Windmill Kit, no longer supplied..  

Tail Assembly

With the windmill bearing plate secured level ( normal operating position ) in a vice, slide on the tail assembly. It should point directly backwards from the propeller. Viewed from behind the windmill, the tail assembly will rotate to the left and up. Clamp the tail in place and mark the three drill holes in the end of the tail arm using the tail fin as a template. Make sure the tail is vertical. Drill the holes and bolt on the tail, again making sure the tail is vertical.

Tail Rope. Tie a length of 5mm+ rope to the end of the tail. This is used to pull the windmill out of the wind, or unwind the drop wire every few days, depending on how often the wind changes direction in your location. Use a tennis ball on the end of the rope, cut off at about chest height ( once the windmill is up in the air ).

Yawn Adjustment. The tail can be adjusted to yawn at higher wind speeds by adding weight to the tail.

Final Assembly
Bolt a 3 phase rectifier ( from a old car alternator, click here for more info ) to the bearing plate. The rectifier needs to be in a open location where it will be cooled by the wind. Run 3 wires from the stator connections to the rectifier AC connectors, use 4mm core or better wire. Run 2 wires, black and red ( - & + ) from the DC out of the rectifier. This is the Drop Wire, and needs to be long enough to at least reach the ground from the top of your windmill tower. Secure the drop wire to the bearing plate with cable ties, allow a little slack to the rectifier.
Mast Suggestions

Below are suggestions for mounting your windmill. There are many links on the internet about mast design and location. I prefer to use a folding mast, as it makes windmill maintenance or repair easy. You windmill needs to be in a open location, away from or above any building, trees, or anything that may affect the wind.

Do not mount the windmill on the roof of your house! The Fisher & Paykel stator generates a cogging vibration when spun. This vibration travels down the mast, and can be felt in the ground several feet from the mast base. If you were to mount this windmill on your roof, the noise will be unbearable.

We highly recommend talking to your local structural engineer about your windmill mast. They will be able to recommend footing requirements and design, mast construction and any local council requirements. You local council may require you to apply for a permit.

But as a rule, build your mast stronger than you need to. There is nothing more scary that watching you own windmill during a storm and praying that it hangs together, and nothing more rewarding when it does.
