The trick of hanging the load from a single line, and gettingmore than the load's weight in the line tension running around on the load, seems ver elusive to many.
It really works and once the extra force loaded point(s) are on the load, leveraged apart, leveraged by angle and bend etc,; the next idea is to use that to advantage rigging. Sometimes, putting the better choice of hitching on the load, is even easier, and you can take more. For one thing, presetting with a line thru a crotch can be done from the ground even, and used several times before rigged out by just hitching the end to the butt, for the far point is already rigged, and now torqued! But to see when to use it, and it is easeir or the extra power helps, ya got to walk the learning curve!
Here is another do-it-yourself pruf with even fewer items. You set the rig as before, only add a line over the support and tied to clevis, but let it hang loose on the control side. Now, the original line does the mayhem pattern of a DWT on the load as it pulls. But pick up harder on the new line, to let the mayhjem rig relax, and it hangs like a regular tieoff, no 'mayhem'. With your fingers, you should be able to tell that the line holding the clevis is tighter when mayhem is line is used. Taken a step further, you can rig so that a 4/1 pull likewise happens on the clevis with the slick throwline powered by the load's weight that this all mounts on. i guess that would make a heck of a nut cracker hanging from the ceiling; pick up the load, place nut in, drop and 5x1 breaks nut open!?!
