Produce standard templets and moulds
This subtopic covers the essential skills required to produce accurate standard templets and moulds for stonemasonry. Learners must interpret technical drawings and specifications, set out full-size templates using drawing conventions, select appropriate materials and tools, and construct templates that will guide the cutting and dressing of stone. Mastery of these processes ensures precision in stonework, reduces material waste, and upholds the quality standards expected in heritage and contemporary masonry projects.
Assessment criteria
Topic Overview
The NOCN Level 2 Diploma in Stonemasonry – Banker (Construction) focuses on the craft of shaping and finishing stone using hand tools and machinery. This qualification is designed for those working in a banker mason workshop, where you will learn to produce architectural stonework such as quoins, voussoirs, columns, and decorative features. It covers essential skills like reading technical drawings, setting out, template making, and using pneumatic tools, all while adhering to health and safety regulations. Mastery of banker masonry is vital for preserving historic buildings and creating new stone structures, making it a cornerstone of the construction industry.
The diploma is part of the wider construction and built environment sector, linking directly to careers in heritage conservation, restoration, and new-build projects. You will develop practical competence in cutting, carving, and finishing stone to precise specifications, as well as understanding the properties of different stone types. This qualification also emphasizes quality control and teamwork, preparing you for supervisory roles or further study in stonemasonry. By the end, you will be able to produce complex stone components independently, contributing to the longevity and aesthetic of architectural heritage.
Key Concepts
Core ideas you must understand for this topic
- →Stone types and properties: Understand the characteristics of limestone, sandstone, granite, and marble, including their workability, durability, and reaction to weathering.
- →Setting out and template making: Accurately transfer dimensions from technical drawings to stone using squares, bevels, and templates to ensure precise cuts.
- →Tool usage and maintenance: Master the use of banker masons' tools such as chisels, mallets, pitching tools, and pneumatic hammers, including sharpening and dressing techniques.
- →Jointing and fixing methods: Learn to create various joints (e.g., dowel, cramp, and mortar joints) and fixings for stone assemblies, ensuring structural integrity.
- →Health and safety: Apply COSHH regulations, manual handling techniques, and safe use of abrasive wheels and dust extraction systems to minimize risks.

Assessment Criteria
Key criteria assessors look for in your portfolio
- Award credit for demonstrating the ability to extract critical dimensions and profiles from architectural drawings and produce a clear, annotated working sketch.
- Look for accurate full-size setting out using appropriate drawing instruments and adherence to standard conventions such as clear line work, dimensioning, and labelling of faces.
- Assess the selection of template materials (e.g., plywood, zinc, or hardboard) justified by the intended use, durability, and workability, with consideration of cost and sustainability.
- Evaluate the finished templet or mould for dimensional accuracy (within ±1 mm tolerance), surface finish, and robust construction suitable for repeated use on the banker.
- Credit should be given for effective use of tools such as scribers, bevels, straight edges, and templates cutters, with all work carried out safely and with correct PPE.
Assessment Guidance
Guidance for achieving higher grades
- 💡Always begin by thoroughly checking the provided drawings for notes, revisions, and key dimensions; cross-reference with any schedules to confirm the correct template version.
- 💡During practical assessment, verbalise your decision-making as you select materials and tools—this demonstrates underpinning knowledge and can salvage marks if the final product has minor flaws.
- 💡When setting out, mark all critical points and joints clearly, and use a consistent orientation (e.g., face marks) to avoid confusion during stone preparation.
- 💡Test your template against a straight edge and check all angles with a bevel before submission; take time to label it with relevant information (job reference, date, orientation) to show professional working practice.
- 💡Always check your setting out against the drawing twice before cutting. Marks are often lost due to measurement errors that could have been caught with a simple re-check.
- 💡Demonstrate safe working practices consistently throughout your practical assessment, including correct PPE use and dust control. Examiners look for a safety-first mindset as much as technical skill.
- 💡When finishing a surface, use the correct grade of abrasive and work in stages. Rushing to a fine finish can leave scratches or uneven areas; show you understand the progression from coarse to fine.
Common Mistakes
Common errors to avoid in your coursework
- Misinterpreting scale on drawings and failing to apply appropriate scale factors when enlarging to full size, leading to dimensionally incorrect templates.
- Neglecting to account for the thickness of the template material when transferring profiles, which results in undersized or oversized moulds.
- Using insufficient reference points or failing to establish a datum line, causing cumulative errors across the set-out.
- Selecting unsuitable sheet material (e.g., warped plywood or flimsy card) that distorts during use and compromises the accuracy of subsequent stone cutting.
- Rushing the finishing process—leaving rough edges or ignoring subtle curvatures—so the mould does not faithfully represent the intended stone profile.
- Misconception: All stone is the same to work with. Correction: Different stones have varying hardness, grain, and porosity, requiring specific tools and techniques. For example, sandstone is easier to carve than granite, which demands diamond-tipped tools.
- Misconception: Templates are optional for simple shapes. Correction: Even basic stone components require accurate templates to ensure consistency and fit, especially when replicating historical features or matching existing masonry.
- Misconception: Power tools replace hand skills entirely. Correction: While pneumatic hammers speed up roughing out, hand tools are essential for fine detailing, finishing, and achieving the required surface texture (e.g., tooled, rubbed, or polished).
