    Kitagawa has the rebuild kits. Not sure if you can buy direct, or have to go through a distributor.

    The return of the Nichols Mill

    You have enough room in that gap to use a two-piece adjustable gib system.

    The front gib is similar to what you have now, only about half as wide, with a slight taper along the back side. The...

    QT15 spindle motor pulley

    Are you sure there is no set-screw down between the pulley v’s?

    It seems the Japanese fastidiousness with press-fits has shown it’s ugly self!

    I replaced the rear bearing on the same spindle...

    Make sure there's not another setscrew under the one you've already removed.

    Those pulleys are a tight fight. Put more heat on it, should be able to pull it off with a good puller.

    Great reply!

    However, he will need to add an M10 or M11 on a line between the M5 and M31. The M10 is quill-only forward and reverse, while M11 is body-and-quill both forward and reverse.

    Seattle, Are You Still Alive?

    Help identify draw tube thread size

    Every CNC lathe I’ve seen has metric threads on the draw tube.

    Since you’re saying 16TPI, that would be a thread pitch of 1.5mm.

    The outside diameter should be an even metric size: 70mm, 75mm,...

    A trick to measure threads behind a shoulder is to measure the approximate pitch diameter with the thin points of calipers.

    Why the 3" spindle bore requirement? That is going to put you in a much higher price-range for used.
