    Many thanks guys. I know this is not the easiest way of making threads but I really don't want to hand tap 30 holes.

    Re: Thread milling

    Am I right in thinking that threadmills have a recommended diameter range that they should be used for. I imagine the clearance angles on these cutters are designed to cut threads little bigger...

    Re: Secondary Oiler

    Yes that is correct. If it were easy I would add a third oiler so each axes had its own feed. If I ever, god forbid have to remove the X axis table I would be tempted to change the connections to...

  17. Re: Anyone ever seen a R8 collet ground this way?

    Re: New R8 Collet

    That appears to be their view. I have since bought a UK made Crawford collet which is in spec and is identical to my original Tormach collet apart from the front face needing to be ground flat.
