    What you show on your level is much better than 0.0005".

    Isn't each mark on your level 0.0005" at 12"?

    Instead of using shims, why don't you use the holes and add some leveling feet?

    Something like this:

    Having contact with the ways is key for wipers to actually work. Without contact, it's just waving at the dirt and debris as it goes by.

    This question is analogous to saying, "I want to put...

    Sure, this kind of thing existed at one time. However, it was all proprietary information. Grizzly, the new owner of South Bend probably has (or had at one time) some of the info, but since they no...

    Now that I have looked closer (as close as I can), I can see two holes, so I think that you might be correct.

    He also looks like he gave it a "spray can" overhaul.

    If you get the lathe, get the regular gear for the end of the spindle and sell the one on it. They are fairly scarce, because when the...

    What you are looking at is a part of a hand lever collet closer (it is pressed onto the spindle at the rear).

    So, no large bore, just a standard 1-3/8" bore.

    How is the belt joined? If it is joined skewed, it's possible to get this bias. Also, does the pulley still have the crown? Is there movement in either pulley without tension on the belt? It...

    The spindle oiling system is one of the few non flow-through systems on your lathe. That means that oil is re-used, so you probably won't see the oil level drop that much. If your spindle caps...

    Not so. The "old" oil is at the bottom of the sump, while the "fresh" stuff is on the top. It is a non-circulating system, so all the old oil with all the settled out particles is in the sump. All...

    Even though it is marked "GREASE", I would still put in "OIL" (Type C), because the "GREASE" is no longer available and there are NO KNOWN SUBSTITUTES.

    What made you think that the GITS oilers were necessary? With all the South Bends out there from this era, many would have spindle damage from lack of lube if this was necessary. Even the newer...

    Wicks do become "clogged" which greatly reduces their ability to move the oil. South Bend used to recommend a total wick change every 10-15 years.

    That's not their purpose. They are there to break the surface tension of the oil film so that it continually flows from the spindle back to the sump. Apparently, if they aren't there, oil builds up...
