You are correct Jesse.
If you watch the video you will see that we are swinging the pieces away from the roof. I am about 25 feet away from the rigging line if it is hanging directly below the block.
Rather than putting the groundie in charge of getting me back the rigging line, I implemented this moving pulley technique that I learned from watching one of Reg's videos. This technique is great!
I diagramed it out on a piece of paper-hope it makes sense-hope you like my lack of artistic skill.
In the diagram, the leash is tied to a moveable pulley that is connected to the rigging line. Before I make the cut, the pulley is above me attached to the tensioned rigging line. The pulley is attached to a leash that it connected to a branch within my reach so I can pull the rigging line back to me after the piece has been untied from the rigging line. Does that make sense?
As the cut swings away from me the pulley allows the rigging line to run through it. As the leash comes to its end, it floats on the rigging line as the rigging line hangs directly below the block.
Hope people can follow my explanation...
