English:Making and maintaining forging tools and aids — Practical project and reflection

Introduction

Making and maintaining forging tools and aids — Practical project and reflection is the practical-project module of Making and maintaining forging tools and aids. It is designed for vocational learners in Blacksmithing and Artistic metalwork who already have supervised workshop experience in basic hot forging.

Selected jurisdiction: United Kingdom. For legal precision, the workplace-safety duties cited below are the Great Britain framework for England, Scotland and Wales and are checked against the Health and Safety Executive. The occupational-training pathway is labelled England only and is checked against Skills England. Northern Ireland has separate occupational-safety arrangements, and this course does not claim that its law, qualifications or certification are equivalent. No automatic cross-country equivalence is claimed.

Safety boundary: Hot forging, powered grinding, drilling, welding, heat treatment and tool testing are hazardous activities. You must carry out practical work only in an approved workshop, after the required induction, under competent supervision, using the local risk assessment, safe system of work, equipment instructions and task-specific controls. If you have not been authorised for an operation, complete the planning, observation or cold mock-up alternative instead. Official rules, the competent supervisor and workplace instructions always take precedence over this aiMOOC.

This course supports reflective practice; it does not award a qualification, licence, certificate of competence or authorisation to use workshop equipment.

Learning Outcomes

By the end of this module, you should be able to interpret an approved tool brief, plan a safe manufacturing sequence, select known materials, produce and tune a simple forging tool under supervision, inspect tools and aids for serviceability, apply quality criteria, reduce avoidable material and energy waste, record maintenance evidence, and reflect on how you would improve a second iteration.

The project is deliberately evidence-rich. Your final portfolio should connect the drawing, process plan, risk controls, manufacturing evidence, quality checks, maintenance plan and reflection rather than treating them as separate paperwork exercises.

Jurisdiction, Training Context and Authority Check

England Vocational Context

As checked on 1 September 2026, Skills England lists the Blacksmith apprenticeship standard ST0378, version 1.1 as approved for delivery at Level 3, with a typical duration of 48 months. The occupational standard describes a blacksmith as using craft, art or skill to design, shape and join metal components by hot forging and other metalworking processes for small-batch, bespoke or heritage work. It specifically includes the skill of manufacturing and maintaining hand tools such as tongs, punches, chisels, hammers, anvil tools and jigs.

This aiMOOC is educational support for that occupational context. It is not the official apprenticeship standard, end-point assessment, provider curriculum or evidence of successful completion. Employers, training providers and assessors decide how learning evidence is used.

Great Britain Safety Duties Used in This Module

The Health and Safety Executive states that employers must identify hazards, assess risk and eliminate hazards where possible or control the risk under the Management of Health and Safety at Work framework.

For work equipment, PUWER requires suitable equipment, safe use, maintenance, inspection where needed, and adequate information, instruction and training. It also addresses guarding, isolation, hot materials and safe maintenance.

For PPE, HSE guidance requires employers to assess suitability, maintain and store PPE, provide instructions and ensure correct use. PPE is selected after risks have been controlled as far as reasonably practicable; it is not a substitute for eliminating or controlling hazards at source.

Forge work and grinding can be noisy. Under the Control of Noise at Work framework, HSE gives lower and upper daily or weekly exposure action values of 80 dB(A) and 85 dB(A), with an exposure limit value of 87 dB(A) after taking account of hearing protection. A workplace noise assessment determines the required controls.

Dusts, fumes, gases, coatings and other harmful substances may fall under COSHH. HSE requires exposure to materials that can cause ill health to be adequately controlled.

The HSE hearing-protection demonstration above is useful for checking why condition, fit and compatibility matter. Your workplace noise controls and PPE selection still take precedence.

Standards and Conformity Context

The British Standards Institution is the United Kingdom's National Standards Body and maintains the national catalogue of British, European and international standards. UK government guidance explains that designated standards may support a presumption of conformity for relevant regulated products, but they do not replace applicable legal requirements and do not remove the manufacturer's responsibility.

For a workshop-made hand tool or aid, do not attach a conformity claim merely because the tool looks similar to a commercial product. If a drawing, client contract, employer procedure or regulated-product duty cites a standard, verify the current edition and actual scope through BSI and the relevant competent authority. This module does not declare any tool UKCA-marked, CE-marked or automatically compliant with a product standard.

Core Concepts

Toolmaking as a Controlled Process

A good forging tool is not simply a piece of steel that survived the forge. It is a controlled solution to a holding, shaping, cutting, locating, supporting or repeatability problem. In vocational practice you should be able to explain what the tool is for, what load and heat it sees, why the material is suitable, how its geometry controls the work, how it will be inspected, and what evidence shows that it is fit for the intended task.

