Restoring Antique Tools [EPUB ebook] 

Here is the book that finally unlocks the secrets that professional restorers have been using for years. It explains critical (and previously closely-held) restoration techniques in a way that even the most uninitiated can understand and follow, giving the reader confidence throughout and making the art of restoration not only extremely remunerative for the collector, but satisfying and fun as well. There are chapters covering all the categories of tools, as well as a general chapter on cleaning and refinishing. The author explains how to make a bow for a bow drill, how to tighten loose heads on Sheffield and Ultimatum braces, how to make wedges for planes, how to replace vials in levels, how to repair chipped or missing threads on a plow plane, and literally hundreds of other such invaluable instructions.
