The document provides instructions for marking out a hexagon shape on a piece of metal using common metalworking tools. It describes 5 essential tools - steel rule, dividers, scribe, centre punch, and engineer's square. It then gives a step-by-step process for using these tools to precisely mark out the points and lines of a hexagon, including applying engineer's blue, drawing center and edge lines, punching indentations at points, and using a divider to scribe arcs between points, resulting in a completely marked out hexagonal shape.
