Same stuff the pros use. Peanut oil, synthetic oils, water, and detergents.
It's as inexpensive to buy the packaged coolants as to buy the materials to make them.
Just plain water works, too. Just not as well. It has little lubricity.
Spring for a gallon of coolant concentrate. It makes a LOT, and for an amateur will last a long time. If you're a "low milage" user, consider a full-synthetic to reduce spoilage in the sump.

In Australia that would cost in excess of $50 I was just looking for something cheaper
$50 for a 25 year supply... Pretty affordable.
Water with borax, as in grocery store laundry supplies, work. The borax inhibits rusting - about 1 part per 100 of water by weight seems adequate.
1 part per thousand is inadequate.Hul

Has anyone tried the water pump lubricant sold at auto parts stores for people who don't run antifreeze and need the lubrication and corrosion protection? I've used Prestone brand in race cars, but never thought to try it as a soluble oil on a mill or lathe. Bout $6-8 a bottle that is supposed to treat 3-4 gallons of water in the radiator and engine, since you'll lose it pretty fast from evaporation and spattering I'd go at least twice that amount of water.

Only got ten years left and it is a waste leaving it to the offspring.
better to leave them 1/2 gallon of coolant concentrate than the $50 still in the bank.

A freelance custom machinist I knew just kept a can of Crisco handy.

When did Crisco become water-soluble?
