Welcome back to my manual machine shop. In this video series I’ll be making a much improved knurling tool from my current bump knurler setup. Rather than engineer this one from scratch I’m starting with the sensitive knurling tool kit from Hemingway Kits (not sponsored). The kit is based on the somewhat renowned vintage “Marlco” design and has a lot of advantages and nice features. This first video will focus on the arm assembly and I’ll be making heavy use of the mill and the rotary table. And of course a fair bit of lathe work with some unique setups will be needed as well so you know I’m excited for that!
