In my final year of school I designed a device that would allow drill operators to drill holes perfectly perpendicular to the work surface. This project which was awarded 100% was also entered into the Audi Design Foundation Awards.
To make the project a success it was vital that I model typical power drills in order to make a product that would fit the majority of drills available to consumers. Once the drill was modelled I was able to design a product that would fit the drills.
I modelled my design on the model drill, on a real drill and made the device to fit all 3 of the drills that I had at my disposal. I also manufactured a plastic version of the device in order to demonstrate the way the product works.
The device operates in a very simple way, four semicircular discs fit to make two complete steel discs around the collar of a power drill. A velco strap then clamps the discs in place aound the back of the drill. An arrangement of springs and rods run along telescopic tubes which are connected to the steel backing discs, these ensure that the drill runs perpendicular to the work surface. The assembly and workings of this device can be better understood by reading the report that was submitted in 2003 or by viewing th animation below.
