Zipline is complete and functional. Did a 250 foot run starting from a deer stand at the edge of my woods and terminating near the edge of my pond. As this was my first project I kept the pitch and height pretty mellow plus I have two young kids and I want them to enjoy it. I made it from 250 feet 1/4" 7x19 galvinized cable, 2 18" x 5/8" eyebolts, 2 18" x 3/4" turnbuckles, a 16' deerstand, a Petzel climbing harness and trolley, an adjustable nylon sling and 3 old lawnmower tires for a stopping system. Most materials purchased at Fehr Brothers rigging and Karst Sports. Hope to build couple more now that I have the technique down. Video links follow(sorry for the sideways orientation).
