What tool is used to align the hole marking with the center of the larger hole in the drilling template?

The bushing is a critical tool used in aerospace assembly when it comes to aligning hole markings with the center of larger holes in a drilling template. It serves as a precise guide that fits into the pre-drilled hole, allowing the operator to accurately position the drilling equipment. This precision is essential for maintaining structural integrity and ensuring that components fit together as designed.

Using a bushing minimizes the potential for misalignment during the drilling process, which can lead to costly rework and potential safety issues. It acts as a reference point, providing a physical location for the drill bit to start, ensuring that the drilling is performed exactly where it is required. This level of accuracy is crucial in aerospace applications, where even small deviations can have significant implications for the performance and safety of the aircraft.

In contrast, while a bracket might assist in providing support or stability, it doesn't inherently offer the alignment capability that a bushing does. A tape measure can be useful for general measurements but does not provide the same precise alignment for drilling. A marker can indicate where holes should be, but it lacks the mechanical precision required for accurate drilling. Therefore, the bushing stands out as the correct tool for achieving alignment in this context.
