| What oil to use for gearboxes and headstock on the Edgwick lathe |
| (1/3) > >> |
| Edgwick one:
Someone suggested hydraulic oil. I thought something like gearbox or diff oil may be better Any ideas would be most welcome |
| mechman48:
FWIW; I would use gearbox oil, it has different additives than hydraulic oil; pressure additives, antifoaming additives, higher viscosity etc, check out the chemical constituents from the MSDS data sheets for better info. I use car gearbox oil from my local Halfords auto store (usual disclaimer) on my lathe. Some members would offer more informed opinions, but any lubricant is better than none, I have known vegetable oil used in emergency situations :scratch: George. |

My Willson lathe uses Hydraulic oil in its gearbox AWS 68 if I recall, I think lots use hydraulic oil. Hydraulic oil will get flung far and wide in the gearbox, not an EP oil works fine on the gears and lobes in hydraulic pumps. |
| awemawson:
Beware that some gear oils will dissolve brass or bronze bushes found in older machinery. I think it's the sulphur content that does it and is there for the extreme pressure characteristics, but someone will correct me if I got that wrong :scratch: |

My new a Chinese lathe uses SAE20 grade for the gearbox...... :scratch: YMMV......... |
