A how-to-do-it book which would be more useful in a community where the Junior High School has a good shop than in home use. The author tells how to build practical things like bike trailers, wagons, scooters, jeeps, racers, toys for younger children. The materials suggested are scrap materials for the most part. There is a fairly formidable list of tools. There are general instructions for procedure and for each article, specific lists of materials, construction instructions step by step, a diagram. A substantial amount of space is given to the nation wide Soap Box Derby, with plans for a racer, rules of contest, and so on...School library item, especially.
