Steam Oil,
I personally wouldn't use superglue, even one of the flexible types. You will have all sorts of things whizzing around on your machine, oils etc., and it might not hold permanently.
I would go, if you want to go down that route, with a slow set epoxy. But only after both jointing parts have been both mechanically and chemically cleaned (sandpaper and spirits).
I have also found that the Acrylic type of epoxies are great, such as Stabilit, which is available all over the continent, but you only have about 5 to 10 mins work time before it starts to set. But the bond is one of the best I have come across without going into industrial adhesives, where, if you are willing to pay for it, can be almost as strong as a welded joint.
Hope this helps.
