Free plans to help you build a wooden clock. The plans on this site are those of
clocks designed by myself over the last few years. At present there are eight sets
of plans available, and it is intended to add to them as new designs become available.
Each clock design is illustrated with a series of rendered images, and a set of drawings,
drawn to scale and presented as PDF files. The earlier clocks were originally drawn
to scale so that the prints could be attached directly to the timber and a band saw
or scroll saw used to cut around the profiles. Now it is more common to use some
form of CNC machining to produce the gear profiles, so the DXF files for the clocks
are now available and in some cases the 3D model files as well. These enable the
clock builder to not only simplify the construction but also to increase the accuracy.
The original clocks are still available for free but as the new clocks appear I will
make a small charge for the files.
The site has undergone a complete overhaul for its 10th anniversary, to try to get
it cleaned up a bit and make it easier for you to find your way around and for me
to update it more quickly. I hope to be adding new clocks on a more regular basis
now that I have more time to devote to it. There are three projects on the horizon
plus thoughts on an off shoot to the site that opens up the opportunity for me to
work on a wider range of mechanisms that can be equally rewarding for the those who
enjoy this type of project.
I hope you find your visit to the site rewarding and if you have any comments or
suggestions please contact me.
DXF files available
If you require the DXF files for any of the clocks on the site then go to the page
for the clock that you require where you will find the DXF files listed along with
model files for the newer clocks. The files can be used either to produce Gcode so
that you can machine the profiles on CNC machine or it can be used for your own design

Free DXF files
If you want to try a sample of the DXF files for a test on your CNC machine then
this small assembly is ideal. It has 2 gears mounted onto a base strip with the centre
positions set so that the gears mesh correctly. The file has some dimensions in dual
metric and imperial formats so as to allow you to check the correct import into your
system. The holes and pins are Ø6 mm but can be drilled out to 1/4” if you are working
The sample is of course free, simply click on the image to download.
To read the PDF files you will need Adobe Acrobat reader so click on the image below
to install it on your computer.
Three of the clocks 3,7 and 8 on the site are all built from the bottom up in inches,
so if you have trouble with metric these are the clocks to go for. I have bundled
the plans and the DXF files for these together and I am offering them for $20.
This is the most compact clock I have designed with a short pendulum having a period
of oscillation of 1 second, that is a ½ second swing in each direction. This required
an extra set of gears in the train, to achieve the correct ratio for the escapement.
The unit is hung on the wall by a special hanging bracket that allows the clock to
be easily mounted.
The front of the clock has a door to which the dial is fitted, this can be opened
to better view the internal mechanism.
This clock requires that the case be turned on a lathe or machined in 3D, so could
be more difficult to build for those who don’t have the equipment. To help with this
I have included the 3D data in with the drawings and the DXF files.
The clock was designed in metric units but is dimensioned in both metric and imperial.

To carry a new range of plans and files devoted to the mechanisms devised by Leonardo
da Vinci. There is one model on the site at present, it is a cannon called a Spingarde
designed by Leonardo, and it brings together several features used in cannon at the
time, but never in one device.
It requires standard model making skills to produce and you should be able to complete
the build in a shorter timescale than some of the clocks on these pages.
Do go to the new site and have a look around and please let me know if you find it
interesting and what other Leonardo inventions you would like to see there.
Clock 3 has been missing from the site for some years now, and it is only now that
I have been able to complete it and put it on the site
Clock 3 was designed to be a replica of a typical 15 th century Verge and Foliot
clock, but it never got finished and was replaced with the more ornate design for
Clock 4. I have resurrected it here with some small refinements, it is a much simpler
design than the others on the site.
This clock using the verge and Foliot was never very accurate, hence the use of only
the hour hand. It wasn’t until the introduction of the pendulum that accuracy was
improved, in fact many original clocks were modified with a pendulum to improve the
accuracy, so very few examples remain.
The clocks movement is controlled by the oscillation of the Foliot backwards and
forwards controlling the the release of the escape wheel as the paddles on the verge
move into and out of engagement with the pins on the escape wheel.
Accuracy is poor because of number of features that have a bearing on the movement,
chief amongst these is the main weight followed closely by the weight and positions
of the Foliot weights.
It is a familiar looking design because of its existence over many centuries, so
enjoy building your own replica and feeling a connection with craftsmen over the
Three of the clocks 6,9 and 10 are probably the most challenging to build, so I have
bundled the plans and the DXF files for these together and I am offering them for
$20. Go to any of the clock pages to find the offer.
