The Cable Guy
The next step was to begin rigging up a pulley system leading from above the hole in the ceiling apex, back through all my crawl space, all the way to the access point above the closet.
At that point, a hand-winch, bolted to the support, would allow the sculpture to be hoisted or lowered, and tied off as well.
I unrolled the string all the way back to the winch, added a few feet, then cut it and let it fall through to the room below.
After crawling back out, I measured the length of the string so as to know how much plastic-coated steel aircraft cable to buy (about 60 ft).
Then, crawling all the way back in, I snaked an end through the hole, rigging it through all the pulleys back to the hand-winch, to which the end was tied.
A few cranks of the handle served to tie it off.
I checked the tension through the pulleys by adding a 15 pound weight on the other end back in the room below.
Everything seemed to work, anyway.
Thankfully, all this was accomplished without a single misstep down onto—or through—any sheetrock.
