Crafted from high-quality steel with a spring-tensioned design, these calipers provide smooth operation and reliable measurements. The double-ended design ensures efficiency, allowing quick comparisons without switching tools—perfect for woodturners aiming for consistency in their work.
7" Double-End Bowl Calipers
Ideal for larger turning projects, these 7-inch calipers help measure the external dimensions of bowls, vases, and spindles. Their extended reach makes them perfect for checking uniform thickness on wide or deep pieces.
4" Double-End Woodturning Calipers
Compact and precise, these 4-inch calipers are ideal for measuring smaller turnings such as pen blanks, finials, or delicate components where accuracy is critical.
6"/150mm Inside & Outside Calipers
This versatile 6-inch (150mm) caliper allows you to measure both internal and external dimensions, making it an essential tool for bowl turning. Quickly check the inner diameter of a hollow form or monitor the wall thickness of a piece as you refine it on the lathe.
Understanding Caliper Sizes: What Do 7", 4", and 6"/150mm Mean?
When choosing a woodturning caliper, size plays a crucial role in determining its functionality. Here’s what each size represents and how it affects your measurements:
-
7" Calipers – These are best for larger projects like bowls, vases, and wide spindles. The 7-inch measurement refers to the maximum span of the caliper, meaning it can comfortably measure external dimensions up to that range. Ideal for ensuring consistent thickness on deep or broad turnings.
-
4" Calipers – Compact and precise, these are designed for smaller-scale turnings like pens, finials, and intricate spindle work. The 4-inch measurement indicates the tool’s reach, making it perfect for delicate pieces where fine accuracy is required.
-
6"/150mm Inside & Outside Calipers – This caliper is dual-purpose, measuring both internal and external dimensions. The 6-inch (150mm) span determines how wide it can open, making it suitable for checking bowl thickness, internal diameters, and various turned forms.
Larger calipers provide greater reach, while smaller calipers offer more precision for fine details. Choosing the right size depends on the scale of your woodturning projects!
