Diary December 2016

I managed a little more controversy last time from hopeless dog owners and that’s always a laugh but I’d not reckoned on just how many people believe that keeping foxes alive is a good idea! Not so many share that sentiment about rats yet rats are landed gentry by comparison.

I have a happy little family of them at the bottom of the garden. They’ve dug themselves an underworld through the compost heap behind the turkey shed and there they play happy families, stealing food from the chickens and turkeys and gambolling playfully under the fruit trees. I have great affection for them just so long as they stay at their end of the garden, which they mostly do, though I keep their population under control with rifle and trap. They’re clean, country-living rats. Playful little things and infinitely cunning whilst doing no harm, yet if one scoots across the patio while there are any visiting women looking out of the window the shrieks can be heard from miles away. Let’s be honest here. In general, and I always say that exceptions do not disprove rules, a bloke will say, ooh, a big rat just ran across your patio while a woman will scream the place down and leap onto a chair. It’s just the way of the world.

But should a fox stroll into view it’s all, ‘Aww, how cute!’

Yes, foxes look pretty, but they really are the Devil’s instrument. Neither dog nor cat the fox embodies what’s worst in both whilst flouting the animal kingdom law of killing only what it needs to eat in favour of mass murder. Dog foxes will get amongst your flock and kill the lot, but at least have the decency to then bury them and return to feed on them later so you can shoot it when it does. But vixens just kill everything in sight, lop off their heads and leave the place looking like a suicide-bombing hen just exploded amongst them – then someone else shoots it, usually the local gamekeeper who says he’s done for about 350 of them this year without making the slightest dent in their population. As may be imagined – townies lack what’s needed to understand this… until Tiddles the cat is reduced to only his head on the lawn one morning or your twins are mauled in their beds.

That sorted the hateful creatures out – the pest controllers in London didn’t know which way to spend their money for months after that. Face reality, townies – foxes are bad to the core and best served stone dead.

Then we have dairy herds built over many years by dedicated farmers being slaughtered because badgers are infecting them with TB, (which humans don’t really want to catch) when the obvious thing to do would be to slaughter the useless badgers instead. They’re no more endangered than foxes but, no, let’s have bTB in the milk and a big hoo-ha about popping a few of them with a rifle. Look at it another way – it would drive down the cost of shaving brushes and sporrans.

The problem seems to be that the ‘save the ant’ brigade so totally believe the nonsense they’re fed that they’ve become too blind to look beyond it.

I can’t deny that it’s often a necessary tool to garner the resources needed to do any real good. When I used to dive for Greenpeace they would blatantly promote the myth that rainforests are the lungs of the world and dolphins get caught in mid-water trawl nets but it kept the cash rolling in for the stuff that does matter and that’s a difficult stance to argue with.

I was stopped in the street lately by a pretty girl bent on saving the planet by having me adopt a Snow Leopard. Telling her that it would make a splendid hat did nothing to dampen her fervour so she rattled on about the horror of fox hunting without ever questioning gassing vixens with their cubs in their den to rid the world more efficiently of an entire generation so what right did she have to whinge about giving one a sporting chance by simply outrunning a few dogs? No one I ever met who lives on or works the land ever spouted such nonsense and this dizzy, indoctrinated, do-gooder certainly didn’t tick those boxes but you’d imagine that instead she’d have enough Internet, intelligence and technology to have dug into the people she was representing and discover that it was actually an advertising agency, not a charity, that talked well-meaning folk into parting with three quid a month in exchange for some glossy pic’s and a tuppence-ha’penny cuddly toy.

Yes, they had the WWF panda logo all over their blurb but get into the small print and it turned out that it was a company owned entirely by its directors that made a tidy profit, offset the goodwill against its tax and made a ‘small’ contribution to the WWF in exchange for being able to use their logo to sucker in folk who absolutely must have a Snow Leopard.

