Help! I cannot remember how to set up my lathe to turn a taper. Back in college I has to turn a 60° point on a plumb bob... Now I need to turn a .205" rod with a 45° taper down to a .045" pin that's .375" long. I remember it wasn't hard but not the setup. My search foo has been weak and I can't find out how to do it. :( Any help would be greatly appreciated! |

Rotate the compound to the desired angle and use the crank on the compound to the finished dim's. I am not sure what the part should look like, but I think the point is .045 dia. by 3/8" long at a 45 deg. on a .205 rod? Paul |

Hi Paul... Yep! Like this picture... except turned, not drawn in MS Paint, LOL! I guess my question is, which way do I rotate the compound? Mine is almost always set at 29.5 degrees for thread cutting (the handle is back and right). I'm thinking it needs to be on the back and left? Thanks! |

Can position top slide at any of the four 45 degree angles, makes no odds and depends what tool is going to be used. My top slides at 90 degrees for threading and normal turning. So if used top slide in position it is in now at 45 degrees you would have to reverse direction of spindle and cut on the rear. Usually easier to swing top slide around so on far side with tail stock out the way. |

Johnny said it, any 45 deg. angle will work and it depends on how you set it up. See which one works for you without hitting anything. Be careful running lathe in reverse with a screw on chuck as it will come off if thats the one way you pic if you have that type of chuck. Paul |
