Essential Information About the Precision Square with Stop 100 x 70 mm
- Compact size 100 x 70 mm : ideal on the workbench for fine lutherie work, where a large square becomes cumbersome.
- Integrated stop : provides stable support against an edge and facilitates repeatable checks, without "floating" on the piece.
- Measuring and marking tool : verifies squareness and helps mark clean and regular 90-degree reference lines.
- Designed for the workshop : intended to secure sensitive steps (fitting, gluing, assembly) where an imperfect angle affects the entire instrument.

An Essential Tool for the Luthier, Serving Geometry
In lutherie, precision is not a luxury: it is the foundation of a well-tuned, stable, and pleasant-to-play instrument. The precision square is one of the workshop's "silent" tools, those used at every stage without necessarily thinking about them, but which guarantee alignment consistency and assembly quality. Thanks to its 100 x 70 mm size and stop, it naturally integrates into control operations on small surfaces, typical of the manufacture and restoration of string instruments.
Intended Uses and Audience for This Precision Square
This square is aimed at luthiers, bow makers, guitar makers, restorers, as well as demanding amateurs who want to work neatly on string instruments (violin, viola, cello, guitar, ukulele, double bass). It is particularly relevant for checking squareness of edges, marking reference lines before cutting, and fitting parts that must join without stress. The stop provides real comfort whenever repeated checks on multiple pieces or returning to the same reference during a repair are required.
Sound Quality
Although a square does not produce sound, it plays an indirect but essential role in the final result: controlled geometry determines the alignment of components, the quality of bearing surfaces, the regularity of glue joints, and ultimately the stability of adjustments. On a string instrument, small angle deviations can create unwanted tensions, complicate fitting, and make some adjustments less reliable. By securing right angles during manufacturing or restoration, this square contributes to a more coherent, comfortable instrument and a cleaner assembly.
