|
| Use a scriber and try square or a straight edge, to mark out the surface of the material. If steel / aluminium is being cut, consider coating the surface with engineers blue, so that the scribed line can be seen easily. | |
|
| Place the material in an engineers vice. The junior hacksaw is held in one hand and then pushed forward (the teeth of the blade face forward, away from the handle). The ‘cut’ only takes place on the forward stroke. The first few ‘cuts’ should be taken with care, until a grove is cut in the metal, which guides the saw blade and then more rapid sawing can take place. | ||

||
| After cutting the material (especially steel / aluminium), remove burrs by filing with a hand file. | |
