DIY Precision Lapping Plates from Scrap

In this video, I show how I used the Whitworth threeplate method to turn scrap cast iron from a damaged milling machine column into highquality 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.
