I've been fighting with rope hanks, trying all of the You Tube methods and ending up with tangles. I was laying awake last night and it popped into my head. I use heat to stop rope from unwinding when I take it off the rope walk. Why not put my loaded hank jig in the oven, maybe it will lay right afterwards. It does!! 5 mins at 325f and the hanks are the perfect shape and don't sproing. Minimum glue is needed because the thread has taken a set so there is no strain on the glue. You can even put it in the oven with wet glue and in the 5 min the glue is set. They are maybe a little too perfect as they all look the same but I'll work on that. One caveat, I think it will only work with polyester rope. But the sproings and tangles are gone
