Figure 46: Check cable diameter
From the table in Appendix C, select the correct drill
bit size for the cable diameter measured above (the
drill bit should be 4/1000 in (0.1 mm) to 10/1000
in (0.25 mm) larger than the cable diameter). Drill a
hole straight through the end cap using the pilot hole
(smaller hole) as a guide and check it for burrs.
