| Internal threading. 35mm x 1.5 on a 7x10 |

Fortunately the depth isn't that great. Maybe 15mm tops. Now to find or grind an internal thread tool! Eric |

A small boring bar makes a good holder for a short threading tool bit. Joe |

I do not think there has to be an error, I know it is possible to cut perfect inch threads with a metric lead screw provided you have the required compound 120/127 change wheel so I presume there is a way to go the other direction? :scratch: |

Eric, Are you sure your little lathe is in fact completely imperial? A lot of the far eastern machines are in fact metric, 'made' to cut and work in imperial. Like John above, we both have metric lathes, but they can cut perfect imperial with just a gear change. On the smaller lathes, they usually use a 63 or 64 gear to make it cut 'almost' imperial. Have you such a gear size in your train? If so then it is in fact a metric machine, and with the correct gears in there, will turn perfect metric. John |
