    I've replaced a few seals on my VN22, standard sizes from mcmaster have worked fine
    so far but I haven't done that one. Unfortunately they didn't come out easily with a single tip seal puller...

    I picked up one cheap as well (Phase2 branded).

    The shafts seem to be hardened, but not hard enough
    to avoid being lightly scratched by the supports when you use it.

    Bigger shaft is 1.750"...

    I think that particular induma has been for sale for a long
    time. Maybe that would make for easier negotiation.

    There was also a member selling a pair of k&t’s in or around
    penn State, I think...

    Data centers are deploying solar. But it is a fairly complex problem, because data centers are usually designed to run reliably under all manner of conditions. So they would very rarely be only...

    VN22LU knee and column update

    Hi,

    I pulled the knee almost off today, enough to expose the back (mating surface to the column)
    to see the wear.

    First, the column face shows a lot of original scraping and a few scoring...

    You say "when the motor is switched on"... are you meaning the VFD is already in "run" mode and you have a switch between the VFD and the motor which you close and you're expecting the VFD to be able...
  7. cast iron rust inhibitor / paint prep for cold temps?

    Hi,

    I'm slowly working on my Van Norman 22LU, and currently it lives in an unheated garage
    in an NJ winter. I had finished needle scaling off all the paint, but didn't get
    it primed before...

    I also have a b&s 510 which came with a 1hp Dayton motor, non resilient mount, but with a vibration isolator pad sandwiched between the mounting plate and motor.

    It also had a 3ph 1hp GE with...

    I like many people I expect put a 1HP bridgeport J-head onto a VFD, probably similar to your motor. I wired the forward/stop/rev switch to the VFD controls, and then also installed a potentiometer...

    It isn't clear to me at least what order of operations you are using to run this machine.

    Is it:

    1) VFD starts as off
    2) attach drill 3ph plug to VFD while it is off
    3) power on VFD, but not...

    And you should not have any switching between the VFD
    and the motor, so what you describe for reversing on
    Tapping operations is a bad idea when 3phase comes
    from the VFD. You would either need a...

    E13 in my manual for WJ200 says unattended start protection is tripping.

    Meaning I think— you are powering up the VFD while run command (via control
    wires I assume) is already asserted?

    There are shims for the cast iron bearings for sale on eBay,
    If you are unsure of the right shim thickness (peel to the
    right thickness).

    I have an extra set, PM if you want them.

    Not really a question of "trying it" so much as you would need to rate the VFD for the Locked Rotor Amps of the motor. Which would be rather massive for that motor.

    Why not wire the low voltage...

    Hi,

    I just went and looked at the table screw assembly since it off my machine
    in the basement right now. Here is a picture of the casting on the left side
    of the table.

    I have a VN22LU which looks fairly similar to the VN26, and I took the table off recently.

    First step was removing the screw assembly. I removed the right side screw assembly but leaving the...
  21. Wanted: wedge & screw for SPG face mill

    Hi,

    I got a massive ~10" facemill cutter with 12 SPG532 inserts. It's an old
    SECO (marked Fagersta Sweden 257.1). Was on a NMTB50 with a VN22L.

    Unfortunately it is missing one wedge and...

    Mine is a 22L not a 26, so yours may differ. I found the same sludge in the cutterhead. I pulled it, cleaned it out, and soaked for a week in a bucket of diesel, spinning the spindle periodically,...
