Looks good. A few minor points/thoughts...

I would put a picture of the right tool somewhere near
the beginning or the article, not just the wrong tool,

I did (sort of) by linking to the TLC site. But yup, a piccie can be
arranged.

and perhaps a pile of different size crimps.
(You could add pliers, mole wrench, and hammers to the
picture of wrong tools.)

Hacksaw ;-)

"[screwed terminal] method is only acceptable where the joint
will remain accessible for future inspection and maintenance,
since screwed terminal connections can become loose over time."
Please provide a citation for such a justification.
(I don't believe that accurately describes the reason, and
Wiki's need to be accurate when giving facts like this, or
make it clear this is speculation of the author.)

Which bit are you querying: that they come loose in the first place, or
that being the reason they need to remain accessible?

In the sample damage you've shown, I would probably not have
cut and rejoined an undamaged conductor.

I may lose the "before" picture since it adds nothing to the story I am
trying to tell really.

A blue crimp is the wrong size for the earth conductor. You
could use one if you folded the conductor double, or the
crimp has no central barrier such that you can push the
conductors through to overlap and crimp both conductors
together. Whilst in practice a blue crimp probably would
work OK as you have done, an article explaining how to
crimp probably should get this right.

I did think about this for a while, given that red is a better size
match as you say. However if you look at the spec I listed for blue, it
does show the minimum wire CSA as 1.04mm^2 which is acceptable on the
1.5mm^2 CPC in the 2.5mm^2 T&E I was illustrating.

It's probably worth explaining crimp sizes and colour
codes. Otherwise someone unfamiliar with them could well
think they need a red one on the live, a blue one on the
neutral and a yellow one on the earth ;-0

Good idea sir, I shall nick that!

I think a table etc is a very good idea. (might swipe some piccies to go
with it)

This is getting to the really minor nit level, but when I
join T&E, I usually stagger the joins even more than you did,
such that none of the crimps overlap at all. Then the cable
thickness doesn't increase as much at the join, and it can

;-) Yup so do I normally!

Only having cut them a tad short and already taken a few photo's I CBA
to start over.

This, like pipesoldering demos, is the bench demo. In real
life (TM) you'll be doing it in some corner where you can't
both feel and see what you're at the same time, you can't
swing the crimp tool into the right position and get any grip
on the handles, and there's only 2mm of conductor exposed
from a 3' thick bomb shelter wall ;-)

BTSTGTTS.
