Additional hint: use `proper' Araldite (the stuff that takes 24 hours to
cure) rather than the rapid setting stuff.  The proper stuff is 10 times
stronger (35MPa maximum bond strength rather than 3.5MPa), but that
doesn't matter half as much as the fact that I've had rapid Araldite
bonds fail at 100�C and `proper' Araldite hold at much higher
temperatures than that.  Avoid anything like Superglue, Copydex, and so
on.  It's worth keying the surfaces (rough them up with a bit of wet and
dry and be careful where the dust lands) and then cleaning them with
meths before putting the glue on.
