Where you start will depend on imagination and knowledge of clocks and what is possible-or seemingly impossible - but which you want to prove otherwise. ( ) From the picture, the general shape and size of the clock were guestimated, alterations identified, a motive force selected-in this case a 1 rpm motor, after which the gear train was designed to fit.

But having received the question a number of times, I'll elaborate. Planetary gear ratio calculations This article also available in Spanish A question that I often get is how to work out planetary gears using the gear template generator Working out the tooth counts for planetary gears is actually not that complicated, so I initially neglected to mention how to do it. Some notes about gear design and this gear template generator This gear template generator generates shapes for involute spur gears.

The gear generator program that I created and sell doesn't need the scale calibration, and can paginate across many pages for larger gears.

Printing the gear templates To print the gear template, use the 'Print' button, instead of printing the web page from the browser. Use an ink jet printer I recommend using an ink jet printer. You can still access the old (pre 2015) Flash based gear geberator Getting the printout to scale correctly, avoiding cropping Different browsers print at different scales depending on browser type and printer configuration.
