Rodney Frost’s collection of playful mechanical contraptions will captivate anyone who operates them—and they’ll entice the creative woodworker too, because these whirligigs are as much fun to make as to maneuver. The secret to these movable marvels: propellers and other action-filled parts made from wood or metal. Full-size schematics and drawings, plus detailed written instructions, will guide woodwokers smoothly through building, carving, and assembling such enchanting projects as Grandad’s Night Out, a wild and wonderful gadget with a handsomely dressed figure that dances on a box; the Politically Incorrect Weather House (it contains a hygrometer to measure humidity); and Mr. Muscles & Little Ms. Threemore, two exercise buffs who work out!
