Have put the two previous projects on hold and proceeding with this one. A Razor electric scooter components from roadside pick up. Amazing what people throw away, all this needed was a new battery. 24V 100W DC motor Sprocket and chain drive will be modified to suit. Blades cut from 100mm PVC pipe. ![]() ![]() Edited by Nightjar, Thursday 12-04-2018, 17:18.

Progressing slowly, but not with out a few set backs. Used YouTube to model the blades, the fella displaying in the video spun the the propeller of his finished product by hand "Clockwise" WRONG!!!!! Out in the wind that design actually spun anti-clockwise. Anyway after walking away I came back to the project and it is now progressing well. Spinning Clockwise. Will now have to modify the Razor frame to adapt the turbine and chain drive to the 24V motor. ***Watch this space**** ![]() |

Gardening and other priorities are slowing the project down. Have now altered the razor frame to hold the turbine and 24V motor in place. ![]() Blades now fitted to hub and balanced the best I can with what I have. ![]() Edited by Nightjar, Thursday 12-04-2018, 17:19.

No problems with that Jim, When I was a lad only had kerosene lamps and Metters wood stove that my dear old mum used to cook on Summer, Autumn, Winter & Spring. If you wanted some cool relief in summer you opened the windows & doors?? Thunder box down the back yard, windmill pumping to a tank, the only running water was to the bath/shower, water heated with a chip heater. We had 32V power in the last years on the farm, a nearby family installed a Dunlite my fascination with wind power probably began back then. Moving forward to the 90's, I spent hours in the shed building a large wind turbine for our bush camp, unfortunately it was a failure. Have a photo here some where. ![]() Edited by Nightjar, Thursday 12-04-2018, 17:19.

Cut, trimmed and welded razor frame to mount the whole unit. Took it out in front garden to face the 22 km/h to check output with multi meter. Back to the drawing board, the little motor takes more power to drive than calculated. Will have to cut out three more blades, will use 150mm pvc and make them a little longer. The chain drive probably uses up a little power as well. Our greatest glory is not in never failing, but in rising every time we fail.– Confucius |

What would we do without Bunnings. Managed to get a metre length of 150mm PVC, saved heaps not having to buy full length. Have marked out 4 blades. (One for a spare.) You can see by the image there will be a much bigger area facing into the wind, hopefully this time we will see a few amps being produced. Cut them out tomorrow and proceed from there. ![]() Edited by Nightjar, Thursday 12-04-2018, 17:20.

This Peter, like all your diy projects, is another interesting one. Just a query on the motor you are using, am assuming it has a perm. magnet field and a commutator armature. It will generate dc electricity, but how do you control the output voltage on a near fully charged battery other than by a resistance bank. The windings of the unit may be such that a very high voltage potential is available which can destroy a lead acid battery very quickly. The marine wind charger units seem to use a car type direct driven alternator which can be fully controlled by an electronic regulator. This type of alternator starts generating as soon as rotation commences, the out put is dependant on the rpm but then by the volts/amps fed to the rotor which is the electro magnet exciting the field output circuits. The one we had on our boat was fully sealed but I think there was a centrifugal switch in the hub that supplied current to the alternator armature windings to start charging and prevent drain when the blades were not rotating. Following your latest project with interest.... Here on the ranges many wind turbines are being erected. The blades arriving on special rear steer semi tailers, each blade is 69 metres long.....bit more power than you are anticipating Michael |

Your comments are always interesting as usual Michael, A very wise boat builder said to me many years ago when I was about to build an 18 foot bondwood/fibre glass run about, to which I later fitted a then relatively new Kiwi Jet Unit powered by Holden engine for propulsion. "Don't worry your self about building the wheel house while you're laying the keel." How true this was, when I lay down to sleep many times my mind was racing on how to tackle a task ahead, my thoughts flicked back to the wise man and sleep came peacefully. 14 months later my little ship was launched, much to the ire of the other boaters with their inboards and out boards I could scoot across the mangroves, run up onto the beach and step out on dry shore. When I have this wind turbine spinning and reading the output I'll probably pick your brains about how to regulate the amperage output. Experimented with car alternators on that failed monster I built for our camp. We could never get enough speed for the alternator to kick in and charge. As matter of interest to try and gauge what rpm was required we used a 1/2 drill and an rpm readout. Can' remember rpm details but when the alternator kicked in it was very difficult to hold the drill and not have it spin out of our hands. We burnt the drill out. Most car alternators have to have mods done to the windings to make them suitable for wind turbines. As you probably well know alternators produce AC power which is then converted to DC using diodes. Brushless DC generators, as you mention have permanent magnet etc. One step at a time, Michael. |

Cut out the new blades this morning, after deliberation, going to fit 4 blades this time. You can see by accompanying photo the blade area is considerably greater. ![]() Edited by Nightjar, Thursday 12-04-2018, 17:20.

Mind ticking over this morning over a cup of coffee. Will try and use a little more of the Razor with this project. The steering has a bearing that I'll utilise to keep the turbine into the wind. This slip ring will keep the wires from getting tangled.![]() Edited by Nightjar, Thursday 12-04-2018, 17:30.

Fitted blades to drive hub this morning, attached motor and chain. 15km Southerly barely ruffling the leaves, held the unit up into the breeze and the blades begun to rotate. Will try later when the Fremantle Doctor arrives, am confident that we are going to see results on the multi meter. Next step, round off edges of blades and fit them permanently. Then back to the drawing board and work out how to construct a portable post to fix it too using the steering assembly from the Razor. |

A few photos showing the slow progress; Front forks going to be incorporated in 360° rotation to combat wind change. With some more thought a tail has to be connected to keep it into the wind. ![]() Generator and chain drive mounted on on upgraded propellers. ![]() View of blades, will have to put the thinking cap on to come up with a cone to deflect the air from the flat hub mount face. Laying on one of the blades is a 12V globe that I'm happy to say illuminates when spinning the propellers by hand. This is very encouraging considering the low revs! ![]() Edited by Nightjar, Thursday 12-04-2018, 17:41.

What are you going to do for sliprings? Or are you just going to let the power leads from your wind generator to load wrap around the mounting pole? Or aren't you up to that stage yet? |

Hi Greybeard, Post #16 shows the slip ring I'm going to incorporate in the construction. (No tangled wires.) Sat down and worked out the next step today, should be something to show in a week or so. |

No worries GB, Sat down today and had a ponder about the next move, do believe it is panning out very well using the Razor leftovers to move on with this project. The next move is happening soon. |

Got a couple of hours in today, moving ahead on this project. Reversed orientation of the steering yoke to incorporate some of the frame and bearings to mount the tail. (The motor/generator may look out of alignment, the mounting screws have not been fitted and tightened.) The slip ring will eventually be mounted permanently so there will be no problems with wind direction change. (No tangled wires running to battery) Steady, steady it is is slowly getting towards completion. Now have to probably experiment on what size tail is required to keep it pointed into the wind. Couple of photos different orientation. ![]() Explanations inserted to what the plan is, may change tomorrow. :-) ![]() You can see I have reversed cycle frame to be able to align tail behind the propeller, removed the steering stop bolts so now the unit can swing each way and all, 360°. With slip ring in place no twisting of the wiring. ![]() |

Hello Jim, Project on the back burner for the time while we get ready for our time away + a few other priorities around the house. Have the tail and support ready to fit but it will have to wait. Will update as and when progress is made. Peter |
