There are several websites for clock plans. A place to start would be a link to many sites. http://wooden-clockworks.com/Link.html Try Mark Headrick's pages in that list, also Gary's wooden clocks. There's enough in that list to keep you busy for about a year. It also leads to sites where they sell the plans. There are also plans you can download for free in DFX or DRW format. http://www.pathcom.com/~u1068740/dow...ale-clock.html
Hope that helps a little. At least something to get you started. That download is probably the one you will want for CNC cutting.
