Yea, that is why there is an OSHA…
Wow, what an interesting and unique project! I’ve never heard of these turbines before.
Also, the video of the 1000-year-old Iranian wind turbines was fascinating too. I didn’t know they used that technology way back then, much less that any of it still existed.
This is most of the main turbine framework, with the bearing box in the center.
Nifty!

When are you going to market your kits?(https://www.largescalecentral.com/externals/tinymce/plugins/emoticons/img/smiley-wink.gif)
I was taking some time to come up with a funny / snappy answer John, but am officially giving up! No kits I’m afraid… But thanks for the nice compliment. (https://www.largescalecentral.com/externals/tinymce/plugins/emoticons/img/smiley-laughing.gif)

Thanks Ray. And as of maybe a year ago, I wasn’t aware of them either. And yeah, aren’t those Iranian mills incredible?
Today’s effort was completing the turbine frame:
I wanted the main exposed bits to be real wood, and was glad to see the pre-cut parts going together ok, with maybe 10% rework.
As you can see, there is an upper and lower core that, with all these moving parts, needed the precision and stability of lasered acrylic. These pieces will get bearings for the shutters, drive shaft, and main turbine shaft.
I also got a start on the water tank, roof, and rotor assemblies, and will post on those tomorrow. (I’m taking a long holiday-vacation break for this, and have 3 more days, woo hoo!).

Isn’t it nice to have a stretch of modeling time!
i like the exposed wood around a precise core. Nice!

Jealous !!
Looking good!
Today was spent getting the smaller structures assembled. Here’s the rotor, and after a few other attempts, this is how I got the blades to stay in place while putting on the other end.
And here’s where the rotor and water tank go…
Mo’ tomorrow.
So the inner vanes are fixed and it’s the outside vanes that adjust to let in more or less wind… did I get that right?

Hey Jim. Yep, that’s right. The outer “shutters” (not installed yet) open / close like you say; but the inner vanes, which compose the rotor, spin as a unit.
Cliff I am way behind in your project, which is looking very cool.
How ofter do you clean your mirrors?
Dennis
Hi Dennis, thanks. I cleaned them only a few times, and not at all the first year. I’ll be more careful with this new set!
Maybe dust on the mirror gets burned in?

Cliff, I hate to point this out after all that hard work getting the vanes in place, but upon careful examination using very scientific instruments, I believe the angle on the bottom most vane slot is off by 0.000314159 degrees. I mean, come on, if you can’t do better than that, what’s the use? (https://www.largescalecentral.com/externals/tinymce/plugins/emoticons/img/smiley-wink.gif)
All joking aside, this is a very interesting project and as usual your magnificent modeling skills are on display. Thanks for taking us along on this journey.
Cliff I understand the white jig with the cable ties but how do you remove the white part after the brown end cap is installed, this really a neat project, Bill
Haha! Dan, believe me, everything’s off WAY, WAY more than that! But thanks for your generous compliments, which I’ll have to share with Mr Laser, haha!
Hi Bill, thanks. About the center piece, I just broke it up with dikes once the cement set.
I sort of thought that but your jig looked too perfect to destroy
I agree, it felt weird breaking it up, but… I got over it. (https://www.largescalecentral.com/externals/tinymce/plugins/emoticons/img/smiley-laughing.gif)
Honestly, it was the only way I could think of putting it together, after several attempts without it.
