I think I have finally tracked down the creaking, which has been driving me slowly insane, to the bottom bracket. I have therefore decided to replace the offending item in an effort to restore mental stability, but would like some advice - Fitting a Campag Veloce square taper BB to a Ti frame should I use grease ( any particualt type), copper anti-seize, some other anti-seize, thread lock, snake oil, chip fat ? Park tool recommend their anti-seize for Ti frames but also say "It can sometimes happen a bottom bracket can creak where the lockring or cups meet the bearing body. To prevent this, apply a thread locking compound such as Loctite #242 to the inside area of removable ring, where it meets the body. This will help prevent any creaking in the future. With plastic rings, do not apply any thread locking compound." So where exactly do they mean to use thread lock ? Hoping you can help, all advice welcome !
