So I'm looking for a new barrel and probably a new tip [1] but I just
wondered if anyone could confirm the part number for the barrel
please? I believe it's '0051031199' but I thought I'd check before
ordering.

I also found the old-style dead element and some new-style elements and
barrels. The new-style barrel does go onto the old-style element, but
even with the thread tightened all the way, it does not grip the
soldering bit tightly so it wobbles and probably doesn't conduct heat
all that well. I'd say it is not usable like that.

Hmm, my replacement barrel arrived today (next day, thanks Rapid
Electronics Ltd g) and if screwed on finger tight, the tip seems to
be pretty solid, so I wonder if there is still more to it (like the
tip dimensions)?

The other question is do we generally put any sort of thermal / anti
seize paste on these things please, or would pretty well anything
simply burn off?
