    Update:

    The aftermarket brake pistons where I'd ground down the pins were junked, so before I trashed them, I scavenged the seals.
    Then in an exercise in sheer bloody minded curiosity, I cut the...

    I'm with the 'buy one on ebay' crowd.

    Think about it: if you screw up even a little, the accuracy of the Haimer is shot. And what's the point of having a Haimer if you can't trust it?
    Also: you...

    Well, I wish I'd checked this thread a week ago...

    Update:
    Ross is right: the center spike is the retractor.
    I found what had to have been the very last set of original, 50 year old Sumitomo...

    Update:
    Never bet against the house.

    In this case, it was a safe bet though.
    I didn't cut the pins, I just ground them down a few thou.

    Update:
    I pulled the brakes again, to work on them on the bench.
    Noticed that one piston was less retracted than the other, so I pulled that one apart.
    Here are some pictures of it in pieces.
    You...

    Greetings all,

    Yeah, the switch is on order. It'll take a couple of days to get here, but it wasn't any big deal. Just annoyed me.

    I'm a strong believer in the school of thought that says...

    Really? Please speak more of this.
    I know jack about cars.
    Give me a 100 year old machine tool I've never *seen* before, and I can have it humming before quitting time.
    Cars? Hopeless.

    It was...

    Update:

    It ain't the pushrod.

    I tried bleeding the brakes with a set of .030" shims stuck between the pads and the disk. Yanked them, pumped the brakes, and....
    Dragging.
    Again.

    Update:
    I thought I'd logic'd my way to an answer.
    I was wrong.
    I thought about it while I was driving home last night, and I came to the conclusion that I'd just been bleeding the brakes wrong....

    Well. That didn't work.

    I tried adding a bit of air. No dice. The dragging got a smidge worse.
    (I think. Hard to hear with the compressors and CNC's going.)

    So I pulled the pushrod, and...

    HI All,

    I'll try Joe's trick about adding a bit of air on Monday or Tuesday. Cheap and easy, can't hurt.
    If that fails, I'll yank the push rod and really get serious about comparing it with the...
  13. OK, thanks. That makes sense. It's getting...

    OK, thanks. That makes sense.

    It's getting plenty of fluid out of the tank. When I bled the brakes, it sucked down most of a whole reservoir's worth in about 6 pumps. So it's getting fluid.

  14. Mori MS-850. Not as silky smooth as a 10EE?

    HI guys,

    So I've got the brakes on the new (to me) Mori more-or-less sorted, got the DRO mostly installed, etc. Now it's time to get serious about actually using the damned thing.

    And I notice...
  15. HI Moonlight: I'm not sure I understand. The...

    HI Moonlight:
    I'm not sure I understand. The piston's got a spring loaded return. It was pressed up against the stock pushrod at rest, as issued. When I swapped the old one in, it presses against...

    More pix.
    Mostly the brake caliper showing how the pads come out.

    Update as I get ready to button the beast back up.
    The brake system is actually out of a 1965 Datsun Roadster. (Fairlady in Japan)
    The master cylinder and pistons are available as new manufacture...

    Mori MS-850 Center height?

    HI guys,

    On that Mori MS-850, where I'm rehabbing the brakes. (final details on that when the new brake pistons show up next week...)
    The original owner had really tricked it out. One of the...

    Greetings,
    I'm with most of the crowd here; you *must* be able to sight read the Gcode.
    You don't need to be able to write it, necessarily, but you *must* be able to error check for bad retract...

    Greetings all,

    I'm updating this thread in the hopes it's of some use to the next poor bastard down this road.

    Mori themselves are out of luck. The oldest manual they have in house in the US...
  21. 1978 Mori Seiki MS-850 brake caliper and master cylinder equivalents?

    HI Guys,

    So I've got a new-to-me '78 Mori MS-850.
    I'm doing the usual 'new toy' inspection, and the brake master cylinder seals have died.
    So I yanked the master cylinder, and now I'm trying to...

    In all the sturm und drang about the chair, I think we're all forgetting something: The knee jacking screw isn't the only thing holding the knee in place. All it does is hold the knee *up*. It...

    HI guys,

    I happened to run into the guy who bought the Bridgeport this afternoon.
    He's 230#, and says the chair works just fine for him. Damned convenient, apparently.
    He was on and off of it...

    I guess this is the point where I mention that yes, of course there's a tool post mounted skyhook for the Mori. I didn't bother mentioning it because I've seen that particular trick so many times...

    There were all kinds of guards of various sorts. They all got set to the side, and moved in a batch, by themselves, so it's hard to figure which ones went with what, but there may well have been one...
