Atlas 10F lube chart.
- So the Atlas 10F lube chart is great. I love manuals, and I tend to try my best to operate and maintain things according to manufacture's specs. That being said, it's obvious that some things may call for alternatives as this manual was written many years ago. Which brings me to my question(s). The lube chart calls for S.A.E 10 motor oil. Forgive me if this is an ignorant question, but does that even exist now? I've checked at all the local auto supply stores and keep getting funny looks.
What lubes do you guys use for your lathes and what lubes for which parts? I know I want a non detergent oil. I can find S.A.E 30 non detergent, but that seems way too thick, especially when it's colder.
Does anyone bother greasing the back gears and or the change gears? I understand the issues of grease collecting dirt and causing more harm than good and have heard many conflicting opinions about this topic in general (to grease the part or not to grease it) The lube chart calls for Keystone No. 122 heavy outer gear lubricant, is there an alternative to this grease that is readily available locally in most cities, and is it worthwhile to grease the gears?
I greased my countershaft bearings with red n' tacky. I'm just a fan of the stuff, seems to have always served me well.
Also, on the lube chart, it calls for a mixture of white lead and oil for the tail stock center lubricant. Firstly, I can not understand (without taking my tailstock apart) how the lube would reach the tailstock center from where you are supposed to put the lube. Is this just a reservoir that you would dip or somehow apply the lube to the point of the center with? If so, I believe I am missing the cup, because all I have is a hole where it says there should be a "cup".
I am interested to hear what you all have to say through your experiences on this topic.
Thanks for your time.
See my previous on the subject of viscosity. Atlas, later changed name to Clausing, has recommended SAE 20 for about the past 60+ years, not SAE 10.
The reason for not using high detergent motor oils has nothing to do with sumps or recirculation. HD oils are hygroscopic (they scavenge or absorb water.). This is either no problem or good in an IC engine running at temperatures around 170-180 deg. F as the water eventually goes out the tailpipe. But in environments with high relative humidity and relatively large temperature excursions, it causes rust on unpainted surfaces.

FWIW I found SAE 10 oil on the shelf at Tractor Supply (see link below)
Looking at the design of the Atlas lathes, I don't see much that can go wrong related to oils. The worry over detergent oils, I honestly don't see it in relation to the common Atlas lathes. I hear people saying a detergent oil will cause deposits of old metal shavings to be recirculated into gears and bearings, but that doesn't make any sense at all considering the design of the Atlas lathes. I could see where that could happen with lathes that actually have a sump full of oil, but my TH42 doesn't have a sump for re-circulation, and I don't think other Atlas lathes do either (experts, chime in here and correct me if I'm wrong).
The nature of oil, I mean why we use oil instead of a grease is the "washing" property of soaking, but then running off. It cools, lubricates, and cleans all in one. Oil will take deposits of dust or fine metal shavings and flow such debris away from the working parts; again, that's why we use oil instead of grease. In places where we don't need that action of carrying debris away from the working parts, we often use grease.
My TH42 has Timkin bearings and an oil cup. The oil is wicked from the cup into the bearings and eventually runs out, there's no pooling going on, nor is there any place where oil is recirculated through the bearings. So the oil is essentially one use. Therefore you should be able to use most any off the shelf motor oil and be just fine.
If there wasn't a Tractor Supply close by with the SAE 10 readily available, or MSC Direct just up the road and I was in a pinch, then I'd just get something like a 5w-30 and call it good.
You have to remember, the manual recommends SAE 10 because there wasn't a great deal of oils to choose from when they first made the manual. As the years went by, they never bothered to change or upgrade the oil recommendation because SAE 10 did a great job. SAE 10 is thick and viscus and does a good job of lubricating and preserving. Furthermore a non-detergent oil recommendation is consistent with, and safe to use with most all machinery.
Any oil is better than no oil. I will always recommend what the manufacturer recommends, and if it's readily available then there's no reason not to. But if you're in a pinch and you have the choice of no oil, or using common motor oil, then use the common motor oil and don't lose any sleep.
Just my .02 on the matter.
