Polycord Problem

[Ankit S.]

We are using 3/16 OD hollow yellow polycord for our ball lifter (McMaster 6567K56). After testing it and it working barely with almost no tension, we decided to cut off about 5% to tension it. This looked proper, but a few of our connections were failing randomly when they were not being run.

We think we may have over-tensioned it and will probably need to add some polycord to lengthen it, but before we do that and add possible failure points, are there any tricks to use to keep the connections from failing?

I have seen some posts about polycord welding, but im not sure if that works with hollow polycord...

Thanks!
