Removal of stinky coolant

I believe your last position on foul coolant was it's not a problem because
you've proven it by putting a jar of it (presumably covered) on a shelf, and
it hasn't gone bad in a long time.
Now your exposed coolant in the open-to-air sump is turning foul. A typical
reaction could be: no ****.
For rust prevention, the most common and properly effective equipment is an
oil can, and at least one good eye. Manually oiling your machine gives you
the opportunity to inspect for cleanliness or problems as one puts oil on
various parts.
It sounds like you feel you don't need to oil your machine because you have
a coolant system on it.
Adjusting speed and feeds to appropriate ranges extends cutting tool life.
The use of a cutting tool lubricant (not coolant) extends cutting tool life
and dramatically improves surface finishes.
The reason there is coolant in a car's radiator is to prevent the engine
from overheating.
The reason coolant isn't used in the crankcase is because lubricants are far
better at reducing friction.
You often ask for advice/help with a situation, then you disregard most
points that are rational, and just add a lot of babble that you think is
going to convince anyone/someone that you know what you're talking about.
Maybe it would benefit you to spend more time concentrating on the lives of
strangers in Alaska. Possibly only a handful of others here in RCM weren't
already expecting these events to take place.
I must have missed something important, but getting great-to-excellent
surface finishes on leaded steel alloys hasn't been a problem for any more
than a few inexperienced or stubborn and misguided machine operators.
As I've suggested before, if you read and applied some of the excellent
machining advice that's available here in RCM on a regular basis, WRT feeds,
speeds, cutting tool geometry and cutting lubricants.. you probably wouldn't
experience poor machining performance on most materials you might work with,
or at least you would understand why the performance/finish isn't as good as
expected.
Excellent.
