| The Artful Bodger tries to make something! |

| John Hill:
The Artful Bodger gets ready to try something scarey! I need to cut a slot in the end of that bar, the block of steel in the 4 jaw has a 'V' in it so the bar is securely located. I have ground a HSS tool to cut the slot and tomorrow, if I can pluck up the courage, I will cut the slot, I have 8 of these to do if it works out OK. Obviously I have to take really fine cuts but what is the recommendation, dead slow or a few hundred RPM for this type of interrupted cut? |

Oooooh, John! :jaw: That look seriously scarey to me. :bugeye: I wouldn`t dig straight in........ :scratch: Can you rough out the slot with a hacksaw, before turning? Can you rough out with a milling cutter in the chuck, & the component in the toolpost? Be very carefull....... Please! David. |

Yes John, certainly scary. It is not the plunge cut that will cause the problem, but the interrupted cuts. The lathe tool nose will take hell of a bashing. I am not saying you are wrong, as you have no other way of doing it, just take your time and get ready for anything that happens all of a sudden. It might go smooth as silk, and all our gum beating will be relegated to useless info. Give it a go, but win or lose, let us know how you get on. Don't be afraid of failure, and boast about your successes. John |

As Bogs said, just be extra cautious when you are doing this. Eric |

Hi John That looks like a brown trouser job. Don't stand in line with the spinning job, stand to one side and slowly does it. Good Luck and interested how you get on. Stew |
