This is a large (20+" diameter) mechanical clock originally designed to be cut with waterjet. It could be cut also with a laser, if the right materials are used.
the only non-cnc parts are shafts and tubes that go over the shafts, and a few screws to bolt the front to the back.
the design is based on two different wooden clocks from http://www.woodenclocks.co.uk/the_clocks.html (Clock 1 and Clock 2). The wooden clocks don't have second hands, but I added one to my design.
The front gear on the right shaft is connected to the ratchet and pawl mechanism and can be used for winding the weight back up again.
I don't have assembly instructions for this.
If you can open the solidworks file (there is a free viewer), you can look at the parts to get the full BOM. the different shafts are available at somewhere like Mcmaster. the gears are designed to be press-fit onto the shaft sleeves. The hour, minute, and second sleeves all nest onto the central shaft.
I don't know how much weight has to be used for the pendulum or the main weight for clock power. Alternately, the escapement could be replaced with a motor, and an arduino or similar can be used to regulate the speed.
The pendulum was designed so that the center of mass is at the correct distance from the pivot to tick at twice per second.
