TRIPPING THE RIGGINGS
Tripping the riggings off the stack after the job is completed takes only the work of a few minutes. See to it before making the last trip up that you have that necessary appliance with which to save you a few unnecessary trips up and down.
Take a small steel bar about ΒΌ-inch in size and bend it into the shape of the letter S. Judge the diameter of the band on top of the stack; make the hook so it will fit snugly on top. This hook should not be over five inches long. After placing the trip hook on the stack, take your handy line, lay it on the hook, tie the end of your line in the eye of your stack hook, then tie up about two inches above the eye in several places. The last two tie-offs will prevent the stack hook from falling to one side.

After leaving the stack, have your helper tie the handy line away from the stack. This flopping back and forth will annoy you while at work. After you have finished and are ready to trip, twist the rigging until it is twisted all the way to the top. In doing this twist the rope so that the stack hook will turn out and away from the trip hook. This is important. Leave slack on the riggings at the same time. Do not let it untwist. Then take the trip line, pull steady on it, until you see the stack hook raise up and over the stack. Then lower on the trip line until you see the stack hook is off and below the top of the stack. Then let go of the riggings so they will untwist; lower away; untie the handy line from the block hook; then pull one end of the handy line to the top. It will go through the small S up there and fall to the ground, leaving the small S hook on top of the stack.
