What Is a 9 Tube Grandfather Clock?

The 9-Tube Grandfather Clock

The 9-tube grandfather clock stands out as one of the most majestic and mechanically impressive timepieces in the world of horology. If you’re considering building, restoring, or purchasing one of these stately clocks, you’ve likely encountered the term but may still wonder: What exactly makes a 9-tube grandfather clock unique? And why do collectors and clockmakers alike treasure it?

In this article, we’ll explore what a 9-tube grandfather clock is, how it works, what sets it apart from other longcase clocks, and what you need to know before purchasing parts or a complete kit.

What Defines a 9-Tube Grandfather Clock?

A 9-tube grandfather clock refers to a tall-case clock equipped with nine long, vertical resonating chime tubes, typically made of polished brass. These tubes hang behind the dial or in the lower case and produce a rich, resonant chime sound. The movement that powers these chimes is mechanical and weight-driven, often featuring a triple-chime function.

Unlike rod chimes, which produce sound via metal rods mounted on a block, tubular bells deliver deep, cathedral-like tones. Each tube corresponds to a specific note, allowing the clock to play elaborate chime melodies like Westminster, Whittington, and St. Michael.

How Does a 9-Tube Movement Work?

The 9-tube grandfather clock movement uses a mechanical gear train that coordinates with hammers to strike the tubes in a programmed sequence. Each tube resonates at a specific frequency. When the clock strikes, the hammer taps the correct tube, producing a powerful, sustained tone.

The most common configuration involves:

• Quarter-hour chimes that cycle through a melody in segments.
• Hourly chime followed by the correct number of hour strikes.
• Three separate melodies selectable via a switch or pull lever.

Because of the complexity of the movement, the mechanism relies on three weights: one for the time, one for the chimes, and one for the hour strike.

What Makes 9-Tube Grandfather Clocks More Desirable?

Collectors and clock enthusiasts value 9-tube grandfather clocks for their sound, craftsmanship, and historical prestige. Here’s why:

1. Superior Sound Quality: The tonal clarity and depth of tubular bells are unmatched. The resonance is fuller and lasts longer than with chime rods.
2. Visual Impact: The nine gleaming tubes suspended vertically add visual elegance and mechanical beauty to the case.
3. Mechanical Complexity: These movements demonstrate superior horological engineering, which appeals to experienced collectors and hobbyists.
4. Customization: Many 9-tube kits allow for customization of dial design, case style, and chime melody.
5. Prestige: Historically, these clocks signified status. Owning a 9-tube clock meant having the best available.

What Parts Make Up a 9-Tube Grandfather Clock Kit?

When you purchase a 9-Tube Grandfather Clock Kit from Clockworks, you’ll receive all the core components needed to build or restore a complete longcase clock:

• German-made mechanical movement (often Hermle or Kieninger)
• **Hammer assembly** matched to the movement and tube length
• **Dial and moon phase (optional)**
• **Pendulum, bob, and leader
• **Brass weights and chains or cables
• **Mounting hardware **

This professional-grade kit ensures correct alignment, tone, and mechanical operation right out of the box.

How Large Does the Clock Case Need to Be?

A 9-tube clock demands significant space. Your clock case must meet these basic requirements:

• Minimum height: 84 inches (7 feet)
• Depth: At least 14–16 inches to accommodate the tubes and weights
• Width: 18–24 inches depending on dial and pendulum clearance

Tubes are often 1.25 to 1.5 inches in diameter and vary in length. The longest can reach over 40 inches.

If you’re building your own case or retrofitting a vintage one, make sure the tubes can hang freely without obstruction. The case must also provide access for winding, adjustments, and maintenance.

Are There Common Issues with These Movements?

Because of their complexity, 9-tube movements require careful installation and occasional servicing. Some potential concerns include:

• Tube alignment: Improper hammer alignment may cause dull tones or missed strikes.
• Chime selection: If the selector is misaligned, the melody might skip or stall.
• Cable or chain slip: Weight-driven systems must remain in tension for smooth operation.

However, when installed correctly, these movements are built to last decades. Regular oiling, cleaning, and checking the suspension spring help maintain long-term functionality.

Who Should Buy a 9-Tube Kit?

You’ll benefit most from a 9-tube grandfather clock kit if you’re:

• A clockmaker or hobbyist with some mechanical experience.
• A collector restoring a family heirloom.
• A woodworker or builder designing a custom tall-case clock.
• A dealer looking to resell a completed, high-end grandfather clock.

This isn’t a casual beginner’s project—but it’s also not out of reach for a dedicated enthusiast. With the right tools and support, it can be one of the most satisfying projects you’ll ever complete.
