Outside Spring Caliper 0 – 190mm Range SERIES 984 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 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. 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. Craftsmanship: Handcrafted Items: Used by artisans and craftspeople to measure and transfer dimensions when creating custom pieces or duplicating parts. Inspection and Quality Control: Comparative Measurement: Used in quality control to compare the size of a finished workpiece to a standard or template.
