Flat Car: Part 2 - Friction Drive
I decided to go with N20 DC motors for the Flat Car. They are not as thin as I would like, but they are strong and readily available and I need to start somewhere.
I put a friction wheel on the motor and wheel axel. The hinged flip up motion brings the spindle in to contact with the wheel axel and the wheel turns.
I ended up using pinch rollers for the friction drive. These pinch rollers are usually used in tape recorders. More to come.
