I have successfully made several ceiling hoist points to hang upwards of
1000 lbs (yes, one thousand pounds), using 5 feet of SuperStrut laid across several ceiling joists. Doesn't weaken the joists with drilling or screw- driving. Doesn't flex or crack the drywall under load.Lay strut across joists in the attic. Drop 1/2 inch threaded rod through a
1/2 inch hole in the drywall, fix with washer and nut on the top (above the strut) and the bottom (below the drywall). Use a threaded rod coupler to attach a 1/2 inch eye to the end of the rod. The rod can project as little as 1 inch down from the ceiling, and you can just unscrew the eye, leaving just a bit of rod when you need to minimize the appearance. You could also make a cover or other hiding device and paint it to match the ceiling.See my page:
