This handbook, which explains in detail a variety of processes common to general metalworking, has been written by a number of thoroughly practical men, by whom it was contributed in another form to “Work,” the illustrated weekly journal of handicrafts and mechanics. Its appeal is to everybody who makes any attempt at working in metals, inasmuch as at least one of the processes—soldering, brazing or welding—will be met at a very early stage in the beginner’s experience. This handbook will be found a complete workshop guide to the usual methods of soldering and brazing, and will form an excellent introduction to the modern electrical and oxy-acetylene welding processes, to do complete justice to which, however, a separate handbook would, of course, be necessary. If readers encounter difficulty in any of the matters treated in this book, they have only to write to “Work,” in whose columns (but not by post) help will be willingly afforded.
