That Guy With The Face
Been having a rough go of it, but carrying on. I've been trying to learn about "reeving," which is the manner by which rope or wire is thread through pulleys; usually ones with multiple sheaves, such as with blocks. It's fascinating how one can gain greater mechanical advantage by simply threading the rope in a certain way. I have a pair of double sheave pulleys that I hope to make a video with. I need to hone my skills adding up the mechanical advantage first. Richard Mumford had a pretty helpful video that I watched awhile back. I'm pretty sure I remember him saying that you just add up all of the legs and with the final leg, if it's being pulled away from you, you don't add it; if it's being pulled towards you, you add it. I watched this years ago, though, so don't quote me. I recently discovered the joys of "piggyback-ing" on pulley systems so that the actual system doesn't have to extend to the load. "Z-Rigs" are interesting in this regard, too, but manages to accomplish this with only one rope.
EDIT: I think there's supposed to be a 90 degree twist in this system which is hard to show on a table.
