The attached document is a bit mathemati cal but might be of interest to anybody who wants to make a clock with a slightly unorthodo x pendulum.
The .pdf document explains the idea. The Excel spreadshe et takes away some of the pain if you decide to make one.

Please note that this forum will not allow you to upload an Excel spreadshe et directly so this file has been zipped to make it acceptabl e.

Thanks Art.

I have this cunning plan to make a version where the pendulum is construct ed as a triangle. Therefore there is no vertical shaft which must swing clear of the arbors running fore and aft through the clock. Some interesti ng possibili ties come out of that.

At present I'm trying to get my prototype MDF clock running sufficien tly friction-free. If and when it's working I'll put up some pictures of the clock and the DIY CNC router I've used to make it.

Thank you for your pendulum uploads.  I am anxious to try a few variation s and see how I can work them into clock designs.