Even the WWF – honourable charity that it is - has a couple of trading companies tucked away at the back of its effort with a healthy investment portfolio and tens of millions swilling about. Go have a dig around the Companies House website and find out for yourself that their bill for temporary staff last year was £200k and how many people are on £60k or more. Not saying they don’t do good things around the world, because they do and are worthy of respect, but precious little of your three quid ever makes it to Snow Leopard country.

On the plus side, though, for everyone with no fox experience who think the damnable things should live there were ten more who got in touch to say how they’ve ridden with the local hunt since they were nine and fully support the gamekeeper so the world hasn’t quite divested itself of all its common sense – yet.

But the one thing I detest more than ill-researched do-gooders is so-called technology that takes mankind backwards rather than forwards. Remember the car for tetraplegic morons? (Oh, by the way, I also had someone mistakenly think I was disrespecting disabled persons rather than the car. I do hope he’s not tetraplegic, that would be a double hit) Well I saw it outdone last week.

My car is due to be replaced and the model run out and supplanted next year with its prettier, younger sister so the way I see it is I’d rather have a MILF-like, reduced-price, properly sorted machine with all the toys and a final hurrah to a car I’ve liked and lived with for a few years rather than an over-priced and somewhat underdeveloped virgin years off its full potential. Of course, if you want to impress the neighbours, give a hoot what anyone thinks or can’t live without the cloud in your electronic gearbox syncing with your central heating at home you’d best rack up some debt against the latest expression of your vanity, wealth and perceived success; but if you want to save a fortune and exercise your common sense then best go for the run-out model. So this is what I was about to do until it doomed itself to death.

Now I have very strict rules about what a car should be. Firstly, it shouldn’t be any bigger than it needs to be so all those ocean liner sized, pretendy 4x4 things with massive wheels on low profile tyres are out straight away. Why would you buy fuel to haul twice as much machinery as you need around the place? Those things are just the engineering embodiment of fat people’s diabetes.

That said, those biscuit-tin sized horrors that transport your fragile feet three inches behind the plastic front bumper and promise to emit no carbon dioxides from their three cylinder, half- litre engines yet, on paper, will save you with airbags if a Range Rover whacks you at 80mph should be outlawed at once!

Nor do cars need more than two doors unless for medical reasons.

OK, old, infirm or disabled persons may struggle and need a larger car with easier access but not able-bodied grownups and certainly not those with kids. My two will happily crash into the back of a two-door coupé complete with school bags, books and coats faster than they could escape a burning building, and that is exactly what they do of a morning and why the end of line, properly worked out car I tried proved a total disaster.

We’ve all had a go on electrically adjustable stuff, I’m sure. And we know how slowly it travels – and with good reason. You don’t want your car seat or telly-facing armchair or conservatory skylight to whip over and take your head off. The ergonomic engineers of this world earn their salaries by knowing that every animal on the planet is programmed to be startled by things that move fast and soothed by things that move slowly because the former is likely to eat you whilst the latter probably wants sex; so electrically operated things are designed to glide with a whisper that wouldn’t trigger the alarms on the Crown Jewels.

So picture the scene… I’m strapped comfortably into the heated driving seat, the salesman is about to hop into the passenger side in case I go daft with his car while a pal of mine who is along for the ride is waiting to limber into the back. Except that having flipped the handle to slide the seat forward he finds that it won’t budge except by servo-operated nonsense that has all the urgency of a melting snowman. It was interminable! With an infuriating mechanical buzzing the seat inched forward like Dr. Nefario’s scooter in Despicable Me.

Yet this, according to the salesman, is better ‘because it’s electric’. It matters not a jot that our would-be back-seat passenger was gently soaking in drizzle with no means of attaining the shelter the car ought to have provided, or that the salesman was similarly placed twice over because he would be last to enter.

It was better because it was electric.

The rear seat was eventually graced with its damp recipient then the process reversed to let the salesman in about a fortnight later.

The dealership – true to form – then mailed me later to ask me what I thought. Or, put bluntly, to check out their chances of flogging me the thing, to which I responded with more or less the above. Two days later I was there for a completely different reason only to discover that, following my mail, the rest of the sales team had been for a look to see what I was on about and all agreed it was a ridiculous piece of mechanical crap.

