Attempted to make the zipline work. I’ve increased its length so we get more play and sag in the rope. The seat therefore bottoms out. Raising the rope and making it as taut as possible only resulted in a seat that is too high and becomes a projectile upon getting off. While the longer ride sounds fun, unless I replace the static line with a steel cable and a static line I suspect this is a bust. Wait! I could use prusiks and a come along on the static line. Hmmm. I wonder what the tolerances are?
