One baby step at a time. Make a scoop...learn...make a hood with a scoop...learn...make a body...learn. Make 3 pieces for every piece you will actually use...learn. I've been building things since a child (RC aircraft - old style, not your plastic and Styrofoam wonders of today- and Tesla coils for example), put some common sense and engineering education behind that, and the only limit becomes space, money, and a spouse's patience (but not in that order). Fortunately, this is a hobby, and not a means of making a living, which is why I enjoy it so much. I currently work for a Regional Transmission Organization with the goal of preventing future wide-spread blackouts with our member utilities.
