摘要： A method (400) includes drilling a first aperture (146) in a panel (22) that extends between a panel first surface (48) and a panel second surface (44). The first aperture (146) projects into the panel (22) along a first centerline (146) from the panel first surface (48). The first centerline (146) is angularly offset from the panel first surface (48) by a first angle (84). A first tool (150) is arranged with the panel (22). The first tool (150) includes a support structure (152), a locator (156) and a drill guide (154). The locator (156) is mounted to the support structure (152) and projects into the first aperture (146). The drill guide (154) is mounted to the support structure (152) and is arranged adjacent the panel second surface (44). A second aperture (220) is drilled in the panel (22) using the drill guide (154). The second aperture (220) projects into the panel (22) along a second centerline (222) from the panel second surface (44) to the first aperture (146). The second centerline (222) is coaxial with the first centerline (148).
