Making A Knurling Tool For The Lathe

G'day everyone,

Fore the last project of the year I thought I might as well get around to doing a project that has been on my list for quite some time. And that is to make a new knurling tool. My old one is a bump style (or push type) knurler and whilst they are great for larger lathes, they do require quite a lot of force to use, and according to the machining zeitgeist, that is very bad for the spindle bearings.

The new style that I will make is a clamp style. It will use a screw to clamp the two pattern wheels on to the workpiece, which should save the spindle bearings. This seems to be quite similar to a scissor type knurl tool and I have no idea if there is an advantage to one type. All I know is the clamp style works and it works well. I hope you enjoy the video
