1. Base (15 x 100 x 150 mm) mark out and saw the corners as shown. Sand the corners to nish.
Instructions
2. Support wedge (20 x 20 x 80mm) cut this from the wood strip 20 x 20 x 350 mm Sand to nish
3. Saw the strip to 270 mm long
Drill the ø 4 and 6 mm holes as shown
4. Insert a bearing sleeve 6/4 x 20 mm in the 6mm hole drilled in the strip.

10. Cut the plastic foil for the sail into a square as shown. Mark out the diagonals. The circle shows, where at a later stage, the
cuts go. Use a hole punch to make a 4mm dia. in each corner as shown. Cut the foil down to the circle and then punch a
4mm dia. hole in the middle
11. Fold the windmill : fold all the corners with holes into the middle.
Insert the machine screw M4 x 70 through the 4mm diameter hoes from the front. Slide on the ø 40 mm wooden disc and
then x with a nut as shown in the diagram.
Note : Be careful that when tightening the nut , that the shape of the windmill is not distorted!

12. To continue, slide a washer up to the nut. Insert the machine screw in the bearing in the stand and on the other side add a
further washer and nut. Tighten and adjust the assembly so that the sail can spin freely.
Now add the single large wooden disc and tighten it with a nut. Add a further nut to make sure its tight (Contra tighten )
Note: The sail should still be able to spin freely in its bearing!
Add the hand crank and tigten it with a nut. Again use an extra nut to ensure that it stays tight
Note: The crank handle and the large pulley should be really tight with one another but the sail bearing assembly must spin
freely otherwise it will not be able achieve opitmal power transference
13. Add a washer to the other M4 x 70 machine screw. Insert it through the
free hole in the stand. Then add another washer and two contra tightened nuts so that the screw is held tight and cannot
turn. Now add a washer the two pulleys, another washer and again two contra tightened nuts
Use the nuts to addjust the pulley so that it can spin freely
14. Fix the motor clamp to the base as shown ( Page 3) with the 3 x 12mm chipboard screws
Take the black cable from the motor (+) srtip the insulation from the end and wind the wire around the Anode ( Longer leg
of the LED )
Take the red cable (-) from the motor ,strip the insulation and wind the wire around the minus leg of the LED ( shorter leg).
Fix the light diode with 2 drawing pins to the base as shown
Push the pulley and reducer on the the motor shaft Slide the motor in the clamp
Note: Note there is no electricity owing between the parts ( current )!
Stretch the rubber bands over the pulleys (rst the top and then the bottom)
Turn the crank handle, then the LED lights.
