=====Introduction=====

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.

The illustration gives some main dimensions for guiance but these are not critical and can be varied to suit the drill used and the materials available.

The better quality drills always have two '''[[:Category:Gears|Pinions]]''' and the '''[[:Category:Gears|Gears]]''' are fully enclosed. These tend to be easier to operate and turn more smoothly - and they avoid the danger of trapped fingers!

=====Hand Drill Stand Construction=====

Typical assembly details of a stand are shown together with some notional dimensions for guidance. The main elements are: a base large enough to ensure stability; a vertical support structure firmly fixed to the base ''(see '''[[:Category: Wood Joints|Wood Joints]]''' for suitable constructions)'' and a sliding block to which the '''[[Hand Drill]]''' is attached.

The vertical support is arranged, by means of a spacing block, such that the drill overhangs to provide clearance when drilling holes in the centre of wider pieces of material.

The most critical element is the sliding block assembly. A variety of materials and constructions can be explored but the aim is to ensure the drill can slide up and down easily without undue 'waggle'.
