    The hydraulic hand pump appears to be a standard American AN6201-1, used on lots of aeroplanes (or should that be airplanes in Yank speak?:diablo:). I have used them on the P-51 to run the hydraulic system, where it is attached temporarily via a bracket onto the right hand engine mount and plumbed in via quick disconnects on the firewall.:)

    Not professing to be a Merlin expert, but a damaged aneroid in the Boost Control may prevent full opening of the carburettor throttle valves, therefore reducing engine power output. The boost control is used on some supercharged engines (mainly high powered) to limit the maximum boost pressure produced as the altitude varies. At low altitudes, without the automatic boost control, it is possible to overboost the engine by opening the throttle valves too wide, running the risk of damaging the engine. The Reno Race engines have the boost controls bypassed or disconnected to allow boost pressures of up to 140″ Hg.

    Alec Wilson has collected quite a bit of Spitfire stuff, but I believe his project(s) are very much on the back burner these days.

    4130 is not ideal either, because it has a tendency to crack with the sharp radius bends so prevelant in the Sopwith fittings. Bob’s flat pack should end up looking something like this boys and girls….:)

    QldSpitty, these fittings should be 1020 mild steel and after a bit of a clean up with a file, should be good to go. I wouldn’t laser cut Al Alloy though, for your stated reason; a water jet cutter would be the weapon of choice. 🙂

    I think I paid about 120 pounds for my copy, but then it didn’t need to posted quite so far either…:)
    I have known Keith Megs for about 30 years and he has been toiling away at this project for as long as I have known him, so I was rather keen to obtain a copy. Well worth the wait.

    You would be right wilkofife!:D
    That’s my cunning plan uncovered then…:o
    The Sylvander Biplane is featured on pages 109 to 111 and the picture was on page II-79 of Keith Meggs’ Australian Built Aircraft and the Industry. Volume One: 1884 to 1939, Book 1. ISBN978-1-920892-77-7. Very expensive, but I consider it an essential addition to the library of anyone interested in Australian aviation history. I believe that Keith has been researching this book and its soon to be released Volume Two for over forty years. 🙂

    My apologies for the delay fellas, but I guess it is time to put you out of your misery.:D
    This Wot is known as the “Sylvander Biplane”, designed and built by Victor Sylvander, a Russian Finn in Hay, New South Wales. Having previously designing and built a few successful gliders, Victor designed a powered biplane using knowledge gained from Flight magazine, hence it was inspired by the BE2, rather than licensed built. Construction started in December 1913 in the Hay Cobb and Co stables and a 90hp Renault V8 was bought for the aeroplane, but this was seized by the Defence Department in Melbourne after arrival from France due to the First World War starting. A 40hp ENV, a liquid cooled, horizontally opposed, four cylinder engine was procured from John Duigan instead, to power the biplane and it first flew in April 1915. It flew several times, but was found to be very underpowered. The author of the book I found this wot in says he saw the remains of this aeroplane in 1964. I do not know if it survived beyond that.
    I think I will reveal the title and author of the book after I have sprung a few more good wots on you all… 🙂
    I’m off for some shut eye now….

    Dragon Rapide G-AIYR / HG691 has recovered from her recent damage and was engine running today:

    Man, that was quick!
    As someguy1 said, it’s good to see the Rapide back in one piece. It would be nice to know what was involved in the repairs.

    ‘Fraid not Skyraider3D. This wot was not licensed built but was a close facsimile of the BE2. I’ll let you guys sweat for a bit longer, mainly because I have left all the details at home.:o
