You saw something “Practical” here?! 
;D :
Looking for advice on the best way to unlay nylon rope.
Many are no doubt curious about Why … ? --as am I?!
So, does anyone have advice on how to do this better?
Seems to me that the ideal solution is to somehow get a rope-making (laid)
machine to run in reverse, putting the appropriate torsion to rope/strands.
My mind is otherwise running to somehow attaching (temporarily and
variously located) strands to swivels up high, suspending weight on the
rope, and pulling down through it with a bar to hasten the unlaying
– hoping those swivels allow the torquing of strands to be relieved.
