Thanks John, I was wondering how that worked on the CVA. Quite simple really, like most good ideas. I wonder ...... :scratch: |

I ask because that spesific one is on my todo list.WHAYYYYY DOWN. Gerhard |

Gerhard, Here is a very rough C-o-C of how easily it could have been modded to allow both internal and external tools to be held, and the cam would operate in the forwards mode for external cutting and rearwards mode for internal. John |
| Gerhard Olivier:
Thanks John -That would work - would need to put positive stop forward as well as rear. And it would be a bit bigger to allow it to travel without play???? Hope I remember all this when I get back to the threading tools. Gerhard |

Gerhard, Unless you are doing very large threading work, 0.187" (4.8mm) would be more than ample movement. John |
