I have a Craftsman 101.07403 12x24 lathe.

I've been told to use 20-weight NON-detergent oil for the spindle, but that has not been easy to find, especially non-detergent.

How important is it that it be that specific weight; can it be thicker or thinner? Can it be a mixed-weight oil, for example 10W-30?

What about the detergent issue? What will the detergent do to the lathe over time? I've heard it's just for cars with high heat differentials and for moisture control (not sure of all the technical stuff, but let's just go with that!)

Thanks!

As I understand it, the motor oils have detergents added so that any small trash is kept suspended until it can get to the filter where it is trapped for removal, unlike the spindle oils which let the trash drop out. For my South Bend 9 as well as my milling machine I have been using Mobile oil from MSC spindle oil and way oil in one gallon containers and it works well for me== Jack

Use the Mobil Vactra way oil for your lathe mechanicals. If you try 20-wt spindle oil, it will end up draining out the back of your headstock and out of the bearings and onto your chuck, where it will be slung in a perfect tangential pattern on your walls, ceiling, and the front of whatever you are wearing. These open-bearing designs require a tacky oil (way oil) to stay where it needs to while you are running your lathe. Everybody with an Atlas lathe uses Vactra, and that's no coincidence.

Simply use ISO 68 oil. Northern Tools sells it in 12 oz containers. I went to my lubrication seller(local) and asked for ISO 68 and he came out with a 4 gallon pail for $39,00. Done and now I have a lifetime supply. I understand Blains Farm and Fleet sell ISO 68. Look around, it there.

Three are 4 grades. LMS sells Mobile vactra #2. I assume that's the correct one? I can use it for the ways and also for the spindle?

Harbor Freight used to sell SAE 20 non detergent in a 5 quart bottle for about $20. Someone said it was no longer carried, but might be worth a look.

Vactra #2 is the right one. Your machine will love you for it. You'll want a half pint pump type oil can with a rigid nozzle to go with that.

Do not use Way Oil for the spindle bearings or in fact anywhere other that on the ways and dovetails. It will never get through the felts in the oil cups and the bearings will always run dry. You should never run the machine with the belt cover raised. On the Timken equipped machines, the oil will not drip out of the front of the front bearing. Any other drips that are slung off will be caught by either the belt cover or the gear cover.

High Detergent oil is designed to scavenge moisture from inside an engine as it cools off. When the engine is running, it goes out the exhaust as the engine warms up. Hopefully, your lathe will never get that hot. But it will scavenge moisture as your shop cools off at night and promote rust inside.

You cannot mix SAE 10 and SAE 30 to get SAE 20. What you will get will start off as a mixture of 10 weight and 30 weight molecules. The 10 weight will drip out faster than the 30 and you will soon enough have only 30 left. SAE 20 is equivalent to ISO 68. Either will work OK.

Not necessarily. Fluids move through felt due to the physical principle of capillarity, which is a function of surface tension and capillary channel cross-sectional area. Vactra #2 has a much higher surface tension than ISO 68, therefore it has a stronger capillary action through felt. I use Vactra #2, and I make my own felts from wool felt stock. They work great. Caveat is that I run a babbitt head because I like it better than my Timken head.

They didn't have it in their website. I called a local store and they do not carry it.

I'm very sorry - I meant Tractor Supply, not Harbor Freight. :oops:

But I just checked the Tractor Supply website - they don't list it. I purchased some from them about 2 years ago.

Someone on I think the A-C Group on groups.io reported that last time that he looked for it at Tractor Supply he found a couple of gallons on the store's Clearance table. SAE 20 crosses roughly to ISO 68. I've been using Moble Heavy Medium Circulating Oil ISO 68 for several years.

I buy non-detergent #20 oil from O'Reillys for my air compressor. Use it on my lathe also. It runs about $10/ gallon, you need to go to the website and find it and order it online and pick it up.

That is good to know. I used to buy SAE 20 from the auto parts store that's now O'Reillys but they quit carrying it. Could you post the pertinent URL?

If I remember when I get home, I'll check the container to make sure of the brand.

AW,(anti-wear),hydraulic oil in all sorts of weights is available everywhere in the world. Basically any hydraulic oil will do as hydraulic machinery uses plain, roller, taper bearings, vanes and gears in pumps and gears in gearboxes. If you live in any center of civilisation some nearby sells hydraulic oil.
DO NOT use an automotive multi-viscosity oil as it is designed for totally different operating conditions. The weight you use can vary depending on the local temperature.
Look up lubrication in your local telephone book and find a company near you and ask questions I think you will be very happy with the help you recieve.
Here's a bit of info on a flyer from one company and there is a wealth of information available online from all oil companies. There are also crossover rating charts online: https://www.engineeringtoolbox.com/iso-grade-oil-d_1207.html

I recently bought a gallon of AW46 at O'Reilleys for around $16. Had it in stock on the shelf. I am using it for everything on my Craftsman 12 x 36 lathe. Since I don't use my lathe every day I give everything a quick shot of lube every time I use the lathe regardless of whether it is a daily, weekly or whatever recommended lube interval.

Looks like you use this:
https://www.oreillyauto.com/detail/b/o-reilly-oil-4527/chemicals---fluids-16461/grease---lube-16582/hydraulic-fluid-17707/4835179abd07/o-reilly-oil-1-gallon-conventional-hydraulic-fluid/74405/4601123?q=hydraulic+oil&pos=4

It's a bit thinner; does it fly off the machine, or is that not even an issue?

I live near LMS, so I bought some Mobil Vactra oil from them. I also got some Lubriplate. I'll try the SAE 20/ISO 68 oil and see what happens.

After having gone through all the same as the OP I gave up and went this way, I have no affiliation to this source.

Cheap, expensive I don't know. Is it the right oil? Well I hope so but it is what I am using. Came bottled up nicely.

FYI, I used 20W no detergent/ISO 68 which can also be called Indol on my headstock. It flung it all over the place when it was running and pretty much dripped out when it wasn't running.

jsh,

If you put oil of almost any reasonable viscosity on the gear teeth, of course it slung off immediately. You are supposed to use a fairly high melting point grease on the gear teeth.

I use grease on open gears, my bad reference I guess but I meant bearings.

OK. Thanks. I'm running low on SAE 20 (or actually ISO 68) so I ordered a gallon.

Oops, I ordered a gallon of SAE 30. How did you manage to find SAE 20. All that I can get their site to show me are multi-viscosity HD motor oils.

You changed "headstock" to "bearings". But first, you aren't supposed to run the lathe with the belt cover open (if it has one). second, if there was enough oil to sling all over, there was too much oil. Third, there should be low density felt plugs in the two oil cups for the spindle bearings. And fourth, the Altas lathe's lubrication system is a total loss one. So it's kinda like the joke about how do you tell that a Land Rover is out of oil. Answer - no fresh oil spot on the drive way. Anyway, that's why you are supposed to give it a lube job once a day or before using. Except the spindle cone pulley and back gears are Monthly or before every usage of back gears.

I've used the felt cord from McMaster Carr for wicking oil from the bearing oil cups on the headstock of my Atlas/Craftsman:

I think I used 3/16" diameter firm felt.
