Ah, to be young again…
Cliff, you keep building and I will keep posting. Thanks for the welcome and I look forward to seeing more.

Wow! Very cool to have it working. This model would not be out of place in a museum!
I agree on the In-ko-pah RR …
Cliff you simply amaze me with your abilities. First your CAD skills, your drawings are art work in my opinion, and then your working models are just second to none. Beautiful as always.

Absolutely amazing. Now all you need is a windy day to take it outside and see if it actually works as intended…(https://www.largescalecentral.com/externals/tinymce/plugins/emoticons/img/smiley-wink.gif)
OK Ken, you made me try it out, haha! At least an indoor test, with a fan.
That is really cool Cliff. Amazing work that actually works…the best kind.
Wow, that is really neat to see it in action!!!
So, what is it actually doing? (Pumping Water, Grinding Feed, Sawing Wood, or Etc?). (https://www.largescalecentral.com/externals/tinymce/plugins/emoticons/img/smiley-foot-in-mouth.gif)
Well done, Cliff!
Cliff;
That turbine is just amazing to watch. You really have it balanced well.
Best Wishes, David Meashey
Supposed to be pumping water. But its probably just wearing in the bearings. Cliff hasn’t printed out a working water pump yet. I think that is next week’s print job. Or maybe the week after that.
Where are Dorothy and Toto when you need them? Super cool. One wonders how it performs with a real load, aka a pump. Presumably start up is slower and slow down quicker… more things that are hard to model at scale.
Cliff that is just so cool. Now you made the comment that the turbine is heavy and takes time to get to speed. I wonder how the weight of your model compares to the weight of the real thing. Does it scale out heavier or lighter do you think?
No I want to see it pump water. Make a working pump and you might catch my attention. . .yeah right. simply cool my friend.
That is just way cool, Cliff. One other benefit of the shutters is that it forces the air to cross the turbines at the same angle, so you don’t get any drag by the wind blowing on the left and right with the same force thereby canceling itself out. Now we want to see it pump water.

Just a wee caveat regarding scale things trying to do real world functions. Sometimes the intended work does not “scale down” very well. Real water may need a bit of “lubricant” to make it flow better through a tiny pump. In many cases this “lubricant” may take the form of a hand dishwashing detergent. (Could result in suds coming out of the water tank!)
Personal experience: I thought it would be neat to have an actual steam whistle on my Regner DeWinton type live steamer, and Regner offered a whistle and whistle valve. When I got said whistle, it was about the length of my pinkie finger, and probably would compare to a fifteen foot bass organ pipe, were it full scale. (If the whistle were smaller, perhaps only dogs and cats could have heard it.) Undeterred, I mounted it on top of the vertical boiler of my little live steamer (see photo below). I was running the locomotive and decided to blow a grade crossing signal (Two longs, a short, and an extended long.). I RAN OUT OF STEAM! I sold the whistle to somebody with a large boiler locomotive at Steve King’s next steam-up. Lesson learned.

All the best, David Meashey
Dave:
Yeah, scaling is pretty tricksy. Mass scales with the cube of the scale factor (assuming you are using the same material, which we often aren’t). How would friction scale? Seems like the wind force would scale with the square of the scale factor. Everything is just scaling at radically different rates.
Your story about the whistle is pretty amusing (to somebody else, in retrospect :-)) and is a nice illustration of why scaling is not so easy. Physics! Drat!
Cliff,
Absolutly beautiful model, congratulations on researching and building such a work of art.
Off topic a little;
In your first video at about 21 seconds in I notice a Misery Whip on the wall above the door. Wondering if you had the history on this saw, as the tooth pattern makes it look like a “Californian” produced by the California Saw Works of San Francisco. Is it a 7’ blade as it looks or is it an 8’, just curious how this saw may have ended up on the East Coast. Or maybe just an early knockoff??
Just wondering
thanks
Rick
Awesome!
Well Cliff, I was only kiddin, but thanks for demonstration. Pretty kewl how that works.

Thanks Eric, and I’ve sure appreciated your working projects, like that amazing handcar.

Thanks very much Bruce! I hope to show it at the ECLSTS D&B, will you be there?
This particular one, as David Maynard said, was solely for pumping water. But they were also fitted with line shafts to power various equipment.

Thanks Rick, that means a lot!
That saw measures about 66" long, and I bought it for $20 at an out-of-the-way antique store somewhere in Pennsylvania. I’m afraid I have no story about it.
