each piece was cut to roughly the right thickness with a small skil saw
this removes a lot of of wood but really only is easy with a non twisted blade


then all were glued


then out with the electric planer and sander ,flat blades like electric planers !


then wedges were put at each root to make a constant angle of 4 degrees and a paint job
with experior wood paint the grey bits were added to try to break up the lines a bit


putting in wedges was the pain in the ass bit if one is slightly off the whole blade
(probabely including the plywood hub disks ) is thrown off
each blade needs a wedge top and bottom
the blades are basically the same dimensions as the big gyreum machine but have no
twist in them so some performance will be lost (noise might be gained too). but they were very quick to
make up (and cheap) mainly because only the back side needed shaping hopefully theyle be
tested (or fall apart due to dubious weather proof glue) ) soon]]>

this is the stator for the 3.6 m machine ,coils have 80 turns 1.7 this time and came out a little on the fat side, not much clearance on narrow parts of the mould or between coils but fitted ok (thicker wire and my winding probabely)

after waxing (floor wax) and placing in the fiberglass cloth i slid in coils in the wrong place and had to move them in the mould ,not a good idea as the cloth moved too leaving bubbles underneath , plenty of teeth gnashing at this point , the little fiberglass tabs on the coils helped keep things in the right shape though

24 hours later opened her up and convinced the stator to come out at gun point ,it was tight (probabely not enough wax around the island and rim) came out in the end ok, the back and lid didnt stick at all

next up is the frame and rotors ,
[
the blade hub is for fibreglass props but will be binned as its a mixture of welded cast and mild steel using ordinary rods
this little adventure in welding is probabely an accident waiting to happen
i came across a small engineering shop run by a helpfull man (paddy) who machined up the rotors
from 12mm plate , had a few alignment problems (should have left the hub with him) half an hour with a good file and everything
fitted together ,paddy reconed they were a bit tricker than he first thought (big diameter on a lathe) at the start he recommended
lathing down the plates so i just went along


the frame is to the same specs as gryeum but using as much as possible of the stuff i have lying around
nice and rusty too
next to get some resin ,the magnets are epoxy coated so i might spoil meself with epoxy resin buts its expensive
grs in cork sell an epoxy (3kg) for 62.00 plus vat ,]]>

Hoping to mount on self standing pole (10m) with no guy wire supports! I have modified a steel tilting "street light" pole. The pole is bolted to a concrete base buried below the ground. I live in the City and hope the neighbours won't object!


The pole is a "well used" ex. City Council type, my brother got it from a friend? I welded on the round base plate & gussets. Its attached to the concrete base with 25mm galvanised bolts.



I used just over one 1100kgs of concrete for the foundation base.



Gusset detail



The oval hole in the pole is where the service cable would normally enter, when the pole is buried in the ground. I will run my cable underground via a duct which passes through the concrete, at the pole base.

Pole top detail

Note pole extension (standing on the left of the green pole) to be added on....as soon as I can figure out a way to raise them up!


Final assembly......almost]]> Started building turbine last year, using Hugh's plans. Hoping to mount on self standing pole (10m) with no guy wire supports!

Niall gets the lead out and applies it to the blades

A group of us based in Cork city are looking to build the smaller wind turbine as specified in Hugh Pigotts design. For this we require eight magnets 2"*1"*1/2" grade 35. There are two websites in his design. Both would cost around €100 including delivery for eight magnets.

Is there anybody out there who has left over magnets and would be willing to sell them in ROI?.

Alternativly can anyone suggest a cheaper option, different distributor maybe?

We are not planning to start a project until early 2008.

Thanks,

Garrett Blake]]>

This is me my dad and a neighbour putting it up the blades still have to go on


This is her up and flying making good power all going into heat saw up to 5KW but the tail furling up too soon put some weight on it but still to easily furled up (10-12 mph) no fun
Fried some stuff though including an inverter a controller and a few bridge rectifiers fixed all no problem only really cost me a few quid for the components. Now running 2 tri stars in parallel]]>

I was just talking to Tadhg about magnets. I'm sure a few of you are looking for magnets - so I suggested maybe you could pool together and order a batch from china, which is probably the cheapest option - at least for people living relatively close.

I've been pretty busy in my studies, so I'm sorry I didn't get over to help put up the large turbine again - everything went well I trust.

After all my efforts I hope you will all try carving your own blades, but if you are having trouble or can't source the wood - I am going to carve a few sets of blades for the smaller machine (out of my Austrian Larch of course).

Any one have any tips on joining the 3 wires together they seem a bit bulky I saw on otherpower that they used strips of copper and crimped them and then soldered.

Coils wound and ready for soldering I made two bad ones one was to loose ant the other one was to light I must have miscounted it is a good Ida to weigh them.

Johnny guides her up


The weather was starting to blow in the morning and by the time we had the machine together we had a nice NW gale it's not a good idea to put up turbines in a gale but we plowed on and up it went and the minuet the brake was released it furled.


We saw over 23 amps at 56v it was averaging around 10A it was hard to photo the amp meter at it's best but Miriam got this shot of 20A there is a shadow on the left the true needle is the one on the right.


I liked the way it handled the strong wind very good design Hugh.
