Tuesday 19th August 2014 – WELL I’LL BE …

Yes, absolutely!

Just about to go to fetch some cable trunking out of Caliburn this afternoon when a big red Honda motorcycle pulled up just outside here. A lady descended from the rear and smiled at me, which was a surprise – not something that happens every day – and then the driver came over, shook me warmly by the hand (which was also a surprise – regular readers of this rubbish will remember that most people who come here usually shake me warmly by the throat) and said “Jean-Marc”.

Well I am actually Eric, as most of you realise, but it turns out that the motorcycle rider was called Jean-Marc.

You may remember that several weeks ago on the way back from Munich, I called off at a village called Chasselas, near Macon, a village where I had stayed with a French family in my mid-teens. And now Jean-Marc, the son of the family, had come over to repay the compliment.

Yes, it’s totally astonishing. It’s 44 years since we have seen each other. And it was totally unexpected and I wasn’t in the least prepared, with stuff all over the place here. Good job that it was sunny so that we could sit outside. If it were raining, it would have been very embarrassing.

And sunny too – that’s about three days now that we’ve had some sun and I’ve had hot water. Too late to do much about it now – Jean-Marc was telling me that the grape-harvest in Macon will be a total disaster this year.

But this place is even more of a mess than usual. There’s stuff all over the place while I’m working out what to pack to take with me. And I also forgot to charge up the video camera so I had to do that as well.

I’ve also been trying to download off an old dictaphone some soundbytes – one of a Canadian diesel locomotive and and the other about a peal of bells from a Canadian church. But for some unknown reason, the lead that I have to connect the dictaphone to the computer isn’t picking up the sound. I’ll have to look further into this.

After Jean-Marc and his girlfirend left, I still had time to go up onto the scaffolding and throw piles of stuff off the top. That seems to be the usual practice these days and I was up and down the ladder for most of the evening.

But now, I have outside lights underneath the eaves to light up where I usually fall over everything when I’m out after dark. And they work too, much to my (and everyone else’s surprise). And all of the cables are in trunking made from 32mm water pipe and it all looks quite tidy, which doesn’t ‘arf make a change around here.

And no gardening today as I promised?

No, because Rosemary telephoned me to say that she might be round on Thursday. We can pull up the onions and everything else then.

Friday 27th January 2012 – I CAN ALWAYS TELL …

… when I’m enjoying myself when i’m working. It’s when I suddenly notice that the light has gone and it’s 18:15 and I’m still out there happily working away.

And so it was today

I did the customary pile of woodcutting and now the woodshed is looking quite impressive. There’s probably now enough cut to last me for next winter as well and there’s still a load to do out by the barn.
And then there’s all the wood from last winter, that’s still down the fields.
And then there are all the chevrons off the house roof and the barn roof.
Wood isn’t something that I’m going to be short of for a while

Doesn’t it look smart with its new stylish aerodynamic blades. But I shall have to stop mounting all of these wind turbines. I’ll end up being arrested.

It wasn’t as easy as you might think, organising this wind turbine. But then again, nothing ever is when I’m involved, is it?

It all started to go wrong when I tried to mount the hub onto the spindle. And immediately the bolts holding the blades to the hub fouled the casing.

So I turned the bolts round so that the threads were exposed – hardly aerodynamic but it all fitted.

Then, tightening up the hub, the hub ground out against the casing and locked up the blades. That meant using a couple of packing washers underneath the hub.

One I had, the correct size of diameter, I had to file out the hole to 19mm. The second one, I had the correct sized hole but the diameter was wrong so I had to grind the excess off with the angle grinder and the bench grinder.

So instead of an interference fit, I now have three extra faces and so under a great deal of wind pressure, I can see the faces sliding instead of the blades turning.

Won’t that be fun?

Much to my surprise, the wiring was pretty straightforward and didn’t call for any major revision. But putting it into position was something else. I didn’t have a scaffolding pole long enough and so I had to join two together and that’s no fun trying to do that on a ladder with that kind of weight at that height pressing down on your shoulders.

It’s for that reason that, after much cursing, I invented the wind turbine pole lifting handle, and I was astonished at how easy it was once I had a lifting handle in place.

I had to lower the anenometer though – the wind turbine was fouling it

12 volt external electrical wiring air 403 wind turbine les guis virlet puy de dome franceWind turbines need a load in order to work, and so I’ve wired it directly to an external weatherproof 12-volt socket, and to the socket I’ve wired a 12-volt 100-watt halogen light.

The faster the wind turbine turns, the brighter the light will become.

It reminds me of Doctor RV Jones and his experiments into the cathode ray tube. In his book Most Secret War, one of the best books I have ever read, he describes that they tentatively connected two lorry headlights to the tube, hoping for a faint glimmer of light. Instead, they managed to illuminate the whole building before the headlights blew out with the intensity of current.

Wouldn’t I like to have something like that with this wind turbine?