A practical improvement loop is:

Plan	Make	Check	Reflect	Maintain
Approved drawing, material, sequence and controls	Supervised forging and fitting	Dimensions, alignment, integrity and function	Evidence-based review of choices and errors	Inspection, servicing, records and retirement criteria

This loop applies to Tongs, Punches, Chisels, Hardy tools, Swages, Fullers, Jigs and fixtures, templates, gauges and bending aids.

Forging Tools and Aids: Functions and Practitioner Terms

Type	Typical forge examples	What quality means in practice
Work-holding tool	Tongs with bits or jaws, bosses, rivet or pivot and reins	Secure grip on the intended stock without excessive hand force, twisting or dangerous jaw mismatch
Striking and top tool	Hammer, flatter, set hammer, top fuller	Sound head and eye, appropriate faces and radii, no cracks or dangerous mushrooming, suitable handle and secure fit
Cutting and punching tool	Hot chisel, punch, drift	Correct profile, adequate body section, sound struck end, material-specific heat treatment where required
Anvil tool	Hardy cutter, bottom fuller, swage, bending fork	Correct fit in the hardy hole without dangerous wedging, sufficient support and clearance, sound working surfaces
Aid for repeatability	Jig, former, template, gauge, stop	Locates the work consistently, resists distortion, does not create an unexpected pinch or ejection hazard
Inspection aid	Rule, square, callipers, radius gauge, go or no-go gauge	Gives repeatable checks matched to the approved drawing or workshop tolerance

Anatomy of a Pair of Tongs

The main project uses practitioner terms common in UK forge training. The bits or jaws contact the work. The bosses provide the thicker pivot region. The rivet or pivot joins the two halves. The reins are the long handles. Transitions between these regions should be smooth enough to avoid unnecessary stress concentration.

Workpiece end	Load-transfer zone	Hand-control zone
Bits or jaws grip the specified stock	Bosses and pivot keep the two halves aligned while allowing movement	Reins give reach and leverage while keeping the user's hands away from the heated work

A tong that closes beautifully with no workpiece but rocks or slips on the actual stock is not well fitted. Fit must be checked against the specified section and orientation of the work.

The Anvil as a Tool System

The labelled anvil image identifies the face, horn, step, hardy hole and pritchel hole. In a toolmaking project, the anvil is part of a system: its edges, radii, holes, working height, stand and surrounding clearance influence the result. Never assume that a hardy tool made for one anvil will safely fit another.

Materials, Tools and Workshop Preparation

Material Selection

For this supervised tong project, use only the known material specified by the tutor or drawing. Low-carbon steel is commonly used for many blacksmith's tongs because it forges readily and usually does not require hardening for the gripping function. Higher-carbon or alloy tool steels may be appropriate for punches, chisels or striking tools, but their heat treatment is material-specific and must follow an approved material specification and competent instruction.

Unknown scrap is not an acceptable default for a critical striking, cutting or load-bearing tool. Unknown chemistry, previous damage, hidden cracking, coatings or contamination can make heat treatment and service behaviour unpredictable. Reuse is valuable when the material is traceable and fit for purpose.

Typical Tools and Equipment

Purpose	Typical equipment in a vocational forge	Preparation check
Heating	Approved forge or furnace with the site's ventilation and fuel controls	Instructor authorisation, safe condition, clear hot zone and operating procedure
Forging	Anvil, hand hammer, flatter or set hammer where specified	Faces sound, handles secure, anvil stable, work area clear
Holding	Existing correctly sized tongs, leg vice, approved fixtures	Grip sound, pivot serviceable, jaws fit stock, vice secure
Hole making	Hot punch and drift, or pillar drill where the approved method specifies drilling	Correct tool, guarding and authorisation; no improvised method
Finishing	Files, linisher, bench or pedestal grinder as authorised	Abrasive condition, guards, rests, extraction, eye and face protection, training
Measuring	Steel rule, square, callipers, template or gauge	Clean reference surfaces and agreed dimensions or tolerances
Assembly	Approved rivet, heading or setting tools and support	Correct fit and a controlled method that avoids pinch and ejection hazards

PPE and Clothing Are Task-Specific

Your local risk assessment decides PPE. Typical forge controls may include suitable eye protection, hearing protection where required, protective footwear and close-fitting work clothing appropriate to heat and sparks. Gloves are not a universal answer: they must be selected for the task, heat and snagging risk, and they must not be worn where a rotating-machine procedure prohibits them. Long hair, jewellery, loose sleeves and unsecured clothing can create additional hazards.

