I've got RhinoCad but have just dabbled with it. I'm not familiar with ccycloid. Is it a plugin for Rhino? When I get back on the mando, I'm just going to use a digitizer probe that came with my ShopBot to get a profile for roughing the plates. I'd like to eventually get the ShopBot set up to do the headstock veneer with peg holes and binding/inlay slots the way Dudenbostel does them. Anybody else here doing that sort of thing? - Pat
