11. Next measure and record the distance from the outside edges of circle B
and C, see Figure 326 Ensure that the caliper is not seated on the small
bump of circle C.

12. Add the lengths derived from steps 10 and 11 (A-B and B-C) and then
subtract the width of circle B. Record this total as “GFront”
13. Measure and record the distance from the outside edges of circles E and
F. Ensure the caliper is not seated on the small bump of circle E. See Fig-
