Universal cut knurling tool

Building a cut knurling tool was on my list for quite a while now. Cut knurling is a really interesting and satisfying process and especially for small machines as the Mini Lathe the better choice over form knurling. As the knurl is cut into the material instead of press formed, a lot less force is needed and much less strain is put on the machine spindle and the entire lathe. Paradoxically there is almost nothing to find about cut knurling and cut knurling tools used on small hobby machines here on YouTube. The tool I made is designed to cut both straight knurls and also cross knurls which is - as far as I know - a feature no commercial cut knurling tools have. For straight knurls the knurling wheel has to have angled teeth and the tool is tilted so that the teeth are horizontal to the workpiece. For cross knurling a knurling wheel with 90° teeth is needed and the knurling is done in two passes.
