Calculating a clock’s Ideal Pendulum Period, The Sequel

In an earlier post I calculated the ideal pendulum period for the Korean clock by counting its wheels’ teeth (outer teeth) and pinions (inner teeth). This post is an update based on the errors I made while attempting to do the same for my second clock: the Ansonia kitchen clock.

What follows is a more detailed “how to” for calculating the pendulum period based on gear ratios.

Clock Repair 101: Making sense of the Time Gears

In my previous post I finished cleaning my junker clock, ending up with a jumble of gears and other parts. You may recall that when I disassembled this clock, parts sort of fell out willy-nilly, leaving me a bit fuzzy about what gears go where.  In this post, I figure out which gears are part of the Going (time) Train (gear set), and as a bonus I calculate the length of pendulum this clock requires.

Clock Repair 101: Disassembly / Destruction

In my previous post I covered the dangers of mainsprings, and bought the minimum of tools required to safely handle mainsprings. In this post I disassemble my junker clock.

Using my new mainspring clamps and Let Down key, I “let down” (unwound) the chime mainspring and time mainspring, following the process I’d seen in the videos: Continue reading Clock Repair 101: Disassembly / Destruction
