Year 10 Industrial Products - The Candle-Stick Holder Project

The Task

You have been asked to create candlestick holders for a local craft fair. Every item sold in the fair will exhibit traditional craft skills.

Requirements

1. You will need to research various sizes/diameters of candles.
2. To create a set of initial ideas showing a variety of different candle- stick holders.
3. To make a working drawing of the chosen holder showing dimensions.
4. A cutting list showing parts and sizes.
5. You will make a finished mild steel/copper, candlestick-holder using forging techniques and beaten metalwork techniques. The centre- lathe may be used if necessary.

You will learn the following skills;

Forging techniques
· How to form a twist in hot metal.
· How to draw down hot metal to a point.
· How to bend hot metal to produce a right angle.
· How to scroll hot metal to create decorative shapes.
· Annealing (in order to soften metal so as to make it easier to shape).

Beaten metalwork techniques
· Hollowing (making a bowl shape in sheet metal).
· Planishing (creating a decorative pattern on the surface of sheet metal).

Brazing
· Permanently joining metal pieces together.

Theory
· Industrial forging techniques as opposed to traditional blacksmiths forging.
· Mass production in contrast to the production of
one off individual items.

Programmes Of Study References

3i To produce and use detailed working schedules that will achieve the desired objectives and provide alternatives to possible problems;
3h How graphic techniques, I.T equipment and software can be used in a variety of ways to model aspects of design proposals and assist in making decisions;
3l To ensure that the quality of their products is suitable for intended users.

4 Making Skills
4a To match materials and components with tools, equipment and processes;
4b To use tools and equipment accurately and efficiently to achieve an appropriate fit and finish and reliable functioning in products that match the specification;
4e How products are manufactured in quantity, including the application of quality control and assurance techniques;
4h To produce and use detailed working schedules that will achieve the desired objectives, setting realistic deadlines for the various stages of manufacture, identifying critical points in the making process and providing alternatives to possible problems;
4I To be adaptable in their working practises, in order to respond to changing circumstances and new opportunities;
4k To apply and devise test procedures to check the quality of their work at critical points during development, and to indicate ways of improving it;

5d About a variety of self-finishing and applied finishing processes, and to appreciate their importance
For aesthetics and functional reasons;
5e That to achieve the optimum use of materials and components, account needs to be taken of the complex interrelations between material, form and intended manufacturing processes;
7 Products and applications

Pupils should be taught to relate workings and functions of a wide range of products and applications to:
7a The intended purpose of the product;
7b The components available for use in the product;
7c The choice of materials and components and the way in which they have been used;
7d The process used to produce them;
7e The application of scientific principles;
7f The market for which the product is intended;
7g The range of alternative products and solutions.
9a Taking responsibility for recognising hazards in the products, activities, including the unfamiliar;

Technical Knowledge and Understanding

· Heat forming of metals - Forging (bending, twisting, drawing down, scrolling.)
· Beaten metal work techniques (hollowing and planishing)
· Application of a variety of metal finishes (lacquer and hammerite paint)
· The need for jigs and formers (twisting wrench)
· Mass production as opposed to individual products.
Tools and Equipment Needed
· Chip forge Flux
· Anvil Goggles
· Tongs Gloves
· Twisting wrench Brazing hearth
· Ball- Pein hammers
· Sandbags
· Bossing mallets
· Square section mild steel bar
· Copper and mild steel sheet
· Brazing rod/smelter

Using Mathematics

· Measuring and accurate marking out. Geometry

Using I.T
· C.A.D packages to draw the holders.

Using Science
· Heat treatment

Using Other Subjects

Using Economic And Industrial Understanding

· Mass production as opposed to single one off items.

Year 10 - Engineering Candlestick holder

The Task
To research various sizes/diameters of candles. Using forging techniques and metal beating techniques, produce an attractive candlestick holder from mild steel, square section bar and thin sheet copper or sheet mild steel.

Setting The Task
You have been asked to create candlestick holders for a craft fair. Every item sold in the fair will exhibit traditional craft skills.

Main Aims
1. To be able to work heated metal to create attractive shapes.
2. To be familiar with forging techniques.
3. To be familiar with beaten metalwork techniques.
4. To understand that different metals require different finishes to protect them.
5. To join metal permanently and temporarily.
6. To be aware of the current costs of materials and the current price of craft products.

Values
Technical
· Forging processes Beaten metalwork Brazing
· Forming a twist Hollowing Application of finishes
· Drawing down Planishing Metal theory
· Bending
· Scrolling
· Annealing

The Nature Of The Product
· Each pupil will create a set of initial ideas showing a variety of different candlestick holders.
· Each pupil will produce a working drawing of the chosen holder showing dimensions.
· Each pupil will produce a cutting list showing parts and sizes.
· Each pupil will create a finished holder using forging techniques, beaten metal work techniques
And the use of the centre lathe if required.
· Each pupil will study industrial forging techniques as opposed to traditional blacksmiths forging.
· Each pupil will learn of mass production in contrast to production of one off individual pieces.
