Lesson 2/Learning Event 1
Wing dividers, Figure 24, have a steel bar separating their legs, a locking
nut for securing a rough measurement, and an adjusting screw for fine
Wing-type dividers are available in 6-, 8-, and 12-inch
An improved version of this type divider has one leg with a
removable tip so a pencil can be inserted.
a. Never use
b. Never pile these tools in a drawer.
c. Never force dividers and calipers beyond their capacity or setting.
d. Never use these tools incorrectly. For example, changing settings
by hammering instead of loosening a clamping screw or nut, bearing
down too hard when scribing with a divider, wearing measuring
surfaces unnecessarily by using heavy measuring pressure.
e. Apply a protective film of oil to tools, when not using them.
