I used up the last of the cutting fluid next to the lathe. I didn’t know where the actual cutting fluid is stored. I used motor oil, but I know that’s far from ideal. But it was better then nothing for me. I also left a note under the bottle saying the same thing.
There is cutting fluid in the cabinet but its concentrate so the ratio is about 1-20 (1 gallon of concentrate to 20gallons water) so for those bottles you only put in a few tablespoons of that stuff and the rest you fill up with water.
someone filled it up already(hopefully properly because that stuff is not cheap)
