We have used various materials for clotheslines, mostly rope or stuff meant for clotheslines. In most cases they work fine, sometimes sag in rain or cold then contract when dry. We have a pulley system so we can stand by the door, out of snow or wet, put clothes on the line and then send all the clothes out to dry. This works great when the knot is in the right place, as the knot won't go thru the pulley! I've tried using 3-strand rope using a long splice, but stretch was still a problem. I've looked at all the fancy clothesline hardware and couldn't find anything to join a clothesline into a loop that would still go thru a pulley. So, I decided to come up with my own solution. I chose coated steel wire rope, no stretch, won't stain clothes, and weather resistant. I still couldn't find low profile couplers, so what I did is this:
I Put the pulleys on a slightly longer long piece of cable and installed the line, then tightened the line and marked where the ends would meet, added a half of an inch, and cut the cable.
I bought a ferrule and stop set for crimping cable, one size bigger than the cable, I have 1/8" cable, so I used a 3/16" stop, The thing you crimp on one strand of cable. I increased the chamfer on one side to help later. Then slid the stop onto the cable as well.
Then I stripped 1/2" of coating off both ends and sort of unlaid the wire so the strands were straight and loose. Then pushed the 2 ends of the cable together so the strands were evenly mixed and the cable looked like it lined up across the gap. Then forced the stop over the married ends. The fit was tight but a little coaxing got it all in. You could see the strand ends on both sides of the stop.
Then since the stop was 3/16", I crimped using that spot on my swaging tool, followed by reswaging using the 1/8" spot. I did multiple crimps across the stop so the stop was evenly mashed. This left small wings on both sides of the crimp which I then ground off, smoothing what was left of the stop.
This left a relatively low profile connection, well pressed, and sort of working like a Chinese finger puzzle. What's great is that the connection easily passes thru the pulley!! I have a long threaded hook on one post so I can tighten the loop. Hardly any sag and is holding up great!
I smothed the connection a little more after taking the pic below and I may coat the connection with epoxy to keep moisture out.
I'd love to hear if anyone has come up with something easier or cleaner to make a connection that will go thru the pulley.
