I understand the Donald was ferried to horsepiddal in a Sikorsky Sea King
helly co Peter; fairly safe by now as it is well over 40 years since I
machined any cuffs* for these birds whilst working at Westland Helicopters.
Dunno what happened to the rest of the message but I went on to explain
that the cuffs are the components that attach the rotor blades to the drive
shaft in such a way that all the control functions for the blades are
possible. In the case of the Sea Kings, the castings are so heavy before
machining commenced, we had to use a hoist to lift them onto the profile
Unfortunately, as the Westland was built under licence from Sikorsky,
I think it is very unlikely your parts turned up in their aircraft.
I say unfortunately because if your parts had been used, at least they
would have known what size they were. Until earlier this year, the USA
had two, different, measurements for their standard foot and though I
think it likely that their aviation industry probably know which feet
and inches they ought to have used. But better not remind Lockheed
Martin about their mars Orbiter, eh?
