This is a question about finding a tool - I hope I'm in the right place? I have an old Singer Sewing machine, which had one of these springy steel rings around the base of the lamp, and I had to open it up and solder the wire inside. It was easy enough to get off, but how do I put it back?
The ring looks like the picture below - I have been looking for some kind of pliers, but they all seem to be meant for the kind of clip the has little eyelets. Is it possible to put back without special tools?
