While this publication is not a how-to-weld manual, it does contain information on where to obtain such literature. Its aim is to give newcomers to the field of amateur aircraft construction a broad and valuable insight on what steel tubing is all about, to help them work their way safely and productively into this specialized skill. There are many rare illustrations of both technical and historical interest and this makes the book a "good read" for those who are interested in the history of aircraft construction. It also comprises a readable and valuable refresher course for A&P mechanics who have become out of touch with the art of aircraft welding. 36 pages.
