waterjet clock rev 4

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.
