My Clausing has a flood coolant system. Which actually works, except
the switch for it does not work. I will fix it, but the pump is
working great. I have cleaned up the system somewhat and it is running
smoothly. For coolant, I used a water soluble oil from McMaster that I
diluted about 40:1. This oil is not so bad, as I kept a jar of it
diluted for about half a year, and it did not separate and did not
stink.

My question is, would occasional use of this coolant rust the lathe.

Not likely, if the coolant contains rust inhibitors as most do and you
have mixed it properly.

I repair machinery for a living, and find that rust problems develop
when the employees dump 5 gallons of water in the tank when it gets
low..again and again without using a proper refractometer to check the
water/coolant mix. Pretty soon they are running water with a slight blue
tint.

You will be fine.

The more you present a leftist with factual evidence
that is counter to his preconceived world view and the
more difficult it becomes for him to refute it without
losing face the chance of him calling you a racist, bigot,
