Water Pump
This project
is an adaptation of a pump developed for shallow wells in Zimbabwe.
The building elements are: head pulley (made by splitting an old
car tire, reversing it and sewing it back together). head support
and crank (manufactured by a local carpenter), washers (pressed
out of old flip-flops with a heated can, as learned from a child
making wheels for his toys) and the pully at the bottom of the
well (manufactured by a local welder). It was important that the
building elements be distinct, as they required some adjustments
when assembled in the well.
