This is "Leeds". The Leeds has to be the easiest clock in Masochist's Corner (it's only in Masochists'Corner--not because it's difficult--but because I am too lazy to write instructions for it. Anyone want to write them for me?) The Leeds only has three wheels and yet will run for a week on a wind! How is that possible? The two lower wheels are internally toothed. Can you see the teeth on that lowest wheel pointing inwardly? Internally toothed wheels and their pinions both turn in the same direction! That way all three arbors are turning in the correct clockwise direction. The lower arbor shows the hours, the center arbor the minutes and the top arbor carries the second hand.

This clock is amazingly quiet, too. In the video below you will see Lisa's trained fly buzz by and you can hear that the fly is louder than the tick of the clock! This is such a cool clock!

This is a better picture that shows both of the large interally toothed wheels. The dials are also easy to read. Just start at the bottom and read up. 2:46 And as a bonus, this is the most accurate clock I've ever built. It isn't even off by a minute a week. Lisa says that I've finally reached Wal*Mart quality with my clocks.

Look how incredibly simple this clock is! This is such a cool design!

Because of the size of those large internally toothed wheels, this plan is only available in dxf format. No paper plans are available.
