Tim Your doing the right thing in cutting out some of the meat, to take some of the load off your small lathe, Try shaping the key out in small sections and you can always finish it off with a file, noting wrong in that its what our Grandfathers would have done. Good Luck Stew |

Hey Tim, as I said, I`m one step behind you, I wouldn`t know how to start without your post. It is really interesting as I showed the plans to my mate earlier this evening who does machining on a much bigger scale and he was immediately drawn and curious as to how the key way was cut. Following darrens linked post to his "one off key groove" - I can see how he has turned the parting tool on its side but I don`t understand how the groove is being cut? I take it the work piece is not rotating the in the jaws, but if it isn`t, how is the tool cutting? Chris |

You rack it backwards and forwards with the carriage, a bit of a poor mans shaper. JS. |

Chris --- End quote --- The lathe is stationary, the groove is (supposed) to be cut by the tool taking a tiny cut each pass. You know if you have a tool in the lathe and even when stationary you wind it past the workpiece it can leave a tiny groove if the tool's too close? It's the same principle with cutting a keyway. I'll have another try tomorrow and take some pics of my efforts. Tim |

Ohh, I see. So you are simply scraping metal off. Interesting. |
