Design Specifications

Driving or going train: 2 x 80 teeth wheels
1 x 30 teeth count wheel
2 x 8 leaf pinions
Timing train: 1 x 32 teeth wheel
1 x 30 teeth wheel
1 x 10 leaf pinion2 x 8 leaf pinions
Pendulum length: 14.09 inches (pendulum length measured from base of the pendulum spring to center of the pendulum)
Pendulum spring: As clock 1 NOTE: DETAILS NEED 






Pendulum bob: 50mm x 50mm tube weight approx 1 kilo
Pendulum rod: As clock 1 NOTE: DETAILS NEED
The wheel hangars: 240mm long round, and also flat
Electronics: As clock 1 NOTE: DETAILS NEED

The major difference in the construction of Clock 2, apart from the obvious fact that the pendulum length is shorter and beats at 100 beats to the minute instead of 60, is in the housing. I have used of moveable bushes and the system of turned rods and/or square or flat hangers which hang down from the top of the clock case and are bolted in place. These are moveable forwards and backwards.

Some Design Considerations

It will become blinding obvious pretty soon that my objective is not to attempt to compete with the Modern Harrison’s of this world, I simply do not have the engineering skills.
What I will attempt to do is to show you that the only person that you need to satisfy is yourself and that designs can be changed, I am doing it all the time. I can do this because I am not operating to somebody else’s plan but rather to an evolving idea that springs from my own mind. It is terrific really because you are never wrong.

So my advice is that if you wish to have a really accurate time piece, go and buy one of the Atomic clocks that are now for sale, or simply rely on your phone or computer. But if you want to build something that will keep you entertained for years, read on.
