Last meeting the boys wired up new batteries to the wheelchair motor controllers and motors to confirm that the system would run as intended. They also learned to write up a wiring diagram for same.

Over the weekend, the tubes and tires were changed out and cleaned.

The bonus of having skilled mentors: when Sebastian wondered aloud how knurling was done, Jim was able to take him to the metal lathe and show him.

We now have a solid basis for some kind of motorized car. The next step will be designing the base and body.
