Apart from the ruddy noise (!), it was quite fascinating watching this fella today. I could watch people work for hours ;)

I have no head for heights whatsoever, so was mesmerised by his.

In Extras you'll get an idea of scale (he is very high up - so the lengths he cut were taken off on the zip wire thingy) and how far he got!

Not finished sadly, so there will be more noise tomorrow...
