Welcome back to my manual machine shop for the finale of the knurling tool build. I’m building this mechanical project from the somewhat famous Hemingway Kit (not sponsored) that is modeled after the old “Marlco” design. While last time there was a lot of mill work on the rotary table, this time there is still a lot of mill work, but with the collet block instead. Plus lots of quality time on the metal lathe. And maybe a visit or two to the box of shame. In other words, a well rounded project. In the end I make it through with a nice replica of a vintage tool capable of making both straight knurls and diamond knurls.
