Well, shed track will have to wait for tomorrow now Ended up finishing the bracing and adding extra sets of legs to the terminus. Is all beautifully level and rock solid now. It was irritating me before that some stock would roll so now I can drop any item onto any part of the track and it wont roll away
I also used up 50 cable ties and tie anchors tidying the cable (yes, I am OTT and OCD )