PPE compatibility matters. For example, safety spectacles can reduce the seal of some earmuffs; the HSE video above demonstrates why PPE must work as a system rather than as isolated items.

Risk Controls for the Practical Project

Hazard and Control Table

Hazard	Typical source	Control approach before work starts	Stop-work trigger
Burns and radiant heat	Hot stock, forge, hot tools, recently forged material	Defined hot zone, correct work-holding, supervised handling, clear placement rules, suitable clothing and PPE	Lost grip, uncontrolled hot metal, unclear hot or cold status
Flying scale and particles	Hammering, punching, grinding	Sound tools, controlled striking, exclusion distance, guarding and task-specific eye or face protection	Damaged eye protection, cracked tool, unexpected ejection
Hand and pinch injury	Tong pivot, vice, jig, workpiece movement	Correct grip, stable workholding, hands outside pinch zones, deliberate sequencing	Work shifts, fixture loosens, grip becomes unstable
Tool failure	Cracks, mushrooming, thin sections, loose handles, damaged rivets	Pre-use inspection and removal from service when defective	Any crack, loose head or handle, severe deformation, uncertain integrity
Noise	Repeated hammering, power hammer, grinder	Workplace noise assessment, source controls, exposure management and correctly selected hearing protection	Required hearing protection unavailable, damaged or incompatible
Dust, fume and gas	Grinding, welding, coatings, combustion products	Elimination or substitution where possible, suitable LEV or ventilation, COSHH controls and RPE only where specified	Extraction unavailable, visible uncontrolled fume, unknown coating on heated steel
Powered machinery	Grinder, linisher, pillar drill, power hammer or press	PUWER-compliant equipment, guards, isolation, competent authorised user, correct workholding	Missing guard, unusual vibration, jam, damaged abrasive or unauthorised user
Fire	Forge, sparks, hot scale, combustible material	Site fire precautions, housekeeping, separation of combustibles and approved emergency arrangements	Combustible contamination, blocked escape route, uncontrolled flame
Manual handling and fatigue	Long stock, anvils, repeated hammering	Plan movement, use suitable aids, adjust task and pacing, ask for assistance	Loss of control, pain, excessive fatigue or unsafe posture
Quenching or heat treatment	Hot tool, liquid medium, steam or splash	Only under a material-specific approved procedure with supervisor control	Unknown steel, wrong medium, contaminated vessel or no authorised procedure

Stop-work authority applies to every learner. If something changes from the plan, make the situation safe and ask the supervisor before continuing.

Practical Project: Forge and Maintain a Pair of Flat-Bit Tongs

Project Brief

Your supervised project is to produce a pair of flat-bit blacksmith's tongs to grip a stock section specified by your tutor. The tutor provides or approves the drawing, material, blank size, workpiece sample, process route and acceptance criteria.

Your evidence package should contain an annotated drawing, process sequence, risk-control check, photographs where permitted, measurement record, cold fit test, supervised functional test record, maintenance plan, and reflection. If your workshop rules do not permit photography, use sketches and assessor witness notes instead.

The project is chosen because it links Forging allowance, drawing-down, controlled shoulders, boss formation, punching or drilling, riveting, alignment, fit, ergonomics, maintenance and quality inspection in one functional tool.

Step-by-Step Demonstration Under Supervision

The sequence below is a teaching demonstration, not permission to work alone. Dimensions, heats, tooling and machine settings come from your approved workshop documents.

Step	Demonstration action	Quality evidence and supervisor checkpoint
1	Read the drawing and identify the specified stock section, jaw form, boss position, pivot method and rein length.	Explain the function of each feature before any hot work.
2	Confirm known material, blanks, forging allowance, tools, PPE and the local risk controls.	Supervisor signs the start check; unknown or coated material is rejected.
3	Heat only under the approved forge procedure and establish the first bit or jaw and shoulder without thinning the boss region.	Compare the developing profile with the drawing or template.
4	Forge the boss and begin the rein, keeping smooth transitions and sufficient section through the pivot area.	Check for folds, cold shuts, sharp notches, excessive scale loss or distortion.
5	Produce the second half as a deliberate mirror partner rather than relying on correction at the end.	Lay the halves together cold and compare length, offset, boss position and jaw symmetry.
6	Establish the pivot hole by the approved punching-and-drifting or drilling method.	Hole position is checked before assembly; powered equipment is used only by authorised users.
7	Deburr and prepare the mating boss faces using the approved hand or guarded-machine method.	Faces sit together without a burr holding them apart; no critical section is over-ground.
8	Assemble with the specified rivet and set the joint under supervision.	The joint moves smoothly, with controlled side play and no cracked or distorted boss.
9	Tune the bits around the cold reference stock first, checking contact and alignment.	The workpiece is held securely in the intended orientation without excessive squeezing.
10	Carry out the workshop's supervised functional trial, using the tool only for its intended stock and operation.	Stop immediately if the work slips, twists, jaws spring, rivet loosens or alignment changes.
11	Clean only as required, remove dangerous burrs, apply the workshop's approved corrosion-protection practice to cold surfaces, and mark or store the tool as specified.	Tool identity and intended stock size are clear where the workplace requires marking.
12	Complete the quality record, maintenance plan and reflection before the tool enters normal service.	Tutor or competent person accepts, quarantines for correction, or rejects the tool.

