First topic message reminder :
I have noticed that quite a few crossbows I see on here have pulleys at the limb ends Pulleys are not cams,which give mechanical advantage,and make cocking easier,all a single pulley can do,is change direction,no mechanical advantage.constructing a bow limb with a pulley on the end is much more difficult.so what am I missing,why is it done?.I am working on the assumption that nothing is done without good reason,so if any of our knowledgeable members can enlighten me,I would very much appreciate it.
