On this page there are lots of pictures of the blades. Most people seem to think that the blades are very hard to carve, but if you follow the plans and take your time, they are really pretty easy to make. You do have to be careful not to remove too much wood at a time. It’s easy to take off a little more if you need to, but it’s really hard to put it back on once it’s off!
Balancing the blades is also very important. If they are out of balance when you put the turbine up, you will notice quite quickly. They will not track perfectly and there will be a lot of vibrations in your tower. This puts undue stress on everything and you will end up with problems.
There are several ways to get the blades to balance almost perfectly. Some of these ways will be explained on this page.
