That's much better, the postscript didn't show the yellow labels, so I wondered already why you uploaded it anyway.

The whole assembly will have 26 parts, no puzzle everything has it's place, but a lot of room for pads, pockets, cylinders, chamfers, fillets, work flow ...
Here is a little teaser:

Re: Windmill project
windmill, no nothing to grind.
wind turbine, no, flat fins not aerofoil profile, energy extracted goes with cube of wind speed.
anemometer, possibly.
toy for children to run around with.
Motivation for post: homework : most probably.
"my friend" GF's homework, hoping to impress by saying he did it for her.
Fun rating 9/10.
Now for the real thing. A Freecad model to cut windturbine blades from Piggot's famous Scottish wind generators may actually be useful. I have "a friend" who went on a course and actually made one from Douglas pine, using a spoke shave. One of my general ideas of getting into cnc was that would be a cool thing to make.

one of the neat ideas in this design is the furling hinge, which automatically puts it side-on in the case of strong winds.
This is a very successful, low tech, design with hundreds of working installations. IIRC Piggot originally got a lot of folks in scottish isles, with no grid, energy independent.
