There are two separate windmills here, which turn independently of each other and also in opposite directions. The smaller (red tipped) windmill is in front, the larger (yellow tipped) windmill is in back. The entire project is 33" wide. All hardware is easy to find or fashion. Simple to make using the FULL SIZE PATTERNS, shop notes, exploded diagram, and paint by numbers guide our plan provides. If you'd like to build more than just one or two whirligigs, be sure and check out our Whirligig Value Packs -- we've got a great deal on 12 projects!
