Subject: What is a good thin homemade cutting fluid

I just bought myself a couple of nice little 24v surgical pumps for
peanuts and am intending on using it to pump cutting fluid for my
lathe and mill.

Is there a good, thin cutting fluid that can be made at home? or do I
really need to buy some?

Any of you home chemists out there?

I'll be cutting mostly mild steel, tool steel and aluminum.

Thanks in advance

Frome The Machinist's Bedside Reader, pg 177, 47pt boiled water, 3pt
borax, 3pt soluble oil, 1pt tri-sodium phosphate.  The parts should be
mixed in the order listed.  Haven't tried it, anyone out there using it?
