I'm really trying to figure out how we can make many wind turbines as cheaply as possible. My experience with carving the 1.2m wood ones for the 500W Hugh Piggot design made me immediately want to tackle this first. Once I have the fiberglass mold, for which I should only need one wood plug, making the blades from fiberglass will hopefully be quicker, need fewer tools, be easier to train someone to do, have more easily repeatable results, be cheaper, and may also result in lighter, longer lasting blades (I think the wood we have available here is a little softer than would be ideal). If I only need to make one plug from wood, then I can take a lot of care and time in making it. Using templates it shouldn't be too difficult to eventually get a more complicated shape like the S822 and S823 employ.
I am aware of a few of the blade carving programs available. One is an excel spreadsheet that is available from Hugh Piggot's site (i believe). I want to understand some of the assumptions being made in these programs in order to be more confident that they are appropriate to use for the two profile blade I am attempting. Basically, if a number of these are going to come out of a mold, and be installed around the country, I want to have some confidence that they are half-way decent. So, sure, there's a lot for me to learn :)[ Parent ]
If that is your goal, then you are asking the wrong group of people. You should be following the proven business model provided by the Chinese. They pretty much have the market cornered on cheap junk.
You also need to remember that cheap in equals cheap out. If you want a quality product, it isn't going to be cheap.[ Parent ]
