Apron:
SCH 630 (I think this is a hypoid gear oil)


Clausing suggested DTE 26 here, but I bet hypoid oil will work just
fine, although it's far thicker than DTE 26.

Apron? I was thinking the gearbox under the apron. For the apron,
Clausing suggests Vactra #2 for the oil points that feed the ways on the
apron.

Well, it's just semantics, but technically the carriage is what rides on
the ways, which are oiled with way oil via the little brass fittings
with the check balls (what I always called 'Gits' fittings, maybe there
is a more proper term). The apron is generally the gearbox on the front
of the carriage with the controls, gearing and clutches for engaging the
long and cross feeds, also the half nuts for cutting screw threads. The
carriage also supports the cross slide, which in turn supports the
compound slide (in machines so equipped).

Yeah. After my posting, I found in my 5914 manual that Clausing calls
the part riding on the bed ways the saddle, and the part hanging down in
front and full of gears the apron. So, we are aligned.


I just noticed what I called SCH 630 should actually be SHC, oops.

OK. No wonder I didn't find it.

Someone else suggested McMaster-Carr as a source of lubricants.


I don't know the history of your lathe, but mine was made in 1972, and
was used in industry for 36 years before falling on hard times and
ending up in a home shop, where the lathe will not get much added use or
wear compared to what it already has accumulated. I bet that any oil of
approximately correct viscosity that doesn't chemically attack anything
in the lathe will do just fine. And any oil is better than no oil.

Mine is 1967 vintage, if I remember correctly. I agree with your view
that the amount of use these machines are now subject to allows one to
be somewhat looser with lubricant selection, but not lubricant application

So I can hope that my lathe is the less worn of the two.
