Kronos-XII: Mechanical wall clock

grabcad

A fully mechanical wall clock with an honest and transparent design-The gear teeth are the rightful property of Brian Law. It is his geometry and design. If you wish to purchase the files for these gears, please visit his website http://www.woodenclocks.co.uk/ . This clock is modeled after his Clock #13. Then scale them up by a factor of 4.2.- This is a fairly large clock, and the gears have been split into multiple sections to accommodate for 3D printers- Each 3D printed component should be able to be printed within the volume of 140mm x 140mm x 140mm- The wood is 1/4" MDF that can be found at many hardware stores- The bearing model is 625ZZ and they have a hole diameter of 5mm- The screws used are #6 tapping screws- The weight that should be added to the counter weights and the pendulum is still undecided and I will update this post as I experiment - I am working to manufacture the clock in real life and I will post updates on here upon doing so- Huge thanks to my teacher/mentor Mr. Anderson for assistance with the design, and Brian law for the geometry of the gears- Brian Laws website: http://www.woodenclocks.co.uk- Mr. Anderson's website: http://www.stlhive.com
