The pole of our much-repaired Miroco floor lamp screws into a weighted base:
Because the lamp has a big nut apparently holding the pole socket to the base, I figured a dab of threadlock on the pole or the base would solve the problem: lock the pole to the socket, then remove the nut to disassemble when needed. That turned out to be a Bad Idea™.
The socket is a plastic part separate from the base cover plate:
A pair of keys prevent the socket from rotating in the hole:
Four threaded bosses (two visible there) hold the rim of the cover to the weight, with the socket doing the hard work.
A fender washer atop the weight distributes stress from the pole:
Another fender washer on the bottom of the weight lets the nut jam against steel, rather than soft plastic:
FWIW, the nut is either a perfect 15/16 inch or, more likely, a sloppy 24 mm.
In any event, permanently locking the pole to that socket will also lock the pole to the base, with no way to dismantle the lamp when I must once again repair it.
Perhaps a wrap of PTFE tape on the threads will stiffen it enough?
Certain better looking than black duct tape …
