Category: American Clock Mainsprings
Many American antique clocks had mainsprings that were too strong when they were new. For many years, the so called “standard” mainspring size was 3/4″ by .018″ by 96″, and new mainsprings of this size will cause wear to the mainwheel teeth. In this section I give examples of better mainsprings to use for new replacements. It is best to keep the original old mainsprings in some cases, and I give examples of this, too.
