Individual manual marking and drilling of holes Errors are probable within each hole group and between groups. Satisfactory for small isolated hole groups only. Match marking Achieved by pre-drilling approximately half the holes in the components, then assem-bling the components in their calculated relative geometry and marking the holes through. The components are then disman-tled and drilled
