situation just let us know and we will ship out new end caps free of charge.
