__TOC__


=====Design Brief=====

Young children may have difficulty drilling holes which are truly '''[[Squareness|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 Drill|Hand Drills]]'''.
* Visit local primary schools and discuss the problem of drilling holes '''[[Squareness|Square]]''' into sheet materials.
* Observe young children drilling small holes in sheet materials.
* Find out about '''[[:Category:Linkages|Linkages]]''' which may provide a suitable parallel motion ''(e.g. [https://en.wikipedia.org/wiki/Parallel_motion '''James Watt Parallel Motion Linkage'''])''.
* Research '''[[:Category:Wood Joints|Wood Joints]]''' as possible methods of creating the main structure.
* Research components available which may assist.


=====Ideas=====

* Try different '''[[:Category:Wood Joints|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.

=====Testing and Evaluation=====

* Re-visit a local primary school and observe young children using your Hand Drill Stand
* Does it help them drill holes '''[[Squareness|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=====
[[File:IrisDiaphrams.png|400px|right]]
* 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 [https://en.wikipedia.org/wiki/Diaphragm_(optics) '''Iris Diaphram'''], as used in camera lens to change the aperture size, as a possible approach to a solution.
