Back in 2008 I chose to use my tax return to design and install a zip line up on the vacation land. I worry about damaging trees, so I researched and constructed the platform to do minimal damage to the maple trees. Cable wrapped around the trees spaced by blocks of wood, and tension. My friends were leery at my design, but I assured them I built it to hold up to 10,000 lbs.. so no chance of it snapping. I also made a rope / 2×4 ladder.
The launch platform is 20 feet off the ground, runs for 250 ft about 23 seconds of flying through the trees. I custom made a bungie cord break for the bottom at only 8 ft from the ground. The riders weight actually allows them to stand up at the end and remove the harness. Cost me $450 for the wood, and hardware, 10 hours of design and building and 3 hours of installation. Three springs later.. the trees are not damaged and the cable it still tight.
I am putting in a second one this spring, all my friends have chipped in for the cost. another 250 zip from the cabin to the existing platform.