Clock 11 is the second new clock this month, and has been designed in response to
a number of requests for a simple clock design that could be made by a first time
I have tried to do this here and although the clock is simpler it is still going
to take dedication to see it through.
The design is simpler as it only uses 6 gears, by comparison Clock 1 has 12 gears
and Clock 7 has 14.
A further change to reduce the number of gears was the introduction of a pull cord
that is wound opposite to the weight, so by pulling down on this cord the weight
is lifted back up.
I have also tried to reduce the size at the same time so that the largest parts can
be fitted onto a small router table. I don’t really know what that minimum size is
but the largest piece on this design is 277 mm tall so can be fitted to a piece of
A4 paper, or Letter size paper if you live in the US.
Actually the Dial is slightly too large to fit an A4 sheet so you would need to stick
two off set copies together to do that.
Last year I introduced Projects for gears , which gave you a selection of gears to
use in your own projects, this year it is the turn of mechanisms, There are 6 sizes
of Geneva mechanism. An inverted Geneva mechanism, a couple of rotary to linear convertors
and a couple of Intermittent motion devices.
These are packaged as DXF and PDF files, along with image files and videos to explain
I have put an new clock on the site, it is a completely new design, that will stand
on a fire place or cupboard, without the need for a hanging weight. It is designed
to use a spring to provide the motive force, and has a compact pendulum to swing
within the height of the clock. The clock is small designed to fit onto the smaller
CNC machines and measures 350 mm (14 inches) tall and 190 mm (7.5 inches) wide.
I have just completed building the prototype, you can see the result on the videos
on You Tube shown opposite.
Most of the work has gone into designing and developing the spring drive using a
standard spring from clock suppliers.
The prototype has been built using a variety of materials and techniques to reduce
friction and ensure that the spring has the power to drive the clock.
Another change from the normal is the inclusion instructions on how to to build the
clock, not instructions for making each part, help full instructions for putting
the clock together and getting it ticking
I have been asked several time if the clocks could be built using 3D printing techniques,
and up until now the answer has always been, not advised, as the parts are really
too big and expensive to build that way.
This clock is designed to be built using Stereo lithography.The sections have all
been reduced to a basic 1.5mm thickness all over.
The SLA parts have a total calculated volume of 87 cc, and a calculated weight of
There is a minimum of metal parts that are needed for strength and function. These
are basically the shafts, bearings and the brass weights.The suspension used to
hold the pendulum at its top end can be obtained from any clock parts supplier.
Clock 14 is another compact spring driven wind up mantle clock, unlike Clock 12 this
is not a minimalist design but uses a full gear train to drive the hands and has
a very open construction to show off all of the gears .It is again quite small standing
316 mm or 12.5 inches tall, and dimensioned in both metric and English.
The clock runs for about 20 hours on a single wind, but as with all the spring drives
the accuracy can vary but if its wound every 12 hours it will keep time to within
a couple of minutes over the 12 hour run.
The drawings and CNC files are available for download along with renders of the models
and instruction for building the clock.
The prototype has now been completed and can be seen in the video on Youtube.
The grasshopper escapement is an unusual, low-friction escapement for pendulum clocks
invented by British clockmaker John Harrison around 1722. I have modified the design
so that it can be readily cut from flat timber using either a scroll saw or CNC.
It is presented as a demonstration piece so that it will function as an escapements,
but not connected to the rest of a clocks gearing. You can make it as a demonstration
piece or include it into your own clock designs.
It is shown with brass weights embedded in the arms to give you the correct working
balance without needing to incorporate any adjustment means.
Two versions of the design are available, a compact conventional arrangement and
a more elegant variation.
In the Summer edition patterns for the wooden gear Clock 11 are published along
with test cutter Rolf Beuttenmuller description and video of his build of the clock.The
patterns have been adapted from the original design of Clock 11 available on this
Clock 11 is probably the simplest of my designs as, it requires less gears to be
cut, but is still a fully functional timepiece and an excellent introduction to the
making of wooden clocks.
The patterns and instructions provided by the magazine are excellent and will be
sufficient to enable you to cut out all of the components to build the clock.
For more background on the original and to get the DXF files if you want to build
this with your CNC router go to the Clock 11 page.
Clock 15 is the first clock design to use the Grasshopper type escapement . Developed
originally by John Harrison as a means of reducing friction in the escapement, it
is a more complex and intricate design that require more accuracy in the making,
but rewards by being quieter and more interesting to watch. I have tried to reduce
the original complexity by removing much of the adjustment used in the original,
so if the plans are followed carefully it should work pretty well ‘out the box’.The
clock is styled after the Art Nouveau period and as such has flowing natural lines
and curves reflecting that of nature.
