           Chipping using flat chisel

           Before commencing chipping: Select a mushroom-free chisel and choose a hammer with a well secured handle.
           (Fig 1)
           Wipe off oily substances, if any, from the face of the hammer.

           Wear safety goggles.
           Install the chipping screen. (Fig 2)

              Fig 1                                             Fig 2













           Chipping process : Hold the work in a vice. If necessary, support the work on a wooden block. (Fig 3)
           Position the chisel at an angle 35° (approximately) to cut the metal in uniform thickness. (Fig 4)
           Hammer the head of the chisel by looking at the point of the chisel. (Fig 4)

              Fig 3                                             Fig 4














           Hold the hammer at the end of the handle for maximum leverage. (Fig 5)
           Stop chipping before the end of the surface; otherwise the edge of the job will break off. To prevent this, chip the
           end of the job from the opposite direction. (Figs 6A & B)
