I have always found wooden gear clocks fascinating, and now that I have a CNC machine, I can make one! Well, actually most people cut the gears tooth by tooth with a scroll saw, but I am much less patient than those people. All of the gears for this particular design fit onto my Zen 7x7 bed, pretty much taking up every last bit of room at times...which is slightly unnerving knowing that you are literally millimeters from a crash.
Anyways, the design is Brian Law's "Clock 2" found here: http://www.woodenclocks.co.uk/clock2.html
Most of the clock designs are free PDF plans, but the DXF files cost a little extra. I went ahead and paid for them because I really didnt want to convert PDF to DXF, and just wanted to start cutting. Once this clock is finished, I plan on designing a new clock more suited for CNC milling. Ive attached a few pictures, but will add more as I make progress.
Using 1/4" Oak plywood (it looks nice and is cheap) I cut several 6x6 blanks. After determining the EXACT excents of my machine, I found the dead center of my workspace and drilled a small hole. I found the center of my 6x6 blank and centered that directly at the center of my workspace before adding the hold down screws. After that, it was easy to just plop in a new blank and hit "Go!" to make all the gears!
