An Outside Spring Caliper is a mechanical measuring tool used to measure the external dimensions of an object,
such as the outside diameter or thickness of a part. It is commonly used in metalworking, woodworking, and other
crafts to take accurate measurements and transfer dimensions between tools or workpieces. The spring mechanism
provides tension, allowing the user to finely adjust the legs of the caliper for precise measurements.

Applications

1. Metalworking and Machining:

   • Checking Diameters: Commonly used to check the
     outside diameter of cylindrical objects like pipes, rods, or turned
     components on a lathe.
   • Machining Tolerances: Helps machinists maintain
     tight tolerances during the machining process by taking quick
     comparative measurements.

2. Woodworking:

   • Measuring Thickness: In woodworking, it is used to
     measure the thickness of wooden parts or ensure consistency when shaping
     round or curved surfaces.
   • Turning Operations: Frequently used during
     woodturning operations to measure the diameter of turned pieces on a
     lathe.

3. Craftsmanship:

   • Handcrafted Items: Used by artisans and
     craftspeople to measure and transfer dimensions when creating custom
     pieces or duplicating parts.

4. Inspection and Quality Control:

   • Comparative Measurement: Used in quality control to
     compare the size of a finished workpiece to a standard or template.
