Keith,
Pulleys are Pulleys and Cable fasteners are Cable fasteners. The easiest way to understand the rules is to understand the intent - use the objects as intended and don't read too deeply into it. Pulleys transfer motion and magnitude, Cable fasteners attach cables to objects. Just because that object being attached to may be a pulley doesn't make the pully a cable fastener anymore than the Cable fastener is a pulley (2 different functions). Hopefully, you won't have to be forced to improvise by making pulleys out of other material - think of alternative ways to achieve the same outcome. Surely they exist, Be creative - besides whats so bad about improvising! That's sometimes where the best ideas come from. Its amazing, all the different ways of doing things you will think of when you have to.
