  • Clarification of Lubrication Terms

    I am hoping members can help my understanding of some finer points of lubrication.

    As I am in process of purchasing a "new for me lathe" that is fairly old, late 1930s, I got to thinking and some questions now seem kind of stupid [] but have lead to quite the reading load of some very specialized topics.

    I think I am beginning to have an understanding by reading such as this,
    but many terms are all relative and this is where I am getting bogged down, in the details.

    In many of the articles the terms "high speed" and "low speed" are used but only on occasion are actual numbers given to said speeds. One article stated it in RPMs and also implied it was only the shaft RPMs that were needed to determine "high" or "low" speed, other articles talk about surface feet per unit of time. How does one define more exactly what is "high speed" and "low speed"?
    Some articles talk of huge machinery, so does size matter? Or are the principles the same?

    As I've asked seemingly pointless questions before and will again, related to lubrication of the open gearing for my lathe, are there ways to improve the lubrication "system"?
    Gits (sp?) oilers are in many of the feed spots, do I consider installing some of the drip reservoirs I've seen on some lathes of that vintage, rather than hand oiling the change gears, does one consider some sort of a drip system for that?

    Thanks for input.

    That must a pretty big lathe you are considering.

    That article is talking about HUGE machinery.

    The principles are right, but you should get an article scaled to your equipment.
