Bill Smith - How To Make an Epicyclic Train Strutt Clock

This is one of the most interesting of all single train skeleton clocks ever conceived. First made by William Strutt, in about 1830, it has a number of interesting and extremely unusual features not found in other clocks. Its 8-day run, spring driven train is epicyclic (planetary gearing) and involves a ring wheel of 4-1/2″ ID and 5-1/2 OD teeth. The motion work is based on the Ferguson Mechanical Paradox instead of the normal 12 to 1 gear train.
