I have a Gitzo G1327 camera tripod with carbon fibre (CF) legs.

The thread at the top of one of the legs where it screws into the
platform(?) head of the tripod has partially stripped and cannot be
tightened. *The effect of this is that loosening the twist clamps for
the lower sections of the leg in question turns the leg at the head
end.

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?

The leg can be fully removed from the socket which would allow for
roughening of the mating surfaces of leg and socket.

I do have some JB Weld if that would do a better job that Araldite.

Any tips or solutions would be gratefully received.

Carbon fibre is in fact laid up in either epoxy or polyesther resin in
a mould. Ideally would be to use a similar resin as a glue. Epoxy is
the commonest.
The problem with adhesion arises when the finished product has been
polished or has release agents from the mould still on the surface.
If any form of silicone polish/release agent/lubricant has been used
(as is common) repairs are difficult because a bond cannot be
achieved. The silicone gets right into the resin which is in fact
quite porous.
You need to abrade the surface and try. If it fails it's probably for
this reason.
