This has probably been beat to death by now, but I want to replace the lift cables on my pop up before anything else breaks. I have already found replacement pulley wheels. Home depot sliding door wheels, metal ,with ball bearings. Slightly bigger than the original wheels but I'm not afraid of modifying the pulley mounts. Already done a couple. No more plastic wheels that lock up and burn through the cable. Now I am on to the cables. My main question is: am I better off making my own? And if so how long should each cable be? In theory if I can pre-make them than I can be ready to replace them immediately once the weather gets better. Or should I just buy the cables premade? Thanks!
