Bruce, The woodworking part is no problem and have a drill press and hand files/micro files for light metal work. I could do some light "machining" or modifying of "off the shelf" pulleys that just needed the shaft holes tweaked, or tapped and threaded. I don't have a mill or lathe to machine raw stock or know anybody locally who does. (We just moved and haven't met many people here yet.)
Brian, I hope you are able to learn what you need from this thread. Nice to know that you're dealing with a similar challenge. These windmills are really nice projects and worth the effort!
