Wasting time with Google I have found that most people seem to use
variants of epoxy resin to glue CF to all manner of other stuff
including metal. Is this the case or should I search out some
frightfully expensive specialist adhesive?


Epoxy is fine. It's worth seeking out better grades than Araldite
though. West System etc. (try Axminster) sell a thin epoxy that you
thicken as needed with powder or fibre fillers. Mixing before filling
also gives a more reliable mixture. Even model shop epoxies are
better than Araldite, although you pay a hefty premium for small
packages.

Avoid rapid epoxies.


Ta!

Once the glue has set, investigate the possibility of fitting a pin
across the diameter of the tube to add more strength.
A pin such as a section of a nail shank or a broken drill with the end
filed/ground flush would be ideal.
