My bearings lasted three days..... (I used the same generator in my first version - albeit belt driven from one side).
The trick I used to get the thing apart was to undo the 48 bolts on the largest diameter, on both sides, leaving the rotor inside the stator, just removing the bearing end face plate. No presses needed. Make sure you do it in a clean, non dusty, environment, as swarf will get picked up by the super strong magnets.

Noel how dare you refer to our most prized tree as a "stunted shrub" Ah Bonsai ! sorry. I see why you might consider burning telegraph poles though. Adam, how much generator hum do you get?
Depends what mood it's in Now thats the kind of answer I love  |

Billi how come your trees have grown up vertically yet the stunted shrub under Eleanors blades of doom, has grown sideways ?  Now that's a proper 'west coast' tree, just like the telegraph pole on the right, most things up here, including phone boxes have a list toward the north east  |

Adam, how much generator hum do you get?  Difficult question to answer, it only hums when the wind is gale or near gale force and strong winds. thanks adam I'm going to sell my 1.8m 6 blade and hub set if anyone is interested let me know, they retail new at £325 inc postage on ebay, serious offers thanks  |

Adam, how much generator hum do you get? Depends what mood it's in  I hadn't realised we'd bought a turbine with attitude!  Adam, interesting that yours only hums at high speeds. On the odd occasion Mindy deigns to rotate (0.3 m/s at the moment) she definitely hums and it's quite noticeable at 5 m/s. We haven't really had the opportunity to hear it at 7 m/s when the wind is supposed to be louder than the generator. The blades just make a swishing noise which is fine  Now that's a proper 'west coast' tree, just like the telegraph pole on the right, most things up here, including phone boxes have a list toward the north east Paul, if you look carefully you may see yourself just to the left of the telegraph pole  |

Hi Adam,
what size of battery bank are you running from the miniwind, or put another way, what size bank is the miniwind capable of supporting. I know that in terms of chargers the bank should be charged at a minimum of 10% of the capacity, ie 50Amp charger 500 amp battery. How do you size a bank to a turbine?
thanks, Alan

Hi Alan, i'm useing a 2nd hand ex forklift battery @480ah not sure how old it is so it probably has a few dead ah's but £200 i'm not complaining I diddn't size the battery to the turbine i just bought the best value for money, it works very well |
