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.
The construction book was written by Bill Smith and can be bought here:
