Overview of this book

Until recently, Computer Numerical Control (CNC) machines belonged to the realm of heavy industry, but as technology becomes cheaper and smaller, these machines now can be used in home workshops. It’s not easy to get started, though, but thanks to this guide, you’ll be ready to take on a variety of projects in no time. A Tinkerer’s Guide to CNC Basics contains everything you need to get set up at home with computer-controlled machining and fabrication. Sparing you the theory, this project-laden guide helps you learn by doing. Once you’ve got to grips with the principles of CNC and installed the 3018 Pro CNC machine, you’ll gradually move from simple projects such as basic engraving to more complex milling and machining techniques. You’ll even learn how to upgrade your machine to accomplish more sophisticated designs. The plethora of projects in this book will keep you busy and give you the practice you need to get started with your computerized workshop. By the end of the book, your computerized home workshop will be one step closer to realization, and your machining skills will be taken to the next level.

Chapter 11: Building a More Capable CNC Machine

CNC lathe

I’ve always wanted to add a lathe to my shop. I have a mini-lathe that I use for machining light woods and plastics, but nothing that can handle larger, harder materials, and certainly nothing automated.

I recently came across a maker on YouTube called Melkano. While the videos Melkano posts are in French, each system he develops has a site in English and French that you can follow. The designs he has are very easy to understand. I have already built one of his early mini-laser cutters, using some scrap extrusions and a few miscellaneous parts. Melkano also has designs for a CNC machine (very similar to a 3018) and a 3D printer. However, what caught my eye was an automated lathe. Unlike all our other machines, the lathe has the workpiece turning at a high revolutions per minute (RPM) rate, while a sharp edge moves along one side and cuts into it. Just think about how the vertical supports of stair rails might be made.

Here is a video of Melkano’s lathe...
