The way it was… UB415 at Rolla Vichy airport, Missouri back in 2001.

The process is called metal spinning, where a disc of metal is spun in a special lathe, over a wooden former. Much info out there if you Google the subject.

The large item in the middle with the tapered shank, is the outer aileron hinge fork- fitting.

Good to see that Auntie Beeb are spending the TV Licence money on something decent for a change.

Rather bizarre though to have an aircraft registered in their name, presume they are financially involved in the project?

Quite a simple matter to shift the craft out of the hangar..just so long as you have the gear + mucho man-power! The craft was mounted on small wheeled bogies and was winched out on sections of temporary railway line.

However this entailed jacking the whole thing up to fit the wheels. The jacking set up, a complex hydraulic pump unit that operated a series of jacks at each corner, tricky business to make sure the whole craft was lifted evenly. The jack system not a permanent fitment to the craft, had to be heaved aboard and set up each time a lift was required.

Thought it might of been Bov..thanks for the confirmation!

You might well find the Christchurch civil VHF frequency in an old edition of Pooleys Flight Guide, (well known pilots publication). The first edition came out in 1964, maybe someone out there might have a dusty old copy?

Whilst not quite the era you are interested in, some of the frequencies tend to be long standing, e.g. Bembridge, here on the IOW has been on 123.25 since the early 1960s.
