Assessment Task: Boilermakers G-Clamp and Written Communication Folio.

Weighting: 20%

Teacher: Mr Reilly

Industrial Technology syllabus outcomes to be assessed:

5.1.2 A student applies OHS practices to hand tools, machine tools, equipment and processes.

5.2.2 A student identifies, selects and competently uses a range of hand and machine tools, equipment and processes to produce quality practical projects.

5.4.1 A student selects, applies and interprets a range of suitable communication techniques in the development, planning, production and presentation of ideas and projects.

Part A – Practical Project (70%)

Task Description:

You will be supplied with 25mm x 5 mm flat bar pre-cut to the dimensions of your G Clamp drawing. You are required to accurately clean up by filing, mark out, Mig weld and use the lathe to fabricate an adjustable G Clamp that is capable of holding an assortment of materials together.

This task will introduce you to:

·  Sketching

·  Industrial marking out techniques

·  Mig welding techniques

·  Lathe techniques

·  Threading techniques

·  Oxyacetylene start up, use of and shut down procedures

Part B – Written Communication (30%)

You MUST submit a Written Communication folio that documents the process followed to make your project. Your written communication folio must include:

·  The folio submitted in an A4 display folder

·  A title page with a suitably chosen title, your name, class and a picture of a G Clamp

·  A contents page listing the following sections that you are to include in your design and management folio.

The Design Brief: (5 marks)

·  The design brief is to be written so that it clearly states what the proposed project is to look like when completed

·  Establish and list some criteria you see as essential for the successful completion of the project.

·  This section should fill at least one page

Research and Information Collection: (5 marks)

·  This section documents the collection of a wide range of information related to the project. You should aim to investigate alternative materials, processes and equipment that could have been used to produce your G Clamp

·  This section should fill at least one page.

Development of design Ideas: (10 marks)

·  This section should document any ideas you had in relation to the design of the G Clamp

·  Use drawings, sketches and notes explaining the possible design and alternatives you considered

·  This section should fill at least one page

Selection and Justification of Resources: (10 marks)

·  Explain why you have selected your final design and list the reasons why you rejected the other options

·  Include a full scale drawing of your chosen design

·  An orthographic drawing of your project, making sure you add dimensions and appropriate labelling

·  This section should fill at least one page

Construction Steps, Techniques and Processes: (20 marks)

·  Include a table that summarises the timber components used to construct you project

·  List the sizes of each component ( cutting list )

·  Write out specific steps used to construct your G Clamp

·  A list of hand tool and machine tools used during the production process

·  This section should fill at least three page

Evaluation: (10marks)

·  Write an appropriate final evaluation that addresses any problems you may have experienced or any mistakes you made

·  Then outline how you solved or fixed these problems

·  Also discuss any possible design changes you could have made.

·  Then make comment on your personal work habits e.g. good or poor use of allocated time

·  This section should fill at least one page.

Marking Criteria: Students will be assessed on their ability to

·  Design a functional storage component

·  Follow marking out, cutting and folding procedures

·  Produce a quality project that is finished to a high metal working standard

·  Present a quality folio that adheres to the marking criteria.
