This clock was designed in inches and is the largest clock so far. To see a comparison of the clock alongside clocks 1 and 6 go here
I have been asked many times if it is possible to double the size of the clocks without compromising their function and the answer is always yes as long as you do not change the length of the pendulum, as this controls the accuracy of the clock. This new clock is my attempt to produce a larger clock, nearly twice as big, and large enough to work in a large room.
Like Clock 1 it is an in-line gear train that makes it easy to hang on a wall rather than have it shelf mounted.It also has an extra set of gears to get the second hand to run in the right direction, something I never fixed in Clock 1, but works well in this design as it fills out the interior of this larger format design.
The biggest change has been to design the Clock from the ground up in inch's so all the shaft’s work out correctly for all those working in imperial measures. Gears never work out in round numbers though, no matter what unit of measure you use.
A completely new dial design has been made for this clock. It is a simpler design than clock 6 and has a much smaller files size for loading.
