Due to the ridiculous size of the solar car axial flux motor that Ben generously donated, this vehicle is going to be a full sized racing go-kart, a slight deviation from MITER's smaller electric vehicles. It's probably going to weigh upwards of 150 lbs and won't fit through doorways, but it will go really really fast and accelerate like a sports car. I'm using aluminum round tubing for the frame to decrease weight, to learn how to weld aluminum, and because it's available.
After looking at many different designs for racing go-karts, I came up with this frame.
More on practice welds and crufted parts after the break.
