VIDEOS:
Dan Gelbert has an amazing 18-part video series "Making Prototypes" that covers a number of machining and fabrication skills. Our powder coating was originally inspired by these videos! https://youtu.be/xMP_AfiNlX4?si=8c5uqhQTjO-DNqhV
Fans of Mythbusters will enjoy Adam Savage's "Tested" channel. Recently he's gotten into precision machining (lathe, mill, even a pantograph milling machine). Adam served for a while on the Nation of Makers (a national makerspace organization) board of directors.
Magazines:
Village Press (up in Traverse City) publishes Home Shop Machinist and Machnist's Workshop, bi-monthly publications that focus on machining projects and techniques. They used to also publish Digital Machinist, which focused on CNC.
