Just pinched this off a board in the UK that I thought might be of interest particularly for those who have cause to stick things back together.
The author is apparently "in the Trade" and passes on a bit of info I wasn't aware of.

"It might be useful to say that cyano's (superglue) need moisture to cure. Epoxy (eg araldite) doesn't. Just breathing on surfaces before using superglue can help. Also note Araldite benefits from some heat to complete cure; and needs very clean surfaces. Detergent-cleaning is preferable to white spirit or solvents. And never be tempted to add some extra hardener to speed up Araldite curing; it doesn't work like that!
