"So I turned to old methods, and to
the masters, including Roy Underhill, who, in
addition to his fantastic videos, describes how to
make these tools in his book The Woodwright's Workbook.
Another important source is André Roubo’s Le
Menuisier Ébéniste, which was published in 1774 and has a
perfect description of these thread cutters, along with a
beautiful engraved illustration."
