Here's something interesting in the world of gear cutting. The video is pretty self-explanatory.

The Hermle Quartz Chiming Mechanism

Image
One of the quality and trouble-free movements found in many of our clocks is the Quartz chiming mechanism by Hermle. These are excellent, accurate, and durable devices which are made in Germany and sound great too! The Hermle quartz movements are workhorses in the clock world, because they can provide premier sound and accuracy for many different kinds of clocks. The mechanisms also provide lots of options for how and when the clock chimes. Here's a diagram of the version of the movement which includes a moving pendulum: Setup instructions for this movement are very simple: 1. Insert batteries. Because of a special coating that Energizer brand batteries uses on their contacts which is not compatible with this devices contacts, it is best to use any other brand besides Energizer. Duracell or almost any other generic brand will work fine. If your clock starts chiming erratically, or (if so equipped) the pendulum stops, please install new batteries. 2. If your clock has a mo...

Setting a Hermle w1217 Quartz Movement

Image
Here's a great post from Instructables on how to set the time and chime on an old w 1217 Hermle movement. This German-made movement was a pioneer in bringing a "real-sounding" chime to a quartz movement. If your older clock has one of these movements, and it doesn't work, it's more cost-effective to replace it with a more modern mechanism. But, if you just need to set it, here are some good step-by-step instructions on how to do so. From Instructables : Top left are the STOP and START buttons. Three knobs along the left side are also buttons. A knob in the center sets the analog hands. Upper right corner has the Make (Hermle) and Model# (1217) Lower right is the battery compartment. - The STOP button stops the analog movement and resets all digital settings. - The START button begins keeping time after you're done setting the clock. - Knob 1 sets the time in the digital portion of the clock. Turn the knob to the number you wish to set and press it until you...

Set your quartz cuckoo with automatic night shut-off

Image
Our NEW Sternreiter quartz cuckoo, model #40QM has a more sophisticated mechanism with an automatic night shut-off. The older models had a light sensor switch, but the new models actually have a timing device which shuts off the cuckoo and the music during the nighttime hours. In order for it to function properly, the clock must be sequenced to the proper day/night setting. In order to do that properly, follow this sequence: BEFORE INSTALLING THE BATTERIES 1. Turn the minute hand clockwise until it points to 5:00am 2. Open the back cover and insert 3 batteries R14 in the battery holder (for best results, use Duracell or a generic brand - any brand OTHER than Energizer.) 3. From 6:00am to 9:00pm, the cuckoo will call the full hour on the hour. From 10:00pm to 5:00am the night shut-off should be in effect and the cuckoo will not call.
