Hand Drill Stand Project

From DT Online

Design Brief

Young children may have difficulty drilling holes which are truly Square to the surface (e.g. of a disc to make a wheel). A simple Jig can be made which supports a Hand Drill within a sliding frame to assist. In use, one child operates the drill and another holds the work-piece to be drilled.


Materials Available
  • All materials and sections commonly available in a secondary school D&T Department
  • Clips and fittings to hold the hand drill in position (e.g. plumbers' pipe clips)
  • Additional components as researched and identified (e.g. telescopic drawer slides)


Considerations/Research
  • Measure and examine commonly available Hand Drills.
  • Find out about the D&T Resources used in primary schools.
  • Visit local primary schools and discuss the problem of drilling holes Square into sheet materials.
  • Observe young children drilling small holes in sheet materials.
  • Find out about Linkages which may provide a suitable parallel motion (e.g. James Watt Parallel Motion Linkage).
  • Research Wood Joints as possible methods of creating the main structure.
  • Research components available which may assist.


Ideas

  • Try different Wood Joints to create a main structure
  • Explore how a slide can be built up using standard sections
  • Consider using components such as a 250mm drawer slide to guide the vertical motion.


Design Development and Construction

  • One solution with some typical dimensions is shown for guidance.
  • Consider other ways of supporting the vertical sliding block
  • Consider how the vertical sliding block can be fabricated - or substituted by a ready made slide.
  • Think about how the vertical motion can be provided by linkages rather than a slide.


Testing and Evaluation
  • Re-visit a local primary school and observe young children using your Hand Drill Stand
  • Does it help them drill holes Square to the surface of sheet materials
  • Are young children able to use it?
  • Do young children enjoy using it?
  • How much would it cost to manufacture?


Further Work

  • Consider how to design and make a simple Jig to hold the work whilst drilling discs to make wheels - ideally one which 'self-centres' the discs.
  • Research Iris Diaphram, as used in camera lens to change the aperture size, as a possible approach to a solution.
