Have you got any more photos of the spring that holds the hook up? Maybe also some photos without the rack so as to show the pinion and hook underneath. I am having trouble work out how to get the hook to not drop drown. Thanks for sharing the design files, I am looking forward to fitting them on several of my locos.
