    And you are perfectly entitled to your opinion.

    After all maintaining one of the finest aircraft museums in the world probably only costs about two pound fifty a year. All the rest of the income goes into the pockets of Duxford’s management I expect. :rolleyes:

    Aah, but there’s “Rip off Britain” version of accounting and common sense.
    They charge such a price because they are recovering the costs based on the attendance that is on record. They (And a great deal of UK businesses) dare not take the risk of winning! If they charged half that price they may get three times the amount of visitors, which actually pulls in more money.

    Same as pubs, prices get too high, people don’t go to the pub….brewery increases prices to maintain their margin and greed. Self realising destruction.

    Absolutely superb, as usual.

    What was the reason to put the Griffon in that Spit? Is it / was it the only one done?

    A friend found a Bronze ring under a bush whilst on Holiday. It had developed a slight patina so had been there for some time, It has a strange script(to me!) that appears engraved all around it, both inside and outside I have reproduced as best as I can manage it. this line of script is repeated to make an almost continuous engraving.
    Any ideas from the many learned and varied posters here?

    Are you sure it is Bronze and not Rose Gold?
    Bronze would be an odd material to use unless it’s a home-made ring.
    Or a cheapskate plumber using an olive from an old fitting 🙂
    The lettering looks Mid-Eastern and I was going to say that all-round engraving is usually associated with Wedding Rings……..but I’m not sure if the mid-east actually have wedding rings?

    I got an e-mail today from ‘Symantec Store’ telling me that my subscription had expired…

    …it hasn’t, I have over seven months left. I didn’t open the e-mail assuming it was malicious.

    Also got something at the same time from ‘News Update Service’, deleted that one too.

    Let’s be careful out there!

    It’s SPAM, so is the news thing. Delete them without opening. If you have opened them, all you do is tell the SpamBots that your addy is live and you will get a deluge. Opening in preview pane is actually opening the file so don’t do it.

    It’s about time crass, wilful, stupidity became a criminal offence in it’s own right.

    Preferably punishable by marooning on Rockall or, better yet, Gruinard. 😡

    Well, I agree. There would be a long line at the Courts if stupidity was the offence though!
    As a nation that is infested with trash TV (All soaps, big brother etc.) the youth seem to be getting thicker and thicker. Their ability to remain pointlessly dim is enforced by equally uneducated and generally inept role models. And then, to enable a balance, the standards are widened/softened/ruined to allow underachievers to “Achieve”. Most of them have delusions of mediocrity.

    It’s well into the 3rd generation of chav/pikey thicko’s now, too late to repair.

    Gruinard…..is that yet another way of spelling “Guardian” (Of newspaper bad spelling fame!!)

    It belongs to AeroSur of Bolivia.

    Its the first big aircraft in the fleet, and they are due to start using it to Madrid. Its been painted up in a special livery – it has a giant Bull on the nose and the aircraft has been named “Torisimo”

    LoL. You can only equal the low flying record!

    Note how he starts to bank to port and then checks it….he must have remembered he was 60 feet up and this thing has long wings! Then he climbed a bit then threw it over.

    A torpedo is definitely the way to go for a sure kill. Missiles are not a sure thing depending on where the strike hits. A target ship, the Ashtabula, a retired oiler, shows how hard it is to sink a ship. Granted, it had all fuel removed and therfore wouldn’t burn or explode.

    ” In all, the oiler was subjected to eight Harpoon missiles, two Standard (SM-2) missiles, three Sea Skua missiles, four bombs from S-3 Vikings, and over 100 rounds of gunfire from 3″, 100mm, and 5″ guns. The ship was then sunk by demolition charges as it refused to sink!!”

    The original clip at the head of post isn’t very good at showing the damage and other stuff we like to see. It was edited by the BBC to fit in a “Drop the dead donkey” slot at the end of the news when nothing else is going on. There are some decent Torp tests on You tube or LiveLeak, search for Type 48 Torpedo and your dreams will be answered.

    Open RAW file in CS3.

    Adjust white balance (if I need to, which I ususally don’t)

    Crop (or tell the program where I want it to crop)

    Adjust exposure/blacks according to what the histogram tells me

    +16 saturation

    +60 sharpening

    Convert to JPEG

    Heal out dust spots

    Re-size to 1024 wide

    Apply USM at 30%, a radius of 0.3, threshold 0.

