(Somewhat modified from the Healthlink manual.)

The Healthlink wheelchair is built onto an ordinary child’s wood chair. Measurements should be adjusted to the child’s needs.

Chair with arrow pointing to seat.
A webbed plastic seat lets air move through it and can be easily cleaned.
Bicycle wheel.
It uses standard 20” x 1¾" bicycle wheels and axles.

Basic carpentry tools are needed to build this wheelchair. It can be made in one day by someone with basic carpentry skills. The local blacksmith may be able to help weld together the wheel supports if you cannot. It is easy to add positioning aids or make other adaptations.

BACK VIEW

This backward extension distributes weight better and keeps chair from tipping backward on hills.
Two back casters are more stable and make it easier for the wheelchair to go up curbs.
