I don’t remember doing this in the last 30 odd years, but I think it was about time. All stripped down, minor discovery that 2 of the 3 cap screws holding the back of the chuck to the body were metric, and one was imperial – Oh well, it was a Schools lathe before I bought it.
Once all parts (which I labeled with the jaw numbers) were cleaned in paraffin and dried, re-assembled. Happy bunny now. As far as lubrication, very light oil on the pinions and dry graphite powder on the “crown wheel /Pinions”.
