What Engineering Model Makers do:

• Study blueprints, drawings, and sketches to determine material dimensions, required equipment, and operations sequences.
• Set up and operate machines such as lathes, drill presses, punch presses, or bandsaws to fabricate prototypes or models.
• Lay out and mark reference points and dimensions on materials, using measuring instruments and drawing or scribing tools.
• Rework or alter component model or parts as required to ensure that products meet standards.
• Devise and construct tools, dies, molds, jigs, and fixtures, or modify existing tools and equipment.
Grind, file, and sand parts to finished dimensions.
Cut, shape, and form metal parts, using lathes, power saws, snips, power brakes and shears, files, and mallets.
Inspect and test products to verify conformance to specifications, using precision measuring instruments or circuit testers.
Drill, countersink, and ream holes in parts and assemblies for bolts, screws, and other fasteners, using power tools.
Consult and confer with engineering personnel to discuss developmental problems and to recommend product modifications.
Assemble mechanical, electrical, and electronic components into models or prototypes, using hand tools, power tools, and fabricating machines.
Align, fit, and join parts, using bolts and screws or by welding or gluing.
Record specifications, production operations, and final dimensions of models for use in establishing operating standards and procedures.
Wire and solder electrical and electronic connections and components.
