Watching Stefan Gotteswinter describe his recently acquired Weiler Primus lathe, he gets to a point where he shows the feed gearbox opened up (about 17:38), and he mentions that the gearbox is not oil filled, but instead uses a greased gears scheme rather than the gears running in an oil bath. The same machine does stay with full oil bath for the spindle drive, up to the point it uses a dual belt final drive to the spindle.
So for my old South Bends, they rely on the "total loss" oiling, as did many wartime era machines. Keep all the moving bits nicely oiled, then you know that all the oil you put in at the upper regions eventually ends up "down there " somewhere, and the arrangements to collect it up are kinda "non-existent". It relies on one being daily diligent, and looking after the cleaning and oiling with every use.
So to grease. We know hard chips and grindings and general dirt can stick in it, and not get carried away by moving oil, but if one could effectively "cover up and seal off" the routes where junk can get in onto the gears, is there any much downside to adopting grease as the gear lubricant?
