Get step by step instructions on building a windmill online.

My son recently had a science project that required him to build a miniature working windmill. To be honest, I thought that this was going to be a very difficult task, however after doing some research on the Internet I found step by step windmill building instructions. It was pretty neat because it could be applied to a full size windmill or to a miniature (which is what he was building). My son got really into it and ended up building a farm house and accessories along with the windmill. I am happy to say that he received an A on his project.
