Refurbish used wheelchairs for charity

Volunteers with Hope Haven International refurbish used wheelchairs for distribution to people in need in developing countries.  The work includes cleaning, simple mechanical work (if you can unscrew a bolt, you can do the work), greasing bearings, and optionally more complicated mechanical work.  Preferred work times are Tuesday and Thursday mornings, but other days or times are possible.  This particular listing is for volunteers who will regularly return.  See a separate listing for one-Ime opportunities.
