Thanks for the replies, everybody. I've not been ignoring you, honestly. Some of us have to work on Sundays. Waah!
The threading is 1.370" x 24 tpi, which is British, yes? If I've got that right, I can't really see how the fixed cup can be working itself loose. The lockring on the adjustable side was uber tight when I'd finished with it last night. That being the case, how could the adjustable cup move either? I'll make sure the fixed cup is on properly when I try again.
So I just wrap this Threadlock stuff around the cups and screw them in as normal? It seems improbable that one tape-covered thread would mesh with another, but I gather that's what you're all saying, so I'll take it on trust. :-)
The bearing cages ARE definitely in the right way, although I admit that I had to think about that a lot before I decided on the correct orientation. Sheldon seems to be in favour of loose bearings. Alas, I don't always do what Sheldon says. Unfettered bearings just seemed like something else to add to my torment during assembly.
Finally, I did think about getting a sealed bottom bracket. Someone put me off by saying that the adjustable version was more in keeping with my bike, which I guess is true. It'd be so easy to go into a shop and buy a sealed Campag Chorus BB... I'll have one more go with this Italian antique before I throw in the towel. Thanks again.
