Metalworking

Cut, shape and finish metal with care

Metal is unforgiving. A wrong blade, too much heat or a loose workpiece can ruin a part, and drilling, cutting and grinding all throw sharp chips and sparks. Different metals such as steel, aluminum and brass behave differently, so one method does not fit every job.

The guides here show how to measure and mark metal, cut it with saws and grinders, drill and tap holes, bend and file it, and finish edges and surfaces. You learn how to hold work safely in a vise, pick cutting speeds and lubricants, and keep tools sharp. Eye protection, gloves where suitable and tied-back hair matter every time. For parts that bear heavy loads or affect safety, consult a machinist or an engineer. Each guide lists the tools, steps and checks involved, so you can plan the work before you make the first cut and avoid costly mistakes.
