Okay, I get about the best finish with stainless and alloy steel on the
lathe with oil. The 14x40 (and the turret lathe) has a coolant pump,
but a single drop of oil goes much further without soaking me down.
There are oil drippers available, but they are either pretty crummy like
the one I lost a decade or more ago that came with my Harbor Freight
drill press, or they are very incomplete for the application.
I think one of the issues with the cheap ones is they don't have a hole
in the bottom (top) to let air in. It makes it very hard to get a nice >controlled drip.
For lathe work my thought is it needs to be on an articulating arm that
can be mounted to the back splash or on a mag base. It needs to be able
to be visually checked for volume. It needs a valve at both ends. One
to control inflow of air, and one to be able to adjust to as slow as one
drip every 3-5 seconds.
I don't know where I am going with this, but aerosolizing cutting oil is
not the answer I want. I just want a nice slow drip of oil. I'm
actually thinking two valves at the bottom. A ball valve to turn it on
and off, and a needle valve to control flow when its on. So it can be >adjusted and left adjusted.
Varying head pressure might be an issue. I guess it would need to be
kept pretty full. Hence its volume needs to be easily checked at a
glance.
I'm about decided I'll have to make one, but I'm open to being surprised
with an economical and elegant solution.

Or look for an antique bearing drip oiler. https://www.ebay.com/itm/405049422883?
The cam lever above the knurled adjuster is the shutoff, the crosswise
hole lets you see and control the drops before they disappear into a
bearing.
The simple way to maintain the level in a reservoir is to feed it from
an upside down bottle with its opening at the desired level. When the
level drops air will enter and let liquid out to restore it. I haven't
found an on/off valve with water bottle threads, I might see if this
will reshape water bottle threads to fit in-line hose ball valves. The
two are almost identical. https://www.amazon.com/MILMUMU-Outdoor-Cleaner-Household-Cleaning/dp/ B0D37J2YPD/ref=sr_1_13_sspa?
The ancients used this principle for their water clocks, and the hourly siphon-drained water to operate dancing figures and whistling cuckoos.

He described a vessel that appears to convert water into wine, by
opening or covering the vents of secret compartments with a finger. I
heard of that somewhere else too.

How about a can of oil up on a shelf with a hose down to a needle
valve assembly on the carriage, with a 1/8" copper drip tube that is
hand bent as needed. This is almost what I do.
What I do is to replace the can on the shelf with a strained-pump
assembly on the floor running soluble oil to the needle-valve
assembly, and the chip pan draining back into the coolant filter-pump.

Oil can on a shelf is as good of an idea as any. Not sure if being on a >shelf up high (there is one above that lathe) will add much pressure
over right there on the machine. I would think the majority of the head >pressure if from weight rather than height. Can't hurt though I suppose.

The pressure at the bottom depends only on height and density. The
amount of fluid anywhere in the system has no effect.
