Having fun modeling these things from the late 1800s. Here’s a “rope pulley” which is a little over 5 feet in diameter. These were used with cotton rope to drive mills for spinning or fabric production. This one would have had four ropes each of which was spliced end to end to make continuous loops. Very quiet operation.

Here are a couple of similar wheels with a single cable wrapped around multiple times and spliced end to end to make one continuous loop. To get the cable from one side of the the large wheel to the opposite side of the smaller wheel, the cable runs up over the upper wheels which are set at angles to provide a good lead.
