Hi folks,
I have an old darkroom lamp from the 1960s. It originally had a red bulb to protect the black-and-white film. I like the style, so I'm converting it into a desk lamp.
It has a pair of ball-and-socket joints in the arm (ball is about 1/2" diameter, and the power cable passes through the centre). The joint is held stiff by an internal compression spring, but this isn't quite providing enough friction.
I had wondered about fitting a stiffer spring, or trying to stretch the spring a little, but I'm not sure how easy or wise this is.
I'm now thinking of squirting some tip grip liquid for screwdriver bits into the joints instead. Something like this:
The joints are made from hard brass.
Thanks!
Best wishes,
Chris
