"Build your own wind turbine"
Hands-on course building 2 wind
turbines with Hugh Piggott and Conor Coady

Irish turbine builders here.

these pages public.
The Gyreum is a really far out
building on a hilltop in the northwest of the Irish republic. Out
host was Colum Stapleton, who built it. The inside is a large circular
hall with subdued lighting. Around the edge are bedrooms,
kitchen, and bright verandah spaces. The fact that there were 3
bright spaces off the central gloom made it perfect for me because my
course has 3 areas of activity:
Blade carving, electrical,
and metalwork. I have made a page for
each and you can find them with the links on the left.
We finished a 3.6 metre (12 foot) turbine and got a long way toward
building a 2.4 metre (8 foot) one too. Most of the folk are in
shot below. And so is the big windmill.

Below is Colum (on the right) looking at his new anchors - treated
strainer posts buried four feet down. The guy cables are
3/8" chain. It was interesting that most of our conversations
used inches rather than millimetres but I reckon the irish like myself
find inches and feet work well for rough sizes, whereas millimetres
work well for precision.
The digger filled the holes back in and gave a good tug on the chain to
get the anchors bedded in.
We were building two towers for the two machines but only finished
one. The idea of the smaller turbine was to make sure and keep
everyone busy. The idea of the bigger one was to get a turbine up
and working, so that was always my main focus.
The towers were built using 4" pipe with smaller pipe extensions on the
top. Colum did not want more than one set of guys, so I suggested
that 4" pipe would be rigid enough for this. The pieces were only
7 metres long but Irish planners allow you to erect 10 metre towers
without seeking permission so we extended the towers to 10
metres. 20 metres would have been better, since there are a few 7
metre trees around but we did what we could. It's a hilltop site.
Here is a photo of the inside of the Gyreum on Friday at lunch.
One nice thing about the place was the high ceiling that allowed us to
swing a 12 foot blade and balance it in a draught free
environment. If you look closely you can see the nice ladies who
fed us all week, Adel and Diana. We ate very well.
Even with the stud nuts loosened, it took Stuart with the big hammer to
get the blades onto the alternator.

course on Scoraig back in 2001.
Stuart doing some last minute adjustments to the tail hinge stops.
The air gap is pretty big. I underestimated the power of the
magnets here. Notice also that the alternator is mounted forward
from the yaw and the stator mounts are nothing to do with the yaw
bearing pipe. The tail uses large pipe-on-pipe inclined hinge
system, with stronger mounts than I used in France.
The Eirbyte Tirfor makes the hoisting easy.
Below Colum finally gets his camera out. On the right, Hugh,
Caoimhín, Ultan and Stuart share a joke.
More shots of the completed windmill...
As usual my camera bent the blades rather badly in the shot on the
