| When is half of 60 not half of 60 ? |

The tool is at 90 degrees David. Any movement of the cross slide inwards from the last cut will cut both flanks. There are advantages and disadvantages to setting over the compound slide and not setting it over. In the end you pays yer money and takes yer choice. |

Yes, I just woke up and realised the big mistake. Please ignore my last response. Sorry all. Dave. Now I can go back to sleep. :Doh: |

If you did your last cut 'straight in' (to clean up) then you would finish up with a thread that had one face at 31 degree and one face at 29 degree. Does any one else agree with that ?

I have yet to try screw cutting in the lathe, this is all very interesting and useful thanks :) |
| DavidA:
Funny thing is that , in reply #5, I accknowledged that due to the tip being set square to the job and the last cut being 'straight in', that the correct form would be produced. So I don't know why I had that lapse of logic. I was just dozing off when it hit me 'Oh (expletive deleted) Must change that before they notice.' Too late. Phil. Looks as if our posts crossed. Nice sketch though. Thanks for that. Dave Showing signs of ageing. |
