The kink trick worked and leaves much more in the way of a turning circle. Next step is fitting the pick ups.
Not the clearest photo but it shows you the kink in the brake rod.
Taking a leaf from JB’s book I also added half nuts and tube to represent the adjuster – I shouldn’t have but I couldn’t resist adding the detail.
I also thickened up the pivot on the opposite side in line with photos in Hooles NER Locos book and added a filed down cast crankpin nut.
