im an engineer at Ti-Lite where we build pretty much the cadillac/corvette of wheelchairs. we specialize in titanium but also build cheaper aluminum chairs. most of the time im at a computer working on Solidworks or Autocad but i also do a lot of wrenching and training on lathes and mills. its a pretty cool job and i have access to a lot of cool tools. most of the chairs we build are custom built everyday ones but we build a lot of sport chairs like this one below is for wheelchair tennis.
