Harmo.
In amongst making much simpler bits for my wife's weaving and lacemaking I'm slowly working towards a finished design for an electric wooden clock. All the gears are wood and the whole thing is driven by a standard 5V USB wall wart with the precision of a quartz watch. There's a video here which shows an old prototype of the design which is actually locked to a GPS receiver and is therefore as accurate as any clock you can get! Regular readers will have seen this before.

Progress today has been held up by the need to upgrade my CamBam installation to the beta 64 bit version as the standard 32 bit version ran out of memeory trying to plan the trochoidal tool paths for 12 gear wheels (enough for two clocks) to be cut from a single 600x900mm sheet of plywood at once. There are still some other pieces to cut from the sheet but the gear's teeth alone are over 154000 lines of G-code. The one in the video used less code-hungry conventional cutting.
