No problem, built by two metric countries. It all falls apart when you try to work out how fast it's going or how far it has gone. 😏 Mike I thought the UK was still Imperial when it was first conceived ??

A picture of Concorde featured on the front cover of Model Engineer is the 1950's - so we were probably still Imperial then.
I still am!

Afternoon everybody.
Just to add my four penn'orth ref Concorde and dimensions.
I worked for Bristol Siddeley/Rolls Royce Aero Engines on Olympus 593 engines (for Concorde) from 1966 to 1970. I was there for the maiden flight of 002, the Bristol built prototype. ( My avatar gives a clue).
IIRC all dimensions were in imperial decimals. Folklore has it that SNECMA in France, who built the afterburners, worked to metric dimensions. When engine was mated to afterburner, for the first time, they fitted perfectly.
There was only one computer on site, the size of a bus, and everything was on punch cards. We all still used slide rules.
Happy days
Cheers
Malcolm

Hi Nobby--------package in the post for you tomorrow........One of the lads at ABRO Donnington was an Ex-RAF fitter on Hunters and he would fondly remember the blisters on either side just below the cockpit as "Sabrina's"...after a well known film star of the day............Can't think why LoL !! I have a friend currently living in France who was a Hunter Pilot back in the Aden situation days...........Apparently cashiered out of the Service after flying his Hunter UNDER tower bridge !! ( Urban legend probably but knowing John there's a 90% chance of it being true !!)...

To-day the final part to adapt my Chester Craftsman lathe to 5C collet capability arrived from the USA and it fitted perfectly straight away----naturally !! 5" gauge loco axles at 0.750" diameter concentric and accurate quickly by the score now !!.............amongst other things.

Far from it - actually happened on 5th April 1968 as a protest at the lack of events to mark the 50th anniversary of the RAF. Is his name Alan Pollock? Regards, Dan

Tonight I made myself a small brass faced hammer for use while dialling in components held in the chuck whilst using the DTI. I'm very happy with the knurl bearing in mind I've not had much experience of it. Everything is threaded together. One face is the bare steel at the moment but I may yet put either a sacrificial steel head on it or a nylon face. We shall see. I'm very pleased with it regardless. The handle is just the right length for popping Morse Tapers from the tailstock. Re: the package, thank you Alan, very kind indeed.

S11, waiting time at the Gympie Platform , about to have my 6th trip down the Mary Valley Branch on the right hand side. We coaled before we put the carriages away, the chap who loaded the coal made a picturesque pile (8 + ton), I thought it was a Kodak moment.

Is the coal processed to be an optimum size or is it as delivered from the coal yard?

I watched the maiden flight of 002 from Bedminster Down. A fabulous sight.
On a slightly different topic, as the relationship between imperial (inch) and metric (mm) is well established, it shouldn't really matter what units you use. It doesn't matter whether a piece of material is 25.4mm or 1 inch - they are the same size. The only issue may be the tolerances, and if these are stated, all should be well.
(Sorry - been away and only just catching up).

You may well have seen this already but it's well worth a quick look.
Amazing what we were able to do back then, eh?

Have just been trawling you-tube and found this colour footage in 1940's Paris...It was taken by a German cameraman and has some interesting views inside a makeshift Lufwaffe repair hanger amonst other things........Remember this is actual, real-time film and not a Hollywood sanitised version.....Made me feel quite uncomfortable --- as if I were one of the French civilians for a moment............

Is the coal processed to be an optimum size or is it as delivered from the coal yard? Brian The coal is from Gunnedah in NSW. It comes mostly as you see. I have no idea if it is processed at all but I know that it is hot stuff! It can be dusty but some recent rain has helped wash the pile down. It is very smokey till it goes and when it goes it is hottttttt and the smoke clears. We just received another couple of loads and the sizing is just lovely. The odd big lumps which I keep for under the door leading up to a decent climb. Low ash and no clinker seen yet. I am told it is the same coal they use for the AD60 Garratt. We have only recently switched from the Qld Blair Atholl coal which was of mixed quality, it was OK, but this Gunnedah brew is happy times firing and cheaper per ton. It is a bit slower to get going but when it does get going it hangs in there. One has to be thoughtful of not having too much on with long coasting sections or platform dwelling that are coming up or she will be howling off. You can leave a good bed of coals with no flame and it gives off good heat for a decent time, down hill and standing at the platform. 10 mins to go, go around the box, a touch of light blower and the bed is fully alight. I reckon we use 10% less as well.

See what you think}--------- youtu.be/xOMg75L8FI4I seem to recall the Champs Elysee being used as a runway. It was to celebrate 100 years of aviation. My late wife was collecting another degree, this time an Open university one. As for the flying under Tower Bridge, I recall that it was once quite popular. I recall the AOC in C, Coastal Command's Devon C1 VP-981 flying too low over both it and Buckingham Palace in February 1950. HMS Truculent had sunk off Sheerness, ironically just after the film Morning Departure was released in the Provinces. '981' had been in RAF Hendon's Workshop's and I caught up with it on Hendon's peri-track for a joy ride! The safety equipment was a bass fiddle parked along one side. I suppose that if we'd had to ditch, that was it. The driver played bass in the Station Dance Band called the Hendonaires and the late Keith Christie was jazz trombonist and one of my 'erks' '981' became the 'hack' for the Battle of Britain Memorial Flight and to correct the 100 years of the RAF thing, we , as 31'ers celebrated TWO years early- as we were RFC. Who said National Service was boring? Norm
