Doolittle, Henry: - Henry Doolittle worked in the nuclear industry for forty-four years as a mechanical engineer. About twenty years ago he bought a small lathe and took up woodturning as a hobby. The lathe got him started in woodworking. About six years ago he picked up a CNC router and started making jigs and fixtures, which in turn led to his interest in using 3D printers in the craftsman's shop. Using the 3D printer, he has been able to print his own woodworking tools, a process which this book details. 3D Printers for Woodworkers is Doolittle's first book.
