2. Organizational Preparations

To ensure a trouble-free course of instructions, exercises and vocational practice, it is necessary to prepare the training well, with the following measures to be taken:

2.1. Planning the Training in Straightening Techniques

Starting from the total hour volume, the hours spent on the individual training sections of this vocational unit should be planned in a differentiated manner. For the following training sections it is recommendable to prepare a schedule:

- for the introduction to the techniques in the form of an instruction,
- for required demonstration,
- for the task-related instruction in preparation of the exercises,
- for the implementation of the exercises,
- for recapitulation and controls.

In planning the time, the following additional factors are to be taken into consideration:

- the level of education of the trainees,
- the training conditions,
- the future field of working of the trainees,
- the degree of difficulty of the training sections.

The acquisition of skills and abilities is the focal point of each training section; therefore, the exercises must be given the major portion of time.

2.2. Preparing the Instructions on Labour Safety

Before beginning with the exercises, a brief instruction has to be given on the appropriate use of tools and equipment and on accident-free working. In general, the same regulations are valid as for hammering and bending.

The following points must be especially emphasized:

- Use only clean and intact tools and equipment.

- When using hammers, make sure that the head of the hammer is firmly connected with the shaft by the cotter punch.

- Choose the appropriate support - it must have an inflexible surface.

- The workpieces must be firmly clamped so that they are not torn away by the hammer blows.

- When working at presses make sure that your hands and head are protected.

- The use of welding torches is only allowed after previous instructions given by the instructor.

- Pay attention to fire protection: place water ready for fire fighting; do not work near inflammable materials.

Knowledge of these instructions has to be confirmed by the trainees by signature in the control book.

2.3. Providing the Teaching Aids

- The "Trainees' Handbook of Lessons - Straightening" is to be distributed among the trainees according to their number.

- Especially indicative illustrations from the "Trainees' Handbook of Lessons" should be arranged for as blackboard drawings.

- Workpieces which have been deformed by transport or machining may be used as visual aids.

- Special tools not yet know to the trainees, e.g. moving irons, may be used as visual aids, too.

- If in the field of straightening transparencies for overhead projection are available, they should be included in the lessons.

2.4. Providing the Working Means

- As a theoretical basis of the exercises to be carried out the "Instruction Examples for Practical Vocational Training - Straightening" should be distributed among the trainees.

- The basic material required for the exercises should be prepared and provided in sufficient quantity according to the details given in the "Instruction Examples...".

- The workshop has to be checked as to its complete equipment with tools, devices, measuring and testing instruments as well as auxiliary means according to the exercises planned.

- Recommended basic equipment

· Locksmith's hammers, straightening hammers, light metal hammers, mallets, rubber hammers

· Moving irons and tap wrenches

· Tongs and damps

· Welding torches with accessories

· Hand screw presses

· Vice, straightening plate

- Straightening machines that shall be used for mechanical straightening must be checked as to their serviceability with regard to safety before starting the exercises.
