This post is more of a reference for work with steel wire rope, like we use at Wheaton Labs for sunshade-hanging projects. I wanted an easily-found repository for links I'd been using for research and instruction.
Should anyone else have suggestions or valuable online resources for rigging with steel cable, please post here in this thread. Thanks!
Here's an info sheet detailing proper wire rope rigging loops with thimbles saddles, etc. along with the technical specs on torque needed to properly tighten saddles.
Here's another technical document at this link with useful diagrams for wrapping round coils and proper anchoring with saddles, and provides limited technical data.
Here' an instructional video that goes through step-by-step measurement and proper securement of saddles, turnback length, and techniques like a lap splice.
Here's another video that shows additional techniques for securing to posts, and uses different hardware like lag bolts instead of looping through holes drilled in posts.
