That's a very good list. My mum would add to that 'after hours of work and when the sky is dark and you're in your pyjamas you should not attempt to work on paddle steamer models.'
That's what I got told after I sliced open my finger when cutting towards myself when trying to remove a nasty jutting out piece of plastic on a set of trial paddlewheels.
Yes it was late at night!
Mum also won't let me work on my models or Grebe when I'm sick...again she worries about me removing some of my limbs!
