Wind Turbine Maintenance

We noticed a knocking sound from our wind turbine and thought it might be a disk rubbing on the stator but the problem turned out to be the nuts that were holding on the blade assembly. Two had disappeared and of the two that were left only one was tight. There is no chance to see if the missing nuts fell anywhere near the mast as the ground is well covered with snow at the moment.

You can see in this photo that the holes are a bit gouged out by the movement of the blade assembly.

The washers were all dished.

The tail is a bit of an experiment and the turbine has been flying with it since November. It’s heavy gauge plastic coated corrugated sheeting, dimensions are 98x72cm and it is around the same weight as the recommended plywood tail. It seems to be furling on time but could be a bit bigger for holding the turbine better into the wind.

We used bits of aluminum as washers to try and stop the bolts from splitting the sheeting which could be a problem because of vibration but so far all looks well.

Wind Turbine Workshop with Hugh Piggott June 2012 in Leitrim

Once again we had a wonderful “Hugh Piggott – Learn to Build Your Own Wind Turbine” workshop near Keshgerrigan, in Co Leitrim. We had a great site for the workshop on a few acres of Leitrim countryside, luckily in an area that the midges were not too familiar with. There was camping accommodation available for the workshop participants who wanted to stay on site and many did camp.

We had a purpose-built, fully equipped camp kitchen – the most important piece of equipment was Sue, the workshop Cook Extraordinaire! We were lucky with the weather and were able to dine outside most days. Sue’s Alive ‘n’ Cooking Cafe, was also a very popular place to stop for a coffee and a chat during the day.

We had an international group again this year with some people traveling many miles – from as far away as Cork and China!

We built a 4.2m 48volt turbine for the farm that hosted us, using neodymium magnets and western red cedar for the blades.

We also built a 2m, 24volt turbine, using ceramic magnets and a different blade profile (also western red cedar), that we will erect at Eirbyte to monitor for the next year or so.

The workshop had a musical flair with impromptu sessions held many evenings, around the campfire when the weather permitted and in the workshop building when it was rainy.
