Step 6: Gondola attachment
Take care none of the inwards bends measure further than half of the wheel diameter, as otherwise the gondolas will hit when passing each other.
In the picture you see how the small “connection” piece is slightly bent "out of the plane" to bring equilibrium in tha direction too.
A small piece of tape put on the steel wire end is rolled tightly over the steel wire and looped rope together. Check how it fits in the pulley in the last picture. One kid operating the motor till the desired spot of attachment passes and stopping it so another can attach his or her gondola proved to be a great little game of collaboration.
