[QUOTE=HurriRV7;1375820 Still seems like an awfully complicated way to make a joint especially when you could us a bolt.

I guess done for weight saving purposes. The combination of ferrules, spacer and rivet, a touch lighter than a nut, bolt and washer!

Photo of a typical Hawker fuselage joint, in this case on a Fury.

The key part being the intereference fit top-hat ferrules, these normally made of S80 high tensile stainless steel. These take the shear loads on the joint, the tubular rivets really only provide a clamping effect, preventing the ferrules from moving.

Whilst it might seem complicated, Hawkers used it to great success over many years and a wide variety of types.

Hope this explains things, Chumpy.

The attached sketch shows the basic principle of tubular rivets, quite simple really.
The rivets used by Hawkers normally had the head pre-formed, just the tail getting being ‘squeezed’ to finish the joint.
Once you are ‘tooled up’ a very quick and effeicent method of construction pioneered on the 1930s biplanes (Hart, Demon etc). The rivets came in steel and light-alloy the lattter requiring to be heat-treated prior to installation.

Somewhere I have photos of actual Hawker joints will try and dig em out later.

There is an interesting 3 page article to be found in the July 1967 of Radio Models, good background detail of the construction and flying of the models.

I was the lucky guy to get a view of the cockpit, most suprised when they said yes to my request. Though an after hours vist was required, not much light so not the best photgraphic conditions, plus balancing on a large set of step ladders!

Whilst the outside may look a bit shabby, the interior is beautifully original, oozes history. As mentioned by Schneiderman the aircraft is sound, looks to have had a coating of ‘waxoil’ down the rear fuselage some time in the past.

Maybe a bit of gentle dusting in the cockpit, otherwise leave her alone..a ‘full restoration’ certainly not required.

Alan,
Interestring to hear about your hotel, BIA etc. As it happens I flew by BIA 1-11 to Athens, good service as I recall.

On the return journey we had to make an un-scheduled stop at Brussels to pick up a bit of fuel. The captain not certain that we would make it back to Gatwick!

Most passengers a bit peeved about the delay, however myself and sidekick pleased to get a few more reggies. Sent BIA a letter saying thanks..got a nice reply,,shame they are no more.

Yup that J made me look twice to!

Photo taken in 1987 during a silly spotting trip to Athens, staying at an hotel overlooking the airport, boy it was hot. Whats the latest on the Spit, seem to recall reading that the Greek A/F museum wanted to get her airworthy?..Calling Mark12!!!

Hi Wallace,
Nice images!!

Just goes to show that the person behind the equipment is the important part.
Yup love that Infra-Red thing, however unpredictable stuff. Along with the triumphs, I have had a whole load of duds, entire films NFG when the lid of the dev-tank is opened!

We should think of using it, used to dramatic effect in the flying sequences in David Leans the ‘Sound Barrier’.

Thats a cracking pic Chumpy, really shows what can be done with a simply subject.
Strange that this thread is so popular in historic, I can never get a discussion going in the photo forum!

Glad you liked it here’s another.

Forgot to mention a red filter is required, suits wide angle shots. Never really know what the end result will be, fire and forget etc!

Do Kodak still make the stuff, can you press a button on digi cameras / ‘photoshop’ to get a similar result these days?

Another factor re those ‘good old B/W’ images was the role played by those in the darkroom. Careful treatment required to bring out the best from the neg, burning and dodging, grade of paper etc.
Spending all evening in the smelly darkroom just to get a couple of really decent prints, hand spotting out the dust specks..those were the days!!

Without getting too photographic here one of my favourite films for B&W aircraft pictorial shots was Kodak Infra-Red. Given the right day sun and blue skys, startling images could be had, sky reproduced black, foliage white…Happy days!
