Those of you who actually do metalwork what kind of coolant do you use? Have a self-contained system on my lathe and have been using a water based(Tri-cool?) and have not been happy with the rust that has formed in my tank. I lose a lot from evacuation and generally make up with water but I suspect that is the wrong way to handle things. When I added premix fluid, the fluid would gel up and not go back in solution. Just wondering what others recommend. I don't use coolant a lot but every time I need it my tank is empty. Suggestions? TIA

It provided AWFUL tool life and grew rancid in the sump in weeks. I don't use the coolant very often, so it tends to sit for a while. I then got some EnCool from Engineered Lubricants, and it provides MUCH better tool life, maybe 3X better, and NEVER goes rancid, even after months of sitting in the sump. Also, it seems to cause a lot less of the black stain on the table under the vise. (I still get some, but it wipes off with a paper towel.) Jon |

But, it filled the shop with a cloud bank, coating everything, and breathing the misty turned out to be a very bad idea. For a while, I used a 3M respirator with mist filters, and this mostly worked (the beard causes leakage), although I looked like a WW1 trench soldier during a gas attack. My wife found the grease-stained preying-mantis look very amusing. I stopped using the mister, and went to squirt-bottle cooling. Or brushed black sulfur oil as needed. I do such things as drill/mill/cut/bore things like railroad track material...so having a good oil based (or good water based coolant) is critical. Yes. I've been using a heavy soluble oil. I do get some black rust under things if I don't clean things up well enough. Joe Gwinn |

Actually the bottles original purpose was to spray olive oil for cooking. -- Best Regards: Baron. |
