Assembly Guide

Three Steps to Your Masterpiece

1

Build

Follow the illustrated manual to snap each laser-cut piece into place. No glue, no special tools — just carefully designed parts that interlock with precision. Take your time and enjoy the process.

2

Wind

Turn the spring mechanism on the base. The mainspring stores kinetic energy that drives the entire movement — the same principle that powered music boxes over 300 years ago.

3

Enjoy

Watch the mechanism come alive as the melody fills the room. Whether it is playing a Chopin nocturne or a classical waltz, every note is produced entirely by gears and springs.

Pure Mechanical Power

Crafted for Connoisseurs

Every component is engineered with precision and finished by hand. High-latitude basswood — dense, fine-grained, and naturally resistant to cracking — forms every structural piece. The result: a music box that plays reliably for years without batteries or maintenance.

Attention to Detail

Every Piece Tells a Story

The Grand Piano Silhouette

The Grand Piano Silhouette

The unmistakable curve of a grand piano’s wing shape is faithfully reproduced at half scale. The long, sweeping body, the elegant legs, and the distinctive lid profile create a striking 3D form that commands attention from every angle.

Working Lid & Interior Details

Working Lid & Interior Details

The hinged lid opens to reveal an interior that mimics real piano architecture — string plates, soundboard detail, and the music movement mechanism. It is a fully functional replica that doubles as a conversation-starting display piece.

18-Note Precision Movement

18-Note Precision Movement

The built-in 18-note mechanical music movement is the heart of this kit. Winding the spring drives the cylinder against the steel comb, producing a clear, full piano melody. Each winding gives you 3+ minutes of pure mechanical music.

Frequently Asked Questions

What does the 1:2 scale mean?
The 1:2 scale means this model is a precise half-size replica of a real grand piano. Every dimension — length, width, height, and interior details — is exactly half the original, creating an impressive collector’s piece.
Does the piano lid actually open and close?
Yes! The RK-MB07 features a functional hinged lid mechanism. Once assembled, you can open the lid to reveal the interior string plate, exactly like a real grand piano — a working detail that sets this model apart.
How many pieces are there and is it difficult?
The kit contains 223 precision laser-cut pieces. The assembly difficulty is rated 3 out of 5 stars — a rewarding intermediate-level project. The illustrated manual makes each step clear, and most builders complete it in 5–7 hours.
What melody does it play?
The RK-MB07 uses an 18-note mechanical music movement to play a classic piano melody. The sound is produced entirely by the steel comb vibrating as the cylinder rotates — pure mechanical music with no electronics.
Is the 1:2 scale really that large?
At 1:2 scale, the assembled piano measures approximately 380 × 220 × 180 mm — significantly larger than most other music box kits. It makes a dramatic display piece and is one of the most impressive ROKR models available.
Do I need glue or special tools to assemble it?
No glue or special tools are required. All 223 pieces are precision laser-cut and snap together using a friction-lock design. A small flathead screwdriver may be helpful for pressing in stubborn pins, but it is not required.
