You are thinking in terms of pulleys always on the outside of the band. With (...) (22 years ago, 22-Jan-03, to lugnet.cad.dev)

Some thoughts that could perhaps (with [lots of] work) lead to an iterative solution: - Select one of the circles, then choose one radius of this (...) (22 years ago, 22-Jan-03, to lugnet.cad.dev)
