Book excerpt: An old favorite gets a fabulous freshening up, with full-color images throughout--but the projects remain as wonderful as ever, appealing to children of all ages. Bulldozers, dump trucks, loaders, and forklifts, each with a variety of moving parts: all these toy vehicles are included for the making, with plenty of diagrams, very detailed instructions that proceed logically and clearly from part to part, and images of the final product. Try a box trailer with a semi-cab, doors, axles, wheels (with simulated tread, if you like), and mud flaps. They're fun to craft and fun to receive.
