Lathe oil ?

[RemingtonAI]

I run a 68 Heavy 10 so I use South Bend recommended A, B, C, and way oil. Most things take the Mobil DTE28, keeps the old machine happy. Jesse

Just who said anything about water soluble coolant? I pump OIL! Dark threading OIL on the tool room lathe (50-60% dark threading oil, 40%-50% Tap Magic). I keep a Golden Rod pump oil can full of the same stuff handy. Same stuff I wipe the ways off with. Never saw way oil until CNCs came into the shops. Yes Carlsbad, a bunch of you are using 'over kill' on about everything you do. You're trying to pull the wings off of mosquitos . Did you remove the wipers from the carriage? The way wipers do a pretty good job of wiping everything off, in including your way oil, if they're in good shape. A 'tramp oil skimmer' on a manual lathe, especially one that's not used for 'production' work? "Wanna-be" machinists, who've never worked in a machine shop.

Why in God's name would you ever remove the wipers from any machine tool???
Wipers do their job by keeping out debris from between crucial surfaces and keeping the way oil in there!!!!
