Year 10 Resistant Materials - The Screwdriver Project

The Task

To design and make a screwdriver for small jobs, (non-electrical) around the home.


1. The screwdriver will be safe to use.
2. You will produce a high quality product.
3. The blade may be permanently secured or it will be able to be removed.
4. You will produce a cutting list of materials and sizes.
5. You will produce an orthographic drawing showing, a front view and side view with sizes shown.
6. You will keep a diary of practical processes that will include names of tools, machinery, materials and safety considerations.

You will learn the following skills;

· How to use the forge to shape the blade of the screwdriver.
· How to use the lathe to taper turn, face off, parallel turn and to bore the internal hole in the handle for the blade.
· How to use taps and dies to make internal and external threads.
· How to use the brazing hearth to permanently metals together.
· How to case harden a piece of metal.
· You will learn how to use a lathe and understand lathe speeds and lathe tools.
· How to dip coat metals in order to plastic coat them.
· To use machinery safely.
· Surface treatment and finishes.

Programmes Of Study References

1. Pupils should be given the opportunity to develop their design and technology capability through:
a Assignments in which they design and make products. Taken together these assignments should require activity related to industrial practices and the application of systems and control;

b Focused practical tasks in which they develop and practise particular skills and knowledge;
2. Pupils should be given opportunities to:

2a Apply skills, knowledge and understanding from the programmes of study of other subjects, where appropriate, including art, mathematics and science.

2a To develop and use design briefs and detailed specifications;
2b To anticipate and design for product maintenance, where appropriate;
2c To design for manufacturing in quantity;
2f To determine the degree of accuracy required for the product to function as planned, taking account of critical dimensions and tolerances in determining methods of manufacture;
2j To be flexible in their working practices, in order to respond to changing circumstances and new opportunities;
2k To apply and apply test procedures to check the quality of their work at critical points during development, and to indicate ways of improving it;
3. Making

3a To match materials and components with tools, equipment and processes;
3b To use tools and equipment accurately and efficiently to achieve an appropriate fit and finish and reliable functioning in products that match the specification;
3c A range of industrial applications for a variety of familiar materials and processes;
3k 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;
3l To ensure through testing, modification and evaluation, that the quality of their products is suitable for intended users.

4.Knowledge and understanding
4d About a variety of self-finishing and applied finishing processes, and to appreciate their importance
For aesthetics and functional reasons;

Year 10 - Construction Screwdriver

The Task

To design and make a screwdriver for small jobs, (non-electrical) around the home. The screwdriver may include interchangeable bits e.g. scraper.
Setting The Task
British wealth was based historically on engineering. To create an awareness of how to manufacture a quality product in steel and to use machines safely they will make a set traditional piece.

Main Aims

1. To be able to manufacture a quality product in steel.
2. To use machines accurately and safely.
3. To know and apply relevant heat treatment.
4. To be able to join metals.
5. To be able to plan and organise their own time.

· The need for quality.
· The need for accuracy.

Health and Safety
· To be able to work in a manner that is safe for themselves and others.


The Nature Of The Product
Each pupil will produce a small dip coated screwdriver.
