“6A/780 – Indicator, Engine Speed, Electrical Generator, Mk.4”
It’s the device that, driven by the engine, generates the signal that drives an electrical engine RPM indicator.
The wrinked skin would not flatten, as being aircraft spec., it was brittle and springy.
Ian, as you say aircraft spec. aluminium alloy is brittle and springy and so will crack if bent ‘as is’. In order to work it you will need to anneal it first. That will return it to a soft and malleable state.
You’ll need a gas torch or similar but you must be very careful as the melting point is quite low and there is a danger of melting it if you get a bit handy with the flame! You should hold the torch a little way off the surface of the metal and ensure that you heat the piece as evenly as possible to avoid it distorting further. One the alloy has reached the correct temperature let it cool slowly. It will then be annealed and easy to bend and work.
A top tip is to rub soap onto the surface of the alloy before heating it. When the soap turns black the alloy is at the correct temperature. Remove the heat and let it cool. Be aware though that some alloys annealing temperature varies so the soap thing is not always perfect. It’s generally a good guide though.
It will ‘work harden’ however as you are bending, bashing etc. so you may need to periodically re-anneal it. Once you’ve finished the alloy will re-harden itself over time.
Edit: Ah! I see that Gowans fellow nipped in with sound advice while I was typing my reply!
Talk of the value of these aeroplanes while in service is irrelevant. The issue of their MoD disposal cost however IS relevant, to a degree, because it does have a bearing on their subsequent ‘worth’. When operational they were performing the duty they were designed and originally purchased for. That service is now complete, so as far as the MoD is concerned they are nothing more than scrap. They now have a new ‘life’ as potential museum exhibits and therefore a new worth on which their ‘service’ value has no bearing.
Similarly comparing these airframes to a “live Hunter or JP” is pointless because they are not “live” Jaguars. The only valid comparison is to consider one alongside a similar static Hunter or JP – take the two Hunters that were recently sold via eBay for starters. They went for around £3,500. Now’s here the big BUT – there are most certainly not 31 Hunters sitting around on a disused airfield (with more on the way) awaiting buyers. In fact there are none. So there’s a bit of a ‘supply’ difference there which will influence what people are willing to pay. At the moment it may well be a buyers market where Jags are concerned.
Yes, everyone did have a chance to bid on these airframes and that in itself means that they have taken the first step in arriving at their ‘new’ market value.
So, is £6k about right? No, for these particular airframes I don’t think it is. In fact I think ‘about right’ would be half that.
So, will this aircraft sell? I wouldn’t be surprised. The advantage, for the seller, of selling via eBay is that the audience includes people who know no different. Remember Mr Ollerenshaw and his Vulcan?
…but £6K start off price is a bit ridiculous especially when once you have bought it, you have to restore the cockpit. Lets see now, Bang seat, panels, intruments…
Ridiculous yes. Especially when you know that, in many cases, these airframes are sold with the interiors largely complete and the dealers then strip them so they can sell the parts separately to you.
were they made of steel?
No.
They were made from a resin-bonded paper material. The modern generic term for it is SRBP – Synthetic Resin Bonded Paper.
Can you tell me anything more about the people behind this pilots-notes website ?
Who are they ? Where are they ? How long have they been around ? What credentials they have ? etc. etc…. :confused:
Please !!
I don’t know anything about them but I’m not especially impressed with the way they’ve scanned the pages with photographs.
Looking through their site all the scanned photos exhibit bad Moire patterns because they haven’t been de-screened while scanning. That means that the photos have a horrible criss-cross interference pattern on them which ruins the photo – see here for an example.
Shame really, I would have bought something from them otherwise.
Thanks chaps, Sea Prince it is then.
I must admit I feel a bit guilty about dismantling this, but what it cost me to buy as a complete unit wouldn’t even have paid for half of the parts if I’d bought them separately.
FLY.BUY – will be in touch.
Dave T – sorry Dave, they were part of the reason I bought it!
I understand that one hangar has a few bullet holes made by a 20mm gun. Apparently the damage is from the inside. My theory is that 20mm rounds were accidentally fired from a Venom NF of either No.33 or No.219 Squadron while being serviced in a hangar. Is this plausible?
