MEASURE USING CALIPERS AND DIVIDERS
DIVIDERS
In setting a divider to a dimension on a scale, the usual procedure is to
locate one point in one of the inch graduations of the rule and to adjust
the nut or screw so that the other point falls easily into another inch
graduation, Figure 25, Part A.
NOTE. Do not set the point to the end of the rule.
This could cause an
inaccurate measurement.
Make certain the points of the divider are not blunt, Figure 25, Part B.
FIGURE 25.
USING DIVIDERS (A, B, AND C)
When transferring a dimension from a part or tool to the scale on a rule,
use the same care in adjusting the points of the dividers. Make sure there
is no excess pressure. Excess pressure tends to spring the points either in
or out.
Figure 25, Part C, shows a mechanic scribing a radius on a die
block he is laying out.
