In this video, I show how I used the Whitworth three-plate method to turn scrap cast iron from a damaged milling machine column into high-quality lapping plates. The Whitworth method is a proven technique for producing flat, parallel surfaces, making it an ideal method for creating lapping plates. Special thanks go to Tom Lipton @oxtoolco for inspiring this project and for sharing his knowledge and expertise in the field of machining.
