A Spring Divider, also known as a Compass Divider,
is a precision tool used to mark, measure, or transfer distances between two
points, primarily in metalworking, woodworking, and drafting. It consists of two
sharp legs joined at a hinge, with a spring mechanism that provides consistent
tension. This tool is commonly used to scribe circles, arcs, or precise
distances on materials like metal, wood, or paper.

Applications

1. Metalworking:

   • Measuring Distances: Used to measure and transfer
     precise distances between two points, such as the spacing between holes
     or edges in metal parts.
   • Scribing Circles and Arcs: Commonly used to scribe
     circles or arcs on metal surfaces, often for cutting or machining
     operations.

2. Woodworking:

   • Marking Layouts: Helps woodworkers mark precise
     distances or create arcs and circles on wood surfaces, making it
     essential for layout work before cutting or shaping.
   • Transferring Measurements: Often used to transfer
     measurements from a ruler or scale to a workpiece, ensuring accuracy
     when cutting or shaping wood.

3. Drafting and Engineering:

   • Technical Drawing: Used in drafting and technical
     drawing to create accurate circles and arcs on paper, blueprints, or
     other technical drawings.
   • Dividing Spaces: Can be used to divide spaces into
     equal parts or to measure consistent distances in architectural or
     engineering plans.

4. Craftsmanship:

   • Fine Detailing: Utilized by artisans and craftsmen
     for intricate detailing, layout marking, and measurement transfer in
     custom projects.

5. Machining:

   • Setting Machine Tools: Often used by machinists to
     set distances on tools like lathes or milling machines when fabricating
     or finishing parts.
