@fay69 ss rope looks like brake cable-as long as theres a mesh wrap under your coils around the part that protrudes above the deck you'll be fine,especially if your little bro's been using it-should be nicely broken in.
There is a mesh wrap. It is actual brake cable though He has a garage and just cut a length. I didn't believe him at first but he showed me how he'd done it. I think it looks a little bit coarser than the ss rope I've looked at online.
