Measuring and Marking Out
Whilst you are in the workshop, you are required to select suitable measuring and marking out methods and
equipment for three different applications. You will be making a Drill Drift, a Bevel Gauge and a Tool Makers Clamp.
This means that you are expected to use your knowledge and understanding of the methods and equipment for
measuring and marking out discussed in Task 1a.
During your sessions in the workshop, you will be observed working in this way.
YOU MUST MAKE SURE YOU GET YOUR OBSERVATION SHEET SIGNED TO ACHIEVE THIS
GRADE CRITERIA.

Provides a datum flat surface on which to place the work piece. A
scribing block or height gauge can then be used from the datum.
Sometimes an angle plate is placed onto the plate.
Irregular shapes without flat surfaces can be clamped to the angle
plate and marked out using a scribing block – Is also used to
keep thin material vertical when marking out
When placed onto the surface plate, adjust the height and scribe
along the work piece. Adjust to the datum and transfer height to
another part of the work piece.
Used for measuring on work piece or setting other tools such as
height gauge

Defective Measuring and Marking Out Equipment
Reporting defective and/or unsafe equipment
During your work, marking out each of your three components, you may
come across ‘defective’ equipment. What should you do with it?
•it may be defective in that it is totally un-usable
•it may be useable but inaccurate
•It may be un-safe to the user
Using a ‘Defective Equipment Report sheet’, you will produce a report for
three pieces of faulty equipment stating:
•
the correct name of the piece of faulty equipment
•
the defect/fault (what is the problem)
•
the implications of the fault if it was continued to be used
•
the appropriate remedial/corrective action to make the equipment
non-defective/safe

For this task, you will be observed carrying out the task of marking out the three components to your work plan.
Ensure that you have the correct tools and equipment available.
You will be observed throughout the process and will be assessed on the following:
Processes: Correct processes used
Tools & Equipment: Correct tools and equipment used and used correctly
Health & Safety: Suitable H&S measures used throughout
Quality Check: That you are constantly checking you work throughout.
Time Check: You are aware of the time constraints and work within them

Key Skills:
For this task, you will be observed carrying out the task of marking out the three components to your work plan.
To gain a ‘Merit’ grade for this task, you will need to carry out appropriate checks to ensure that your marking out of the
components are to the requirements of the drawings provided and that the appropriate machining and material removal
techniques are considered. Again, you will be observed for this – you should ask questions about the drawings if you feel that
not enough information is provided.

Key Skills:
For each of the three work pieces covered in the previous tasks, you must ‘JUSTIFY’ your CHOICE of measuring and marking out
equipment.
Justify WHY you decided to mark out your first ’DATUMN LINE’, the EQUIPMENT chosen (its use) and the TECHNIQUES used.
CRITICALLY EVALUATE your decisions giving good reasons and SUBSTANTIATE these (why you chose them), say WHAT you
did, and HOW you did it.
