The metal lathe needs transmission oil for the ways.
There’s an orange dispenser can marked “Way Oil” in the machine shop area. If it’s running low, look in the yellow flammables cabinet (near 3D printers) for a bottle of automatic transmission fluid. It might also be in the larger metal cabinet in the blacksmithing area.
Okay. I’ll look around some more.

Possibly it’s near the small lathe.
