Having watched 'Guy Martin's Spitfire', I've 3 questions re: the fastenings used.
a. How are the different coloured 'place holders'(?) used and what is the significance of the different colours?
b. I noticed that the rivets used were similar to ones I found amongst my grandfather's* tools, they appeared to be of anodised metal and different colours. Were the colours linked to the above?
c. I understood what the definition of "FT" is when securing the propeller
but did 'they' use torque settings for the building of the aircraft apart from the maintenance of the Merlin?
Any comments gratefully welcome!
