This old timer at a job site in Cleveland made me rethink my whole approach to rigging.
I was setting up a tricky lift for a steel beam last month, using my usual nylon slings, and he just shook his head and said, 'Kid, for that angle, you need wire rope chokers, or you'll see a 40% drop in your safe working load before you know it.' He drew the math on a scrap of plywood with a grease pencil, showing how the sling angle changed everything. Anyone else have a simple rigging rule they learned the hard way?

That 40% drop is why I always eyeball my angles now.

Just mark your start and end points with tape, the line between them is your angle.

Wait, you eyeball them after that?
