Okay so here it is.
Let’s say we are going to be rigging out the lowest limb. You’re going to secure the end of the rigging line onto a higher branch above it. Clipping it onto itself with a carabiner is fine, or a knot whatever.
Now you’re going to pick another spot and set up a pulley and run the other end of the line through, but leave some slack so you are essentially left with half a loop.
Now hook a sling onto the branch and clip onto that “half loop” of rigging line with carabiner.
You’re going to hold the end of the line coming out of the pulley and make your cut.
Lower the piece, pull the rope out of the pulley and out of the carabiner / sling and pull it back up and repeat the process with another sling.
It’s sort of almost like span rigging.
