Mainsprings for American 8 Day Clocks

Many American antique clocks with open (not in a barrel) mainsprings use a “standard” mainspring of 3/4″ wide and approximately 18 thousands of an inch thick. There is a lot of variation in these springs between manufacturers, and across clocks made by the same manufacturer. I will comment more on these variations later. In general, […]
