While waiting for its case to be repaired, my craft-altered Ansonia Derby clock has been running on a test stand – off and on for quite a while. I noticed that every great once in a while the count lever failed to drop into the 8 o’clock slot, causing the number of hours struck to be incorrect from then on.

…or why you should learn to maintain your own clock.
So you’re looking at that clock in the antique mall window. Perhaps it’s a lovely old Sessions Black Mantel clock, with lion heads and metal arches. It runs, and it’s only $90, so you take it home.

The family cuckoo clock I’m working on is being capricious about when it decides to play the music, so I’ve built a test stand that will let me see what’s going wrong.
After looking through the wide variety of weight-driven clock test stands on NAWCC.org. I decided to build a floor-standing U-frame.

Once I had the eBay cuckoo clock cleaned, adjusted, repaired, and running, I put the hands on. To my surprise, the minute hand kept slipping, no matter how I tightened the hand nut that’s supposed to hold it in place. The solution to this mystery lay in a troubleshooting video from a cuckoo clock seller in the Black Forest.

A while ago I bought a beat up cuckoo clock on eBay, to practice cuckoo clock cleaning and repair. Its face was missing most of its numerals. In this post, I describe how to use a 3D printed template to glue the numerals on a cuckoo clock’s face.
