Originally the jib was going to have a single cable but that changed to a twin setup, partly for failure redundancy and partly to take out twist in the truss when its loaded.
Each end attaches to a small surface eye from a chandlers bolted onto the steel handle at one end and the aluminium truss at the other.
The rest of the hardware is also from a chandlers. The wire is slightly thinner than originally planned (2mm instead of 4mm shroud wire) but is still capable enough. The 4mm wire had a breaking strength somewhere in excess of 1500kgs, so with two of them, it would have been a bit over kill, and harder to work with. The thinner stuff is probably still way over 300kg each and even if one breaks (it shouldnt) it'll hold everything on its own happily.
The wire goes over the wooden tower cap which is screwed into the steel.
At the steel handle end a bottle screw attaches to the eyelet and a shackle attaches the wire which has been properly crimped into an eye to the screw. At the other end the shackle attaches direct to the eye without a bottle screw.
The cables sag down over the tower before being tightened.
Afterwards the wire takes the weight of the jib and adds a slight upward curve. once the camera head is attached the wire can be tweaked to give the right level of support. For now i'm running the cable slightly tight to see if there is any excess stretch and how much it'll move.
The last thing is to cut the metal brace to make room for the parallel bar which keeps the camera head frame level. One side is done, the other side needs doing and then the uprights can be attached to the pivot and the bar tested.
With a bit of luck it'll be ready for November, but with shorter nights its not looking quite as likely now.
