case of the cross slide.

Any ideas on what grade of oil I should use?

Also any recommendations for good instructional books for someone who
has a fair idea but needs a lot of practise and advice on metal
turning - eg types of steel, getting a clean finish (that I know the
lathe is well capable of), cutting threads etc etc etc.... you guys
know the drill!!!!


My Sheldon lathe has 4 different oils in 4 gearboxes! There's the motor
gearbox, headstock, QC and carriage. The carriage, crossslide, apron gears
and nearby parts are lubed by a pretty typical way lube, as the slideways
and leadscrew nuts are the most important surfaces to protect. Given a good
way oil, and running at the low speeds the other parts get, they will do
fine.

A bit unusual to have a true pressure-lubed gearbox, unless it has
hydraulically
shifted gears. My Sheldon has a faily light gearbox lube in the motor
gearbox,
and a different (lighter, I think) oil in the headstock. Maybe they want to
use the lightest oil possible in the headstock to reduce heating.
Anyway, the
headstock is splash-lubed by the bull gear, which churns oil up to a gallery
that spills oil on specific locations. the motor gearbox is pretty much
immersed in the gear lube.

I can get the specific lubricant types for you, if that would be
helpful. I found
a local outfit that repackages industrial lubes from the drums in 5 Gal
sizes, and
they were able to cross reference all the old lubes called out for my
machine.

Jon,
I just picked up a Sheldon Lathe, and I have the book coming. Can you tell me what oil you use and where you use it. I just ordered Vactra #2 Mobil Way Oil and DTE Heavy Mobil DTE circulating oil. I was told by another sheldon owner, this was all I need. Could you please help me out?
Regards
ADAM

Is this a Sheldon R-series? That is quite different from their other
lathes, a VERY high-end toolroom machine.

Anyway, there is actually an error in the book and lube plate on machines
made over a couple year range. They say to put Vactra in the headstock --
WRONG! They MEANT to say put Velocite in the headstock. So, I have put
Velocite #6 in there, but it is supposed to be Velocite heavy. (Velocite #6
is for the high speed spindle, so I figure it is OK for light use of the
lathe.)

The motor gearbox uses Mobilube EP80-90

The apron and QC box call for Mobil AA, which my lube supplier substituted
Mobilgear 626.