Quality Criteria and Functional Inspection

Acceptance Checklist

Criterion	Evidence	Reject or correct before service when
Intended function	Tongs grip the specified test stock in the required orientation	Stock rocks, twists, slips or requires excessive hand force
Jaw fit	Contact is even enough to restrain the stock predictably	One jaw bears on an edge only or jaws force the stock out of line
Alignment	Bits, bosses and reins track as intended	Reins cross unexpectedly, jaws are badly offset or pivot pulls the tool sideways
Pivot	Free controlled movement with acceptable side play	Rivet is loose, cracked, seized or allows unsafe lateral movement
Section integrity	Boss and transitions retain adequate section and smooth load paths	Crack, cold shut, deep lap, sharp notch or critically thin boss is present
Surface condition	Dangerous burrs and sharp accidental edges are removed	Burrs can cut the user or damage the work; grinding has overheated or undercut a critical area
Ergonomics	Rein length, spacing and grip suit the intended operation and user	Pinch point, excessive span or awkward balance prevents controlled use
Traceability	Material and project record are known where required	Critical material identity is unknown or a previous repair cannot be verified
Maintenance readiness	Inspection points and retirement triggers are recorded	No one can state how the tool should be checked or when it must be withdrawn

Quality is not cosmetic perfection. Hammer texture can be acceptable if it does not hide cracks, create sharp stress raisers or compromise fit. Conversely, a polished tool that slips on its workpiece is a poor tool.

Simple Functional Tests

Start with a cold fit test using the approved sample. Check grip, alignment and range of movement. Any hot functional test is carried out only under the supervisor's controlled procedure. A trial should verify the intended function without turning the learner into a test subject for an uncertain tool.

Do not extend a trial beyond the agreed load, stock size or operation. A tong made for flat bar is not automatically suitable for round stock, hammer heads or heavy billets.

Maintenance of Forging Tools and Aids

Inspection Before, During and After Use

PUWER maintenance principles apply broadly to work equipment: equipment must be maintained in a safe condition and maintenance itself must be planned and carried out safely.

Item	Look and feel for	Typical controlled response
Tongs	Loose or seized rivet, jaw wear, bent reins, cracking at boss, poor alignment	Withdraw if integrity is doubtful; adjust or re-rivet only by an approved method, then re-test
Hammer or top tool	Loose handle, cracked eye, chipped face, dangerous mushrooming on struck end	Remove from service; repair, dress or retire under the workshop maintenance procedure
Punch or chisel	Mushroomed head, chipped edge, bending, cracks, lost geometry	Quarantine; recondition only if material and procedure are known, otherwise retire
Hardy tool	Stem deformation, cracking, poor anvil fit, damaged cutting or forming edge	Stop use; correct only by approved repair or replace
Jig or former	Loose stop, distorted locating face, cracked weld or fixing, accumulated scale	Clean, tighten or repair after isolation; verify geometry before return
Measuring aid	Damaged edge, loose slide, contamination, unreadable marks	Clean, check against a reference, recalibrate or replace as the quality system requires

Never grind away visible cracking and return a critical tool to service without competent evaluation. Removing the visible surface does not prove the defect is gone.

