THE HACKSAW

THE HACKSAW

 The hacksaw is used to cut steel and other metal.Blades are supplied in two lengths, 250mm and 300mm.

 Two types of hacksaw blade are generally available. High Carbon Steel blades are used for general cutting/sawing. They do not last as long a High Speed Steel blades.

One hand holds the hacksaw handle. Notice how the index finger is used to support the handle and also points in the direction of cutting.

The other hand holds the frame, near the wing nut. Cutting/sawing should be carried out close to the jaws of the vice. This ensures that the metal does not flex or bend under the force of the hacksaw and the sawing motion.

Cuts of File

FILING PRACTICE

 Filing practice

Hand files are normally held in both hands. The file is held flat against the surface it is to cut / smooth. The file is then pushed forward and it cuts on the forward stroke. It is then lifted away from the metal and returned to the starting point for the next push forward.
This is called ‘through filing’

If the surface produced by through filing is not good enough - the next stage is ‘draw filing’. The diagram above shows how the file is held during this process. The file is held in both hands by the blade and pushed forwards and backwards along  the material. This will further smooth the material.

If the surface produced by through filing is not good enough - the next stage is ‘draw filing’.
The diagram above shows how the file is held during this process.
The file is held in both hands by the blade and pushed forwards and backwards along
 the material. This will further smooth the material.

The safe edge of a file does not have teeth. This is extremely useful when filing in corners as shown in the diagram below. The safe edge is placed into the corner and because it is smooth it does not damage the surface of the metal.

Wanted Diesel Mechanic Technicians

                                   TRY-SQUARE

The engineers try-square is composed of two parts, the stock and the blade. 

A typical use of an engineers try-square is to mark out material for cutting/shaping.
