Encyclopedia > Marking out

Marking out or layout is the process of transferring a design or pattern to a workpiece, as the first step in the manufacturing process. It is performed in many industries or hobbies although in the repetition industries the machine's initial setup is designed to remove the need to mark out every individual piece. All Saints Chapel in the Cathedral Basilica of St. ... For other uses, see Pattern (disambiguation). ...


The actual method is unique for each field of expertise, some common areas and their needs are listed below as examples of the variation in an otherwise simple process.

Engineering/Machining

In the metal trades area, marking out consists of transferring the dimensions from the plan to the workpiece in preparation for the next step, machining or manufacture. Technical drawing, also known as drafting, is the practice of creating accurate representations of objects for technical, architectural and engineering needs. ...


Tools that are peculiar to the engineering/machining area are typically

  • Surface plate or marking out table — provides a true surface from which to work
  • Angle plates — assist in holding the workpiece perpendicular to the table
  • Scriber — is the equivalent of a pen or pencil. It literally scratches the metal surface leaving behind a fine, bright line.
  • Vernier height gauge or scribing block — allows lines to be scribed at a preset distance, from the tables surface.
  • Surface gage — an ungraduated comparison measuring tool that performs much the same function as the vernier height gage. It is often used in conjunction with a dial indicator and a precision height gage.
  • Marking blue — to provide a usable writing surface by covering any existing scratches and providing a contrasting background.
  • Protractor — to assist in the transfer of angular measurements
  • Combination square — an alternative tool for transferring angular measurements
  • Square — to transfer 90 ° angles to the workpiece
  • Punches — either prick or center punch to create permanent marks or dimples for drill bits to start in.
  • Ball peen hammer — used in conjunction with the punches to provide the striking blow needed.
  • Dividers or measuring compass — for creating circles or arcs.
  • Automatic center punch — a spring loaded punch that creates prick punch marks with out the need for a ball peen hammer

The "chalk" is actually a small pre-cut block of talc (soapstone). These talc blocks can be sharpened to a stronger point than the softer blackboard chalk. The color of the chalk provides good contrast against the dark color of the hot rolled steel that is generally used. Talc (derived from the Persian via Arabic talq) is a mineral composed of hydrated magnesium silicate with the chemical formula H2Mg3(SiO3)4 or Mg3Si4O10(OH)2. ... The lid of a pyrophyllite box. ... A blackboard, with multiple colors of chalk A blackboard or chalkboard is a reusable writing surface on which text or drawings are made with chalk or other erasable markers. ...
