Thanks for the comments guys. 
Fred: They don't squeak, but they do rattle in the wind and can make quite a racket. At least they use to, until I re-did the bearings and got rid of the screws. I replaced them with the smooth shanks of bolts and then put a short piece of steel tube in the prop. Now they run smooth.
Doc: Good idea with the fish pump. :thumb:
Robin: That's a good model ya got there. Nope, none of these run anything, other than my imagination. One day I may build one that really dose something.
I'm thinking about those Dutch windmills now. Hmmmmmmmmmmm?
Here is the plans for an HO windmill. I included a scale HO ruler so you can get the size closer than without one. Print this out and build it out of scale lumber. Mine is made from balsa wood sticks. Place a piece of wax paper over the plan on a piece of Styrofoam or corrugated cardboard, just like when you build a scale model plane.
The blade assembly starts with a small round disk of wood with a pin hole in the center. This is pinned down to the diagram. Then bits of stock are cut and glued to the edge of the disk all the way around. I made the ring out of thin styrene and glued it to the assemly to give it some strength, and the blades but up against it.
Once that's done, then the frame is pinned to something stable. I used an eraser on a pencil, and put the pencil in a vice. The blades are cut out of the paper plan and glued to the frame one at a time, being careful to keep the angles the same. Make the body of the mill as you see in the pic and make the tail fin of your choice. I put a piece of styrene tube down the middle to model the power transfer to the pump below. The axis pin in the body slides into this tube, and the blade pin is glued to the body of the mill.
