Gerhard, I think you just came up with another use for the ball turning fixture. Putting a knurl on a ball. Neat idea. Nice project by the way. I need to make one of these some day. Bernd |

Gerhard Very nice handles for your knurling tool. I like the way you have knurled the round surface. Will make the knurling tool look very sharp. :ddb: :ddb: Cheers :beer: Don |

Thanks chaps Finally finished them- used some 20mmx10mm bar to cut t-piece to mount on the tool post. Then cut a test piece of all 3 the knurl patterns. I used 350 RPM (25mm bar) and a lot of wd40 sprayed onto the piece to flush away the bits - I cut small amounts and tighten a bit between each pass. When I stop the piece to check the pattern I leave the knurling tool engaged and If need then just restart the lathe. Others will have different ways but this works on my lathe. The only problem is the large straight knurl takes a lot of presure and I think it will be for Ali only it took a lot of passes before the pattern looked right. Gerhard |