Well Driffield was home to the Fighter Weapons School, so maybe some of the students were a little too keen to try out their Fighter Weapons! 😀
“Apparently as he flew back toward Britain he saw a train and, as he was convinced it was carrying ammunition, he decided to fly low and machine gun it.”
My understanding was that on his last sortie Gibson was acting as Master Bomber flying a Mosquito B.XX. If so, then what exactly did he use to “machine gun” this train then? Did he take along his own personal Lewis gun which he poked out of the DV window perhaps? 😀
It’s been posted before, but here is a link to a poor quality image of the George Aird Lightning ejection photo.
http://w1.rob.com/pix/oops/7392_GHe was also the pilot of the Comet at Cosford when it was used by de Havilland Propellers, and made its last flight into RAF Shawbury in 1968 I think it was.
A classic photo, but have you read some of the idiotic comments below the picture on that website, especially towards the bottom? Good grief!:rolleyes:
And what’s with that shot anyway… did they really pull the tail down to the deck in order to generate enough angle-of-attack lift to launch?
Yup. Big heavy aircraft on small carriers with relatively low powered catapaults etc….
Did the same with the Buccaneers too.
Not sure I would have put it quite as strongly as Flipflopman, but I saw this stuff at Shoreham and it doesn’t do a thing for me either if I’m honest.
I would certainly be a bit upset if a 50 quid part I desperately needed for a restoration project only turned up stuck in the middle of a £1000 table!
If anyone has any hard facts about this could they please contact me, the aircraft does not belong to the Intrepid Museum and they have no right to dispose of it.
Whether they are “hard facts” or not I don’t know, but this is what Octobers Aircraft Illustrated has to say,
“Former Royal Navy Scimitar F.1 XD220 is perhaps the one aircraft that doesn’t fit into the museums collection. This is one of only three complete Scimitar survivors, and the restoration staff feel that it needs a good home somewhere indoors. The aircraft was gifted to the US Government by the Royal Navy, which means that the US Navy has custody of it. This apparently makes transfer of the airframe to another party somewhat difficult.”
I say transfer it back to the UK where it belongs. I’m afraid the logic of the thought process that saw this rare aeroplane swapped for a Phantom and shipped to New York defeats me to this day. What the hell were they thinking?
Mark,
Are you sure about that ?
I’m sure that’s what the bloke said, but less sure about his motives.
As a seller myself, the eBay system prevents withdrawing an item if it has bids and less than 12hours to run (used to be 24hrs).
Indeed. I do wonder if he never actually tried to end the auction early or was merely using it as a device to try to get people to bid early.
Incidentally, is it possible to cancel bids within the last 12 hours? Not sure, never had to do it on any of my auctions, but if so could you remove all bids and then end the auction early???
[edit – looks like Trumper answered my question before I’d even asked it!]
Blimey, eBay and Douglas Bader don’t ‘arf get this forum going don’t they?!!!
There is a guy who buys from me occasionally, who will buy something, and then put it on his website for up to ten times what he bought it for.
Hmm, I suspect I know exactly who you mean Bruce, and “ten times” is sometimes a conservative estimate! The true indicator of course is the length of time those items subsequently stay for sale on his website – some are there for months, years even. Says it all.
I really don’t ‘get’ the grumbles about last-second bids on eBay. There used to be a regular seller who ended his auctions at some random time in the last 5 minutes. He said “I hope this returns the auction process to the person that bids the most money rather than the one with the best sniper program”. In my opinion the bloke was a complete fool who had no understanding of the way eBay works. Complain all you like about snipers, the simple fact remains that whoever bids the most will ALWAYS win the auction no matter whether they bid 2 seconds after it starts or 2 seconds before it ends.
I always bid very late. The technique has served me well and I will never apologise for it. The only times I’ve felt any guilt is the odd time when I’ve used an unattended sniper program, because I’ve been away at auction end, and found that I’ve outbid a friend! That sometimes takes some explaining!
I really don’t see the fact that the winning bidder in this story bid 20 seconds before the end has any bearing on the issue. If the seller sold the aeroplane by other means, then why on earth let the auction run its course and produce a ‘winner’?
