Is Cranfield going to be the venue for some runs with the engine then?

I have to compliment Mike, John and Youth on a landmark event and a job of outstanding quality and attention to detail. They've spent the whole day fitting the right-hand foredeck and what a magnificent sight it is too. Well done, guys, and thanks!

You're kidding yourself too... They'll be halfway riveted by then!

I've been to Birmingham this weekend to meet again with Barry Hares. He's mended the last valve in K7's original air-start system and that he's been able to do so is simply astonishing.
The valve is a tiny thing you can hold in the palm of your hand that releases the main air valve to start the engine. The 'piggyback valve' as it's called has a stainless spool down the centre that moves only 0.006" through a nest of nylon valve seals and o-rings when you press the go-button and it was badly corroded internally. I don't dare take it apart to see what he's done in there but there's a cap on the end the shape of a shot glass that covers the solenoid and the side wall is 0.5mm thick. It was split by a buildup of corrosion product inside that burst it down one side so Barry simply machined it to half its original wall thickness and popped a sleeve over the outside. It leaves you dribbling...

For anyone who's not yet seen Barry's work take a look at this... http://modelenginenews.org/gallery/crof ... index.html I've seen this engine for real and it's in a display case about the size of a microwave oven!

We're extremely lucky to have Barry's help and support with this.

Now that is what I call properly stunning! A H configuration, 24 cylinder two stage supercharged engine displacing 360cc! In a just world, that sort of skill should be worth a lot of money.

I used to think that I was a handy engineer, but at best would probably just make the grade as a fitter, second class!

Yup - I've had a lot of that lately. The guys at Goodrich and R-R gave me the same treatment with the shot-peened, pre-stressed springs in our fuel pump but Barry is in a league all of his own.
What you can't see from the photos is that at the back of the engine is a complete set of 1/5th scale working instruments along with lube oil tanks, electrics and coolant rad's. Nor can you see by looking that the magnetos each contain coils wound from the earpieces of mobile phones using wire 0.001" in diameter and that they can deliver 48 sparks on each revolution to Barry's 1/5th scale spark plugs down those stainless braided cables. It's absolutely mind boggling, it really is. And what delightful, welcoming folks Barry and his good lady are too. It's a privilege to know such people.
