Could you double-check my use of on-line calculators to determine
the
column buckling load of a pinned-end chain link fence post 1.90"
OD,
1.77" ID (16 gauge) and 96" long as 4900 lbs?
...
I get ~1600 lb and that's assuming fully axial loading with no
moment...will be significantly less with side loading. Seems on
first blush at a reasonable number, 8'L/2"D is a pretty long and
slender wand...and 16 ga ain't that stout.

I've put about that much load on a tripod of 1-5/8" fence posts, to
proof test it. Normally it carries a 1/4 ton HF hoist.
Originally I used wood posts and happened to hit the buckling limit
exactly -- the post would remain at whatever deflection I pushed it
to.
Today's hoist project is to pull up some bushes and saplings.
