Follow my journey leaning how to cut threads on the lathe. We look at four different approaches to screw cutting from easy to more advanced methods. We look at cutting not only right handed threads but also left handed threads, internal and external threads, measuring threads and cutting metric threads on an imperial lead screw and imperial threads on a metric lead screw. We also have a sneak peak at engraving metal with a fibre laser.