They tell me, and I’m not kidding here either, that next year’s model has a feature whereby when you want to park, what you do is get your new car somewhere near, get out, and then using your telephone, tell the thing to park itself.

What kind of mind-boggling stupidity is that?

First of all, if you can’t park your ton of ironmongery you shouldn’t be allowed to take it onto the streets or anywhere else. I mean, can you imagine flying off on your holidays with a captain who’s hopeless at landings but he can have his jet do it on its own by means of an appamabob on his SheepPhone 7?


And what to do with the wife and kids as part of this process? Fetch them out into the street before telling your telephone to move the car, in which they were safely cocooned moments earlier, potentially through the space they are now occupying? Leave them in there while you attain a safe position and hope that nothing goes wrong, or do you stay inside to be digitally emasculated by a widget when, were you any sort of a man at all, you’d be able to park your own bloody car!

Mankind is using his hard-won intelligence to make himself as stupid and lazy as he can possibly become! Those fat people on floaty chairs staring at screens in the film WALL-E are a terrifying vision of the future in my opinion!

But at least the bedrock of our engineering heritage is intact and this is why our engine of yesteryear shares much with today’s machines. The fuel pumps on modern gas turbines are still full of pistons and carbon-carbon seals. They have elastomers and o-rings and gaskets and so the time finally came to stop talking a good job and get our hybrid 701/101 spun up into some kind of action.

Our main engine is an ex-Red Arrows unit that flew with Red#1, ‘Dickie’ Duckett, in 1976. It was then used for ground-running for a while before being retired when the aircraft was overhauled. We’ve had it tucked away for years. In this shot we’ve popped the oil tank up top but there’s no fuel system on it or a starter. The starter went on first.

This is a brand-spanking new Rotax CT1009 start turbine and is meant to be used with LP air from a Palouste starting cart but we had it looked at by the engineers from Goodrich Power Systems, who inherited Rotax, and it was declared safe to run on compressed air, albeit very inefficiently – we’re working on that problem. The worry was that it has thinner casings than the HP starter so it might burst but they said it wouldn’t. Next we finished repairing the old inlet bullet.

This has been around for years too but, despite being saved whilst under the water by having a coating of magnesium hydroxide somehow deposited over it from the slowly dissolving compressor of Bluebird’s crashed engine, there was still much corrosion to be tackled and its mounting flange had different hole spacings to the 101 too. It looked OK but still took many hours of careful reworking to bring it to a condition where we’d let our precious engine breathe through it. We also had to modify it inside to clear the larger diameter starter (the 701 engine uses a CT0801 and, though we have one, it’s horribly incompatible with the 101 gearbox) and then the compatible starters we do have must be partially dismantled and the inlet clocked through ninety-degrees so we can admit air through the old 701 pipes. Just getting the starter in and the inlet on was a major undertaking. Not as major as getting the fuel system on, however…

Having decided that we’d be spending long hours under there we put the engine up on stilts and commenced our head-scratching... What we discovered quite early on was that the 101 filter bowl was held on with only three bolts though four holes were provided on the underside of the compressor casing. Next we realised that, though our 701 filter had four lugs for bolts to pass through they didn’t match the ones on the compressor – at least not all of them, but we could get three of the four (not the same three as the 101 filter, though), so this meant, in theory at least, the three it had would give us a fixing at least as strong as the different three that the 101 filter employed.

Here’s the filter bowl bolted in place. The silver thing sticking out of the left side with that downward-facing plug connector is the low fuel pressure warning switch whilst on the other side is the rigid pipe taking fuel to the piston pump, which you can just see disappearing out of shot on the right. In the middle is one of the fixing bolts, noteworthy for the small, wedge-shaped shim just visible between the filter and the compressor case.

That rigid pipe (never call them ‘solid’ pipes or someone from aerospace will get annoyed and point out that if they were solid they’d be a bar and not a pipe at all) is an extensively modified 101 part to get its angles and length correct so it went off to visit Barry Hares on several occasions until it decided to play the game. There’s another rigid pipe on the other side that delivers HP fuel from the pump to the rest of the fuel system.

