Last year I bought some different cut knurling wheels for my mini lathe. The original holders for the wheels are very expensive, so I made my own one. Now I 'm able to knurl in any angle I want (if I have the right wheels ;) ). Straight, fishbone and also 45 degree cross knurling.
Many thanks to www.baer.tools for their extrem drill sets:
