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.

Introduction to Building Your Own Wind Turbine

We are back at Irish Seed Savers in County Clare on Saturday 24th March to give a one day workshop.

It’s a a taster of a build-your-own workshop – the goal is to give you a realistic look at the various parts of building a Hugh Piggot designed wind turbine. We will discuss the various parts of the project, the materials, tools and equipment needed as well as the other components of a wind energy system.

You can try out some blade carving using hand tools to get a feel for the process. Some people are quite happy to undertake a turbine building project by themselves and this introduction will allow you to gauge the skills required and the likely time involved.

We will also discuss the various turbine sizes and the other components required to get yourself up and running.

Balancing the blades in Gort

We were back in Gort on Tuesday 4th of November to balance the blades and install the dumpload.

The balance was out a bit you could tell by the shaking of the guy wires and the tail. The day was nice and calm and we lowered the turbine down so that the blades just cleared the ground and we got it done in no time so she is now balanced nicely.

 

 

We spotted two problems. On the front triangle of plywood the paint has bubbled around the edges where the screws are and it dos not look like marine ply as the wood is also starting to separate the paint is top quality marine stuff and put on by a pro (Flor) so that is not the problem he sanded it a bit and put on some varnish to try and seal it. And there is a little crack on the back of one blade probably caused by a plane or spoke shave going against the grain not serious though we put some glue on it.

 

 

We decided to leave the replacement of the triangle until September and also the blade to see how it all wears but if it looks bad we will do it before that.

The resistors for the dumpload finally arrived six 3.1 ohm 300w wired in parallel and I bent some metal and mounted a slate on the wall behind it so it should be ok it pulled 43a and got nice and hot so the dogs will be happy on stormy winter nights.

 

 

The best power we seen was 42a in a strong wind and dipping down to 18a. All the lights and some sockets are running of it nice and easy and now that all the bulbs are cfls so next visit we will wire all the house except the freezer and dryer looks like they are heading for an off grid house.
