An added comment.
In most applications it would not even be necessary to use pulleys for the fixed points on the mechanism that I pictured. One could just replace the fixed points with two hard steel pins. The thread on a sewing machine for example traverses through numerous holes, eyes and metal guides. Michael Karas |
