Today we're continuing work on the Hemingway Sensitive Knurler kit. I've had my eye on this knurling tool ever since I first got my lathe, and now I'm finally building it. This is one of the classic British toolmaking kits, and building from someone else's design will be a new experience for me. Today, we're making the eccentric cam, slotting the arms, and making all of the fiddly little parts needed to complete the tool.
