Jauch Motion‑Works Issues — Diagnosing Hand Slippage, Loose Friction Joints, and Quarter‑Hour Drive Problems
Jauch Motion‑Works Issues — Diagnosing Hand Slippage, Loose Friction Joints, and Quarter‑Hour Drive Problems
Introduction Motion‑works problems in Jauch clocks often show up as slipping hands, incorrect hand alignment, or failure of the minute hand to advance properly. The motion works is responsible for... Read more...
Seth Thomas 89 Escape‑Wheel Issues — Diagnosing Wear, Power Loss, and Tooth Damage in the Upper Train
Seth Thomas 89 Escape‑Wheel Issues — Diagnosing Wear, Power Loss, and Tooth Damage in the Upper Train
Introduction The Seth Thomas 89 movement is known for reliability, but the upper train—especially the regulating components—can develop wear that causes erratic running, weak motion, or intermittent stoppage. When the... Read more...
Quarter‑Chiming Snail Function — How the Snail Controls Chime Count, Lift Depth, and Quarter‑Hour Sequencing
Quarter‑Chiming Snail Function — How the Snail Controls Chime Count, Lift Depth, and Quarter‑Hour Sequencing
Introduction In a quarter‑chiming carriage clock, the snail determines how many lifts occur at each quarter hour. Its stepped profile controls how far the rack can fall, which in turn... Read more...
Fusee Wall Clock Basics — Diagnosing Power Loss, Chain Issues, and Upper‑Train Wear
Fusee Wall Clock Basics — Diagnosing Power Loss, Chain Issues, and Upper‑Train Wear
Introduction Fusee wall clocks use a cone‑and‑chain system to deliver even power throughout the mainspring’s run. When these clocks run weakly, stop intermittently, or show erratic motion, the cause is... Read more...
Chime Clock Basics — How Chime Trains Work, How the Sequence Is Controlled, and How to Diagnose Timing Issues
Chime Clock Basics — How Chime Trains Work, How the Sequence Is Controlled, and How to Diagnose Timing Issues
Introduction Mechanical chime clocks use a dedicated train to play a musical sequence at each quarter hour. The system relies on a rotating drum or wheel, lifting pins, hammers, and... Read more...
New Haven Clock Stops on Warning — Diagnosing Strike‑Train Drag, Lever Timing, and Power Loss
New Haven Clock Stops on Warning — Diagnosing Strike‑Train Drag, Lever Timing, and Power Loss
Introduction When a New Haven clock stops as soon as it enters warning, the cause is almost always friction, misalignment, or interference in the strike train. Warning is the brief... Read more...
Platform Escapement Problems — Diagnosing Balance Issues, Power Loss, and Hair‑Spring Faults in Small Clocks
Platform Escapement Problems — Diagnosing Balance Issues, Power Loss, and Hair‑Spring Faults in Small Clocks
Introduction Small mechanical clocks that use a balance‑wheel regulating system—such as carriage clocks and compact mantel clocks—depend on precise interaction between the balance, hair spring, and escape components. When the... Read more...

New Cuckoo Movement Installation — Aligning Lift Wires, Setting the Bird & Door, and Ensuring Proper Strike Operation
Introduction Installing a new cuckoo‑clock movement requires careful alignment of the bird mechanism, bellows lift wires, and strike components. Even small differences between the old and new movements can cause... Read more...
Cuckoo Clock Escapement Wear — Diagnosing Upper‑Train Friction, Pivot Damage, and Loss of Power
Cuckoo Clock Escapement Wear — Diagnosing Upper‑Train Friction, Pivot Damage, and Loss of Power
Introduction Wear in the regulating section of a cuckoo clock often shows up as erratic motion, weak pendulum swing, or intermittent stopping. These movements run at high speed in the... Read more...
Cuckoo Clock Bellows Not Operating Correctly — Diagnosing Lift Timing, Wire Alignment, and Power Issues
Cuckoo Clock Bellows Not Operating Correctly — Diagnosing Lift Timing, Wire Alignment, and Power Issues
Introduction When a cuckoo clock’s bellows fail to lift properly, sound weak, or operate out of sync, the cause is usually misaligned lift wires, incorrect timing, or interference from the... Read more...
Why Modern German Movements Wear Faster — Power, Materials, Lubrication, and Design Differences Explaine
Why Modern German Movements Wear Faster — Power, Materials, Lubrication, and Design Differences Explaine
Introduction Many clockmakers notice that some modern mechanical movements—especially mass‑produced German units—tend to wear faster than older American clocks from a century ago. Despite being more precise in machining, modern... Read more...
How to Disassemble a Fusee Movement — Safe Mainspring Let‑Down, Chain Handling, and Plate Separation
How to Disassemble a Fusee Movement — Safe Mainspring Let‑Down, Chain Handling, and Plate Separation
Introduction Fusee movements require special care during disassembly because of the chain, cone, and high stored power in the mainspring. Incorrect handling can break the chain, bend arbors, or damage... Read more...
