Complete dimensions, diagrams, photos, materials list and plans for building a 50 lb. powerhammer are provided. Basic dimensions were take from the Little Giant 50 lb. power hammer. The power hammer discussed is of welded construction and is made mostly from material obtained from a scrap steelyard and surplus stores. Most material used is new but sold as surplus. It could take you three to four months of regular stops to the junk yard before your hammer will be turned on. The book is worth every penny!
