My ok to polish the knives today as long not over 10 minutes. It also 98° in hobby shop at 10:30 today. This what used to polish the knives. Hope you put other uses for your mini lathe here for all to see.
 Still could not turn the plexiglass rod it take to long in 108° F day.? Dave

Cover the ways, no matter what temperature

Yes. Polish is abrasive and you don't want any getting on the ways.

The manufacturers found biggest wear to bed ways on lathes and Mills.? ?Is no lubrication.?
The manufacturers have putting automatic pumping oil but still the machinist can not fill the the oil tank or even look the oil gauge.?

I suspect that in the mini-lathe world, most get relatively light and intermittent use.? So low, that you probably couldn't wear the ways all that much during a lifetime oiled or not.? The greater risk is likely rust in the amateur machining world.
However, being really careless, like getting a lot of grinding dust all over everything, might certainly speed up wear.? But even then, I doubt if most would live long enough to see a problem.
In a professional environment with larger machines and near constant use, they are typically taken care of daily and "way oil" is used to protect ways and similar sliding surfaces. Way oil is special because it has a "tackifier" that helps it stay put (doesn't run off), even on vertical surfaces (rather handy for milling machines) and provides good lubrication to lower friction.? But for the mini-lathe, probably most any oil will do with the important thing being that at least something is put on the bare metal ways and other surfaces.
But if you want to use actual "way oil", you can get a small 12 oz. bottle from Grizzly that will probably last you a lifetime.

I agree?
The main lathe I owned and used for amost 30 years a 17" i purchased new. Keep well oil and no wear on any part of lathe.
The lathe did have a oil bath cross slide screw The only lathe new that had a oil bath.?
I gallon of way lubrication I use.
LMS has pints too

It this still true? ? ?The professional lathes I’ve seen all seem to be enclosed in a plexiglass enclosure and are pouring a flood of coolant on the part. ? ?How does this coolant interact with the lubrication? ? ? I know our little machines don’t have coolant systems but I’ve wondered how it works that a “fire hose” of what looks like water-based coolant would work if there were oil in the moving parts.

Such coolant is called "flood cooling."? It is water with emulsified oil and usually rust inhibitors.? Water conducts heat well, but oil does not.? Oil lubricates well, but water does not.? The most important lubrication is of the of the cutting tool edges to help prevent metal buildup on them.? You still clean such machines, but perhaps not as often.? There are a lot of CNC machines out there, true.? But also, still a lot of manual machines.? Many vendors of lathes sell manual versions from Griizzly on up.
There is also mist cooling which can be a good choice for smaller machines especially in a home shop.? (Flood cooling requires more such as the means to pump it, collect it, strain it, and recirculate it.)? The spray coolant is also water with oil.? And some of the cooling happens with the evaporation of water in the spray stream and after it lands.? However, it is more risky to leave this sitting on bare metal for a long time and it is best to clean the machine and normally re-oil surfaces when done.

For screw machines they a lubricating cutting.?
The only two problems with oil coolant is cost and it is not clean.

I hoping others post other uses for mini lathe .
I have it paints lines shafts.
Note use bedway covers I like plywood with cleats to hold in place
Winding coils.?
Please post your other uses

I've thought about using it for a magneto tester, but I haven't done it yet.

One many uses for lathe was line boring engines back around 1900 . Witch can still be done today .? Back 1900 they would make a jig to hold the casting on lathe carriage.?
Most lathes back in 1900 had tee slots for this work..?
Manufacturer would use lathe for almost everything in 1900.?
