Hello, I want to turn down a section of a lead screw in the lathe but I`m concerned about damaging it in the chuck jaws? Should I be concerned about this? I`m guessing it is steel so shouldn`t mark and the threads are quite chunky but I just wanted to make sure as I can`t afford to ruin it. Chris |

Shove a slice of drinks can beteween the L/Screw & jaws ... :thumbup: Soft Ally usually. BC |
| BillTodd:
Just insert a small piece of copper or aluminium between the 4 jaws . If you are using a 3 jaw: wrap a thick-ish piece of ally around a similar sized bar, grip that in your chuck (space the gap appropriately) then bore it to a close fit to the lead-screw - don't remove it from the chuck or mark its position well, before inserting the lead-screw Bill |

You don't say what kind of leadscrew you're machining. If there's any significant length extending out of the back of the lathe spindle, only carry out machining at low RPM (backgear) or you'll get a bad case of 'whip'. Sorry if I'm stating the obvious. Joe |

The ones I did for a router, I simply chucked them up in a 5C collet. This will grip it tightly and leave no marks. :clap: When I did some really hard ball screws for my mill/drill, didn't have the 5C so used the 4 jaw with no extra protection. Those things are HARD :bang: |
