Solid beginner tool

I am new to Guqin making and this set made the polishing process much less intimidating. Clear results and easy to use instructions implied by the design.

Smooth operation

The ergonomic handle makes long sanding sessions much more comfortable. No hand fatigue even after working on multiple instruments.

Good value set

Very useful tools for surface treatment. The ruler is accurate, though I wish it came with a protective case for storage. Otherwise, excellent performance.

Precision at its best

As a luthier specializing in Chinese zithers, I find these tools indispensable. The finish they help produce is mirror-like without excessive effort.

Essential for serious makers

The straightness of the sound ruler is impeccable. It helped me achieve a perfectly flat surface on my new Guqin before applying the lacquer. Highly recommended for professionals.

Great quality wood blocks

The polishing blocks have a nice weight and the curve fits the instrument body perfectly. The included sandpaper varieties cover all stages of smoothing.

5 FAQ

Q: Does the set include coarse grits for initial shaping?

A: The set focuses on fine to ultra-fine grits (240-2000) intended for surface treatment and polishing rather than heavy initial material removal.

Q: Can these tools be used on other string instruments?

A: While optimized for the Guqin's specific curvature and length, they can certainly be adapted for use on similar long-necked or flat-bodied string instruments.

Q: What is the accuracy tolerance of the sound ruler?

A: Our sound ruler is calibrated to within 0.1mm deviation over its entire 120cm length, ensuring precise surface leveling.

Q: How should I store the ruler to prevent warping?

A: We recommend storing the ruler horizontally on a flat shelf or hanging it vertically by the provided hole, away from direct sunlight and humidity extremes.

Q: Is the sandpaper on the blocks replaceable?

A: Yes, the wood blocks are designed with a clamping mechanism that allows you to easily swap out used sandpaper sheets for fresh ones.