You can see it snaking away from the pump on the left and we got lucky this time because it’s another 101 part that fitted a treat once we’d swapped a few other bits and bobs over from the later engine – namely the elbow where it connects to the pump and the wire-wound filter at the other end where it meets the CCU. There’s a lot of other plumbing in place in this shot too. See that black hose coming from the bottom of the pump and disappearing into the fuel system? It delivers the all-important servo pressure to control the engine and schedule fuel on start-up. This pressure-term was to cause us no end of difficulty when trying to integrate the old 701 fuel system with the 101 engine but more of that presently. Just a quick reminder of what we started with. The fuel system was in recoverable condition because once the compressor case rotted all the gubbins dropped into the mud where it was preserved. There was also very little water ingress so kerosene looked after most of the internals. We got very lucky there – not least because of the incredible rebuild job done on it.

That was the hard part done and the rest of the plumbing was a fairly straightforward case of rinse and repeat until our engine would, in theory at least, get up and go if we added fuel, sparks and a good shot of compressed air.

Now then, by this time we had been very kindly invited to do our engine testing to full power at RAF Scampton as guests of none other than the Red Arrows! How cool is that?

But the snag was this… Absolutely no way were we going to be allowed to give it 100% until we could prove that our engine was a viable asset and that we could handle it outside of the boat – and quite right too. We’d therefore have to rig it to run in isolation and these engines don’t take easily to such treatment. They’re designed to be an integral part of an aircraft with controls and systems predisposed to operate in perfect harmony with it – not hacked out like someone’s liver then asked to keep on functioning on the slab without the rest of the body for support. What would we need?

How about… fuel?

Many moons earlier, from the depths of the mud-crusted hull, we’d dragged up this sorry looking colander of a thing.

It’s a small, six-gallon fuel tank with a submersible boost pump mounted in the bottom and, being made of 16swg steel, it was shot to Hell.

It’s there because on the Beryl engine fuel entered at the top so the fuel pipe from the tank is at the top making it a straight run but the Orph’ has all its gubbins down below so the fuel has to go all the way up inside the tank then back down to the bilges on the outside where it must then be given a positive pressure before entering the piston pump – hence the tank and boost pump.

Way too many holes to mend in this case but a small brass maker’s plate on the underside declared that it was made by a company called Gallay, which happens to still exist.

They were promptly contacted and asked if they could make a replacement and they immediately said yes – but we waited, and waited, and waited, until eventually we demanded the return of our knackered tank and made one ourselves. There was nothing to it once we got stuck in.

We salvaged as many bits and bobs as we could including the internal baffles…

All the external fittings…

And the ring where the boost pump bolts in.

Here it is ready to move fuel again, and below – as it was when we found it.

The original pump is, of course, fighting fit courtesy of Kearsley Airways and was soon bolted back from whence it once came.

Next in line was the LP fuel cock, which is mounted on another rigid pipe fabbed-up (fabricated) and gas welded by someone at Norris Bro’s back in 66 when the new engine went in. We had the original but it too was cream-crackered so it had to be replaced.

With this lot set up and pressure tested we rigged our ‘aux tank’ (as we call it) to our embryonic engine test stand in order to not only supply fuel to our thirsty Orph’ but also to test the LP pump, aux tank and fuel cock, all of which would eventually be fitted to the boat and expected to perform.

The LP cock – rebuilt by Barry Hares, having eventually been identified as a Saunders Roe part and therefore utterly beyond replacement – was operated with a 15ft Teleflex cable so we had a sporting chance of shutting it down and running like buggery if everything caught fire. But mending it proved a challenge beyond this because no sooner had Barry rebuilt it and we put fuel across it that we discovered, to our annoyance, a microscopic corrosion pore all the way through the magnesium casing. It was just enough to wet the outside of the valve and cause a slow but relentless drip. It took a complete stripdown and the application of fluorescent penetrant to find the gremlin under UV.
