Introduction: Turnabout - a K'nex Windmill
Many a time now I have tried to come up with a design for a little windmill, and this is my latest and most successful attempt. It's a small, simple and stable design that catches the air very well. The best feature of this windmill is the rotating head, which allows the tail to rotate the blades straight into the wind, regardless of direction. It preforms very well in light wind yet can handle very rough and gusty weather. I've left it out for days on end without having it malfunction.
All photographs and video taken in Whiteshell Provincial park, Canada.

That's it! Let's make a start.
Step 2: Tailpiece
Here you will be building the tailpiece. Nice and easy.
1: Build this tail fin
2: Make this middle bit too
3: Connect the two. Use whatever colored panels you wish.
4-5: Build this little bit
6: Now make another identical piece
7: Build this little piece
8-9: Now connect the pieces built in photos 4-7
10-11: Now connect the tail fin with the bit you just made to get the completed tail.
Cheers! On to the head of the windmill.
Step 3: Head
Step 4: Blades
Here we build the part of the windmill that does the actual spinning. Yay!
1: Make this blade
2: Now make seven more. Mix and match colors as you wish.
3: Build this very complicated piece:
4: Add on a blade like so
5: ...Now put on another...
6: Keep going until all the blades are on.
7: Depending on which way you want the blades to spin, you c an flip the blades around now.
8: Build this center wheel
9: Start connecting the blades to the other axle center
10-11: Keep going until you've built the entire blade like so
Step 5: Top Assembly
1: You should have these three pieces
2-3: Connect the tail to the head of the windmill
4: Grab these three pieces
5: Put the two spacers on that black rod
6-7: Slide the blades on and put the cap on the end of the black rod
Cheers! Now put this part aside, and we can start work on the tower section.
Step 6: Crown
Time to start work on the top of the tower. This at the very top of the tower, thus the name...
1: Build this circular piece
2: Make this awesome thing
3-4: Build this little bit
5: Build three more, to get four in total
6-7: Attach the four wheelie bits onto the awesome pieces from photo 2
8-9: Connect that wheelie bit onto the circular part from photo 1
10: Make this pokey thing
11-12: Put said pokey bit through the part you've been working on
13-14: Slide the black panel over the tan rod through its middlemost hole
15: Grab these four pieces
16-17: Put the spacers onto the tan rod and cap it off with the clip
Step 7: Tower
A bit of a longer step. Let's get on with it!
1-5: This long piece constitutes the main part of the tower. Build it using these five photos.
6-8: This is a reasonably bizarre piece that goes in the main tower. Pay attention to the white rods on the bottom.
9: Line up the two pieces that you've made like so
10-13: Now put the smaller piece inside the longer piece (don't put it in upside down!)
14-16: Build this long strip
17-19: Attach it to the other part of the tower (again, be sure to put this in right way up.)
20: Build these long strips
21-24: Connect them in on the sides of the tower. Note that the connectors just sit on the horizontal rods on the main tower, they don't actually clip in.
Way to go! We're nearly there.
Step 8: Feets
We need to put some feet on this thing.
1: Build these two parts
2: Connect them
3: Make three more of them
4-5: Attach them onto the bast of the tower, all connections should be obvious
6: Now make this piece
7: And build three more of them
8-10: Add them onto the base of the tower as shown
One last step!
Step 9: Final Assembly
The final step!
1: Connect the crown to the top of the tower.
2: Be sure to connect the two 3d connectors there
3: Smack the head attachment right onto the panel on top
4: What it should now look like
Cheers! You're all done.
Step 10: Finished!
All done! Enjoy you new K'nex windmill. If you have any comments, suggestions or whatever, leave me a comment!
