1/4 2 Fig 2. Checking concave (internal) radius with arc up to 180°. Also will check radius shown in Fig. 1 but not relationship of sides. 1/8 4 Fig 4. Checking convex (external) radius with arc of 90° or greater, or radii with sides as shown which would interfere with gage used as in Fig. 3. 1/8 1 Fig 1. Checking concave (internal) radius with 90° arc. Also checks if sides are tangent to radius and 90° to each other. 1/8 3 Fig 3. Checking convex (external) radius with 90° arc. Also checks if sides are tangent to radius and 90° to each other. 1/4 5 Fig 5. Checking convex (external) radius with arc of 180°; also less than 180° if sides of radius offer no interference.
