Learn about Machines - how they work, how to maintain them and more.

  • Learn to understand different machinery.
  • Learn how to service them.
  • Learn how to extend their life by repairing them.

Mechanics is the study of machines, and this course is relevant to both the simple such as household appliances, to the complex, such as automobiles.

Machines have become so much a part of modern life that we can easily take them for granted. Most people don’t even give a second thought to how the machines they use are functioning; that is until they stop functioning.

Learning more about mechanics can enable you to do so much more with machines though, from using them more appropriately and safely to maintaining and repairing them when required. 

Some machinery is relatively simple and easier to learn about, but other machines can be much more complex and will require far more learning and experience to properly understand.

This course lays a foundation for understanding and working with all machines, each lesson building upon what you learnt in the previous ones, gradually expanding your awareness and understanding of how and where engines can be used to power machines, and how different types of machines function.

Machines and Tools
Buying or making a machine, maintaining and repairing machinery requires a well organised and equipped workshop. 

This course helps you to not only understand machines, but also the tools used to work with machines, and what tool is appropriate for what job.

Every job you undertake may be achievable with a variety of different tools, but to do the job properly and achieve the best result with the least effort, you should use the best tool for the job and not just an “acceptable compromise”.  

To choose the best tool for any job you need to understand all of your equipment options, the techniques for using that equipment, and what is needed to keep that equipment in good condition.

Consider the following:
  • Strong tools will take greater physical stress and handle heavier jobs without breaking (e.g. if you buy a cheap tool built with cheap materials it might not last till the end of the first day, particularly if you are doing heavy work)
  • Sharp tools put less stress on the tool and less strain on YOU the user.
  • Long handles give you greater leverage and increased reach, putting less strain on your back and other parts of your body.
  • When you pay more for a tool, you are usually paying for long hours of thought which have gone into its design. Tools which do the job better and more easily are generally the more expensive ones.
  • If your work is heavy, your tools are likely to be strained more  you will need better quality tools.
  • Metal tools made with stainless steel or aluminium do not corrode like those made with other metals.

Tool Maintenance
Looking after your tools is very important. If you look after them then they don't have to be replaced as frequently. Tools in good condition are easier to use, they are also generally safer. Some simple reminders are listed below:

  • Metal: to prevent rust or corrosion metal either needs painting with a good metal primer, or regular coating with oil (After using, clean and wipe metal parts with an oily rag).
  • Sharpening: sharp tools require less effort to use and because of this there is also less strain on the user. 
  • Washing: If tools are kept clean they are less likely to corrode or have moving parts seize. This also reduces the likelihood of pests and diseases being spread from infected areas to uninfected areas.
  •  Storing: by keeping your tools stored properly means they are less likely to be damaged, lost or stolen. Tools left lying around can also be dangerous, particularly if you have young children, or they can be used by burglars to break into your house, garage, sheds.  In larger rooms or buildings, tools may be locked in cupboards or inside a caged area to provide added security.

Tools and equipment for mechanics work fall into three categories:
1. General Equipment.
2. Hand Tools.
3. Power Tools.
