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

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

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

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.

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

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 know? 7" and 8" mini lathes have seen? spindle hole just over ?" . I can even find larger
Do some mini lathes have smaller spindle hole?

That is a small hole. I can see why you want a bigger hole.? The on the chart for a 3" is only 0.63"? I just a 5" 4 jaw on my lathe it set up for a 4" chuck.? Need backing plate purchased? one from little machine shop.com I purchased the from Amazon.??  Dave?

Sounds great.
Most almost same model of chuck 3 or 4 inch?
I will miss fun 4 jaw chuck and bars. It more taking on off chucks it time to do right.?

True.? People have pushed the 7x lathe quite far.? Consider that the Grizzly and PM 10x22/30 lathes have only a 1" spindle bore.? And I definitely want one of those as well.

You use 4jaw chuck? I have 5" [125mm] has good size hole. It has 1?" 30mm size
