074. Two Wheel Conveyor
This turned out to be an extremely difficult toy to build. A single beam extends down into the box. In order for the box to sit squarely, the dowel must be perfectly balanced on that beam.
The pulley mechanism makes the beam a little offset from the center. And that meant trying to shift the dowel back and forth incrementally to balance the box. The photograph shows how close I got after a half hour of work.
The illustration is also quite misleading. The shortest dowels provided are much too long. The illustration implies that they extend only a little out the other side. Not so. I photographed the toy at an angle that hid most of the excess. But if you look carefully you can see a little bit of a dowel extending out the back.
