Cleaning and Adjusting a Cuckoo clock’s Musical Movement

I’m in the process of cleaning and repairing a family musical cuckoo clock. I’ve watched a lot of videos on repairing cuckoo clocks, and have disassembled, cleaned, and repaired one cuckoo movement, so I think I’m as prepared as I can be for working on the clock movement.

The musical movement is another matter. What follows is a detailed How To that captures what I learned, what to do, and what not to do.

Is that Cuckoo a 1-day clock, or an 8-day clock?

Because of the economics of cuckoo clock repair, you can easily find old, dirty cuckoo clock movements on eBay for a fraction of what a new movement costs. These movements come with no documentation, so you get to work out which chains, weights, and bellows (cuckoo whistles) are right for them.

In this post I calculate the run time (1 day vs. 8 day) of a cuckoo movement I recently bought, and the Links Per Foot of the chain it uses. These two numbers tell me what parts to buy to make a clock case for this movement.

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.

Loosening Antique glue Using heat

As I said in my previous post about the Ansonia Derby clock, it seems that long ago part of the upper gingerbread broke and the owner sawed off the rest, reducing the upper gingerbread to a simple arch. I’d like to create new gingerbread for this clock. To do that I need to unglue the original, cut remnant and glue my to-be-designed gingerbread in its place.