    Upload to JP…

    There may also be some subtle dodging, burning and selective sharpening if needs be.

    Paul

    Rather than hit the sharpening at 60, better off doing it 6 times at 10 (Or rather 5 times at 10 to get the same force). The difference is visible and better. Likewise USM, 3 x 10 is better than 30. I use High Pass filter at about 70% opacity then an USM – 2 at 5.

    Appearently not to a great extent.
    I’d guess (since I’m not an engineer) that at GA speeds, a wink is as good as a nod.

    In his excellent book, Cessna Wings for the World — The Single-Engine Developmernt story*, long time Cessna engineer and test pilot, William D. Thompson says when the straight tails were changed to swept units in the early 60s, (purely for marketing reasons) the rudder became less effective which showed itself in reduced crosswind drift correction capability, spin recovery authority, and an overall slight loss of directional stability. It also increased weight and cost.

    *1991 Maverick Publishing.
    It was followed by a book on Cessna light twins (336/337, 310, 340, 303, and T-37), and then a third book was released dealing with the heavier 400 series of cabin-lass twins.
    All three books should be on the shelf of anyone interested in the develoipmenbt of GA aircraft.
    It’s a pity more hasn’t been written on the subjecty, there are a lot of good “inside stories” still to be told.

    It would have increased weight and cost at the time of change, basically when jest came of age, but we’ve overcome those problems now. There would probably be more flutter on a fin with an upright leading edge. The shorter the body length to diameter, the bigger the fin. Lok at A380, that outrageous fin on a dumpy body. If the Body was twice as long the fin would get smaller (If it’s further back from the turning moment it has to do less work).
    Single engine prop jobs have a non uniform fin. i.e. in cross section the shape more resembles a wing, with one side nearly flat and one side curved. This counters the shear from the prop. In twins and upwards, the shape is the same at either side of the chord.

    Isn’t there an a/c with the fin facing forward? Looks like it’s on backwards?

    from an ameteurish POV, there would also be structural problems in that configuration. due to stress i.e

    Good call.
    The fin mounts on any A/c are beefy as possible. The fin takes a hell of a side load when the rudders are rammed over, even more so in a fighter where unfeasible manouvres are done frequently. The wonky configuration as per sketch would need an off set Spine, the spine would need to start off central at the back of the driver, then bend over towards the top of the Stbd lump.
    This is of course possible to make, possible to design. But it would be a nightmare to mass produce, and possibly worse to fit. On Single jets, the engine mount ring usually has a small spar coming off it, and the whole ring is angled backwards at the approx. angle of the vert fin. The components are often known as Banjo’s. To have the spar attaching to the side introduces all sorts of odd loads…..again these are possible to overcome but at the expense of weight and cost to build. Also, adding weight at the blunt end may throw the whole CofG into disaray, so an equal weight may be needed at the sharp end……..or, leave it all to fly-by-wire I suppose.

    I trust you are downloading the RAW images direct from your camera to your external drive via the PC and not doing any processing on the camera/card 😮 first.

    Absolutely no not ever.

    USB drives are laboriously slow. Is the Maxtor 500 IDE (PATA) or SATA? If SATA I would invest about £20 into a dual USB2/eSATA enclosure [click], then you’ll have the best of both worlds. If PATA I would mount it internally for the best copying speed, if at all possible

    If your PC doesn’t have an eSATA socket, you can get PCI cards that will provide the functionality – probably from the same place.

    That should increase speed somewhat – but you can also get eSATA card readers, and they should give an improved copy speed too.

    Of course all that’s a load of b*ll*cks if it’s a laptop, very few have eSATA, and none can take a 3.5″ drive internally!
    Not laptop, a real computer!

    Forget about printing dimensions – when copying from your camera you want to copy the entire file, thus image print size isn’t relevant at this stage.
    Yep, as per my answer above.

    Always keep the original file copied direct from the camera (work on a copy) – you might want to go back and have another go at getting the image “just so” as your image manipulation techniques improved.
    Yes, that’s always been the case since I went digi many years ago. It’s only recently I’ve gone to RAW – I used high qual. Jpegs and printed to A3 (Often cropped too) with a quality that was winning me competitions. But alas I’ve decided to go RAW and play more with the extra quality 🙂
