Tuning flute pipes (flue pipes) in an organ clock (like Black Forest-style flute clocks or flötenuhren) with a small blower is a practical method for restoration or maintenance, especially for individual pipes outside the full instrument.
Organ clocks use small wooden (or sometimes metal) flute pipes that play melodies via a pinned barrel or similar mechanism. These are typically stopped (closed at one end) or open flue pipes, voiced and tuned similarly to small organ pipes but on a much smaller scale. A small electric blower (often a variable-speed micro or hobby blower, like those for airbeds/inflatables) allows you to test and tune pipes one by one without needing the full wind system or bellows.
Setup for a Small Blower
• Use a variable-speed micro blower (e.g., a small 12V or 230V fan blower) with adjustable airflow. This mimics the low wind pressure these small pipes need.
• Attach a…
It's a beautiful dial and surround, one of the typical styles for Sorg clocks. I haven't seen fancy hands like that. Usually hands on Sorg clocks are simple arrow pointers or moon hands. The hands on your clock fit properly, so I suppose they could be original.
