A practical question: I am rebuilding electrolytics now.
One of those is a guy with the body of a nickel-plated copper (or so it looks) and not an aluminum; the peculiarity of it is, it has a large diameter thread to bolt to chassis and it is some sort of backelite or thermoplastic, and a thick aluminum rod going through it with a thread for the electrical contact is somehow backed into that plastic.
The thermoplastic started crumbling before and when I tried to dislodge the rod a piece of plastic cracked and came of, and the rod itself eventually broke.
Now I am trying to work from inside but to no avail, it is extremely intransigent contraption.
If I choose to get rid of plastic altogether I lose the remainder of the thread that goes through the chassis so I won'ot be able to bolt the cap.
I though of mounting a clamp to the chassis that would hold the cap but there seems to be no space for it.
Any ideas? Anyone encountered these caps before to know what to do with them?
PS. Oh, I photographed the internals of that cap before I discarded it, they are beautiful - a spiral fully covered with some copper salt (it was all blue), looks like something from an alien movie. The cap was fully dried.
