Making A Coat Hook

Learning Objectives

Students should learn:

  • to measure and mark out steel using
    • a steel rule
    • try square
    • a scriber
    • a pair of odd leg calipers
    • centre punch
    • a pair of dividers
  • to drill holes in steel using a drilling machine
  • to remove the burr using a larger drill or a countersink
  • to file a curve on the end of mild steel bar
  • to use a vice to form a bend in steel
  • to use a jig to form a curved hook in steel
  • that using a jig helps to produce work quicker and reduces the risk of creating inaccuracies.

Resources

Each student will need:

  • a length of mild steel 200 x 20 x 3
  • a steel rule
  • try square
  • scriber
  • a pair of odd leg calipers
  • a centre punch
  • a pair of dividers
  • access to a drilling machine fitted with a 5mm drill bit
  • access to a metalwork vice
  • access to a bending jig similar to the one illustrated (could be made by the technician).

Activity

  • Teacher issues students with a length of steel bar, 200 x 20 x 3mm.
  • Students mark out their steel bar and centre punch it.
  • Students mark out the curve on the ends of the steel bar.
  • Students file curves on the ends of the steel bar.
  • Students drill the 5mm holes and remove the burr.
  • Students use the bending jig to form the curve.
  • Students bend the steel in the correct position using a vice.

Plenary Session

Students compare their work with the teacher's demonstration piece and each others'.  

Teacher asks if the coat hook would be easier and quicker to make if there was a jig for drilling the two holes and for forming the 45° bend.  Students discuss.

Students discuss the criteria that could be used to assess the quality of their products.

Students' work is assessed by their peers and by the teacher.  Name cards should be placed in front of each piece of work, then the work should be photographed by the teacher.
