The generic for paraffin available locally in all Walmart stores.
It is ordinary mineral oil. Used by wood turners and fine
woodworkers. I use it on wood knife handles.
Also wood carvings.
Dries once absorbed. Easy to apply with cloth rag.

I would suggest that you remove the 3-jaw chuck and use a dead
center that has the same taper as your headstock (usually MT3 on
mini-lathes). Similarly on the tailstock (usually MT2).? You've
already shown that there is a misalignment with the chucks, but to
adjust the tailstock, I would use dead centers that fir the
tapers. Then adjust the tailstock accordingly.? Hopefully, the
headstock spindle is aligned with the ways.

Lubrication make the lathe and mill last for every.? here here i was a factory maintenence mechanic for 20 years the other thing i do for my lathe is keep a small fan over it it runs 24/7 365 my "shop" has no environmental controls bare steel will rust while i'm cutting oil will mix with the humidity and turn gummy

Re: to oil or not to oil, that is the question
For these small lathes, just about anything used for lubrication will suffice.? For example, some buy expensive way oil, but they could use just about anything.? The reason is that the forces, and in most cases the frequency of use, are rather trivial on a machine this size, and even more so for the average hobbyist who may seldom use it.? The goal of rust prevention is typically a larger issue.
On a larger lathe in an industrial 24-7 machining situation at high speeds, high forces, and trying to get every last bit of performance out of a machine, using proper products at proper intervals becomes very important.? But not really for these little machines.? Just to anything to keep the moving parts from getting bone dry, and keep the surfaces coated with something to prevent rust, and you'll be fine.

Re: to oil or not to oil, that is the question
Paraffin is found in canning.
Mineral oil is found in pharmacy?
I have both on my bench with other oils.
20w and 68w oil is automobile section
Cutting oil at hardware store
The only oil I can not found at local store is Way Lub.? I use on lathes since 1976?

Re: A Great Bit of Craftsman Machining
Never had a Real Bull, but have come to the conclusion they are better than SIEG (certainly with the SIEG's I have had).
Couple of things - Possibly not completely factual - they appear to use 4 bolts for the headstock, may induction harden the ways, rectangular (vs "H"") cross-slide, ball oilers.? ?Bed extension kits (see Amadeal) come fully drilled for easy installation.
The latter may (who can say) mean Real Bull has a jigged-up process to get all the lathe holes dimensionally correct on production lathes and kits.

Re: A Great Bit of Craftsman Machining
Lucky me. All oil fittings came on the lathe as new. Cross slide, tail stock and lead screw bushings. Thank you Real Bull

Arthur,
The spring ball oil fitting is installed only in the saddle casting , never in the ways. A small pilot hole for the oil port is drilled through the casting and then tapped the appropriate size. The ways get oiled when the pump oil can is seated squarely on the fitting and a squirt of oil is shot into the fitting.
The fittings can also be on bushings that require oiling.
Indispensable on many applications.

i'll surely get severely chastised for this blasphemy
my lathe has ball oiler at various locations
and i regularly oil the bearings and gear bushings
but not the ways and lead screw
I use way lub it made for bed ways and lead screws.?

??? ??? If it's out side to side ya move the tailstock in the
direction that gets it on point? ( no pun intended )?
??? ??? If it's out top to bottom ya need to shim? the tailstock
.
??? ??? That last pic looks to me like it was taken at a angle so
in that case ya may have to do both . Have ya checked to see id
teh headstock is on the bed straight & not tipped up , down or
sideways ? The mention of rods from a printer is a good one

Re: to oil or not to oil, that is the question
You could probably even just use a wax (some do that on their woodworking tools).? But a very THIN film of oil, which is all you need, is not really much of a chip magnet.
