<\/a>Once I had done the wood, I made a start on the wind turbine, and that is now in position.<\/p>\nDoesn’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.<\/p>\n
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?<\/p>\n
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.<\/p>\n
So I turned the bolts round so that the threads were exposed – hardly aerodynamic but it all fitted. <\/p>\n
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. <\/p>\n
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. <\/p>\n
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. <\/p>\n
Won’t that be fun?
<\/p>\n
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. <\/p>\n
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. <\/p>\n
I had to lower the anenometer though – the wind turbine was fouling it<\/p>\n
The faster the wind turbine turns, the brighter the light will become. <\/p>\n It reminds me of Doctor RV Jones and his experiments into the cathode ray tube. In his book\u00a0Most Secret War<\/a> Wouldn’t I like to have something like that with this wind turbine?<\/a>Wind 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. <\/p>\n
