    Wow thanks! I had tried to order from Motion Industries and they said it was made to order
    with minimum quantity of 15. Seems like BDI has stock. I've ordered a few, we'll see if they have them....

    I tried that. Garlock says “we haven’t made that in decades but is replaced by 63x0005”

    SKF lists another part as equivalent, which McMaster has as 5154T47.

    This is a plunger. You push the “button” which is spring loaded, inside the casting the plunger pushes a measure of oil into the bearing. Whole plunger is in oil normally, so if the seal isn’t a...

    The supply of oil to this part of the machine really is poorly designed IMHO.

    A single bijur metered oil line drips from the upper saddle through the casting,
    and onto the top of the lower...

    One other question-

    I will fill the oil grooves with epoxy in applying the turcite and then recreate them on the turcite surface... this is straightforward.

    However as you see from the picture...

    turcite thickness / compression

    Hi,
    working on a VN22LU saddle. The lower sub-saddle of the universal rides on the
    knee top surface dovetail.

    The casting itself has worn due to chips and lack of lubrication, and is about...
  7. Looking for Oil Seal for VN Arbor Support lubrication pump

    Hi,

    Have a 60+ year old VN 22LU arbor support, which has an integral push button
    oil pump from a reservoir. The push button is sealed with an oil seal.

    The original seal was a Garlock,...

    Are the shell mill holders NMTB50 or are they also for the Weldon quick change system?

    Thanks all. I was concerned that I was missing something in not
    correcting the alignment. This discussion has helped to understand.

    I went back to the Schlesinger book and it too mentions these...

    Perhaps that is the conclusion then? That if the pivot points are aligned, I can center the cutter
    with the table at 90degrees, and then I could swing the angle arbitrarily and the cutter would...

    Connelly Section 27.75 gives a brief description:


    We will now take up the subject of offset of pivot axis as promised in an earlier paragraph. The situation briefly is this:

    Yes, I mean the center slot would be parallel to
    But offset to the rear of the table X movement.

    I believe this would introduce some error in
    Features milled with the table set at an angle
    And...
  13. Scraping saddle on universal milló t-slot alignment

    Hi,
    Iím (still) working on a VN22LU universal mill.

    I had about .007Ē wear on the saddle ways mating the table,
    Mostly as you would expect at the ends and less in the center.

    There is also...

    As has been pointed out recently in another thread,
    If you plan to do power tapping you might want a VFD
    That has enough braking resistance to stop the spindle
    And reverse quickly. Not sure how...

    You'll be happy to hear that Troyke 15" was sold and wasn't on that machine the last time I saw it.
    However I suspect it had been on there for 15-20 years, as the owner used it for one operation...

    Sure, agreed. I guess what I mean more precisely is whether the deceleration capability of these drives is enough (given the relatively low spinning mass of a J-head mill) to reverse quickly enough...

    I'm using two 2HP Hitachi WJ200's for my mill (Van Norman 22LU). They were $275 each at Drives Warehouse. The Hitachi are quality units.

    Why would you want/need a braking resistor for a VFD? I...

    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

    penn State, I think...

    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...
