Continuing the pattern set by American Lathe Builders and American Planer Shaper and Slotter Builders this is the first book to identify American builders of milling machines and the products they invented circa 1818 to the development of the modern milling machine circa 1920. Early versions of other American machine tools were largely copied from European especially British machines. The milling machine however was an American development. Built first for the firearms and sewing machine industries it proved to be much more productive than other methods and soon held a major place in all highproduction American machine shops. The book lists more than 300 makers and contains over 1400 illustrations taken from original catalogs and contemporary periodicals. These trace the development of the milling machine from a crude light weight machine to very large millers capable of machining parts the size of boxcars and weighing many tons. Attachments such as dividing heads vises etc. are also covered.
