Produce complex templets and moulds
This subtopic focuses on interpreting architectural drawings and specifications to produce accurate full-size templets and moulds for complex stone profiles, ensuring precision in dimensions and angles to guide the cutting and dressing of stone. It encompasses applying standard stonemasonry conventions and troubleshooting common fabrication issues, essential for achieving high-quality finished work in banker masonry.
Assessment criteria
Topic Overview
The NOCN Level 3 Diploma in Stonemasonry – Banker (Construction) is an advanced vocational qualification designed for stonemasons who have already mastered basic skills and wish to specialise in banker work. Banker masons work at a bench (the banker) to shape and carve stone using hand tools and power tools, producing complex architectural elements such as mouldings, tracery, capitals, and decorative features. This diploma covers advanced techniques in setting out, template making, and precision carving, ensuring you can produce high-quality stonework that meets both aesthetic and structural requirements.
This qualification is essential for progressing to supervisory roles or running your own stonemasonry business. It sits within the wider construction and built heritage sector, where traditional craftsmanship is highly valued for restoration and conservation projects. By mastering banker masonry, you become capable of creating bespoke stone components that are critical to the integrity and beauty of historic and contemporary buildings. The diploma also emphasises health and safety, material knowledge, and the use of modern tools alongside traditional methods, preparing you for real-world construction environments.
Key Concepts
Core ideas you must understand for this topic
- →Setting out and template making: Creating accurate full-size drawings and templates from architectural details to guide the carving process.
- →Moulding profiles: Understanding and reproducing classical and contemporary mouldings (e.g., ovolo, cavetto, cyma recta) using gauges and templates.
- →Stone carving techniques: Using chisels, mallets, and power tools (e.g., angle grinders, pneumatic hammers) to shape stone to precise dimensions and finishes.
- →Jointing and fixing: Preparing stones for assembly with mortar, cramps, dowels, or other fixings, ensuring structural stability and weathertightness.
- →Material selection: Identifying different types of stone (limestone, sandstone, granite, marble) and their properties, including durability, workability, and weathering characteristics.
Learning Objectives
What you need to know and understand
- Know how to interpret information for complex templets and moulds., Be able to interpret information to produce complex templets and moulds., Know how to produce complex templets and moulds and apply standard information., Be able to produce complex templets and moulds and apply standard information.
Assessment Criteria
Key criteria assessors look for in your portfolio
- Award credit for demonstrating correct interpretation of scale, projection, and dimensioning from working drawings when transferring information to templet material.
- Look for evidence of using appropriate marking-out tools and techniques to achieve required tolerances, typically ±0.5mm for fine work.
- Ensure candidate checks the templet against the original information and amends any discrepancies, demonstrating iterative quality control.
Assessment Guidance
Guidance for achieving higher grades
- 💡Always cross-reference both plan and elevation views to ensure the templet accurately represents the 3D form of the stone.
- 💡For complex curves, create a series of reference points rather than relying on a single template, and check frequently against the stone during dressing.
- 💡Always show your setting out and template work in detail – examiners look for accuracy in measurements and the ability to transfer a 2D drawing to a 3D stone surface.
- 💡Demonstrate safe working practices consistently, especially when using power tools. Mention specific PPE (e.g., dust masks, ear defenders) and dust control methods.
- 💡Explain your choice of tools and techniques for each stage – this shows understanding of why certain methods are used, not just how.
Common Mistakes
Common errors to avoid in your coursework
- Misreading orthographic projections, leading to incorrect proportions on the templet.
- Neglecting to account for material thickness or joint allowances when creating the mould.
- Using damaged or inaccurate marking tools, resulting in cumulative errors in the final profile.
- Misconception: Banker masonry is just about carving decorative shapes. Correction: It also involves precise setting out, structural understanding, and ensuring the stonework integrates correctly with the building's overall design.
- Misconception: Power tools are not used in traditional stonemasonry. Correction: Modern banker masons use a combination of hand tools and power tools (e.g., angle grinders with diamond blades, pneumatic hammers) to increase efficiency while maintaining quality.
- Misconception: Any stone can be used for any project. Correction: Different stones have different strengths, porosities, and weathering behaviours; selecting the wrong stone can lead to structural failure or rapid decay.
