I was looking on ebay when I came across this Congreve clock. The pictures were blurry and there was even a random black power cord dangling from the table and so I couldn`t even see if it was truly mechanical but I bid at a low price and a fantastic rolling ball clock arrived. Sadly it didn`t run and it was quite a headache getting it working again.

I managed to get the clock running after making a few extra parts and quite a lot of changes to the base.

The following videos log me working on the clock at various points. The first video was for me really – to record how it worked and for reference if I needed to look back. The second video shows the running clock. These are a fantastic clock to watch!
