When rigging a R/C model yacht we use a similar method but have a sail winch at the end driving the cord from in to out and one thing that might be useful to you is we put a small spring in the cable to keep the tension on the line. Great stuff.. looks great cant wait to see the rest of it when it is done..
I think youtube recommended this to me because ive been listening to John Frusciante's PBX Funicular Intaglio Zone. Thank you for letting me discover what Funicular means and expanding my vocabulary.
