6 Jan 1914. Tuesday.


Today was mostly involved with the aileron hinges. I would guess that there manufacturers mass producing suitable standard hinges at the time, but for some reason Frank decided these needed to be made specially – I’m not sure why. They would have been expensive to produce, and the machining would have introduced stress raisers that are far from ideal.

Sketch 539 is of the fuselage front end, and differs very little from the production version. I think it was drawn to show exactly how the lower wings were intended to fit to the fuselage, and was, I suspect, prompted by a question from the shop floor as they started to assemble the fuselage.
