Topic Synopsis
This subtopic focuses on the practical skills and underpinning knowledge required to safely and effectively use hand tools to produce formed jewellery or silverware components. Learners will develop proficiency in techniques such as raising, planishing, doming, and bending, while understanding tools like hammers, stakes, and swage blocks. Mastery ensures the production of accurate, well-finished components that meet design specifications and industry standards.
Key Concepts & Core Principles
- Design development: From initial sketches and mood boards to technical drawings and CAD models, understanding how to refine ideas into manufacturable designs.
- Metalworking techniques: Including sawing, filing, soldering, annealing, and forming for precious metals like gold, silver, and platinum.
- Stone setting: Methods such as claw, bezel, pave, and channel setting, requiring precision to secure gemstones without damage.
- Finishing and polishing: Achieving high-quality surface finishes through processes like sanding, buffing, and electroplating.
- Health and safety: Compliance with COSHH regulations, safe use of tools and chemicals, and proper workshop practices.
Exam Tips & Revision Strategies
- In your portfolio, include annotated photographs showing each stage of the forming process, highlighting tool selection, setup, and safety checks.
- Prepare evidence of quality control by presenting one component that meets specification alongside one with a deliberate fault, with a written explanation of the cause and correction.
- During practical assessment, verbally justify your choice of hammer and stake combination for the given metal and form, demonstrating underpinning knowledge.
- Always refer to the provided job specification or drawing before starting—measure and mark out your metal carefully to avoid waste.
- Practice forming techniques on scrap metal first to familiarise yourself with how the material reacts under different tools.
- Photograph or video your process as evidence of correct tool usage and safety compliance, especially for portfolio-based assessments.
- Plan your annealing stages in advance; for complex forms, several annealing cycles may be needed to prevent work hardening.
Common Misconceptions & Mistakes to Avoid
- Failing to anneal metal sufficiently between stages, leading to work hardening and cracking during forming.
- Using a hammer face that is too large or incorrect for the task, resulting in uneven texture and poor shape definition.
- Neglecting to secure stakes or formers properly, causing instability and imprecise forming, which compromises component quality.
- Using excessive force with a metal hammer on thin gauge sheet, causing dents or distortion that cannot be easily corrected.
- Failing to anneal work-hardened metal before continued forming, leading to cracking or splitting.
- Neglecting to secure workpieces firmly in a vice or on a stake, resulting in inaccurate shapes or personal injury.
Examiner Marking Points
- Award credit for demonstrating consistent and correct use of personal protective equipment (PPE) including goggles, ear defenders, and appropriate clothing during all forming activities.
- Award credit for selecting and using the correct forming tools (e.g., raising hammer, planishing hammer, doming punch) in alignment with the required metal shape and thickness.
- Award credit for producing formed components that meet the specified dimensional tolerances and exhibit smooth, uniform contours free from tool marks and distortions.
- Award credit for demonstrating correct selection of forming tools (e.g., doming punch, rawhide mallet) appropriate to the metal and desired shape.
- Evidence of consistent, safe working practices must be shown, including the use of personal protective equipment (PPE) such as safety glasses and appropriate workshop attire.
- Assessors should look for accurate interpretation of technical drawings or specifications to produce components within stated tolerances.
- Credit is awarded for evidence of annealing metal correctly to prevent cracking during forming.
- Candidates must demonstrate proper tool maintenance and storage before and after use.
