EMC2 Threading
This is a nice slow example of single point threading I found on YouTube (it's not mine!). In this example a full-form tool is being used (ie. a tool with a flat nose) to make an ACME or trapezoidal thread (not possible to tell the difference without measuring, and sometimes difficult even then). ACME and Trapezoidal threads can also be made by true single point threading, without needing a full-form tool.