A Practical Maintenance Record

Field	Example of useful evidence
Tool identity	Flat-bit tongs, workshop ID and intended stock size
Date and inspector	Date plus learner and supervisor or competent-person initials
Condition found	Pivot free, no crack visible, jaws aligned, minor scale at bit
Action	Cleaned, pivot checked, no repair required
Functional check	Cold sample held without rocking or slip
Status	In service, quarantined, repair required or retired
Next review	According to local inspection frequency and risk

Common Errors and How to Diagnose Them

Error	Likely consequence	Better decision
Boss forged too thin	Weak pivot zone and rapid distortion	Preserve section early; compare with drawing before drawing the rein
Two halves made independently with no comparison	Misaligned jaws and uneven reins	Compare mirror geometry at planned cold checkpoints
Pivot hole misplaced	Jaws cannot meet correctly and movement binds	Establish datum marks and verify hole location before assembly
Rivet set too tight	Tongs seize or require excessive effort	Adjust only by the approved setting method and re-check movement
Rivet left too loose	Side play allows workpiece movement	Correct or replace the pivot and repeat the functional check
Sharp shoulder or deep grinder notch	Local stress concentration	Use controlled radii and avoid aggressive corrective grinding
Unknown scrap used for a critical tool	Uncertain forging and heat-treatment response	Use traceable known material matched to the function
Tool made to a generic shape instead of actual stock	Poor grip even though the tool looks correct	Tune and inspect against the approved sample
Damaged tool remains in circulation	Failure can occur during striking or holding	Quarantine, label and record before repair or retirement
Reflection describes only what happened	Little evidence of vocational judgement	Explain causes, evidence, consequences and the next controlled improvement

Sustainability and Resource Efficiency

Sustainable forge practice starts with design and process control rather than with scrap bins. Calculate sensible forging allowance so you do not start with far more material than needed. Use known-grade offcuts when their identity and condition are suitable for the function. Segregate metal scrap according to the workplace recycling system. Keep forge equipment maintained so fuel or electricity is not wasted through poor condition. Plan the sequence so compatible heats and checks are efficient without rushing. Avoid prolonged overheating, which wastes energy and increases scale loss.

A repair can extend tool life, but sustainability never justifies keeping a cracked or unsafe tool in service. A maintainable design uses replaceable pivots or stops where appropriate, clear tool identification and inspection records. Jigs can often be made modular so a base, stop or former can be reconfigured instead of discarded.

When choosing between a new tool and a repair, weigh material use, energy, repair time, reliability, future inspectability and the consequences of failure. The safest whole-life option may be replacement.

Inclusive Workshop Practice

Competence in blacksmithing is not measured by brute strength. Good work comes from control, planning, appropriate hammer mass, correct work height, efficient sequencing and suitable workholding. Training providers can support access by adjusting bench or anvil arrangements where practicable, using mechanical handling aids, pacing physically demanding work, providing visual and written process plans, and offering non-hazardous mock-ups before live practice.

PPE must fit the individual and work with other PPE. Instructions should be available in accessible formats. Learners should be able to stop work and ask for clarification without pressure. Any adaptation must be checked by the competent tutor so it does not introduce a new hazard.

Reflection

Reflection is part of the technical process, not an afterthought. A useful reflection links evidence to a decision.

Prompt	Strong evidence
What did the drawing predict well?	A measured feature that matched the drawing and why your sequence preserved it
Where did the process diverge?	A specific distortion, heat-loss problem, alignment issue or time delay
What was the root cause?	Tool choice, sequence, workholding, communication, measurement or material movement
What quality check caught it?	Template, callipers, cold fit, visual inspection or supervisor observation
What did you change safely?	A controlled correction approved by the tutor
What would you change next time?	One planned change with a reason and expected benefit
What did you learn about maintenance?	A defect or wear point you can now identify before failure
What did you learn about sustainability?	A concrete change to material use, energy, rework or tool life
What did you learn about your own practice?	A statement about planning, posture, communication, pace or decision-making supported by evidence

A useful final sentence structure is: Because the evidence showed X, I changed or would change Y, which should improve Z, and I would verify that improvement by Q.

Media Observation Tasks

Use the videos and images as evidence sources. Identify which details are universal craft principles and which are specific to one smith, shop, tool pattern or machine. Pay attention to workholding, sequence, inspection and body position. Do not treat a historic photograph or online video as a current safety instruction.

Compare the labelled anvil diagram with the anvil in your own approved training forge. Photograph or sketch differences only if your workplace allows it. Explain why a hardy tool should be fitted and checked for the actual anvil rather than assumed interchangeable.

Expert Review and OER Note

This course is intended for human expert review before high-stakes use. A competent blacksmithing tutor should verify the practical sequence and tool geometry against the workshop's equipment and learner level. The employer or training provider's competent health-and-safety person should verify local risk assessments, extraction, noise controls, fire arrangements, machine authorisations and PPE. A vocational assessor should confirm any claimed mapping to current apprenticeship requirements. A standards specialist should verify any British Standard or designated-standard reference that a real client or product specification requires.
