23. Measure and record the distance from the outside edge of circle H to the
outside edge of circle I. See
Figure 385: Measuring distances from outside edges of H and I
24. Measure and record the diameter of circle H along the center line
between G and I. See
Figure 386: Measuring diameter of circle H
25. Add the lengths derived from steps 22 and 23 (G-H and H-I) and then
subtract the width of circle H derived from step 24. Record this total as
"Rear"
26. Measure and record the distance from the outside edge of circle C to the
outside edge of circle E. See
