The Reciprocating
Chronometer Kit
This is one of my favourite
inventions, as it turns the
really simple and mundane
task of telling the time on its
head! Why have a boring
circular clock when you can
impress your friends and
amaze your enemies with a
Reciprocating Chronometer?
As with all true steampunk
machines, the Reciprocating
Chronometer is over-
complicated, employing
several intriguing
mechanisms to display the
time on an hour dial that
doesn’t go all the way
around, with AM and PM
being mechanically
displayed through a lens. It
has a beautiful polished
wooden base, a brass
(coloured) body and
mechanisms, clear laser
engraved legends, a brass
chain, counterweights and
even a lens and spirit level!
Don’t have any doubts
regarding your ability to
assemble it, as it’s designed
to be straightforward to put
together. I’ve broken down
construction into a series of
easy to follow video
instructions - check them out
below. Alternatively they are
available fully assembled.
● The Reciprocating Chronometer is 205mm (8 ⁵/₆₄”) wide, 75mm (2 ⁶¹/₆₄”) deep
and stands 225mm (8 ⁵⁵/₆₄”) high.
● It uses a high quality quartz clock movement to accurately keep time.
● The clock movement requires an AA battery.
● You’ll also require some readily available craft tools, wood adhesive, a plastic
adhesive such as Superglue and some metallic brass spray paint.
The kit contains all 92 parts required for construction; laser cut acrylic
mechanical components, laser engraved legends, brass and steel fixings, wood
for the base, metallic 3D printed mechanism shafts and a high quality clock
movement. Also included is the beeswax wood polish, vinyl gloves, to help keep
your hands free of beeswax wood polish, and abrasive paper so you can achieve
a really good finish.
Assembly Instructions
In addition to your kit’s contents,
you’ll require a small flat bladed
screwdriver, a medium Pozidrive
screwdriver, a 2mm Allen Key, a
scalpel or similar craft knife, a pair of
pliers, wire cutters, some masking
tape, an ‘AA’ battery, some tissue or
rag for cleaning and applying the
polish and newspaper or similar to
protect your work surface whilst
painting.
To glue the wooden base together, I
suggest using PVA wood glue. To glue
everything else together, I’d suggest
using standard Superglue. If you don’t
want to use Superglue, you could use an
alternative as long as it sticks plastic.
You’ll also need Metallic Brass Paint.
I’d recommend using Plastikote
Metallic Brass spray paint; other
manufacturers such as Rustoleum
produce similar spray paints.

To enable you to successfully assemble your kit, I’ve produced a series of step by
step videos. Click on the links below to watch each video. I suggest watching
each relevant section before starting work - then watching and pausing each step
as you actually follow the instructions. Please let me know if you have any issues
or suggestions to make the kit easier to construct.
