the machine has 5 pulleys but for now i'm trying to make it work with just two.

i made a gear mate between the pulleys but now i can't find a way to made the weight ( which is just a rectangular block ) to follow to rotation ...

Maybe I could draw a line , representing the imaginart cable as the path the weight should follow , but still how will the weight lift ?

I'm completely blocked ... i've tried every type of mate ... i'm missing something :s
