What are the different types of radius gauge?

There are 7 different types of radius gauge:

These include the 2 radius gauge sets: A and B.

A. Gauge with single function blades at either end.

B. Gauge with multifunction blades at either end.

C. Gauge with 5 measuring surfaces.

D. Acrylic gauge.

And gauges: F and G.

F. Digital gauge.

Gauge with single function blades at either end

There is a blade for measuring concave surfaces at one end.  At the other end there is a blade for measuring convex surfaces, both blades correspond to the same range of measurements.

Gauge with multifunction blades at either end

Each blade is capable of measuring a concave and convex surfaces as part of the multi-functional internal and external blade design. Each blade has an inscribed measurement which refers to both concave and convex applications.

Gauge with five measuring surfaces

This radius gauge has five cut out projections which can be used for measuring both (2) concave and (3) convex surfaces. It is also used for scribing precise radii on to work pieces.

Acrylic gauge

Acrylic radius gauges are capable of measuring concave and convex radii. They are commonly used in woodworking processes such as turning spindles, duplicating mouldings and rounding corners.
