    despite what all the doom mongers say, there is nothing wrong with using WD40 at all. PX24 is not readily available from retailers, neither is ACF50. WDis fine for what you are doing if you are prepared to re-apply it every 3 weeks. If you can mix it with 40% heated Wax oil and apply, even better. New engine oil is particularly good, though attracts some dust after a few days, and expensive. I can think of two very nice Lightnings that have survived 25 years of open storage with 60/40 WD40/waxoil, and has done them zero harm! If Wd40 is what you can readily get my friend, then mix it with clear Wax oil and go for it! if you can get PX24 then great.

    We were rather surprised at how well No 3 ran given the wear. We had it up to about 1,850rpm,

    1850? bah, come on boys, give those griffons some damn stick:rolleyes:, get em up to 2200-2500, get some boost going, and save yourself all that plug cleaning!!;)

    to be honest, you have the ap’s and you can’t really get the prop hanging wrong anyway unless you are a complete donut, which you guys clearly are not, so I wouldn’t worry 🙂

    Noble sentiment chaps, but seriously, it aint going to happen!!.

    I can tell you first hand after taking two apart and putting them back together again for running and flying respectively, it is a mamoth undertaking!!. taking apart properly is one mountain, getting it back together to run again is an entirely different mountain. 724 in pieces, then up to Elvington, would take 3-4 years to put back together with team members from Brunty, Binbrook, Cranfield, GAM, AALO every single weekend, to a safe fast taxying standard. I’m afraid none of these groups now have the slack or time to take such a feat on. Once you have disturbed the wing centre section, you are in for a world of frustration and pain when you put it back together again. sometimes the RAF couldn’t get it right, and they flew with minor centre section leaks ,inspected every few flights. That is not acceptable, but operationals needs dictated. You cannot afford to do that as a privateer, so it has to be exactly right. They are NOT meant to be split in half!!, thats why its so dofficult. With a full vacuum kit and all of the right skills and materials, you can get the centre section dry again. It took us 2 years alone to get that right, in and out of the tanks, struggling like **** using every single method by the book, with all the right kit and 20hrs a week hard graft, and shed loads of knowledge. Trust me, she is better off where she is in one piece, and a team put together to bring it back to standard. The idea of moving her to Elvington from Binbrook is simply nuts. If it were somewhere with hangarage, power, water, tools etc, then it would be a far flung idea, but entertainable. The other thing to remember is they do not want it else where, she is to stay at Binbrook for thew proposed museum.

    XM365 is almost ready the uc system was retracted at the weekend (to aid fitting of the doors) and is complete other than rigging of microswitches however we run with ground locks fitted so it’s not a priority, the fuel system is 90% complete the last of the collector tank pipes need fitting. The hydraulics are complete and the uc retraction revealed a few pipes that needed tweaking up

    all that remains is to hydraulically connect the foot pedals, install another set and bleed the brake master cylinder and foot pedals, and “simply” charge all the uc legs apparently you can cx the jp standard charging point for a standard schraeder valve type which would make thing a lot easier

    It can then come off jacks and go for ground runs and leak testing after which the seats can go back in and it can all be panelled up, with a fair wind and enough willing hands it’ll be ready for this years open days

    and then we can tweak the vixen !!!!!

    oh and the small matter of a gnat and hunter

    kin ell! how do you few blokes get em running so quickly!?! you’re knocking em out on a conveyor belt

    no one tends to waste avgas any more peter. if it’s defuelled, its normally put back into the same aircraft, since its so expensive. we had thought of using super unleaded with lead additive, but it works out just as expensive by the time you have got it up to the minimum RON

    Rich, your more than welcome anytime at all. yes it is a problem having all the airframes to fettle, never anywhere near enough hands!

    Rich, hats off to you and the guys for doing the best you can. We know down here first hand what a losing uphill battle an old aiframe like the shack is. For all those that enjoy images and sounds of a running shack in the UK, savour it whilst it lasts, because at 800quid per ten minute run, i’d be surprised if these last two runners are still running in 3-4 years time, it just isn’t sustainable, and donations get smaller and smaller every year, with folk feeling the pinch. The Astronomical costs of keeping them running, leaves almost zero funding to do much else with them. “Juliet” hasn’t run for quite some time now simply becasue of the fuel costs being so high, it’s been a lean year.

    The cost of paint and materials alone runs into thousands. Avgas is pushing 1.90 a litre, and you need a minimum of 80-100 gallons to do a run long enough to get everything to operating temperature on each engine.(80-100 for all 4 I mean, not each engine) Do the basic maths, and you can see why runs are seldom these days. Just peoples basic petrol costs to travel up and down working on these airframes is now a consideration. We have lost a few volunteers in the last 6 months purely because it costs then £35 in fuel every time they come over. In an ideal world we would love to pay their fuel, but evryone is in the position. Its not all gloom and doom, but something as large as the shack running, well their days are very numbered.

    Rich if you ever need any help from us in the way of advice don’t hesitate to drop me a PM. I can certainly provide you info on hanging the props as we have done it several times, it’s just too far for us to come up unfortunately, and we can’t afford to lose a crew member for a day as it is.

    no brainer, cams out! unless those pics are an optical illusion, I fail to see how they are “within limits” or how polish and regrind will fix those lobes. the lobes have gone, not to mention ramp and duration will be a mile out. I’m surprised those cylinders even fire.

    heres what we do on ours for instant starts and clean plugs!

    do youself a favour to save labouring the starters, props and spinners. since you haven’t run her for a long time. Do your prep in the morning and run her pm. check your lp filter bowls first, they will have water in them after this length of time.

    1) in the morning, crack all of the bank fuel priming lines at the firewall and run the priming pumps, bleed the lines through to there, reconnect. 2) open all four lp cocks in the morning, push all 4 throttles fully open, and leave it that way for about an hour, then run the boost pumps briefly whilst mags off turn each engine through 3-4 revolutions until fuel issues from the bottom cowling drain.

    if you do this, she will start within 1 blade turn on every engine in the afternoon. it saves a shed load of wear and stress on the starters, airframe, props, translation unit, fuses etc. that’s the secret to griffon starting on the Shack, if they run infrequently, more importantly is stops you fowling the plugs during start, and saves you having to clean them that often. once shes running clean, run em all up to 26-2700 in pairs before shut down and your plugs will be as clean as a whistle on shut down

    as for your cam issues, suck it and see. if that engine runs like a dog still, then you know your going to have to do a cam swap.

    ah ok, i c. Well I wouldn’t go so far as saying Juliet was taxied, she was moved under 2 engine power to a new parking spot some years ago, but it was only about 20ft or so. it was just less hassle than having to borrow a Shack tow bar!

    Hi Wyvern,

    depends what you mean by status on XN923. She wont be taxying any time soon at GAM, the runway is grass, and 923 weighs in at around 14 tons. She is currently a runner, but the port engine requires changing asap, as it’s on its last legs. We have a replacement low hour gyron, its just a question of getting time to do the change. She will next run in January. If you fancy volunteering, 923 is always in need of extra hands, as the current team of 6 are a tad stretched with 4 jets, a shack and a Sea prince!

    Very sad indeed.Whilst I understand why it is being chopped, it seems short sighted to retire it simply because of its high operating costs. I would have thaught the Gr9’s offer more bang for the Buc, and more versatility in the long run, when compared to the tonkas left behind ? lets hope a good number of them come up for disposal in one piece, and a dozen can be flown into preservation and kept live. I fear that won’t happen though, since all the engines will surely go back to Rolls for redeployment.
