Bell Maintenance Examination in Series - Initial Evaluation
In the world of antique and vintage clocks, a 170-year-old Scottish tall case clock has caught our attention. This historic piece, recently won at auction, is now undergoing a meticulous restoration process.
The clock's English bell strike movement, a common feature in tall case clocks from the mid-19th century, presents a unique set of challenges. With 170 years of operation and exposure, delicate and worn components such as the hammer, bell, gearing, and striking mechanism are showing signs of wear, corrosion, and possible metal fatigue.
One of the most pressing issues is the misalignment or sticking striking parts. The hammer or strike trip can become misaligned or sticky due to accumulated grime, rust, or mechanical wear, causing the bell strike to malfunction or not sound at all.
Weight and pulley problems are another concern. If the weights and pulleys are original or old replacements, ropes or cables might be frayed or replaced incorrectly, leading to malfunction in the striking train or the clock stopping unexpectedly.
The movement's sensitivity to incorrect setup is another factor to consider. For example, if weights are strung too high or incorrectly replaced after moving the clock, the striking mechanism may jam or not operate properly.
Worn wheels, pinions, or pallets can cause wear-related timing issues, making the strike off-beat or incomplete. The fragility from mixed heritage parts, in this case, a Scottish case paired with an English movement, can also pose unique fitment or adjustment challenges.
Accumulated dirt and old lubrication can cause sluggish operation, necessitating thorough cleaning and re-oiling with proper clock oils. Potential part replacement or repair may be necessary due to age, with careful restoration or crafting of replacement parts to maintain function and originality.
The item in question also requires some structural work, and the overall finish is dull and lifeless. The rack tail, a component that takes a beating during the strike sequence, is damaged and requires repair. The missing seconds hand and disconnected calendar hand are issues to be addressed.
Interestingly, the movement has no calendar function, but the face has a calendar hand. This is a common issue with antique tall case clocks and can be rectified during the restoration process.
Tall case clocks have dropped dramatically in price over the past few years, making them more accessible to collectors and enthusiasts. For those interested in following the progress of this restoration, you can subscribe to get the latest posts sent to your email.
