Wheelchair FOOTREST Jig

Wheelchairs are expensive equipments that usually consists of many complex sensitive parts. Thus, they are easily susceptible to damage and involve a great deal of difficulty during repairs. In particular, the foot rests tend to receive the most damage due to their position within the wheelchair. They get easily bent and are often made of materials that are hard to work with. Rebar is a common material in much of the 'majority world' and in Bolivia many children (teens) are taught to shape rebar into useable products as well as weld them with arc welders. A jig, fashioned out of aluminum that could act to bold rebar attachments to wheel chairs would extend their life and usefulness as well as allow for greater customization.

Dr. Nolan has a basic drawn explanation of functionality, but requires a team to develop a 3D model and then fabricate working physical models. Members will be taught the basics of taps and threading to begin and will be provided a wheelchair for testing.
