    Patrick,
    I have a primitive power hacksaw which does not lift on the return stroke, and it never has. None the less, it works well...slow, but well. I don't have coolant either, though sometimes I...

    My SAG 14 has a 2-speed motor, the data plate says 5.5 Cv at 1450 rpm, 4 Cv at 722 rpm.

    Dolf,
    Are you sure about that? Usually the VFD's (single phase input type) are single phase 240 volt in, three phase 240 volt out. The VFD cannot increase the voltage. Then you have to configure the...

    Hi Joe,
    I checked my books and found that no Mikado's (2-8-2) were built in NZ, in fact there was only one ever used here, built by Baldwin in 1901 according to Wikipedia.

    I bought lots of Starrett gear when I was an apprentice in the late 1970's-early 1980's. All of it is made in Great Britain. The plant was (still is?) at Jedburgh, Scotland.

    Yes, it was the chuck I wanted. I am a great fan of Jacobs ball bearing drill chucks, so wanted to try this Japanese version. It has a J6 taper.

    The arbor was just a curiosity.

    Further to vancbiker's posts, I had a look for a P&W Tapemate Model C. It seems they are the same as (or made by) Fanuc Drillmate Series C.

    This guy has a few videos of the P&W machine, the...

    Poorly worded question perhaps - I would like to know what machine it was originally made for. The large bearing makes it fairly machine specific I am guessing.

  21. Arbor - can someone identify the machine it belongs to please?

    I bought a drill chuck recently; it was attached to this unidentified arbor.
    I wondered if someone could tell me what machine this would suit?
    The markings are "Fanuc" "Big" "30-J6".

    It might simply be the chuck jaws are bell mouthed, so allowing the shaft to bend and move.

    I doubt the chuck is loose or the spindle needs any attention. In fact I would strongly advise leaving...
