    Naka Slant Jr. Tailstock Extension?

    On our Nakamura Slant Jr. cnc lathe, the hydraulic tailstock is threaded as in photo.

    Sometimes there’s no correct arbor screw for holding a face mill to an NMTB50 arbor and we use a SHCS and thick washer cut down to fit the hole in the face mill. See pic. Is this particularly dangerous or something everyone does? I found “real” arbor screws at Shars reasonably and ordered a...

    Special angle plate, why?

    I called Suburban Tool, whose Id plate was on the red angle plate, who said they had nothing to do with this modification. There’s a linear ball bearing with 1/2 inch bore screwed to the back. I have no idea why that was added. Maybe a common addition? Any ideas? Looks like someone wanted...
